Answer:
9.06
Step-by-step explanation:
1. Add up all data values to get the sum:
-8 + 12 + 25.9 + -6.3 + 21.9 = 45.5
2. Count the number of values in your data set:
5
3. Divide the sum by the count:
45.4/5 = 9.06
4. You can round to 9.1
Answer:
8.46
Step-by-step explanation:
The amount of money each one will make at the end of the day is equals to $21.775.
As per given in the question,
Amount of money earned earned by two friends per hour = $6.50
Total hours spent for baby sitting each day = 6.7hours
Total amount earned by both the friends per day = 6.50 × 6.7
= $ 43.55
Amount of money earned by each one = 43.55 ÷ 2
=$ 21.775
Therefore, the amount of money each one will make at the end of the day is equals to $21.775.

Answer:
-5 + 3(7.2 - 3.2) equals 7.
Step-by-step explanation:
The order of operations states the order in which different mathematical operations should be done first, you can use the mnemonic PEMDAS to remember the order to complete each operation. PEMDAS states that the order must be followed as Parenthesis, Exponents, Multiplication/Division, and Addition/Subtraction. In the expression -5 + 3(7.2 - 3.2), the three mathematical operations being used are subtraction, multiplication, and parenthesis, so based on PEMDAS, the order to complete them is parenthesis, multiplication, and subtraction. -5 + 3(7.2 - 3.2) = -5 + 3(4) = -5 + 12 = 7, so that is your final answer.
Answer:
381 cubic inches
Step-by-step explanation:
To find the volume of the cube, use the volume formula for a rectangular prism V = l*w*h and for a triangular prism V = 1/2 l*w*h.
<u>Rectangular prism</u>
Substitute l = 16, w = 7, and h = 3.
V = 16*7*3 = 336 cubic inches
<u>Triangular prism</u>
Substitute l = 5, w = 3 and h = 6.
V = 1/2*5*3*6 = 45 cubic inches
Together the volume will be 336 + 45 = 381.
