And the probability that they cheated and we can use the classical definition of probability given by:

$p =\frac{successes}{Total}$

And replacing we got:

$p=\frac{1162}{3630}= 0.320$

So then the probability of people cheated is 0.320 or 32% approximately

Find f(-10) f(x)=7x-5

Inessa [10]

Step-by-step explanation:

F(x) is simply another way of saying y. We are given the x value of -10. We can substitute this in for x and find y.

f(-10) = 7(-10) - 5

f(-10) = -70 - 5

f(-10) = -75
