Answer:
And the probability that they cheated and we can use the classical definition of probability given by:
And replacing we got:
So then the probability of people cheated is 0.320 or 32% approximately
Step-by-step explanation:
For this problem we know that in a survey of students, 1162 stated they cheated and 2468 stated they did not.
The total of people is given by:
And the probability that they cheated and we can use the classical definition of probability given by:
And replacing we got:
So then the probability of people cheated is 0.320 or 32% approximately
Circumference=2(pi)r or (pi)d
You know that Circumference=113.04
You know that the diameter=2x+4
Plug what you know into the equation and solve for x.
C =(pi) d
113.04=(pi)(2x+4)
Answer:
10π
Step-by-step explanation:
Length of the arc = circumference
Circumference formula = 2πr, for a circle, so for a semicircle, it is just πr
r=10
answer = 10π

Answer:
- 4% fund: $39,000
- 52% fund: $1000
Step-by-step explanation:
Let x represent the amount invested at 52%. Then (40000-x) is the amount invested at 4%. The total annual interest is ...
0.52x +0.04(40000-x) = 2080
0.48x = 480 . . . . . . . . . subtract 1600, simplify
x = 1000 . . . . . . . . . divide by 0.48
Then the amounts invested in each fund are ...
4% fund: $39,000
52% fund: $1000
