Answer:

3/7 and 4/14

Step-by-step explanation:

a) 3/7 is not an equivalent of 6/21 because when you multiply the numerator and the denominator by 2 you get: 6/14

b) 4/14 is not an equivalent

Answer:

3/7

Step-by-step explanation:

6/21 = 6 ÷ 3 / 21 ÷ 3 = 2 / 7

6 / 21 = 4 ÷ 2 / 14 ÷ 2 = 2 / 7

6/21 = 12 ÷ 6 / 42 ÷ 6 = 2 / 7

Given the provided conditions which are a known population standard deviation and a sample size (n = 40) greater than 30, the critical value of Za/2 is appropriate for calculating the margin of error in a skewed population.

In this scenario, a 95% confidence interval is being constructed for a population that is skewed. Given a sample size, n, of 40, the population standard deviation (σ) is 2.6. When we construct confidence intervals for such a scenario, we refer to either a Z-distribution (critical value of Za/2) or a T-distribution (critical value of ta/2) based on certain conditions.

A critical value of Za/2 is used when the population standard deviation is known, and the sample size is large enough (typically n > 30). A critical value of ta/2 is referred to when the population standard deviation is unknown, or the sample size is too small (typically n < 30).

In this case, the population is skewed, the standard deviation is known, and the sample size (n = 40) is larger than 30. Therefore, we should use the critical value of Za/2 for calculating the margin of error.

D.)<-50.5, 58.1>

Step-by-step explanation:

The vector can be decomposed into its x and y components using trigonometry.

The x and y components of the vector, together with the vector length forms a right triangle, as shown in the figure attached.

The x-component of the vector is given by

[tex]sin (-41^o)=\dfrac{x}{77}[/tex]

[tex]x=77*sin (-41^o)[/tex]

[tex]x=-50.5[/tex]

And the y-component of the vector is given by

[tex]cos(-41^o)=\dfrac{y}{77}[/tex]

[tex]y=77*cos(-41^o)[/tex]

[tex]y=58.1[/tex]

Thus, the vector as an ordered pair is represent by

[tex]\boxed{ (-50.5, 58.1)}[/tex]

which is choice D.

Simple interest formula: A= P(1+Ryan)

A = 12000(1+ 0.07x4) = 15,360.00

Amount of interest = 15360-12000= 3,360.00

A= 12000(1+0.08x5) = 16,800.00

Interest = 16,800-12,000 = 4,800.00

Difference in interest = 4800 - 3360 = $1,440.00

Suppose it is given that two triangles ΔABC ≅ ΔDEF

Then that means ΔABC and ΔDEF are congruent. Congruent triangles are exact same triangles, but they might be placed at different positions.

The order in which the congruency is written matters.

For ΔABC ≅ ΔDEF, we have all of their corresponding elements like angle and sides congruent.

Thus, we get:

[tex]\rm m\angle A = m\angle D \: or \: \: \angle A \cong \angle D \angle B = \angle E\\\\\rm m\angle B = m\angle E \: or \: \: \angle B \cong \angle E \\\\\rm m\angle C = m\angle F \: or \: \: \angle C \cong \angle F \\\\\rm |AB| = |DE| \: \: or \: \: AB \cong DE\\\\\rm |AC| = |DF| \: \: or \: \: AC \cong DF\\\\\rm |BC| = |EF| \: \: or \: \: BC \cong EF\\[/tex]

(|AB| denotes length of line segment AB, and so on for others).

For these cases, the two triangles in the image are congruent.

So their corresponding sides must be of same measures.

The three sides of triangle RST are of measures 75, 67 and 50 miles

The two sides of triangle NLM are 67 miles and 75 miles. So obviously third one can be nothing except 50 miles so that the triangle NLM also have sides of same measure as of the triangle RST.

Thus, the length of NM line segment for the considered situation is given by: Option D: 50 mi

Final answer:

The combined probability of the coin landing tails-up and the number cube landing on a 4 is 8.33%.

Explanation:

The question involves calculating the probability of two independent events: the coin landing tails-up and the dice landing on a 4. The probability of a coin landing on tails is 0.5, and the probability of a dice landing on a particular number, say 4, is 1/6 since a dice has six faces. Since these two events are independent, their combined probability is found by multiplying the probabilities of each event.

The probability of the coin landing tails-up is 0.5, and the probability of the number cube (dice) landing on a 4 is 1/6. So, the combined probability of both events occurring is (0.5) × (1/6) = 0.0833, or 8.33% when expressed as a percentage.

The five linear equations produce five parallel contour lines. The value of z increases as the lines shift to the right.

Final answer:

Level curves for the function f(x, y) = 5x - y for different values of c are straight lines with a slope of 5. They can be plotted on the same coordinate axes to form a contour map, with each line corresponding to one value of c.

Explanation:

Level Curves for the Function f(x, y) = 5x - y

To find the level curves of the function f(x, y) = 5x - y for the given values of c, we set f(x, y) equal to each constant and solve for y in terms of x:

For c = -2: -2 = 5x - y → y = 5x + 2

For c = -1: -1 = 5x - y → y = 5x + 1

For c = 0: 0 = 5x - y → y = 5x

For c = 1: 1 = 5x - y → y = 5x - 1

For c = 2: 2 = 5x - y → y = 5x - 2

These equations represent lines with a slope of 5 and various y-intercepts. The level curves can be drawn on a set of coordinate axes by plotting the lines according to their y-intercepts. Each line represents a different level curve and the set of these lines can be referred to as a contour map.

Step-by-step explanation:

Given:

Mr. Norris is paid a 5% commission on each boat he sells.

Now, to find his commission on a boat that he sells for $125,000.

Commission = 5%.

Boat he sell for = $125,000.

Now, to get the commission on the boat he sells:

5% of $125,000.

[tex]=\frac{5}{100} \times 125000[/tex]

[tex]=0.05\times 125000[/tex]

[tex]=\$6250.[/tex]

Therefore, his commission on the boat he sells is $6250.

Final answer:

Mr. Norris's commission on a boat sold for $125,000, with a commission rate of 5%, is $6,250.

Explanation:

Mr. Norris earns a commission based on a fixed percentage of the sales price. To calculate his commission for selling a boat priced at $125,000, we apply the 5% commission rate to the sale price.

Here's the calculation:
Commission = Sale Price × Commission Rate
Commission = $125,000 × 0.05
Commission = $6,250

Hence, Mr. Norris's commission for selling a boat that he sells for $125,000 is $6,250.

The domain of the translated cube root function y = ∛(x - 1) + 3 is {x | x is a real number}, since cube root functions accept all real numbers.

The graph of the function y = ∛(x - 1) + 3, which is a cube root function, is a translated version of the parent function y = ∛x. The translation involves shifting the graph to the right by 1 unit and up by 3 units. Given that a cube root function, like y = ∛x, can accept any real number as an argument because there are real cube roots for all real numbers, the domain of the translated function would also be all real numbers. This remains true even after the function is translated. Hence, the domain of the graphed function is {x | x is a real number}.

Answer:

135m^2

Step-by-step explanation:

length = l

width = w

l + l + w + w = 48

l = w+6

w+6 + w+6 + w + w = 48

4w + 12=48

4w=36

w=9

l=15

15*9=135

Answer:

A = 135m²

Step-by-step explanation:

Write equations to represent the problem.

l = w + (6m)        The length is 6m more than the width

P = (48m)        Perimeter is 48m

***We put brackets around numbers with the "m" to avoid confusing the units with a variable.

The formula for perimeter of a rectangle is P = 2(l + w)

Substitute "l" and "P" into the perimeter formula with the equations above. Simplify, then isolate "w".

P = 2(l + w)        

(48m) = 2(w + (6m) + w)        Collect like terms (w + w = 2w)

(48m) = 2(2w + (6m))        Distribute over brackets

(48m) = 4w + (12m)        Start isolating "w"

(48m) - (12m) = 4w + (12m) - (12m)        Subtract 12m from both sides

(36m) = 4w        

4w/4 = (36m)/4        Divide both sides by 4

w = 9m        Width of rectangle

Find "l" using the formula for length. Substitute the width.

l = w + (6m)        

l = (9m) + (6m)        Add

l = 15m        Length of rectangle

Use the formula for the area of a rectangle A = lw.

Substitute the values we found for length and width.

A = lw        

A = (15m)(9m)        Multiply

A = 135m²        Area of rectangle

Therefore the area of the rectangle is 135m².

[tex]f\left(x\right)=a\left|x-h\right|+k[/tex]

where

The variable a, tells us how far the graph stretches vertically, and whether the graph opens up or down

(h,k) is the vertex of the absolute value

In this problem we have

[tex]f\left(x\right)=0.7\left|x-4\right|+2[/tex]

we have

[tex]a=0.7[/tex]

The coefficient a is positive ----> the graphs open up

The vertex is the point (4,2)

Find the piecewise model

case 1) positive value

[tex]f(x)=0.7[(x-4)]+2[/tex]

[tex]f(x)=0.7x-2.8+2\\f(x)=0.7x-0.8[/tex]

Is a linear equation with positive slope

[tex](x-4)\geq 0\\x\geq 4[/tex]

The domain is the interval [4,∞)

case 2) negative value

[tex]f(x)=0.7[-(x-4)]+2[/tex]

[tex]f(x)=-0.7x+2.8+2\\f(x)=-0.7x+4.8[/tex]

Is a linear equation with negative slope

[tex](x-4)< 0\\x<4[/tex]

The domain is the interval (-∞,4)

[tex]x<4[/tex]

therefore

The piecewise model of the function is

[tex]f(x)=-0.7x+4.8[/tex] -----> For [tex]x<4[/tex]

[tex]f(x)=0.7x-0.8[/tex] -------> For [tex]x\geq 4[/tex]

128 = 8 * 16

160 = 8 * 20

11 - 10 = 1

x - 11 = 2

16 - x = 3

20 - 16 = 4

x = 13

13 * 8 = 104

The two numbers being asked in the question are 4 and -1.

This question can be solved using a system of linear equations. Let's call the first number x and the second number y.

From the first statement, we can create one equation: 2x + 4y = 4

From the second statement, we can create another equation: x - y = 5

To solve this system, we can use substitution or elimination method. If we multiply the second equation by 2, we get 2x - 2y = 10. Now, we can subtract the second equation from the first: (2x + 4y) - (2x - 2y) = 4 - 10, which simplifies to 6y = -6. Dividing both sides by 6, we get y = -1.

Substitute y = -1 into the equation x - y = 5, we get x - (-1) = 5. Therefore, x = 5 - 1 = 4.

So, the first number x is 4 and the second number y is -1.
