Answer:
Step-by-step explanation:
Given that private colleges and universities rely on money contributed by individuals and corporations for their operating expenses
A recent survey of 8 private colleges in the United States revealed the following endowments (in millions of dollars)
Mean = 180.975 and std dev s = 143.042
Assuming a normal distribution we have 95% critical value is 1.96 and 99% critical value is 2.58
a) 95% Conf interval = Mean ±1.96* std error
=
Since sample size is very small confidence interval is wider.
b) 99% Conf interval = Mean ±2.58* std error
=
Since sample size is very small confidence interval is wider.
Answer:
You know you got one solution if when you solve your equation its not for example 5=5 because that's infinite solutions or 5=6 because that's no solution so one solution would be like y=5
Answer:
18 yards
Step-by-step explanation:
Rectangle area = Length (L) x Width (W)
63 yd^2 = L*W
63 yd^2 = L*(3.5 yd)
L = 18 yards
Answer:
True
Step-by-step explanation:
We have that,
The cone A has the length of the lateral side = h and the height of the cylinder B = h.
Since, the lateral surface areas are given by,
Lateral surface area of cone = 
, where l is the length of the lateral side.
So, we get 
= 
.
Also, Lateral surface area of cylinder is 
, where h is the height of the cylinder.
So, we get 
=
Thus, we see that, 
Hence, the given statement is correct.
Answer:
C) a = 10√3, b = 5√3, c = 15 , d = 5
Step-by-step explanation:
Here we use the ratio of 30, 60, 90 degree triangle.
The ratio of sides, 1:√3:2
2x = 10
x = 5
d = 5
b = 5√3
c = 5√3√3
c = 5*3 = 15
c = 15
a = 2(5√3)
a = 10√3
Therefore, a = 10√3, b = 5√3, c = 15 and d = 5
Thank you.
