Answer:

The width is 36.4 inches

Step-by-step explanation:

we know that

Applying teh Pythagorean Theorem

D^2=h^2+W^2

where

D is the length of the diagonal of the television

W is the width

h is the height

substitute the given values

42^2=21^2+W^2

solve for W

W^2=42^2-21^2\\W^2=1,323\\W=36.4\ in

What is the perimeter of semicircle with radius 3cm
lora16 [44]
6+ 9.43 = 15.43

3 is the radius so the diameter is 6.

d • pi is the equation for circumference.
6 • pi is approximately 18.85

and because its a semi circle, you divide that by half and get 9.43

then add the diameter and half the circumference which = about 15.43 and thats the perimeter.

Find the following list of data calculate a demean be the maid and see mode or mothers for the following numbers listed in the p
Sholpan [36]

Answer:

Mean = 4.8875

Median = 4.6

Mode = 4.5 and 7.7

Step-by-step explanation:

Mean is the sum of total of data divided by the sample size

Sum total = 1.5 + 4.7 + 6 + 7.7 + 7.7 + 4.5 + 2.5 + 4.5

Sum total = 39.1

Sample size = 8

Mean = 39.1/8

Mean = 4.8875

To get the median we need to first rearrange

1.5, 2.5, 4.5, 4.5, 4.7, 6, 7.7, 7.7

Median = 4.5 + 4.7/2

Median = 4.6

Hence the median is 4.6

Mode is the value occuring the most. Since 4.5 and 7.7 both occurs twice, hence the mode of the data is 4.5 and 7.7
