Write the equation in slope-intercept form of the line that has a slope of -2 and y-intercept of 2.

bixtya [17]

Answer:

y= -2x +2

Step-by-step explanation:

<u>Slope-intercept form:</u>

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is -2, m= -2.

Substitute m= -2 into the equation:

y= -2x +c

Given that the y-intercept is 2, c= 2.

Substitute c=2 into the equation:

y= -2x +2

Sammy counts the number of people in one section of the school auditorium. He counts 18 female students, 16 male students, and 6

Rzqust [24]

Correct Question:

He counts 18 female students, 16 male students, and 6 teachers. There are

720 people in the auditorium. Consider the probability of selecting one person

at random from the auditorium.

Which of these statements are true?

Choose all that apply.

A: The probability of selecting a teacher is 6%.

B : The probability of selecting a student is 85%.

C : The probability of selecting a male student is 32%.

D : The probability of selecting a female student is 45%.

Step-by-step explanation:

Option B and D are correct because

The total number of people in one cross section = 18 + 16 + 6 = 40.

A = The probability of selecting a teacher is = (6/40)x100 = 15 % not equal to 6 %

B = The probability of selecting a male student is = (34/40)x100 = 85%

C = The probability of selecting a male student is = (16/40)x100 = 40 % not equal to 32 %

D : The probability of selecting a female student is = (18/40)x100= 45%

The university police department keeps track of the number of tickets it write in a year. Last year the campus police wrote 1460

AlladinOne [14]

Answer:

Step-by-step explanation:

We are given that Ticket writing on campus follows a Poisson process.

Last year the campus police wrote 1460 tickets

So, $X \sim Poisson (1460 / year)$

1 year = 365 days

So, E(Y) = $\frac{1460}{365}=4$

So, the standard deviation of the number of tickets written per day by the campus police = $\sqrt{4} =2$

Hence the standard deviation of the number of tickets written per day by the campus police is 2

C 80 km 39 km What is the length of the hypotenuse?

Tresset [83]

Answer:

89 km

Step-by-step explanation:

a^2+b^2=c^2

80^2+39^2=c^2

6400+1521=c^2

7921=c^2

sqrt of 7921=89
