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

Answer:
the interest earned= 93.401
and the future value of an annuity= 493.401
Step-by-step explanation:
Given Data:
Interest rate= 7%
time,t = 3 years
weekly payment, P= 400
At the end of 3 years, final investment A= ?
n= 52 as it is weekly
As per the interest formula
A= P(1+r/n)^nt
Putting value in above equation
= 
= 493.401
Interest earned = A-P
= 493.401-400
= 93.401 !
Answer:
A
Step-by-step explanation:
I think that's the answer because
60 minutes = 1 hr
120 minutes = 2hrs
So the graph must be constant with the write amount of min/hr since the x axis is the number of mins and the y axis is the number of hours. (x,y)
(60,1)
(120,2)
Answer:
x=− 9
/4
or
=−2.250
