the probability that a twelve year old has a brother or sister is 25%. suppose you survey 300 twelve year olds. about how many d
Genrish500 [490]

Answer:

n(B U S) = 75

Step-by-step explanation:

Explanation:-

<u>Probability</u>:-

P(E) = \frac{number of elements events in E}{total number of elementary events in the random experiment}

P(E) = \frac{m}{n}

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) =\frac{n(BUS)}{n(survey)}

substitute given values, we will get solution

0.25 = \frac{n(BUS)}{300}

after cross multiplication , we get

n(BUS) = 0.25 X 300

n(BUS) = 75

The variables x and y have a proportional relationship, and y= 2/5 when x = 5/8
Archy [21]

Answer:

B. 16/25 x is the answer

Step-by-step explanation:

lets find the proportional relationship,

y = kx

2/5 = k * 5/8

k = (2/5) /  (5/8)

k = 16/25

so if k, constant is 16/25

<u>equation is:</u>

<em>y = 16/25 x</em>
