Roxie is picking out some movies to rent, and she is primarily interested in horror films and foreign films. She has narrowed down her selections to 20 horror films and 8 foreign films. Step 2 of 2 : How many different combinations of 3 movies can she rent if she wants at least two horror films

Answers

Answer:

2470

Step-by-step explanation:

Roxie must pick 3 movies from 20 horror films and 8 foreign films with at least two horror films.

i) She can pick 2 horror films and 1 foreign film

The number ways this is possible = C(20, 2) * C(8, 1)

[tex]C(20,2)=\frac{20!}{(20-2)!2!}=190\\\\C(7,1)=\frac{7!}{(7-1)!1!}=7[/tex]

The number ways this is possible = C(20, 2) * C(8, 1) = 190 * 7 = 1330

ii) She can pick 3 horror films

The number ways this is possible = C(20, 3)

[tex]C(20,3)=\frac{20!}{(20-3)!3!}=1140\\\\[/tex]

The number ways this is possible = C(20, 3) = 1140

The number of ways of picking 3 movies from 20 horror films and 8 foreign films with at least two horror films = pick 2 horror films and 1 foreign film + pick 3 horror films

The number of ways of picking 3 movies from 20 horror films and 8 foreign films with at least two horror films = 1330 + 1140 =2470

Answers

Answer:

The composition of f(g(x)) is:

[tex]f(g(x)) = -x^2-10x-26[/tex]

Step-by-step explanation:

Given two functions are:

[tex]f(x) = -x^2-1\\g(x) = x+5[/tex]

we have to find the composition of f and g which can also be written as: fog(x) or f(g(x))

The method to find the composition is that we will put the function g in place of x in function f

[tex]f(g(x)) = -(x+5)^2-1\\=-(x^2+25+10x)-1\\=-x^2-25-10x-1\\=-x^2-10x-26[/tex]

Hence,

The composition of f(g(x)) is:

A researcher observes the level of aggression of six 5-year-old boys over the course of a school day. The number of incidents for the group of boys was 2, 4, 6, 12, 8, 10. What is the mean number of aggressive acts for this group of children

Answers

Answer:

Step-by-step explanation:

Mean number = Sum of all the numbers/ Total number of old boys

Given the data

2, 4, 6, 12, 8, 10

Sum = 2+4+6+12+8+10

Sum = 42

Total number of old boys = 6

Substitute into the formula

Mean number of aggressive acts = 42/6

Mean number of aggressive acts = 7

Hence the mean number of aggressive acts for this group of children is 7
