Answer:
Step-by-step explanation:
If A is in between Y and Z, then;
YA+AZ = YZ
Given.
YA = 14x,
AZ = 10x and
YZ = 12x + 48
Substitute into the formula
14x+10x = 12x+48
Find x;
24x = 12x+48
24x-12x = 48
12x = 48
x = 48/12
x = 4
Get AZ
AZ = 10x
AZ =10(4)
AZ = 40
Answer:
Step-by-step explanation:
Greek students will represent p1 (proportion 1)
Non-Greek students will represent p2
If we were to conduct a hypothesis test for this data, we would use a test for the difference of 2 proportions. The hypothesis for this test would be as follows...
H0: p1 - p2 = 0
Ha: p1 - p2 > 0
The reason the alternate hypothesis is greater than 0 is because the question claims that the proportion of greek students (p1) is greater than the proportion of non-greek students (p2). So p2 is smaller than p1. We are subtracting a smaller number from a larger number. That will always result in a positive number.
Answer:
2n= 53
and you divide both sides by 2
2n/2 =53/2
2 divided by 2 is 1 and 53 divided 2 is 26.5
n= 26.5
The first answer is correct, if you go back by 5% each year you will see that.
