To solve this problem, the formula can be used
I = P / T
Where I is the fraction of the sample
P is the amount of the sample
T is the total amount of sample
Since P = 252 chicken sandwiches and I = 0.55
And solve for T
T = 252 / 0.52
<span>T = 458 sandwiches in total</span>
Answer:
c
Step-by-step explanation:
The median is half the sum of the parallel bases, that is
UV =
3 + 20x = ( multiply both sides by 2 to clear the fraction )
6 + 40x = 15 + 31x ( subtract 31x from both sides )
6 + 9x = 15 ( subtract 6 from both sides )
9x = 9 ( divide both sides by 9 )
x = 1
Then
UV = 3 + 20x = 3 + 20(1) = 3 + 20 = 23 → c
X = 47
because
100-6= 94
94 divided by 2 = 47
You should not calculate the routines but instead you should calculates how much it is front and center.
