Answer:
percentage increase in Kristen's average score is = 25%
Step-by-step explanation:
Given:-
- The last year score, Si = 84 points
- This year score, Sf = 105 points
Find:-
What is the percent of increase in Kristen's average score?
Solution:-
- We are to determine the percentage increase in Kristen's average score from last year.
- The relation to develop percentage increase "%inc" is given by:
%
- plug in the values:
- The percentage increase in Kristen's average score is = 25%
Let's assume we were given 2 numbers: 15 and 30. Their sum is:
We want to express it as the product of GCF and another sum.
15 is divisible by: 1, 3, 5, 15
30 is divisible by: 1, 2, 3, 5, 6, 10, 15, 30
The greatest number that appears in 2 series is 15.
In this case sum of two numbers can always be written as:
<span>The value of z is 0.8770. This answer was derived from information in the question, which states that the value of z is 0.8770. Granted, I don't understand what is meant by "cumulative standardized normal distribution." I only passed statistics because the professor felt sorry for me.</span>
This answer would be 21 because you’d just do 15 increased by 40% which gave me 21
