Step 1: Define

(-3v + 1) + 7 - (6v + 6) = -37

Step 2: Solve for v

Distribute negative:                    -3v + 1 + 7 - 6v - 6 = -37Combine like terms:                   -9v + 2 = -37Isolate v term:                             -9v = -39Isolate v:                                      v = 13/3

a number is 2/3 of another number. if the sum of the two numbers is 30, find the smaller number.

According to the problem:

and

From the second equation we get:

∴

Replacing the value of

in the first equation we get:

Answer:

1.5sin4x

Step-by-step explanation:

I just answered this question and got it right.

The function is 1.5sin(4x).

What is sin function?

The ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle is the sine function in trigonometry. A right triangle's sides or unknown angles can be found using the sine function.

Given the sine function from (0, 2π), and amplitude is 1.5, the period is π/2

sine function in general form

y = a sin (b (x – h)) + d

where a = amplitude, b= period

h is the phase shift, and

d is the vertical displacement.

according to question, This function currently has no phase shift, since

h = 0, and  no vertical displacement, since d = 0

equation is  y = a sin b x

and b is ratio of normal period to desired period

b = 2π/(π/2)

b = 4

substitute the value of a and b in equation we get,

y = 1.5 sin (4x)

Hence the sin function from 0 to 2pi is y = 1.5 sin (4x).

The regression equation for change in temperature, y, to amount of rain, r, is given by ŷ = 0.2 − 1.4r. On Monday, the observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees. Find and interpret the residual.

−1.94. The regression line overpredicts the temperature change.
−3.02. The regression line underpredicts the temperature change.

Answers

Given:

The regression equation for change in temperature, y, to amount of rain, r, is given by

[tex]\hat{y}=0.2-1.4r[/tex]

The observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees.

To find:

The residual and interpret it.

Solution:

According to the question, the observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees.

So, the actual value is 2.3 degrees.

Put r=0.4 in the given equation, to find the predicted value.

[tex]\hat{y}=0.2-1.4(0.4)[/tex]

[tex]\hat{y}=0.2-0.56[/tex]

[tex]\hat{y}=-0.36[/tex]

We know that,

Residual = Actual value - Predicted value

[tex]Residual=2.3-(-0.36)[/tex]

[tex]Residual=2.3+0.36[/tex]

[tex]Residual=2.66[/tex]

Residual is positive because predicated value is less than the actual value.

So, the regression line underpredicts the temperature change.

Therefore, the correct option is B.

What is the product of two fractions?

The product of two fractions is the product of the numerators and the product of the denominators.

Product of two fractions = Product of their denominators / Product of their numerators.

Twenty hundredths = 20/100

Sixty-five thousandths = 65/1000

Product = 20/100 × 65/1000

= 2/10 × 65/1000

= 130/10000

= 13/1000

= 0.013

Therefore, the product of twenty hundredths and sixty-five thousandths is 0.013.
