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.
He has already earned $8 5 times, so we know that he has 8×5=$40. 88-40=48, so he needs $48 more. 48÷8=6, so he needs to walk the neighbour's dog 6 more times to earn that extra $48
Answer: 6
Step-by-step explanation:
Slope is found by doing:
(x1 and y1 must be from the same ordered pair and x and y must be from the same ordered pair, however point (x1,y1) and (x,y) can be used interchangeably)
Let us say that (x1,y1) is (3,18)
And (x,y) is (5,30)
Okay so I am going to summarize the work out process because its a lot to
Here we go
1/3 (t) + 3/4 - 2/4 - t = ?
1/2 (simplify )
(1/3 (T)+3/4 - 1/2 - (t) = ?
t (2) / 2
1 - 2(t) / 2 = ?
3/4 (simplify this )
1/3(t)+ 3/4 - [1 - 2(t) / 2 = ?
1/3 (this is re last one you have to simplify)
L (Denominator): 3
R (Denominator): 4
L: [L.C.M] : 4
R: [L.C.M] : 3
Basically , we just switched the dominators around
So, Therefore The of t is -3/16
T = -3/16
