Answer:
H₀: µ ≤ $8,500; H₁: µ > $8,500
z= +1.645
Step-by-step explanation:
From the given problem As average cost of tuition and room and board at a small private liberal is less than the financial administrator As hypothesis is true.
As standard deviation is $ 1,200
α = 0.05
H₀: µ ≤ $8,500
if the null hypothesis is true then value for critical z is +1.645.
The number would be 21 because if you add 5+37 then divide by 2.Younwill get the answer
Hello!
So let's first start out by solving the left side of the equation:
2 to the third power is 8
The right side now: -3 to the second power is -9
In total: 8- (-9)
So your answer is C) -1
I hope it helps!
Hope this helps you out 3w+7=8
The answer is w= 1/3
Step by step:
3w+7=8
Step 1: is subtract is 7 from both sides.
3w+7-7=8-7
3w=1
Step 2: Divide both sides by 3.
3w/3 = 1/3
Your solution is:
w=1/3
Answer:
Rocco doesn't have enough money to buy the golf irons
Step-by-step explanation:
step 1
Find the rest of the money left in the savings account
