To find a percentage of a number, multiply by the decimal form of that percentage(20%=0.20). So, take the cost, $430, and multiply by common state sales tax (7% for me)---430 x 0.07 = 30.10 The sale tax rate is 7%.
Answer:
40. 3+2x4-1=10
39. 3+2x4+1=12
38. (3+2)x4+1=21
37. 2+3x4-1=13
Step-by-step explanation:
The median would be a better measure of central tendency when the data is skewed (or if the frequency distribution for the data is skewed).
From what I see in the problem, the expression is
![(\frac{3^a^2}{3a^-1} )^k](https://tex.z-dn.net/?f=%28%5Cfrac%7B3%5Ea%5E2%7D%7B3a%5E-1%7D%20%29%5Ek)
To solve, plug in a and k.
![(\frac{3^(5)^2}{3*5^-1} )^-2](https://tex.z-dn.net/?f=%28%5Cfrac%7B3%5E%285%29%5E2%7D%7B3%2A5%5E-1%7D%20%29%5E-2)
3*5^2=75
(3*5)^-1 = 1/15
![75 / \frac{1}{15} = 5](https://tex.z-dn.net/?f=75%20%2F%20%5Cfrac%7B1%7D%7B15%7D%20%3D%205)
5^-2 = 1/25
Answer: 55
Step-by-step explanation:
x+125=180
subtract 125 on each side
when you do that 125 cancels out and your left with
180-125=55
