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

Find the value of X <br> (7x-1) (6x-1)

Aleks04 [339]

Answer:

x=14

Step-by-step explanation:

(7x - 1)° + (6x - 1)° = 180°

(13x - 2)° = 180°

13x = 182°

x = 182°/13

x = 14

A tourist starts off from town A and travels for 50km on a bearing of N80°W to town B. At town B, he continues for another 40km

bixtya [17]

Answer:

Town C is approximately 58.356 kilometers from town A.

Step-by-step explanation:

According to the statement, we understand that tourist travels from town A to town B (50 kilometers) at a direction of 80º west of north and from town B to town C (40 kilometers) at a direction of 20º east of north. Vectorially speaking, the resultant from town A to town C is described by the following formula:

$\vec r = (50\,km)\cdot (-\sin80^{\circ},\cos 80^{\circ})+(40\,km)\cdot (\sin 20^{\circ}, \cos 20^{\circ})$

$\vec r = (-35.560,46.270)\,[km]$

The distance from town A to town C is the magnitude of vector reported above, which is now calculated by Pythagorean Theorem:

$\|\vec r\| = \sqrt{(-35.560\,km)^{2}+(46.270\,km)^{2}}$

$\|\vec r\| \approx 58.356\,km$

Town C is approximately 58.356 kilometers from town A.
