Answer:$630
Step-by-step explanation:
What is 80% of 350?
Y is 80% of 350
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 80% * 350
Converting percent to decimal:
p = 80%/100 = 0.8
Y = 0.8 * 350
Y = 280
then u add 280 to 350
Answer:
The answer is 314cm²
the formula for the sphere area of a sphere is:
A= 4TT²
A = 4x3.14x5²
first solve for exponents
A = 4x 3.14x25
then multiply
A = 314cm²
Answer:
The percentage of people taking the test who score between 391 and 767 is 95%.
Step-by-step explanation:
The Empirical Rule(68-95-99.7 Rule) states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 579
Standard deviation = 94
391 = 579 - 2*94
So 391 is two standard deviations below the mean.
767 = 579 + 2*94
So 767 is two standard deviations above the mean.
By the Empirical Rule:
The percentage of people taking the test who score between 391 and 767 is 95%.
