0.7(3x−0.2)=0.3(0.8−2x) URGENT 20 Points! Please Help!!!

topjm [15]

Answer:

x = .140741

Step-by-step explanation:

0.7(3x−0.2)=0.3(0.8−2x)

Distribute

.7 * 3x - .7*.2 = .3*.8 - .3 * 2x

2.1x - .14 = .24 - .6x

Add .6x to each side

2.1x +.6x -.14 = .24 -.6x+.6x

2.7x -.14 = .24

Add .14 to each side

2.7x -.14+.14 = .24+.14

2.7x = .38

Divide by 2.7 on each side

2.7x/2.7 = .38/2.7

x = .140741

In a city, 60% of the residents live in houses and 40% of the residents live in apartments.Of the people who live in houses, 20%

DIA [1.3K]

Answer:

0.75 or 75%

Step-by-step explanation:

The probability that a resident lives in a house and owns their own business is:

$P(H\cap B)=0.6*0.2\\P(H\cap B)=0.12$

The probability that a resident lives in an apartment and owns their own business is:

$P(A\cap B)=0.4*0.1\\P(A\cap B)=0.04$

Therefore, the probability that a person lives in a house, given that they own their own business is:

$P(H|B) = \frac{P(H\cap B)}{P(H\cap B)+P(A\cap B)}\\P(H|B) = \frac{0.12}{0.12+0.04} \\P(H|B) = 0.75$

The probability is 0.75 or 75%.
