Solve 2(4 x + 3) < 5 x + 21. { x | x < 9} { x | x > -5} { x | x > -9} { x | x < 5}

Nesterboy [21]

Answer:

x <5

Step-by-step explanation:

2(4 x + 3) < 5 x + 21

Distribute

8x +6 < 5x +21

Subtract 5x from each side

8x -5x +6 < 5x-5x+21

3x +6 < 21

Subtract 6 from each side

3x+6-6 <21-6

3x <15

Divide each side by 3

3x/3 <15/3

x <5

Tanya [424]

Answer:

a) Margin of error = 166.311

b) sample size ≥ 62

Step-by-step explanation:

Given:

Average cost = $1599

Sample size = 50 persons

Standard deviation = $600

Confidence level is 95%

a) Margin of error = $z\frac{\sigma}{\sqrt{n}}$

Now for confidence level of 95% z-value = 1.96

Thus,

Margin of error = $1.96\frac{600}{\sqrt{50}}$

Margin of error = 166.311

b) For Margin of error ≤ 150

$z\frac{\sigma}{\sqrt{n}}$ ≤ 150

$1.96\frac{600}{\sqrt{n}}$ ≤ 150

$1.96\frac{600}{150}$ ≤ √n

√n ≥ 7.84

n ≥ 61.4656

Therefore,

sample size ≥ 62
