Suppose SAT Writing scores are normally distributed with a mean of 488488 and a standard deviation of 111111. A university plans
makvit [3.9K]

Answer:

The minimum score required for the scholarship is 644.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 488, \sigma = 111

What is the minimum score required for the scholarship?

Top 8%, which means that the minimum score is the 100-8 = 92th percentile, which is X when Z has a pvalue of 0.92. So it is X when Z = 1.405.

Z = \frac{X - \mu}{\sigma}

1.405 = \frac{X - 488}{111}

X - 488 = 1.405*111

X = 644

The minimum score required for the scholarship is 644.

If the average of three numbers is V if one number is Z and another is y what is the remaining number ?
user100 [1]
The formula for an average of three numbers is (x+y+z)/3.  So if V equals the average, then we find the formula
V = (x+y+z)/3
We are now looking for x.  We can divide each of the variables in the parentheses by 3, making the formula
V = x/3 + y/3 + z/3
So now bring the unwanted variables to the same side as V.
V - y/3 - z/3 = x/3
Now multiply both sides by 3 to find x.
3V - y - z = x

x = 3V - y - z

HELP ME PLEASE IF YOU SEE THIS PLEASE HELP I ONLY NEED THE ANSWER YOU DONT EVEN HAVE TO EXPLAIN IT
likoan [24]

Answer:

653

Step-by-step explanation:

The surface area of the larger cube is

2(10 x 7) + 2(12x7) + 2(10x12) = 140 + 168 + 240 = 548

The surface area of the smaller cube (minus the surface that is covered by the other figure)

4(8x3) + 1(3x3) = 96 + 9 = 105

105 + 548 = 653
