Answer:
23
Step-by-step explanation:
4r-10=18
4r=28
4r/4=28/4
r=7
2(7)+9=23
Part A
For Todd's class, we have this given info:
- mu = 70.6 = population mean of math scores
- sigma = 11.9 = population standard deviation of math scores
Compute the z score for x = 74.6
z = (x-mu)/sigma
z = (74.6 - 70.6)/(11.9)
z = 0.34 approximately
Side note: Convention usually has z scores rounded to two decimal places. If your teacher instructs otherwise, then go with those instructions of course.
<h3>Answer: 0.34</h3>
======================================================
Part B
For Garret's English class, we have:
Compute the z score for x = 68.8
z = (x-mu)/sigma
z = (68.8 - 63.7)/(8.6)
z = 0.59 approximately
<h3>Answer: 0.59</h3>
======================================================
Part C
Garret has the higher z score, which means that Garret did relatively better to his classmates compared to Todd's performance (in relation to his classmates). The z score is the distance, in units of standard deviation, the score is from the mean. Positive z values are above the mean, while negative z values are below the mean.
<h3>Answer: Garret did relatively better</h3>
I think this is going to help you understand the concept and hope that the answer is correct. Thanks for understanding.
Answer:
The sum of two angles = 90
1 x + 2 x =90
3 x = 90
x =90/3 = 30
so x = 30 it is one angle
another angle = 2 x
= 2 *30 = 60 its larger angle
ans = 60
Step-by-step explanation:
0 and 1 are integers, there are no other integers between them
