Answer:
B. Correct decision
Step-by-step explanation:
We know that the average math SAT score of students at the school has changed from the 1991 mean of 465. That is μ≠465.
This hypothesis was tested and the null hypothesis, that states that the average math SAT score of students at the school has not changed from the 1991 mean, was rejected.
Then, the conclusion of rejecting the null hypothesis is right, as μ=465 is false.
Answer:
120
Step-by-step explanation:
Because you would just multiply the 2 numbers which would get you the area.
Answer:
y = 
x + 4
Step-by-step explanation:
We are to find the equation of line 1 which passes through point (-4,6)
Line 1 is perpendicular to line 2.
The equation of line 2 is; y = 
x + 5
The slope of line 2 is
Because the product of two perpendicular line is -1;
The slope of line 1 is -1 ÷ = 
Taking another point (x,y) on line 1;
Slope = change in y ÷ change in x
= 
y - 6 = (x + 4)
y - 6 = x - 
y = - + 6
y = x + 4
Answer: step 2, instead of adding the exponets together they should have done 5^3 first and then done the result of that (125) ^2
It’s 3y not just 3. You need to add the exponent as well
