The probability that a twelve-year-old has a brother or sister is 25%. supposed you survey 300 twelve-year-olds. about how many

vazorg [7]

Answer:

n(B U S) = 75

Step-by-step explanation:

P(E) =

Let 'B' be the event of having twelve year old brother

Let 'S' be the event of having twelve year old sister

given data P(BUS) = 0.25

given total survey n(survey) = 300

we have to find the value is n(BUS) =?

we will use probability definition we get, P( BUS) =

substitute given values, we will get solution

after cross multiplication , we get

n(BUS) = 0.25 X 300

n(BUS) = 75

What is the slope of the line? y + 1 = 3(2x - 4)

Alexeev081 [22]

Answer: 6

Step-by-step explanation:

Let's start by getting the equation to slope intercept form

First simplify

$y + 1 = 3(2x - 4)\\\\y+1=6x-12$

Then get y by itself

$y+1-1=6x-12-1\\y=6x-13$

In slope intercept form y=mx+b, m is the slope

In this case the slope is 6

Find the standard form of the equation of the ellipse satisfying the following conditions. Major axis vertical with length 14;

Evgesh-ka [11]

Answer:

The answer to your question is below

Step-by-step explanation:

Data

Mayor axis vertical = 14

Minor axis = 10

Center = (-7, 3)

Formula

Mayor axis = 2a

Minor axis = 2b

$\frac{(x-h)^{2} }{b^{2} } + \frac{(y - k)^{2} }{a^{2} } = 1$

Process

2a = 14 2b = 10

a = 7 b = 5

h = -7 k = 3

Substitution

$\frac{(x+7)^{2} }{5^{2} } + \frac{(y - 3)^{2} }{7^{2} } = 1$
