Answer:
Given:
Null hypothesis: the average salary for new college graduates with a job is $50,556.
Alternative hypothesis: the graduates from a university earn more than that average.
Using the z-test:
=> Calculate the value of test statistic:
t = (mean of sample - mean of null hypothesis)/(std/sqrt(number of sample)
= (53200 - 50556)/(10200/sqrt(100))
= 2.592 > 1.645
=> Reject the null hypothesis, their graduates earn more than average
Hope this helps!

Answer:
$154,763.5
Step-by-step explanation:
A = P(1 + r/n)^nt
Where,
A = future value
P = present value
r = interest rate
n = number of periods
t = time (years)
P = 97,000
r = 6% = 0.06
n = 365
t = 8 years
A = P(1 + r/n)^nt
= 97,000(1 + 0.06/365)^365*8
= 97,000(1 + 0.00016)^2,920
= 97,000(1.00016)^2,920
= 97,000(1.5955)
= 154,763.5
A = $154,763.5
Answer:
#4: -18xy^3z * sqrt(z)
#5: 24xy^3 * sqrt 3(x^2)
Step-by-step explanation:
#4: -2*sqrt(9^2 * x^2 * y^2 * y^2 * y^2 * z^2 * z)
You can cancel if there is a number sqaured
-2 * 9 * x * y * y * y * z * sqrt(z)
-18xy^3z * sqrt(z)
#5: 6 * sqrt 3( 4^3 * x^3 * x^2 * (y^3)^3 )
You can cancel if the number is cubed.
6 * 4 * x * y^3 * sqrt 3( x^2 )
24xy^3 * sqrt 3(x^2)
