Suppose that in a large metropolitan area, 85% of all households have cable tv. Suppose you are interested in selecting a group

Viktor [21]

Solution :

Let X denotes the number of the households tha have a cable TV.

Percentage of household that have a cable TV = 85 %

$X \sim \text{Binomial}(6, 0.85)$

Here, we can see that each of the observations is independent and the number of the observations is fixed, n.

The probability of the success P is the same for each of the outcomes.

Therefore,

$P(X=4)= \binom{6}{4}0.85^40.15^2$

= 0.08324

Answer:

(5,4) is the solution

Step-by-step explanation:

2x + y = 14 --> y = -2x + 14

Substitute y = -2x + 14 into 3x - 2y = 7

3x - 2( -2x + 14) = 7

3x + 4x - 28 = 7

7x = 35

x = 5

y = -2(5) + 14

y = -10 + 14

y = 4
