Answer:
35/100
Step-by-step explanation:
You have to find how many juniors there are, so if you add 13, 20, and 2 you get 35. For the denominator you have to find the total number of students, so just add all of the numbers together to get 100. So there is a 35/100 chance that a randomly selected student is a junior.
Answer:
x<-2
Step-by-step explanation:
Divide both sides of the inequality by 5 to solve for x.
Answer:
The senior class will have 100 members in the 13th year.
Step-by-step explanation:
Use the compound interest equation with a negative interest rate:
A = P(1 + r/n)^(n)(t)
Let n be 1 since we're looking for a specific year.
100 = 250(1 - 0.07)^t
100/250 = (0.93)^t
0.4 = (0.93)^t
t = 13 years
Given function:
To find:
The input if the output is 32.
The output if the input is 4.
Solution:
Input is x and output is c.
Substitute c = 32 in f(x).
Divide by 4 on both sides, we get
Taking cube root on both sides.
The input is 2 if the output is 32.
Substitute x = 4 in f(x).
The output is 256 if the input is 4.
