Answer:
A
Step-by-step explanation:
B,.C and D are wrong because
B states all. The hypothesis stated above does not mention all samples
.
C. Mentions a mean. Per the hypothesis, the percentage of defective screens was an actual number and not a mean.
D. The question is not referring to a standard deviation
The answer is
96%.
Explanation:
It is generally presumed that the scores are normally distributed.
1) You are given how many standard deviations from the mean Jeremy's score is. This is exactly the definition of the
z-score. Therefore z = 1.75
2) Look at a left-tail z-table in order to find the area of the normal curve on the left of your z-score (see picture attached). A = 0.9599
3) Multiply the area by 100 in order to find the
percentile:
<span>0.9599 </span>× 100 = 95.99
Therefore, 95.99% of the students scored less than Jeremy.
Hence, the answer is
96%.
C
a ratio of 5 : 5 simplifies to 1 : 1, which basically means we require the midpoint of the line segment
using the midpoint formula
M = [
(0 + 20 ),
(15 + 0)] = (10, 7.5 )
Answer:
I don't know just need points
Answer:
No, they are not scaled copy's.
Step-by-step explanation:
So we can flip figure F to where it is facing the direction that figure A is.
First we do 105 divided by 35, the corresponding sides, and get 3. If you do 96 divide by 19, you get 5.052631579. You are free to use my explanation word for word as your reason why.
