Answer:
(D)0.87
Step-by-step explanation:
<u>DEFINITION</u>
The mean of the sampling distribution of the sample proportion is equal to the population proportion.
Given that out of the random sample of 144, 87% said that it was delicious
Therefore, the Population proportion = 87%
The sample size of 144 from 5000 will have proportion which will follow a normal distribution with mean p = 87%
Hence the mean of the sampling distribution of is 0.87
It's 8x^2 + 18x -18
^2 means squared
Answer:
tommy is 6ft and makes a 4ft tall shadow
which means that the building would make a shorter shadow then its height.
48/4=12
12*6=72
72ft
Polynomial division yields
As
, you have the remainder term approaching
, so the horizontal asymptote is the line
.
These were the missing data:
They get a reduced rate if they rent 7 pairs of skis for every 3 snowboards rented the reduced ski rate is $45.50 per pair of skis per week, and the reduced snowboard rate is $110 per snowboard per week. the sales tax on each rental is 16%<span>The group has $2500 available to spend on ski and snowboard rentals. Why is the greatest number of pairs of skis and snowboards the group can rent if the ratio of pair of skis to snowboards is 7:3?
7 pairs of skis * 45.50 rent per pair = 318.50
3 snowboards * 110 rent per snowboard = 330
318.50 + 330 = 648.50
648.50 * 1.16 = 752.26
2500 / 752.26 = 3.32 or 3 sets of 7:3 ratio.
7 * 3 = 21
21 * 45.50 = 955.50
3 * 3 = 9
9 * 110 = 990
955.50 + 990 = 1,945.50
1,945.50 * 1.16 = 2,256.78 total cost
2,500 - 2,256.78 = 243.22 change
The group can rent 21 pairs of skis and 9 snowboards for only 2,256.78</span>
