Use the formula for computing future value using compound interest to determine the value of an account at the end of 6 years if a principal amount of $6,000 is deposited in an account at an annual interest rate of 6% and the interest is compounded quarterly.
Answer: the value of the account at the end of 6 years is is $8577
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 6000
r = 6% = 6/100 = 0.06
n = 4 because it was compounded 4 times in a year.
t = 6 years
Therefore,.
A = 6000(1+0.06/4)^4 × 6
A = 6000(1+0.015)^24
A = 6000(1.015)^24
A = $8577

Let P(x) and Q(x) be predicates and suppose D is the domain of x. For the statement forms in each pair, determine whether (a) they have the same truth value for every choice of P(x), Q(x), and D, or (b) there is a choice of P(x), Q(x), and D for which they have opposite truth values.
∃x∈D,(P(x)∧Q(x))
(∃x∈D,P(x))∧(∃x∈D,Q(x))
Answer / Step-by-step explanation:
Given the statement:
∃x∈D,(P(x)∧Q(x)) and (∃x∈D,P(x))∧(∃x∈D,Q(x)) ,
Then,
(a), The variable used in a ∃ statement does not matter, thus, we can change the appearance of one of the variable used in the ∃ statement.
That is:
(∃x∈D,P(x))∧(∃x∈D,Q(x)) = (∃x∈D,P(x))∧(∃y∈D,Q(y))
Where
(∃x∈D,P(x))∧(∃x∈D,Q(x)) = (∃x∈D,P(x))∧(∃y∈D,Q(y)) implies that P(x) is true for some element x in D and Q(y) is true for some element y in D. However, x and y are not necessary the same element and thus, we cannot be sure that
P(x) ∧ Q(x) or P(y) ∧ Q(y) is true.
Moreover, if P(x) is only true for x and no other element in the domain D, and if Q(y) is only true for y and no other element in the domain D, while x ≠ y,
Then, P(x) ∧ Q(x) is false and P(y) ∧ Q(y) is also false. Moreover, there is no other known element (z) such that P(z) ∧ Q(z) is true and thus the statement
∃x∈D,(P(x)∧Q(x)) is false while the statement (∃x∈D,P(x))∧(∃x∈D,Q(x)) is true.
(b)
If the statement P(x) is only true for x and no other element in the domain D, and if Q(y) is only true for y and no other element in the domain D, while x ≠ y, then Then, P(x) ∧ Q(x) is false and P(y) ∧ Q(y) is also false. Moreover, there is no other known element (z) such that P(z) ∧ Q(z) is true and thus the statement
∃x∈D,(P(x)∧Q(x)) is false while the statement (∃x∈D,P(x))∧(∃x∈D,Q(x)) is true.
So in summary, we can say for:
(a) the statement does not contain the same truth value.
(b) The statement depicts there is such a choice in the first place.
In this exercise we have to use the knowledge of sets to identify which of the statements is true and false, thus we can state that:
A) the statement does not contain the same truth value.
B) The statement depicts there is such a choice in the first place.
Then, the first statement says that:
A)The variable used in a ∃ statement does not matter, thus, we can change the appearance of one of the variable used in the ∃ statement. That is:
[tex](\exists \ x \in D,P(x)) \wedge ( \exists \ x\in D,Q(x)) = (\exists \ x \in D,P(x)) \wedge (\exists \ y \in D,Q(y))[/tex]
Where the equation above implies that P(x) is true for some element x in D and Q(y) is true for some element y in D.
However, x and y are not necessary the same element and thus, we cannot be sure that is true.
If P(x) is only true for x and no other element in the domain D, and if Q(y) is only true for y and no other element in the domain D. Then, [tex]P(x) \wedge Q(x)[/tex] is false and [tex]P(y) \wedge Q(y)[/tex] is also false.
B) If the statement P(x) is only true for x and no other element in the domain D, and if Q(y) is only true for y and no other element in the domain D. Then, [tex]P(x) \wedge Q(x) \ or \ P(y) \wedge Q(y)[/tex] is also false.
Moreover, there is no other known element (z) such that is true and thus the statement.

A 4-foot tall child walks directly away from a 12-foot tall lamppost at 2 mph. How quickly is the length of her shadow increasing when she is 6 feet away from the lamppost (rounded to the nearest tenth of a foot per second)
Answer:
The length of the shadow is increasing with the rate of 1.5 feet per sec
Step-by-step explanation:
Let AB and CD represents the height of the lamppost and child respectively ( shown below )
Also, let E be a point represents the position of child.
In triangles ABE and CDE,
[tex]\angle ABE\cong \angle CDE[/tex] ( right angles )
[tex]\angle AEB\cong \angle CED[/tex] ( common angles )
By AA similarity postulate,
[tex]\triangle ABE\sim \triangle CDE[/tex]
∵ Corresponding sides of similar triangles are in same proportion,
[tex]\implies \frac{AB}{CD}=\frac{BE}{DE}[/tex]
We have, AB = 12 ft, CD = 4 ft, BE = BD + DE = 6 + DE,
[tex]\implies \frac{12}{4}=\frac{6+DE}{DE}[/tex]
[tex]12DE = 24 + 4DE[/tex]
[tex]8DE = 24[/tex]
[tex]DE=3[/tex]
Now, the speed of walking = 2 mph = [tex]\frac{2\times 5280}{3600}\approx 2.933\text{ ft per sec}[/tex]
Note: 1 mile = 5280 ft, 1 hour = 3600 sec
Thus, the time taken by child to reach at E
[tex]= \frac{\text{Walked distance}}{\text{Walking speed}}[/tex]
[tex]=\frac{6}{2.933}[/tex]
= 2.045 hours
Hence, the change rate in the length of shadow
[tex]= \frac{\text{Length of shadow}}{\text{Time taken}}[/tex]
[tex]=\frac{3}{2.045}[/tex]
= 1.5 ft per sec.

[tex]=\sqrt[4]{x^8.x^2}[/tex] ( using the property [tex]a^m.a^n=a^{m+n}[/tex] )
[tex]=\sqrt[4]{x^{2\times 4}.x^2}[/tex]
[tex]=\sqrt[4]{(x^2)^4x^2}[/tex] ( using the peoperty [tex]a^{mn}=(a^m)^n[/tex] )
[tex]=\sqrt[4]{(x^2)^4}\times \sqrt[4]{x^2}[/tex] ( using the property [tex]\sqrt{ab}=\sqrt{a}\times \sqrt{b}[/tex] )
[tex]=x^2\sqrt[4]{x^2}[/tex]
Therefore [tex]\sqrt[4]{x^{10}}=x^2\sqrt[4]{x^2}[/tex]
Therefore the equivalent expression to the given expression is [tex]x^2\sqrt[4]{x^2}[/tex]

When equal amounts are invested in each of three accounts paying 7%, 9%, and 12.5%, one years combined interest income is $1,225.5. How much is invested in each account?
Answer:
$4300.
Step-by-step explanation:
Let x represent amount of money invested in each account.
We have been given that equal amounts are invested in each of three accounts paying 7%, 9%, and 12.5%, one years combined interest income is $1,225.5.
We will use simple interest formula to solve our given problem.
[tex]I=Prt[/tex], where,
I = Amount of interest after t years,
P = Principal amount,
r = Annual interest rate.
Since principal for each amount is equal and time is equal to 1 year, so we can represent our given information in an equation as:
[tex]1225.5=x(0.07+0.09+0.125)(1)[/tex]
[tex]1225.5=x(0.285)[/tex]
[tex]x=\frac{1225.5}{0.285}[/tex]
[tex]x=4300[/tex]
Therefore, an amount of $4300 is invested in each account.
Final answer:
The amount invested in each of the three accounts with different interest rates, which together yield a total interest income of $1,225.5, is $4,300 in each account.
Explanation:
To solve for the amount invested in each account, we need to set up an equation that represents the total interest income from the accounts.
Letting x represent the amount invested in each account, we can say that the interest from the first account at 7% is 0.07x, the second account at 9% is 0.09x, and the third account at 12.5% is 0.125x. The total interest income is the sum of these individual interests, which equals $1,225.5. Hence, the equation to solve is:
0.07x + 0.09x + 0.125x = 1,225.5
Combining like terms gives:
0.285x = 1,225.5
Dividing both sides by 0.285 gives us:
x = 1,225.5 / 0.285
x = 4,300
Therefore, the amount invested in each account is $4,300.

A rectangle initially has width 7 meters and length 10 meters and is expanding so that the area increases at a rate of 8 square meters per hour. If the width increases by 40 centimeters per hour how quickly does the length increase initially
Final answer:
The length of the rectangle increases at a rate of 4/7 meters per hour (approximately 0.57 m/h) initially when the area is increasing at 8 square meters per hour and the width at 0.4 meters per hour.
Explanation:
To find how quickly the length of the rectangle increases, given that the area increases at a rate of 8 square meters per hour and the width increases by 40 centimeters (0.4 meters) per hour, we can use the area formula for a rectangle (Area = length × width). The rate of change of the area with respect to time (ΔA/Δt) can be related to the rates of change of the length and width with respect to time (ΔL/Δt and ΔW/Δt respectively) by the product rule for differentiation if we consider length and width as functions of time.
Initially, the area A is 10m × 7m = 70m². When the area is increasing at 8m²/h and the width is increasing at 0.4m/h, we can write the relation as follows:
ΔA/Δt = ΔL/Δt × W + L × ΔW/Δt
Substituting the given values and solving for the rate of change of the length (ΔL/Δt):
8 = ΔL/Δt × 7 + 10 × 0.4
8 = 7ΔL/Δt + 4
7ΔL/Δt = 4
ΔL/Δt = 4/7 m/h
Therefore, the length increases at a rate of 4/7 meters per hour (approximately 0.57 m/h) initially.

Find m∠R.
Write your answer as an integer or as a decimal rounded to the nearest tenth.
m∠R = °
The measure of the angle R is [tex]m \angle R=69.4[/tex]
Explanation:
It is given that the lengths of the triangle are PQ = 8 and QR = 3
To find the angle of R using the opposite and adjacent side, we shall use the tangent formula.
[tex]\tan \theta=\frac{o p p}{a d j}[/tex]
where opp = 8 and adj = 3
Thus, substituting these values in the formula, we get,
[tex]\tan \theta=\frac{8}{3}[/tex]
Multiplying both sides by [tex]tan^{-1}[/tex], we get,
[tex]\theta=tan^{-1} (\frac{8}{3})[/tex]
Dividing, we get,
[tex]\theta=69.44[/tex]
Rounding off to the nearest tenth, we have,
[tex]\theta=69.4[/tex]
Thus, the measure of the angle R is [tex]m \angle R=69.4[/tex]
A group of students formed a circle during a game.The circumference of the circle was about 43.96 feet,and the diameter of the circle was 14 feet.Which expression best represents the value of x?
Answer:
A group of students formed a circle during a game.The circumference of the circle was about 43.96 feet,and the diameter of the circle was 14 feet.Which expression best represents the value of π?
The expression which represents the value of π is option C from the attachment that is π = 43.96/14
Step-by-step explanation:
Given:
Circumference of the circle = 43.96 feet
Diameter f the circle = 14 feet
So,
We know that :
Circumference of the circle = [tex]2(\pi )r[/tex] or [tex](\pi)d[/tex]
Re-arranging the formula:
⇒ [tex](\pi)d = Circumference\ (C)[/tex]
⇒ [tex](\pi )d =C[/tex]
⇒ [tex]\frac{\pi\times d}{d}=\frac{C}{d}[/tex]
⇒ [tex]\pi =\frac{C}{d}[/tex]
Plugging the numeric values:
⇒ [tex]\pi =\frac{43.96}{14}[/tex]
So the expression for π is 43.96/ 14,and option C is the correct choice.
The required expression for value of x is [tex]\frac{43.96}{14}[/tex].
Given that,
The circumference of the circle was about 43.96 feet,
And the diameter of the circle was 14 feet
We have to determine,
Which expression best represents the value of x.
According to the question,
Circumference of the circle = 43.96 feet
Diameter f the circle = 14 feet
Then,
Circumference of the circle = [tex]\pi \times d[/tex]
Let, [tex]\pi = x[/tex]
Circumference of the circle [tex]= x d[/tex]
Circumference of the circle = 43.96 feet
Therefore,
[tex]= 43.96 = x\times 14\\\\= x = \frac{43.96}{14} \\\\[/tex]
Hence, The required expression for value of x is [tex]\frac{43.96}{14}[/tex].

In a large class of introductory Statistics students, the professor has each person toss a coin 16 times and calculate the proportion of his or her tosses that were heads. The students then report their results, and the professor plots a histogram of these several proportions. How much variability would you expect among these proportions?
Answer:
Variability expected among these Proportions is given by Standard deviation = 0.125
Step-by-step explanation:
The probability of tossing heads is the same for a fair coin as the probability of tossing tails.
The probability of tossing heads is then 1 chance out of 2
P = 1/2 = 0.5
The standard deviation of the sample distribution of the sample proportion = √Pq/n
Standard deviation = √p(1-p)/n
= √0.5(1-0.5)/16
Standard deviation = 0.125
The variability among the proportions of heads obtained in the coin tosses is due to the random nature of the experiment. The law of large numbers explains that as the number of tosses increases, the observed relative frequencies of heads will approach the theoretical probability of 0.5.
Explanation:The amount of variability that can be expected among the proportions of heads obtained by the students tossing a coin 16 times can be determined by understanding the concept of probability.
In a single coin toss, the probability of getting a head is 0.5. However, when the coin is tossed more times, the observed proportions of heads will vary from the theoretical probability of 0.5.
The variability among these proportions is attributed to the random nature of the coin tosses and is due to the fact that the short-term results of an experiment do not necessarily match the theoretical probability. The law of large numbers states that as the number of repetitions of an experiment is increased, the observed relative frequencies of heads will tend to become closer to the theoretical probability of 0.5.

Write your answer as an integer or as a decimal rounded to the nearest tenth.
CD =
Answer:
[tex]CD = 7.8[/tex]
Step-by-step explanation:
Given:
Δ DBC is a right angled triangle.
[tex]\angle B = 90\°\\\\\angle C = 59\°[/tex]
BC = 4
We need to find the value of CD
Solution:
Now we know that:
[tex]cos\ \theta = \frac{adjacent \ side}{hypotenuse}[/tex]
So we can say that;
[tex]Cos \angle C =\frac{BC}{CD}[/tex]
Substituting the given values we get;
[tex]Cos\ 59 = \frac{4}{CD}\\\\\\CD = \frac{4}{Cos\ 59} = 7.766[/tex]
Rounding to nearest tenth we get;
[tex]CD = 7.8[/tex]
Hence the Value of CD is 7.8.
Martha has 8 cubic feet ofputting soil in the three flowerpots she wants to put the same amount of soil in each pot how many cubic feet of soil she put in each flower pot
Answer:
[tex]2\frac{2}{3}\text{ ft}^3\approx 2.67\text{ ft}^3[/tex]
Step-by-step explanation:
We have been given that Martha has 8 cubic feet of putting soil in the 3 flowerpots. She wants to put the same amount of soil in each pot.
To find the amount of soil in each pot, we need to divide total soil (8 cubic feet) by number of pots (3) as shown below:
[tex]\text{Amount of soil in each pot}=\frac{8\text{ ft}^3}{3}[/tex]
[tex]\text{Amount of soil in each pot}=2\frac{2}{3}\text{ ft}^3[/tex]
[tex]\text{Amount of soil in each pot}=2.6666\text{ ft}^3[/tex]
[tex]\text{Amount of soil in each pot}\approx 2.67\text{ ft}^3[/tex]
Therefore, Martha needs to put approximately 2.67 cubic feet of soil in each flower pot.
To determine the amount of soil Martha puts in each flowerpot, divide the total cubic feet of soil (8) by the number of flowerpots (3), which results in approximately 2.67 cubic feet of soil per pot.
Explanation:The question pertains to the division of cubic feet of soil into equal amounts across three flowerpots. To find out how many cubic feet of soil Martha should put in each flower pot, we simply divide the total amount of soil by the number of flowerpots. In this case, Martha has 8 cubic feet of soil to distribute evenly into 3 pots.
The calculation would be as follows:
Determine the total volume of soil available: 8 cubic feet.Count the number of flowerpots: 3.Divide the total volume of soil by the number of pots to get the amount of soil per pot: 8 cubic feet ÷ 3 pots = 2.67 cubic feet per pot.Therefore, Martha can put approximately 2.67 cubic feet of soil in each flower pot.
Jody, a statistics major, grows tomatoes in her spare time. She measures the diameters of each tomato. Assume the Normal model is appropriate. One tomato was in the 50th percentile. What was its z-score?
Answer:
Zscore = 0.5
Step-by-step explanation:
If we assume a normal distribution, we mean that the diameters of each tomato follow a normal distribution. This is N~ (0,1).
By that, we mean that the mean (μ) = 0 and variance ([tex]\sigma^{2}[/tex]) = 1. Thus, since we are told that one tomato was in the 50th percentile. This implies the median. And is 0.5. And if the distribution is normal, the mean and median and mode should be equal.
Thus:
==> Z score = [tex]\frac{x-\mu}{\sigma}[/tex] = [tex]\frac{0.5 - \mu}{\sigma} = \frac{0.5-0}{1} = 0.5[/tex]
