How to tax things:
In this case, lets say the state tax is 7%.
Shen you buy something, lets say some shoes. For example lets say the price is 60.99
With the 7% tax, move the decimal point two times to the left: 7 -> .07
Multiply .07 by the total price
60.99 * .07 = 4.27
Then add this amount to the total price
60.99 + 4.27 = 65.26
This is how you tax
Answer:
C.There are 6.8 kiloliters in 68 hectoliters.
Step-by-step explanation:
1 hectolitre = 100 litres
1 decilitre = 0.1 litre
1 kilolitre = 1000 litree
6.8 kilolitres = 6800 litres
Or 68 hectolitres
Answer:
The z-score for this kernel is -2.3
Step-by-step explanation:
* Lets revise how to find the z-score
- The rule the z-score is z = (x - μ)/σ , where
# x is the score
# μ is the mean
# σ is the standard deviation
* Lets solve the problem
- The popping-times of the kernels in a certain brand of microwave
popcorn are normally distributed
- The mean is 150 seconds
- The standard deviation is 10 seconds
- The first kernel pops is 127 seconds
- We want to find the z-score for this kernel
∵ z-score = (x - μ)/σ
∵ x = 127
∵ μ = 150
∵ σ = 10
∴ z-score = (127 - 150)/10 = -23/10 = -2.3
* The z-score for this kernel is -2.3

Answer:
Choice D
Step-by-step explanation:
38/4 =9.5
Therefore, this number is between 9 and 10
Note:
38/4 = 9 remainder 2
Hence, the quotient is 9 which is a whole number
