Solve the inequality. 3x + 7 > 4x + 2

Mathematics
1 answer:
andrey2020 [161]4 years ago
8 0

Answer: The solution for the inequality is x < 5 .

Step-by-step explanation:

Solve inequality:

3x +7 > 4x +2

-Subtract 4x from 3x:

3x -4x +7 > 4x -4x+2

-x +7 > 2

Subtract both sides by 7:

-x +7 -7  > 2 -7

-x >-5

-When you are dividing by -1, the inequality would change:

\frac{-x}{-1} > \frac{-5}{-1}

x < 5

So, the result for the inequality is x < 5 .

Forty-five percent of households say they would feel secure if they had​ $50,000 in savings. You randomly select 8 households
Dmitriy789 [7]

Answer:

0.172 ; 0.0884 ; 0.9115

Step-by-step explanation:

Proportion or those who feel secure, p = 0.45

Sample size, n = 8

Using the binomial distribution formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

A.) p(x = 5)

P(x =5) = 8C5 * 0.45^5 * 0.55^3

P(x = 5) = 56 * 0.0184528125 * 0.166375

P(x = 5) = 0.1719248540625

P(x = 5) = 0.172

B.) P(x > 5)

P(x > 5) = P(x = 6) + P(x = 7) + P(x = 8)

P(x > 5) = 0.0703 + 0.0164 + 0.0017

P(x > 5) = 0.0884

C.) P( ≤ 5) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4) + P(x = 5)

Using the binomial probability calculator to obtain a direct solution :

P( ≤ 5) = 0.9115

12x-14=5x+21

7x=35

x=5

12x-14=12(5)-14=46

5x+21=5(5)+21=46
