Answer:
b 129%
Step-by-step explanation:
Answer:
Step-by-step explanation:
x^2+120=0 can be rewritten as x^2 = - 120. Taking the square root of both sides, we get x = plus or minus i*√120 = plus or minus i*√4√30, or
x = plus or minus i*2√30
So the correct answer choice here is "None of the above."
N = 22b+34
Plug in.
n = 22(2)+34=44+34=78
n = 22(3)+34=66+34=100
n = 22(5)+34=110+34=144
n = 22(7)+34=154+34=189
Using the normal distribution, it is found that a student has to score 1.08 standard deviations above the mean to be publicly recognized.
<h3>Normal Probability Distribution</h3>
In a normal distribution with mean standard deviation z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
The top 14% of the scores are given by scores above the 86th percentile, which corresponds to Z = 1.08, hence, a student has to score 1.08 standard deviations above the mean to be publicly recognized.
