We have

$\displaystyle \int_{-2}^2 f(x) \, dx - \int_{-2}^{-1} f(x) \, dx = \int_{-1}^2 f(x) \, dx$

so that

$\displaystyle \int_{-2}^2 f(x) \, dx + \int_2^5 f(x) \, dx - \int_{-2}^{-1} f(x) \, dx \\\\ ~~~~~~~~~~~~ = \int_{-1}^2 f(x) \, dx + \int_2^5 f(x) \, dx \\\\ ~~~~~~~~~~~~ = \boxed{\int_{-1}^5 f(x) \, dx}$

netineya [11]

Answer:

The probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47

Step-by-step explanation:

Has Gained Weight Has Not Gained Weight

Does not take vitamins 52 19

Takes one vitamin per day 35 49

Takes more than one vitamin per day 72 80

We are supposed to find the probability that he or she has gained weight, given that he or she takes more than one vitamin per day

A= he or she has gained weight

B=he or she takes more than one vitamin per day

$P(A|B)=\frac{P(A \cap B)}{P(B)}$

$A \cap B = 72$

B = 72+80=152

So, $P(A|B)=\frac{72}{152}=0.47$

So, Option C is true

Hence the probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47
