Lesley works as a cars salesperson. She makes a monthly base salary of $1500. She also earns a 4% commission on all sales beyond

Troyanec [42]

Answer:

$1,740

Step-by-step explanation:

Setting up an equation to solve for Lesley's total salary would be the sum of her monthly base salary ($1,500) and the amount of her commission for any sales over $20,000:

Salary = $1,500 + (sales - $20,000)(0.04)

Since Lesley sold $26,000 in sales this month, we can calculate her total salary and commission:

Salary = $1500 + ($26,000-$20,000)(0.04) or $1500 + ($6000)(0.04)

Salary = $1500 + $240 = $1,740.00

Answer:

The Margin of error = 0.01

Step-by-step explanation:

Explanation:-

step(i):-

Given confidence interval for the proportion of vacationers traveling abroad

(0.14,0.16)

The 95% of confidence interval for Population proportion with margin of error is determined by

( p⁻ - M.E , p⁻ + M.E)

step(ii):-

The margin of error is determined by

$M.E = Z_{\alpha } \sqrt{\frac{p(1-p)}{n} }$

Given Confidence interval is ( 0.14 , 0.16 )

Now

(( p⁻ - M.E , p⁻ + M.E) = (0.14,0.16)

Equating

p⁻ - M.E = 0.14 ...(i)

p⁻ + M.E = 0.16 ...(ii)

Solving (i) and (ii) equations , we get

p⁻ - M.E = 0.14

p⁻ + M.E = 0.16

- - -

- 2 M.E = -0.02

M.E = 0.01

The margin of error = 0.01

Conclusion:-

The margin of error = 0.01
