Answer:

The union of two event

Step-by-step explanation:

Addition law of probability  define that probability of two event  is total sum of probability of any event subtract the probability of both events

There are two rules  in addition law:

Addition law 1 -  when both event are mutually exclusive, then probability of either event is the sum of each event probability.

P( A or B) = P(A) +P(B)

Addition law 2 -  when both events are non mutually exclusive then there in addition to the individual probability there is some overlap .

P( A or B) = P(A) +P(B) - P(A and B)

It should be noted that addition law is potentially helpful when we are interested in computing the probability of The union of two event.

According to this question, we are to discuss about Addition law of probability.

As a result of this we can see that Addition law of probability  explain about probability for either of two mutually exclusive events which is occurring and also  the probability of two non-mutually exclusive events that is occurring.

Answer: To produce treatment groups with similar characteristics

Step-by-step explanation:

The purpose of this experiment is to determine that the treatments groups with similar characteristics are produced. Every groups is taking different amount of the supplement so this study ensures that by randomly assigning the supplements, we can check the cholesterol level in the blood. In this way, similar characteristics in groups are imparted so we can then make treatment groups of same characteristics.

The purpose of random assignment in experiments is to avoid bias, increase the research results' accuracy, help in producing treatment groups with similar characteristics, and control confounding variables. In this case, it ensures that all participants have an equal chance of receiving any level of omega-3 fatty acid or placebo.

The purpose of random assignment in this experiment is multifold. Firstly, it ensures all participants, regardless of their cholesterol levels, have an equal chance of being selected. This prevents bias in the sample selection. Secondly, it increases the accuracy of the research results by preventing skewness in the data. The random assignment ensures that every participant has an equal chance of receiving any level of the omega-3 fatty acid supplement or the placebo. This helps produce treatment groups with similar characteristics, which in turn allows for fair comparisons to be made. Finally, it aids in controlling confounding variables. These are factors other than the independent variable (in this case, omega-3 fatty acid supplements) that may affect the dependent variable (cholesterol level), and random assignment helps to equalize these among the groups.

Answer:

7.41 m/s

Step-by-step explanation:

Force of a car inclined at an angle

F=mg Sin Θ where; m = 2956 kg , g = 9.8m/s² , Θ = 35⁰

F = 2956 x 9.8 x Sin 35 = 16615.82 N

Net force due to friction = 16615.82 - 3080 = 13535.82 N

To calculate acceleration; F= Ma

13535.82 = 2956 x a

a = 4.58 m/s²

From equation of motion

[tex]V^{2} = V_{o} ^{2} + 2aS[/tex]

V² =  0 + (2 x 4.58 x 6)

V = [tex]\sqrt{54.95}[/tex]

Answer:

152x miles

Step-by-step explanation:

Jose runs x miles per day each week for 5 days.

For 3 days of the week he runs at a speed of 8 minutes per mile. So we have

3*8*x = 24x

For 2 days he runs 7 minutes per miles. We have

2*7*x = 14x

in one week, he runs 24x + 14x = 38x

In 4 weeks, he runs

4*38x = 152x miles

Answer:

The solution of the inequality required for the situation is d  ≥ $13.46.

Step-by-step explanation:

i) the minimum deposit is $10.

ii) the balance before the statement is $-3.46

iii) a deposit d is made so that the fee did not have to be made

iv) therefore d + (-3.46)  ≥  10

                    d - 3.46 ≥ 10

    therefore d  ≥ 10 + 3.46

 therefore d  ≥ $13.46

Chris would have to deposit at least $13.46 into her account in order to avoid being charged a fee. This amount is determined by setting up and solving the inequality -3.46 + d ≥ 10, which represents her account balance.

In this situation, Chris is trying to avoid a fee by maintaining a balance of at least $10 in her account. Prior to making a deposit, her account balance is -$3.46. Thus, we need to find out the minimal deposit, d, that she needs to make in order to bring her balance up to $10. To do this, we can set up the following inequality:

-3.46 + d ≥ 10

To solve the inequality for d, we simply add 3.46 to both sides of the inequality:

d ≥ 13.46

Therefore, Chris must make a deposit of at least $13.46 to avoid incurring the fee.

Step-by-step explanation:

for a rectangle

area = length x width, (rearranging)

width = area / length

given area = 45x⁸y⁹ and length = 5x³y⁴

width = 45x⁸y⁹ / 5x³y⁴

= (45/5) ( x⁸y⁹ / x³y⁴)

Answer:

Step-by-step explanation:

let 4th fourth vertex be D (x,y)

A(2 1/3,7 1/2),B(12, 7 1/2),C(12,1)

or A(7/3,15/2),B(12,15/2),C(12,1)

Mid-point of diagonal AC is  P((7/3+12)/2,(15/2+1))

Mid -point of diagonal BD is P((12+x)/2,(15/2+y)/2)

(Because mid -point of diagonal is same.)

(12+x)/2=(7/3+12)/2

12+x=7/3+12

x=7/3

(15/2+1)/2=(15/2+y)/2

15/2+1=15/2+y

y=1

so fourth vertex is (7/3,1)

To find the coordinates of the fourth vertex of the rectangle, we use the information provided about the positions of the third vertex and the Car X figure. The coordinates of the fourth vertex are (13 2/3, 7 1/2) and (12, 2).

To find the coordinates of the fourth vertex of the rectangle, we can use the fact given that the third vertex is one and two-thirds perpendicular hash marks to the right of the center top hash mark. Since the center top hash mark is at (12, 7 1/2), the third vertex is at (12 + 1 2/3, 7 1/2), which simplifies to (13 2/3, 7 1/2).

Now, we need to find the position of the fourth vertex. According to the given information, the fourth vertex is in the same position as the Car X figure, which means it is one perpendicular hash mark above the center right hash mark. Since the center right hash mark is at (12, 1), the fourth vertex is at (12, 1 + 1), which simplifies to (12, 2).

Therefore, the coordinates of the fourth vertex are (13 2/3, 7 1/2) and (12, 2).

Answer:

Option c

Step-by-step explanation:

given that limit x tending to 4 of the function (3x-4) is 8

This implies for all values of x such that for epsilon >0 arbitrary small ,

[tex]||x-4||<\epsilon[/tex], we get

|f(x)-8|<3epsilon

this is equivalent to the option c.

Proof:

Consider

[tex]||x-4||<\epsilon\\3||x-4||<3\epsilon\\||3x-12||<3\epsilon\\||3x-4|-8| <3\epsilon[/tex]

Hence it follows that option C is right.

The correct statement to use when proving that limx→4(3x−4)=8 is option b: Given 0 < | x - 4 | < epsilon/3, then | (3x - 4) - 8 | < epsilon. This uses the formal definition of limit and abides the epsilon-delta parameters definition to provide the correct proof.

To verify the given limit, we need to utilize the formal definition of a limit. This formal definition gives us a systematic method to prove a limit based on epsilon-delta parameters. The purpose is to show that as x gets closer and closer to 4 (with| x - 4 | being smaller than an arbitrary positive delta), the expression (3x-4) increasingly approaches 8 (with |(3x - 4) - 8| getting within an epsilon range).

The correct choice is: b. Given 0 < | x - 4 | < epsilon/3, then | (3x - 4) - 8 | < epsilon. In this case, 'epsilon/3' in | x - 4 | < 'epsilon/3' is the delta in the epsilon-delta definition of limit. Essentially, it captures the notion that for every epsilon > 0, there exists a delta > 0 such that 0 < | x - 4 | < delta implies | (3x - 4) - 8 | < epsilon, thereby proving the limit.

To solve any equation that is linear in the variable of interest, you first look at what is done to the variable, using the Order of Operations as your guide.

Here, the variable is ...

You find the value of the variable by reversing these steps, starting from the last one on the list and working up the list.

To "undo" the addition of "b", we add its opposite (-b) to the equation. The rules of equality tell you that anything you do to one side of the equation must also be done to the other side, so we add -b to both sides:

  ax +b -b = c -b

  ax = c -b . . . . . . . . simplify

To "undo" the multiplication by "a", we multiply by its reciprocal. That is, we multiply by 1/a, or, equivalently, divide by "a". Again, we must do this to both sides of the equation:

  (1/a)ax = (1/a)(c -b)

  x = (c -b)/a . . . . . . . simplify

In short, we subtract the added constant (b) and divide by the multiplier (a).

Answer:

The probability of selecting two winners from Wells is, [tex]\frac{z(z-1)}{(x+y+z)(x+y+z-1)}[/tex]

Step-by-step explanation:

Let us assume that x people entered the drawing were from Gaston, y people entered the drawing were from Pike and z people entered the drawing were from Wells.

Total number of people who entered the drawing is, N = x + y + z.

It is provided that 2 winners are selected at random.

The event of selecting the first and second winner are not related, i.e. they are independent.

Then the first winner can be selected from Wells in z ways.

And the second winner can be selected, also from Wells in (z - 1) ways.

The probability of selecting both the winners from Wells is:

[tex]P(Both\ the\ winners\ were\ from\ Wells)=\frac{z}{x+y+x}\times \frac{z-1}{x+y+z-1} =\frac{z(z-1)}{(x+y+z)(x+y+z-1)}[/tex]

The factored form is  [tex](8x-32)=8(x-4)[/tex]

Step-by-step explanation:

Given : A youth club receives a discount on each pizza purchased for a party. The original price of each pizza is x dollars. The club leader purchases 8 pizzas for a total of (8x-32) dollars.

To find : Factor the expression ?

Solution :

The original price of each pizza is x dollars.

The club leader purchases 8 pizzas for a total of [tex](8x-32)[/tex] dollars.

To factor the expression we have to take common term out.

So, [tex]8x=8\times x[/tex]

[tex]32=8\times 4[/tex]

8 is common take out,

[tex](8x-32)=8(x-4)[/tex]

Factors are 8 and (x-4).

Therefore, the factored form is  [tex](8x-32)=8(x-4)[/tex]

To factor the expression (8x - 32), we take out the common factor of 8, resulting in the factored form of 8(x - 4), indicating a $4 discount per pizza.

The question is asking to factor the expression, which represents the total cost for purchasing 8 pizzas after receiving a discount from the original price x dollars per pizza. The expression given is (8x - 32) dollars.

To factor this expression, we look for a common factor in both terms which is 8.

Factoring out the 8, we get 8(x - 4). This means the club receives a discount of $4 per pizza since (8x - 32) factors into 8 times (x - 4).

Step-by-step explanation:

so this is a two step problem

c=18.5+0.11x

we created the function

now we plug in 329 into x and solve to get the c

c=54.69

The monthly cost for pre-paid cell phone usage can be expressed as a function, C = 18.5 + 0.11x where x is the number of calling minutes. The monthly cost for making 329 minutes of calls would be $54.69.

The pre-paid cell phone company charges a fixed monthly access fee and an additional cost per minute of calling time. Here, the monthly access fee is $18.5 and the cost per minute is $0.11. We are asked to express the monthly cost C as a function of x, the number of minutes used.

Therefore, we can write the function as C = 18.5 + 0.11x where, C represents the monthly cost and x represents the number of minutes used.

Now, if you make 329 minutes of calls this month, you can use this function to calculate the total cost. Substituting x = 329 into the function gives: C = 18.5 + 0.11 * 329 = $54.69.

Therefore, the monthly cost for making 329 minutes of calls would be $54.69.

Answer:

Correct option is (C).

The possible value of the p-value for a one-tailed test are 0.22 and 0.78.

Step-by-step explanation:

The p-value is the probability of acquiring a result as extreme as the observed result, assuming the null hypothesis statement is true.

The p value of a test is:

Left-tailed test: [tex]P(TS<ts)[/tex]

Right-tailed test: [tex]P(TS>ts) = 1- P(TS<ts)[/tex].

Here,

TS = Test statistic

ts = computed value of the test statistic.

The two-tailed p-value is: [tex]2P(TS<ts)[/tex] or [tex]2P(TS>ts)[/tex].

The p-value of the two tailed test is, 0.44.

Compute the p-value for one-tailed test a follows:

            [tex]2P(TS<ts)=0.44\\P(TS<ts)=\frac{0.44}{2}\\ =0.22[/tex]

            [tex]P(TS>ts) = 1- P(TS<ts)\\=1-0.22\\=0.78[/tex]

Thus, the possible value of the p-value for a one-tailed test are 0.22 and 0.78.

The correct option is (C).

Given a p-value of 0.44 from a two-tailed test, the equivalent one-tailed test would yield a p-value of 0.22. Out of the provided choices, option C is closest to the correct interpretation.

The question presented is about the computation of the p-value in a one-tailed test, given the p-value from a two-tailed test. A p-value essentially indicates the probability that you would obtain the observed data, or data more extreme if the null hypothesis is true. In this instance, the experimenter has a p-value of 0.44 from a two-tailed test.

When converting this to a one-tailed test, the p-value would effectively be halved. Therefore, if they conducted a one-tailed test on the same data, the p-value would be 0.22 (i.e., 0.44/2) in the direction specified by the alternative hypothesis. Thus, between the provided options, none are perfectly correct, but option C) 'The possible p-values are 0.22 and 0.78.' is closest to the correct interpretation, with the accurate p-value being 0.22 rather than 0.78.

Answer:

It takes 60 hours for Alex to complete the job alone.

Step-by-step explanation:

Given:

Number of hours Brandon alone can finish job =20 hours

Let the number of hours required by Alex alone to complete the job be 'x' hrs.

We need to find the number of hours required by Alex alone to complete the job.

Solution:

Now we can say that;

Rate at which Alex can complete the job alone = [tex]\frac1x[/tex] job/hour

Rate at which Brandon can complete the job alone = [tex]\frac{1}{20}[/tex] job /hour

Also Given:

Number of hours required for both to complete the job = 15

So rate of both complete the job  = [tex]\frac{1}{15}[/tex] job/hour

Now we can say that;

rate of both complete the job is equal to sum of Rate at which Alex can complete the job alone and Rate at which Brandon can complete the job alone.

framing in equation form we get;

[tex]\frac1x+\frac{1}{20}=\frac{1}{15}[/tex]

Now taking LCM for making the denominators same we get;

[tex]\frac{20}{20x}+\frac{x}{20x}=\frac{1}{15}[/tex]

Now denominators are common so we will solve the numerators.

[tex]\frac{20+x}{20x}=\frac{1}{15}[/tex]

Now Using cross multiplication we get;

[tex]15(20+x)=20x[/tex]

Applying Distributive property we get;

[tex]15\times20+15\times x =20x\\\\300+15x=20x[/tex]

Combining like terms we get;

[tex]300=20x-15x\\\\300=5x[/tex]

Now Dividing both side by 5 we get;

[tex]\frac{300}{5}=\frac{5x}{5}\\\\x=60\ hrs[/tex]

Hence It takes 60 hours for Alex to complete the job alone.

To find how long it will take Alex to complete the job by himself, we first establish the individual work rates of Alex and Brandon. We know the combined work rate (1/15 jobs per hour) and Brandon's work rate (1/20 jobs per hour). Alex's work rate is thus 1/15 - 1/20 = 1/60 jobs per hour, which means it will take him 60 hours to do the job alone.

This question requires knowledge of work rate calculations in Mathematics. The scenario involves two workers, Alex and Brandon, who can complete a cleaning task together in 15 hours. It's also given that Brandon can do the job alone in 20 hours, and we need to calculate how long it would take for Alex to complete the job by himself.

First, let's define their rates of work. If Brandon can complete the job in 20 hours, his work rate is 1 job per 20 hours, or 1/20 jobs per hour. Similarly, if Alex and Brandon together can complete the job in 15 hours, their combined work rate is 1 job per 15 hours, or 1/15 jobs per hour.

To find Alex's work rate, we subtract Brandon's work rate from the combined work rate. Thus, Alex's work rate is 1/15 - 1/20 = 1/60 jobs per hour. This means it would take Alex 60 hours to complete the job on his own.
