8/2(2+2)=X
8/2(4)=X
4(4)=X
16=X
Your answer would be X=16
Answer:
4
Step-by-step explanation:
Add each sample separately
A.17 B. 47 C. 39 D. 52 E. 45
Then you add them all together which totals 200 sick days
We know that they surveyed 5 schools and 10 students at random from each one. So we want to know the mean of sick days the students took not the schools in all.
So we divide 200/50
And get a mean of 4.
So each student took an average of 4 sick days each in the country.
Answer:
a. write a linear function for the number of gallons of gas in the tank in terms of the number of miles driven.
Answer:
valid
Step-by-step explanation:
it's valid because for example here are some even numbers, 0, 2, 4, 6, 8, they're are all multiples of four.
hope that helped :)
mark me brainliest pls
Find the unit rate first, and then multiply it by 8:
2 3/5 boxes
---------------- = 13/5 divided by 7/2.
3 1/2 roofs
You can obtain the correct result by inverting the divisor, 7/2, and then multiplying:
13/5 times 2/7. This comes out to 26/35. That represents 26/35 box of nails per roof.
To do 8 roofs (not roves), you'd need (26/35)(8/1) boxes: 5.94 boxes. Why not buy 6 boxes to be sure you'll have enough?
