Answer:

y = -4x + 2

Step-by-step explanation:

for the first missing value we have to find the slope, the slope can be used by finding "rise over run". so the line goes down 4 units and 1 unit to the right, so then the slope would be -4 (the first missing value) and then the next missing number is the y-intercept. it's 2, because that's when x=0 and the line intersects the y-axis

In testing the hypotheses H 0 colon space mu space equals space 800 space v s. space H 1 colon space mu not equal to space 800,

steposvetlana [31]

Answer:

The p-value is 0.0802.

Step-by-step explanation:

The hypothesis for a test is defined as:

H₀: μ = 800 vs. Hₐ: μ ≠ 800

A two tailed test for the population mean can be performed using a z-test or a t-test.

A z-test is used if the data provided has information related to the population standard deviation and the sample size is large, i.e. n > 30.

And if the population standard deviation is not known and the sample size is small, then the t-test will be used.

Since there is no information about either the population standard deviation or the sample size, assume that z-test is used.

The test statistic value is:

z = 1.75

Compute the p-value of the test as follows:

$p-value=2\times P(Z>z)\\$

$=2\times (1-0.9599)\\=2\times 0.0401\\=0.0802$

*Use a z-table for the probability.

Thus, the p-value is 0.0802.

stacey made 8 necklaces in 48 minutes. nick made 4 necklaces in 24 minutes. is the rate at which they made necklaces equivalent.

Bingel [31]

Answer:

Yes.

Step-by-step explanation:

Divide - 48 / 8 which equals 6. Stacey makes 6 necklaces in 1 minute. Then, do 24 / 4. This also equals 6. Nick makes 6 necklaces in one minute. Therefore, their speed is equivalent.

Hey there! :)

Answer:

a. 3

b. -22

c. -2

d. -2

e. 5a + 8

f. a² + 6a + 3

Step-by-step explanation:

Calculate the answers by substituting the values inside of the parenthesis for 'x':

a. f(1) = 5(1) - 2 = 3

b. f(-4) = 5(-4) - 2 = -22

c. g(-3) = (-3)² + 2(-3) - 5 = 9 - 6 - 5 = -2

d. g(1) = 1² + 2(1) - 5 = 1 + 2 -5 = -2

e. f(a+ 2) = 5(a+2) - 2 = 5a + 10 - 2 = 5a + 8

f. g(a + 2) = (a + 2)² + 2(a + 2) - 5 = a² + 4a + 4 + 2a + 4 - 5 =

a² + 6a + 3
