<span>D = 4 - 4*9*(-7) = 4 + 252 = 256 = 16*16
x1 = (-2 + 16)/9 = 14/ 9
x2 = (-2 - 16) / 9 = -2

Answer:
y = - 36x - 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 36 and c = - 9 , then
y = - 36x - 9 ← equation of line

Answer:
There is sufficient evidence to support the claim that the mean temperature is different from 45 degrees
Step-by-step explanation:
Given : Claim : The mean temperature of the refrigerators is different from 45 degrees
To Find :Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms.
Solution:
Claim : The mean temperature of the refrigerators is different from 45 degrees
So, Null hypothesis :
Alternate hypothesis :
We are given that the conclusion is to reject the null hypothesis.
So, we can say that the claim is true that mean temperature is different from 45 degrees.
There is sufficient evidence to support the claim that the mean temperature is different from 45 degrees
Answer:
Step-by-step explanation:
The table tells you that Marci's monthly payment on a 2-year loan at 8.5% will be $45.46 on each $1000 borrowed. For her $5000 loan, her monthly payment will be 5 times the table value, or ...
monthly payment = $5000/$1000 × $45.46
monthly payment = $227.30
__
Her total of 24 payments will be ...
total repaid = 24 × $227.30 = $5,445.20
That amount is $445.20 more than the amount borrowed, so that is Marci's finance charge.
__
Marci's monthly payment will be $227.30, and her total finance charge will be $455.20.
