A group of people were asked if they had run a red light in the last year. 290 responded "yes", and 177 responded "no". Find the probability that if a person is chosen at random, they have run a red light in the last year.

Answers

Answer 1

Answer:

0.621

Step-by-step explanation:

Number of people that have run a red light in the last year = 290

Number of people that have not run a red light in the last year = 177

Total number of respondents = 290 + 177

                                                 = 467

Pr(if a person is chosen at random, they have run a red light in the last year) = [tex]\frac{number of people who has run the red light last year}{total number of respondents}[/tex]

                   = [tex]\frac{290}{467}[/tex]

                   = 0.621

The probability that if a person is chosen at random, they have run a red light in the last year is 0.621.

1. The ratio of boys to girls is 4/5. If there
are 24 boys, how many girls are there?

Answers

Given:

The ratio of boys to girls is [tex]\dfrac{4}{5}[/tex].

Number of boys = 24

To find:

The number of girls.

Solution:

We have,

Boys: Girls = 4:5

Let the number of boys be 4x and number of girls be 5x.

[tex]4x=24[/tex]

[tex]x=\dfrac{24}{4}[/tex]

[tex]x=6[/tex]

Now,

Number of girls = [tex]5x[/tex]

                          = [tex]5(6)[/tex]

                          = [tex]30[/tex]

Therefore, the number of girls is 30.

A. For each input value, x, there is exactly one output value, y.

Step-by-step explanation:

A function always have exactly one output value (y-value) that is related or assigned to each input value (x-value), however, two different x-values can have the same y-value.

In the graph given, although two different values have the same y-value, every x-value has exactly one y-value corresponding to it. No x-value has two different y-values.

Therefore, the graph represents a function.

Answer:

Since there are already 2 angles shown, which are 48 and 90 (indicated by the square in the bigger triangle, we can set up an equation.

48 + 90 + y = 180

138 + y = 180

-138 + 138 + y = 180 - 138

y = 42°

Write down in terms of n an expression of the nth terms?

Answers

Answer:

A. nth term = 4 + (n - 1) -3

B. nth term = -7 + (n - 1) -5

Step-by-step explanation:

A. 4, 1, -2, -5, -8

First term, a = 4

Common difference, d = 1 - 4 = -3

nth term = a + (n-1)d

nth term = 4 + (n - 1) -3

B. -7, -12, -17, -22, - 27

First term, a = -7

Common difference, d = -12 - (-7)

= -12 + 7

= -5

nth terms = a + (n - 1)d

nth term = -7 + (n - 1) -5
