Hello,
Do you mean
h(x)=2x+5
g(x)=8-3x
h(g(x))=h(8-3x)=2(8-3x)+5=16-6x+5=21-6x
h(g(1.5))=h(g(3/2))=21-6*3/2=21-9=12

Answer:
Step-by-step explanation:
Let's set up a proportion.
He can peel 125 oranges in 5 hours. First, let's find the minutes in 5 hours.
There are 60 minutes in 1 hour, so multiply 60 and 5 (60*5=300). There are 300 minutes in 5 hours.
We don't know how many oranges he can peel in 12 minutes. So we say he can peel x oranges in 12 minutes.
Solve for x by isolating it. x is being divided by 12. The inverse of division is multiplication. Multiply both sides of the proportion by 12.
Rob can peel 5 oranges in 12 minutes.
The 3rd or 1st one I'm not sure which one but u have an idea of what it might be
Mean= is the summation of the maximum temperatures ÷ the numbers of times the temperatures where recorded
standard deviation= is a number used to tell how measurements for a group are spread out from the average (mean), or expected value.
A low standard deviation means that most of the numbers are very close to the average.
A high standard deviation means that the numbers are spread out.
Variance= is a way to measure how far a set of numbers is spread out.
A variance of zero indicates that all of the data values are identical. All non-zero variances are positive.
A small variance indicates that the data points tend to be very close to the mean, and to each other.
A high variance indicates that the data points are very spread out from the mean, and from one another.
