Suppose GRE Verbal scores are normally distributed with a mean of 461 and a standard deviation of 118. A university plans to rec
nirvana33 [79]

Answer:

The minimum score required for recruitment is 668.

Step-by-step explanation:

Problems of normally distributed samples can be 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 = 461 \sigma = 118

Top 4%

A university plans to recruit students whose scores are in the top 4%. What is the minimum score required for recruitment?

Value of X when Z has a pvalue of 1-0.04 = 0.96. So it is X when Z = 1.75.

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

1.75 = \frac{X - 461}{118}

X - 461 = 1.75*118

X = 667.5

Rounded to the nearest whole number, 668

The minimum score required for recruitment is 668.

The graph shows the increase of the temperature over time in an oven what is the change in the y value and x value on the graph
Hatshy [7]

Let

x-------> the time in minutes

y-------> the temperature in Fahrenheit  degrees

A(2,150)\\B(3,190)

we know that

<u>the change in the y-values between two points is equal to</u>

(y2-y1)

Substitute the y-values of the point A and B in the formula

y2=190\\y1=150

(190-150)=40

<u>the change in the x-values between two points is equal to</u>

(x2-x1)

Substitute the x-values of the point A and B in the formula

x2=3\\x1=2

(3-2)=1

therefore

<u>the answer is</u>

The change in the y-value is 40 and the change in the x-value is 1

Beau has decided to use the method of elimination to solve the system of equations as shown below.
emmainna [20.7K]

Answer:

Step-by-step explanation:

The given equations are:

2x+3y=15                     (1)

and x-3y=3                 (2)

Now, simply adding equation (1) and equation (2), we get

2x+3y+x-3y=15+3

3x=18

x=6

Now, substituting the value of x=6 in equation (2). we get

6-3y=3

6-3=3y

3=3y

y=1

Thus, the values of x and y are 6 and 1 respectively.

In order to solve the system of solution, beau can see that in both  the given equations, coefficient of y is same and is with opposite sign, thus simply adding both the equations will eliminate y and she will get the value of x and then substituting the value of x in any of the equations, she can get the value of y. With this, she can get closer to the solution.
