Answer:
A) 34.13%
B) 15.87%
C) 95.44%
D) 97.72%
E) 49.87%
F) 0.13%
Step-by-step explanation:
To find the percent of scores that are between 90 and 100, we need to standardize 90 and 100 using the following equation:
Where m is the mean and s is the standard deviation. Then, 90 and 100 are equal to:
So, the percent of scores that are between 90 and 100 can be calculated using the normal standard table as:
P( 90 < x < 100) = P(-1 < z < 0) = P(z < 0) - P(z < -1)
= 0.5 - 0.1587 = 0.3413
It means that the PERCENT of scores that are between 90 and 100 is 34.13%
At the same way, we can calculated the percentages of B, C, D, E and F as:
B) Over 110
C) Between 80 and 120
D) less than 80
E) Between 70 and 100
F) More than 130
Answer:
Anne
Step-by-step explanation:
The expression cannot be simplified anymore, but it can be laid out correctly.
The greatest number for the exponents should come first, so Anne is the one who laid it out correctly.
Hope it helps!!

Answer:
0
Step-by-step explanation:
The slope of a horizontal line is zero (0). For any finite "run", the "rise" is zero.
slope = rise/run = 0/run = 0
Answer:
Step-by-step explanation:
The formula for the surface area is A = 4πr². This formula can be solved for r² and then the result solved for the radius, r:
A
r² = -------- The radius of the sphere is as follows:
4π
√(30 m²)
-------------- meters
2√π
