Answer:
97%
Step-by-step explanation:
for such a question we can use the percentage numbers like real unit numbers, as we need to analyze just the percentage numbers and align them with another percentage number with the result of another percentage number.
so, we just use the percentage numbers and deal with mean values and such like with real unit numbers.
therefore we need to find x
(79 + 92 + 71 + 86 + x) / 5 = 85
as the sum of all numbers divided by the number of measurements is the mean value.
and so,
79 + 92 + 71 + 86 + x = 425
328 + x = 425
x = 97
so, the next site must be 97%, so that the average for the 5 surveys will be exactly 85%
Since y is 5.2 you can substitute it in your equations 5.2 = -5x - 40 then you do things like normal add 40 in both sides and divide -5 in both sides you get 9.04
Answer:
thanks haahhahahaha
Step-by-step explanation:
I'm assuming that the first word is "four", with that said, this equation is quite simple. All you need to do to find the price per gallon is divide the cost of four gallons by four.
16.80 ÷ 4 = $4.20
Area of parallelogram = bh
To solve for the height you'll have to divide the area by the base length.
Hope this helps :)
