8 = m/4

8(4) = m/4(4)
m = 8(4)
m = 32

m - 12 =
(32) - 12 =
20

Your answer is 20

Hope this helps

The scores on a standardized exam are normally distributed with a mean of 400 and a standard deviation of 50.
S_A_V [24]

Using the normal distribution, it is found that approximately 40% of the scores are greater than 413.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

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

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

In this problem, we have that the mean and the standard deviation of the scores are given by:

\mu = 400, \sigma = 50

Approximately 40% of the scores are greater than the 60th percentile, which is <u>X when Z = 0.253</u>.

Then:

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

0.253 = \frac{X - 400}{50}

X - 400 = 50(0.253)

X = 412.65.

Rounding up, approximately 40% of the scores are greater than 413.

Which linear function is represented by the graph?
maxonik [38]

Answer:

y=-\frac{1}{2}x+1

Step-by-step explanation:

To determine the linear function , pick two points from the given line

(0,1) (4,-1). find the slope using the points

slope = \frac{y_2-y_1}{x_2-x_1} =\frac{-1-1}{4-0} =\frac{-1}{2}

Equation of a line in point slope form is

y-y_1=m(x-x_1)

slope =-1/2, (0,1)

y-y_1=m(x-x_1)

y- (1)=-\frac{1}{2}(x-0)

y-1=-\frac{1}{2}x

Add 1 on both sides

y=-\frac{1}{2}x+1

A cone has a volume of 37.68cm3. If the height of the cone is 9cm what is the radius of the cone's
JulijaS [17]

Answer:

2cm

Step-by-step explanation:

Volume of a cone= \pi r^2\frac{h}{3}

Substitute: 37.68cm^3=\pi r^2(\frac{9}{3})

37.68cm^3=\pi r^2(3)

37.68cm^3=\pi r^2(3) Divide by 3

12.56cm=\pi r^2 Divide by pi

4cm=r^2

r=\sqrt{4}

r=2
