The answer is go get a life
20, because 5 there and five back then 1 and 1 back and four and four back if not then just add all 5+4+1=10
Answer:
70.06
Mean score = 70
Step-by-step explanation:
16% of students scored higher than 80 on a recent normally distributed exam the standard deviation is 10 what is the mean
For a normal distribution :
Zscore = (x - mean) / standard deviation
x = score
P(Z > 80) = 16% = 0.16 ; corresponding Zscore = 0.994 (Z probability calculator)
Therefore ;
0.994 = (80 - mean) / 10
0.994 * 10 = 80 - mean
9.94 = 80 - mean
Mean = 80 - 9.94
Mean = 70.06
Hence, the mean score = 70.06 = 70
Answer: 
Step-by-step explanation:
To solve the exercise you must apply the following proccedure:
- Apply the distributive property.
- Keepn on mind that when you multiply two powers with equal base, you must add the exponents.
- Add like terms.
Then:
2^3 = 8
3^2 = 9
8 * 9 * 5 = 360
15 is a factor of 360, so the answer would be <span>1. Fifteen is a factor of the number because both 3 and 5 are prime factors</span>
