Answer: 11
Step-by-step explanation:
The sum of 8 and 3
Sum is the same as addition.
Therefore, the equation is 8+3
Solve 8+3
8+3=11
Answer: Try using calculatorsoup dot com, you need to be more specific, and use Find A, C and r | Given d?
radius r = 7.5 in
diameter d = 15 in
circumference C = 47.123889803847 in
area A = 176.71458676443 in2
In Terms of Pi π
circumference C = 15 π in
area A = 56.25 π in2

Answer: In step 1, Andrew used the commutative property
Explanation:
In step 1 he used commutative, which is a + b = b + a
(- 5.7 + 2.2) = 2.2 + (- 5.7)
Step 2, he used associative property, not the distributive.
Step 3, he just added5.7 + 1.1 = 6.8
Step 4, he distributed the negative sign:
- (6.8) = - 6.8
Answer: First, add 3.99 + 7.17. Then take the sum of those two numbers and multiply it by .05 to get 0.55. Since we are dealing money, round to the nearest hundredth to get .56. Add the sum of 3.99 and 7.17 (11.16) and .55 to get a total of 11.71. Therefore the total cost of their dinner, including tax, was $11.71.

Answer:

Step-by-step explanation:
We have been given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -1.5.
To find Sally's temperature we will use z-score formula.
, where
= Mean,
= Standard deviation.
Let us substitute our given values in z-score formula.

Multiply 0.62 to both sides of equation.


Add 98.20 to both sides of equation.


Therefore, Sally's temperature will be 97.27 degrees Fahrenheit.
