Use employee identification numbers to randomly select 200 employees.

Step-by-step explanation:

In order to choose 200 random people for the survey, it shall be purely random and unbiased.

Can someone please help me it’s urgent

Evgen [1.6K]

Answer:

8.5 in

Step-by-step explanation:

You are solving for the hypotenuse right? So you would use this formula:

c = square root a^2+b^2

the c is the hypotenuse (long side of a right triangle) and a will be 4 and b will be 7.5. substitute the numbers in, solve, and you get 8.5 inches!

x = square root 4^2 + 7.5^2

x = square root 16 + 56.25

x = square root 72.25

x = 8.5 inches

Suppose a circle with center (14,9) passes through point (16, 12). Which equation represents the circle?

kifflom [539]

Answer:

( x - 14)^2 + ( y - 9)^2 = 13

Step-by-step explanation:

The equation of the circle with a center and a point

( x - a) ^2 + ( y - b) ^2 = r^2

( 14 , 9) - center-( a, b)

a = 14

b = 9

( 16 , 12) - point - ( x, y)

x = 16

y = 12

Step 1: substitute the center into the equation

( x - 14)^2 + ( y - 9)^2 = r^2

Step 2: substitute the point into the equation

( x - 14)^2 +( y - 9)^2 = r^2

( 16 - 14)^2 + ( 12 - 9)^2 = r^2

2^2 + 3^2 = r^2

4 + 9 = r^2

13 = r^2

Step 3: subs the radius into the equation

( x - 14)^2 + ( y - 9)^2 = r^2

( x - 14)^2 + (y - 9)^2 = 13

Therefore, the equation of the circle is

( x - 14)^2 + ( y - 9)^2 = 13

Tj's Cat Food is sold in boxes shaped like this. Each tin has an intemal height of 5 cm. The area of the lid of the tin is 35 sq

natali 33 [55]

Answer:

Volume, $V=175\ cm^3$

Step-by-step explanation:

We have,

Height of each tin is 5 cm

The area of the lid of the tin is 35 square centimeters.

It is required to find the volume of the cat food that the tin contains. Volume of the box is also given by the product of area and height such that,

$V=A\times h\\\\V=35\times 5\\\\V=175\ cm^3$

So, the volume of the cat food that the tin contains is $175\ cm^3$ .
