Anwser: The hotels charge for a call is the same for a 20 minute call.
Step-by-step explanation:
Alrighty, same deal as the last problem, set up a equality, it should look like this:
$1+.80x=$2+.75x
Move the variable to the left of the equation:
.80x-.75x=2-1
Simplify
.05x=1
x=20
54,273 = A * 1.70^6 where A is the initial number
A = 54273/1.70^6 = 2248
Answer:
a. proportions have not changed significantly
Step-by-step explanation:
Given
Business College= 35 %
Arts College= 35 %
Education College = 30%
Calculated
Business College = 90/300= 9/30= 0.3 or 30%
Arts College= 120/300= 12/30= 2/5= 0.4 or 40%
Education College= 90/300= 9/30 = 0.3 or 30%
First we find the mean and variance of the three colleges using the formulas :
Mean = np
Standard Deviation= s=
Business College
Mean = np =300*0.3= 90
Standard Deviation= s= == 7.94
Arts College
Mean = np =300*0.4= 120
Standard Deviation= s= == 8.49
Education College
Mean = np =300*0.3= 90
Standard Deviation= s= == 7.94
Now calculating the previous means with the same number of students
Business College
Mean = np =300*0.35= 105
Arts College
Mean = np =300*0.35= 105
Education College:
Mean = np =300*0.3= 90
Now formulate the null and alternative hypothesis
Business College
90≤ Mean≥105
Arts College
105 ≤ Mean≥ 120
Education College
U0 : mean= 90 U1: mean ≠ 90
From these we conclude that the proportions have not changed significantly meaning that it falls outside the critical region.

Step-by-step explanation:
The computation of the number of pencils she bought is shown below:
It could be
6 × 2 boxes = 12
6 × 3 boxes = 18
6 × 4 boxes = 24
6 × 5 boxes = 30
6 × 6 boxes = 36
And so on
Answer:1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250
