Answer:

When the absolute value of the scale factor is less than one, a compression occurs. When the absolute value of the scale factor is equal to one, neither an expansion nor a compression occurs.

With 99% confidence that the true difference lies between 0.1316 and 0.2694.

A 99% confidence interval for the difference in average SAT scores between coached and uncoached students can be constructed using the data above.

The confidence interval is calculated as (mean of coached students - mean of uncoached students) +/- (2 * standard error of the difference in means).

The mean of coached students is (0.3098 + 0.3399 + 0.219 + 0.0798) / 4 = 0.2155, and the mean of uncoached students is (0.0046 + 0.0248) / 2 = 0.0147. The standard error of the difference in means can be calculated as the square root of ((0.2155(1-0.2155)/4) + (0.0147(1-0.0147)/2)).

The confidence interval is then (0.2155 - 0.0147) +/- (2 * 0.0347) = 0.201 +/- 0.0694, or (0.1316, 0.2694). This indicates that, on average, coached students gain 0.201 points more than uncoached students, with 99% confidence that the true difference lies between 0.1316 and 0.2694.

The sky appears blue because of Rayleigh scattering while water appears blue due to selective absorption and scattering of light.

The blue color of the sky is a result of Rayleigh scattering which occurs when the Earth's atmosphere scatters shorter wavelengths of light (blue and violet) more efficiently than longer wavelengths (red and orange).

When sunlight enters the atmosphere, the blue light is scattered in all directions by the molecules and tiny particles present in the air creating the blue appearance of the sky.

Similarly, water appear blue due to selective absorption and scattering of light. Water molecules selectively absorb colors from the visible light spectrum and absorb longer wavelengths (such as red) more effectively than shorter wavelengths (such as blue).

Answer:

Step-by-step explanation:

The solution for y in terms of x in the given equation is: y = (x - 10) / 2

To solve for y in terms of x, we can start by isolating y on one side of the equation.

Given the equation 2(y + 5) = x, we can start by expanding the expression inside the parentheses:

2y + 10 = x

Next, we can subtract 10 from both sides to isolate y:

2y = x - 10 [subtraction property of equality]

Finally, we can divide both sides by 2 to find y:

y = (x - 10) / 2 [division property of equality]

The value of x is 200

The number of texts is 1000

We have that:

1/ 5x - 2/3 y = 30

Where y = 15

Now, let's find the LCM

3x - 10y/ 15 = 30

cross multiply

3x - 10y = 450

substitute the value of y

3x - 10(15) = 450

3x - 150 = 450

collect like terms

3x = 450 + 150

3x = 600

x = 600/ 3

x = 200

To determine the number

$0. 05 is the cost per text

Base cost is $5

Limit is $25

= 25/ 0. 05 + 5

= 25/ 0. 025

=1000

Thus, the value of x is 200 and number of texts is 1000

Answer:

A

Step-by-step explanation:

From inspection of the graph, we can see that every time the x-value increases by 10, the y-value increases by 1000.

So, the employee earns an additional $1000 for every 10 units sold.

To calculate how much the employee earns for every 1 unit sold, divide $1000 by 10:

1000 ÷ 10 = 100

Therefore, the employee earns an additional $100 for every one unit sold.

Proof

This can be proved by calculating the slope (gradient) of the graph:

\(\sf slope=\dfrac{y_2-y_1}{x_2-x_1}\)

where \(\sf (x_1,y_1)\) and \(\sf (x_2,y_2)\) are two points on the line

When picking the two points, remember that the y-values are in thousands of dollars.

Two points on the line:

(0, 30000) and (20, 32000)

Substituting these into the formula:

\(\sf \implies slope=\dfrac{32000-30000}{20-0}=\dfrac{2000}{20}=100\)

Therefore, the employee earns an additional $100 for every one unit sold.

The statement that are consistent with the guidelines for hitching trailers are:

A. Trailers must be connected to the tow vehicle before loading.

D. Customer vehicles must have at least a frame mounted Class 3 receiver hitch with a 2" or 2 5/6" ball.

Option A: Because it guarantees that the weight of the cargo is evenly distributed and attached to the trailer before the vehicle is driven this recommendation is consistent with safe hitching techniques.

Option D: Because it guarantees that the trailer is securely fastened to the tow vehicle and can support the weight of the cargo this recommendation is consistent with safe hitching techniques. A 2" or 2 5/16" ball ensures the trailer is firmly fastened to the hitch and a Class 3 hitch is made to support the weight of heavier trailers.

Step-by-step explanation:

Because point Q ∈ PR (∈ means belongs to), we know that PQ + QR = PR due to the Parts Whole Postulate. Therefore, using substitution, we can write the following equation:

2 + 2x + 4 = 4x - 10

2x + 6 = 4x - 10

-2x = -16

x = 8 so PR = 4(8) - 10 = 22.

The required graph has been attached below that represents the function f(x) = 5 cos (2x).

The graph of the function f(x) = 5 cos(2x) is a periodic function that oscillates between its maximum and minimum values as x changes.

Specifically, the function is a cosine function with amplitude 5 and period π, since the coefficient of x is 2 in the argument of the cosine function.

The graph of the function f(x) = 5 cos(2x) has a maximum value of 5 when cos(2x) = 1 (i.e., at 2x = 0 + 2πk, where k is an integer), and a minimum value of -5 when cos(2x) = -1 (i.e., at 2x = π + 2πk, where k is an integer).

Thus, the graph has been attached below that represents the given function.

The ranking from the lowest to highest APR for the given companies is A, B, D, C.

The correct option is b.

To rank the companies from the lowest to highest Annual Percentage Rate (APR) based on a $600 loan amount, we need to calculate the APR for each company. The formula to calculate APR is APR = (Fees / Loan Amount) * (365 / Terms of Loan).

Let's calculate the APR for each company:

For Company A:

APR_A = ($60 / $600) x (365 / 18) = 0.1 x 20.28 = 2.028%

For Company B:

APR_B = ($80 / $600) x (365 / 12) = 0.1333 x 30.42 = 4.054%

For Company C:

APR_C = ($90 / $600) x (365 / 10) = 0.15 x 36.5 = 5.475%

For Company D:

APR_D = ($110 / $600) x (365 / 14) = 0.1833 x 26.07 = 4.79%

Now, we can rank the companies from the lowest to highest APR:

Company A - APR: 2.028%

Company B - APR: 4.054%

Company D - APR: 4.79%

Company C - APR: 5.475%

Since y varies directly with square root x, so

k is the constant of variation

We will find it using the initial values of x and y

Since the initial values are:

y = 49

x = 49

Substitute them in the rule to find k

The value of k is 7, so the equation will be

We need to find the value of y at x = 128, so

Substitute x in the rule by 128

Round it to two decimal places, so
