3/4 of the shirts in a store are black. 50% of the shirts are white and the remaining 12 shirts are red. How many black masks ar

saul85 [17]

Answer:

There are total 96 shirts out of which 72 are black and 12 are white and 12 are red.

Step-by-step explanation:

Let the total number of shirts be x.

Then 3/4= 0.75 shirts are black

50% or 50/100 =0.5 of 1/4 ( 1-3/4) remaining are white

and 12 are red

x= 0.75x+0.125x+12

x= 0.875x+ 12

x-0.875x= 12

0.125x= 12

x= 12/0.125

x= 96

There are total 96 shirts out of which 3/4 are black

96*0.75= 72 are black and

96*0.25= 24 are left behind out of which 50% are white.

12 are white and 12 are red.

Find the population mean or sample mean as indicated. population: 44, 22, 1111, 1717, 2121

vlada-n [284]

The mean of the sample given by 44,22,11,17,21 will be given by:
$\mu= \frac{\Sigma x_i}{n}$
the sum of x's will be:
44+22+11+17+21
=115
n=5
therefore the mean will be:
μ=115/5
=23

In the coordinate plane, three vertices of rectangle HDK are H(0, 0), (0, d), and Kle, 0). What are the coordinates of point J?

Alik [6]

Answer:

K = (e, d)

Step-by-step explanation:

We are given the coordinates of three vertices of a rectangle and we are to find the coordinates of the fourth point J.

H (0, 0)

I (0, d)

K (e, 0)

J = ?

We can find this using the following formula:

K = H + (I - H) + (K - H)

K = H + I - H + K - H

K = I + K - H

Substituting the given values in it to get:

K = $(0, d) + (e, 0) - (0, 0)$

K = $(0+e-0, d+0-0)$

K = (e, d)
