Answer:

For every 5 movies on the list there are 2 comedy movies.

Step-by-step explanation:

In this question Colton has comedy movies = 8

                                             Action movies = 6

                                             Fantasy movies = 5

                                            Drama movies = 1

So total number of movies in his favorite list = 8+6+5+1 = 20

Now we have to calculate the ratio of each kind of movie out of total number of movies.

The ratio of Comedy movie to the total =\frac{8}{20} =\frac{2}{5}

Ratio of Action movies to the total =\frac{6}{20} =\frac{3}{10}

Ratio of Fantasy movie to the total= \frac{5}{20} =\frac{1}{4}

and the ratio of drama to the total number of movies =\frac{1}{20}

After analyzing these solutions we can say that for every 5 movies on the list, there are 2 comedy movies.

Arada [10]

Answer:

Step-by-step explanation:

Using normal distribution

z = (x - mean) / standard deviation

Nine percent of americans say they are well informed about politics in comparison to most people.

That means probability of success is p =9/100 = 0.09,

then probability of failure is

q = 1-p =1 -0.09= 0.91

n = number of sample = 200

x=(8% of 200) = 0.08×200 =16

mean = np = 200×0.09= 18

Standard deviation = npq = 200×0.09×0.91= 16.38

We are looking for the probability that less than 8% of the people sampled will answer yes to the question

8% of 200 = 16

P (x greater than 16) =P(x lesser than/equal to 15)

z = 15-18 /16.38 = -3/16.38

= -0.18

Looking at the normal distribution table

P(x greater than 16) = 0.5714

What is the discriminant of this equation?<br> 3x2 + 8x = 0
Likurg_2 [28]
If the 2 is an exponent, it should be marked as such.
“3x2” means 3x⋅2
“3x^2” means 3x²

3x²+8x = 0
Discriminant = 8²-4(3)(0) = 64
