Answer:
probability that their average salary is more than $77,500 is 0.1587
Step-by-step explanation:
standard error
= 10,000/sqrt(16)
=10,000/4
= 2500
(77,500 - 75000)/2500
2,500/2500
= 1
p (z > 1) = .1587
So, the probability that their average salary is more than $77,500 is 0.1587
First account: $6500
Second account: $8500
Set x is amount of money in first account
=> x + 2000 is money in second account.
X*3% + (x+2000)*4% = 535
=> x = (53500 - 8000) / 7
X = 45500 / 7 = 6500
=> account #1 = x = 6500
Acc #2 = x + 2000 = 6500 + 2000 = 8500
Answer:
a control group is not used
1 bushel = 186 heads of lettuces
multiply each side by 6
6 bushels = 1,116 heads of lettuces
The farmer picked 1,116 heads of lettuces
900,000 would be the nearest hundred thousand
sorry if it's wrong, but I did try
