Standard form: 100,000,000 (100 million)
Scientific form: 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
Perimeter is equal to 2l+2w, or 2 times the length plus 2 times the width.
So to solve for this you'd take 2(6.5) + 2(4.23).
2(6.5)= 13
2(4.23)= 8.46
13+8.46= 21.46 meters.
Based on this, the answer is C.
