Answer:
<u>18.8%</u>
Step-by-step explanation:
For calculating this, focus on one part of the table :
- The row where students do not like sandwiches
There are 32 students who do not like sandwiches, and 6 of them do not like pies. Take this a proportion :
- P (does not like pies, do not like sandwiches) = 6/32
- P = 3/16
- P = <u>18.8%</u>
(1/A) dA/dt= C where A is the population of ants and C is a constant
ln(A) = C*t + C1 where C1 is another constant that comes out of integration and t is time in days.
Plugging in: at t=0, A= 100 so C1 = ln(100) = 4.605
at t=3, A=230 so ln(230) = 3*C +4.605 so C = 0.278
Final equation:
ln(A) = 0.278t + 4.605
or:
A = exp(0.278t + 4.605)
After 14 days, A = exp(0.278*14 + 4.605) = 4875.2
6x - 12 = 8x + 14
2x = - 26
x = - 13
I think it's D. The area of A is k2 times the area of rectangle B
You simply put 40 over a hundred and 55 over n (which is the number were trying to find) so you do cross multiplication. 55 times a hundred and after you get the answer. You divide it by 40 and should get 137.5.
