Answer:

Step-by-step explanation:

The total amount paid by a member according to this table is

Total Amount Paid = fee + monthly fee(# of months)

Since the fee is the same regardless of how many months one signs up for, it should come out the same for each row in our table.

Row 1:

TAP = fee + 15(#months)

135 = fee + 15(4) and

135 = fee + 60 so

fee = $75

Row 2:

165 = fee + 15(6) and

165 = fee + 90 so

fee = $75

Row 3:

255 = fee + 15(12) and

255 = fee + 180 so

fee = $75

Apparently, the fee is $75.

Find an equation of the line. Write the equation using function notation.
Gemiola [76]

The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:

y = -4x+9

Step-by-step explanation:

Given equation of line is:

4y=x-8

We have to convert the given line in slope-intercept form to find the slope of the line

So,

Dividing both sides by 4

\frac{4y}{4} =\frac{x-8}{4}\\y = \frac{1}{4}x-\frac{8}{4}\\y = \frac{1}{4}x-2

Let m1 be the slope of given line

Then

m_1 = \frac{1}{4}\\

Let m2 be the slope of line perpendicular to given line

As we know that produt of slopes of two perpendicular lines is -1

m_1.m_2 = -1\\\frac{1}{4} . m_2 = -1\\m_2 = -1*4\\m_2 = -4

The slope intercept form of line is given by:

y = m_2x+b

Putting the value of slope

y = -4x+b

to find the value of b, putting (3,-3) in equation

-3 = (-4)(3) + b\\-3 = -12 +b\\b = -3+12\\b = 9

Putting the value of b in the equation

y = -4x+9

Hence,

The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:

y = -4x+9

Suppose a university advertises that its average class size is 34 or less. A student organization is concerned that budget cuts
Korolek [52]

Answer:

H0​: μ ≤ 34

H1​: μ > 34

The​ z-test statistic is ≈ 1.8

The critical​ z-score is 1.28

we fail to reject the null hypothesis H0​: μ ≤ 34

Step-by-step explanation:

H0​: μ ≤ 34

H1​: μ > 34

The​ z-test statistic is calculated using the formula:

z=\frac{X-M}{s} where

  • X is the average class size found in the sample (35.6)
  • M is the mean according to the null hypothesis (34)
  • s is the standard deviation for class size (9)

then z= \frac{35.6-34}{9} ≈ 0.18

The critical​ z-score is 1.28 for α=0.10​ (one tailed)

Because the test statistic is less than the critical value, do not reject the null hypothesis.
