Standard deviation is simply the square root of the variance.
We need to get the square root of each variance to see whether its standard deviation is greater than its variance.
A. 0.25 ⇒ √0.25 = 0.50
B. 1.75 ⇒ √1.75 = 1.32
C. 2.5 ⇒ √2.5 = 1.58
D. 1.5 ⇒ √1.5 = 1.22
Among the choices, only A. 0.25 has a standard deviation that is greater than the variance. The standard deviation is 0.50
Answer:
a. $5.43
b. $141.25
c. $8.75
Step-by-step explanation:
First you find the total amount you it cost for all the items
$135.82 + 4% = $141.25
You give three $50 dollar bills
50 * 3 = 150
$150 is the amount you give
--------------------------------------
141.25 - 135.82 = 5.43
$5.43 is the amount of the sale price
---------------------------------------
To find the amount is cost for all the items you add the sales tax + the original price
$135.82 + 4% = $141.25
$141.25 is the amount including the tax
---------------------------------------
Subtract
150 - 141.25 = 8.75
So you will get $8.75 back
In short, a horizontal translation, means f("x + some number"),
now, that number is 2, and is to the left, so that means f(x + 2)
Answer:
-5c^3
Step-by-step explanation:
There are 3 -5's and 3 c's. Because we are multiplying the c's by the product of the fives it is. -5c to the power of 3
