Raw scores on a certain standardized test one year were normally distributed, with a mean of 156 and a standard deviation of 23.
s344n2d4d5 [400]

Answer:

About 220 of the students scored less than 96

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Mean of 156 and a standard deviation of 23.

This means that \mu = 156, \sigma = 23

Proportion that scored less than 96:

p-value of Z when X = 96. So

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

Z = \frac{96 - 156}{23}

Z = -2.61

Z = -2.61 has a p-value of 0.00453.

About how many of the students scored less than 96?

0.00453 out of 48592.

0.00453*48592 = 220.1.

Rounding to the closest integer:

About 220 of the students scored less than 96

Mr. shaw graphs the function f(x) = –5x 2 for his class. the line contains the point (-2, 12). what is the point-slope form of t
True [87]

y - 12 = -5(x + 12) is the required equation.

f(x) = -5x + 2

let f(x) = y

y = -5x + 2

y = -5x + 2

comparing it to y = mx + c

m = -5

The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point. The equation of a line is an equation that is satisfied by each and every point on the line. This means that a linear equation in two variables represents a line.

The point slope equation formula is

y - y₁ = m(x - x₁)

Now the equation of line containing (-2,12) is

y - {y}_1= m(x - {x}_1)\\

y - 12 = -5(x + 12)

the area of a kite is 384 square feet. one diagonal is three times as long as the other diagonal. find the length of each diagon
lys-0071 [83]
The lengths of the diagonals are 16 and 48 feet.

To find the area of a kite, you multiply the lengths of the diagonals by each other and divide by 2. All we need to do is fill in the information in the formula and solve for the missing side.

A = pq/2

384 = (x(3x))/2
768 = 3x^2
256 = x^2
16 = x

Now, just multiply this diagonal of 16 by 3 to find the other diagonal of 48.

How to find the the angle measurement ?
Sindrei [870]
That is a 180 degree angle (the straight line) and one angle is 78, so you subtract 78 from 180
So the angle would be 102 degrees
