A random sample of 10 subjects have weights with a standard deviation of 11.0995 kg. What is the variance of their weights?

goblinko [34]

Answer:

$123.19890025 kg^2$

Step-by-step explanation:

We are given that

Standard deviation, s=11.0995 kg

Sample size, n=10

We have to find the variance of their weights.

We know that

Variance= $(standard\;deviation)^2$

Using the formula

The variance of their weights

= $(11.0995)^2$

= $123.19890025 kg^2$

Hence, the variance of their weights= $123.19890025 kg^2$

Tanner is ordering a pizza at a restaurant. The cost of a cheese pizza is $8.69, and then it costs $0.30 for each additional top

Grace [21]

Answer:

Option A. $c=8.69+0.30t$

Step-by-step explanation:

Let

t ------> the number of additional toppings

c ----> the cost of the pizza in dollars

we know that

The linear equation that represent this situation is

$c=0.30t+8.69$

This is the equation of the line in slope intercept form

where

the slope m is equal to

$m=0.30\frac{\$}{topping}$

the y-intercept b is equal to

$b=\$8.69$ -----> the cost of a pizza without topping
