Answer:
The answer to your question is the second and the last choices.
Step-by-step explanation:
Process
1.- In the first step v₀t subtract d and the result is
d - v₀t = at²/2
2.- In the second step, 2 multiply (d - v₀t), and the result is
2(d - v₀t) = at²
3.- In the third step t² divide 2(d - v₀t), and the result is
a = [2(d - v₀t)]/t²
$230.63 : 123 / 8 is 15.375, (The unit rate) • 15 would be 230.625. Round up to 230.63.
Answer:
yes
Step-by-step explanation:
well im going to assume that the original equation is y = -3/2x - 2
if that is the case, then if you plug in the numbers
4 = -3/2(-4) - 2
4 = 6 - 2
4 = 4
so yes when x is -4, y is 4; (x, y) (-4, 4)
Answer:
Step-by-step explanation:
Given that the mean salary for a new teacher in your town is $48,000
You believe it is higher for new teachers in a neighboring town.
So to prove or disprove your claim you have to show statistical evidence.
For that hypothesis testing is necessary.
You must conduct a hypothesis test for comparing the mean of salary of new teacher with neighbouring places
The hypotheses wouldbe
where mu is the average for neighbouring states.
