1. Turn 40% into a decimal (0.40)
2. Multiply 8*0.40, which gets you 3.2
The answer is 3.2!
I think the answer is D. The median is (90=78)/2 = 84
Answer:
Below.-
Step-by-step explanation:
Because when a negative is taken to an even power the results is positive.
So (-3)^24 is positive as 24 is even, and is the same as 3^24, and so the whole expression
10 * (-3)^24 = 10 ^ 3^24.
Answer: first picture is for y=-5/3x + 3
Step-by-step explanation:
First 40 hours rate = $12 per hour.
Next 10 hours charge ( Upto 50 hours) = A half of $12 that is $6 per hour.
And after next 10 hours chrges ( More than 50 hours) = 2 times of initial rate, that is 2*12 = $24 per hours.
Let us take variale x for number of hours and f(x) is the function for total earning for x hours.
So, we can setup a piecewise function as
![f(x)=\left \{ {{12x \ \ \ \ 0](https://tex.z-dn.net/?f=f%28x%29%3D%5Cleft%20%5C%7B%20%7B%7B12x%20%5C%20%5C%20%5C%20%5C%200%3C%3D%20x%20%3C%3D%2040%7D%20%20%5Catop%20%7B6x%20%5C%20%5C%20%5C%20%5C%2040%3Cx%3C%3D50%7D%7D%20%20%5Catop%20%7B24x%20%5C%20%5C%20%5C%20%20%5C%20%5C%20%2050%20%3C%20x%7D%20%20%5Cright.)
Therefore,
70 hours can be divided into = 40 hours + 10 hours + 20 hours.
Total earning of 70-hour week = 12* 40 hours + 6 * 10 hours + 24*20 hours
= 480 + 60 + 480
= $1020.
Therefore, he earn $1020 for a 70-hour week.
