Answer:

True

Step-by-step explanation:

The pages left = total pages - the pages read

(10b + 3) - (-2b +78)

10b + 2b + 3 - 78

12b - 75

The pages left is equal to 12b - 75

Commission: 10 percent on first $5,000; 15% over $5,000. Find the total graduate commission on $22,000.
natta225 [31]

Based on the information about the percentage, the commission that will be paid will be $3050.

<h3>How to solve percentage</h3>

From the information given, it was stated that there's a 10 percent on first $5,000 and 15% over $5,000.

The total graduate commission on $22,000 will be:

= (10% × $5000) + (15% × $17000)

= (0.1 × $5000) + (0.15 × $17000)

= $500 + $2550

= $3050

Elina [12.6K]

Answer: Margin of error = 6.58

Confidence interval =  (26.91, 40.08)

Step-by-step explanation:

Since we have given that

Sample size n = 8

Sample mean = 33.5 minutes

Population standard deviation = 9.5 minutes

At 95% confidence interval,

α = 0.05

t = 1.96

So, Margin of error is given by

t\times \dfrac{\sigma}{\sqrt{n}}\\\\=1.96\times \dfrac{9.5}{\sqrt{8}}\\\\=6.58

Confidence interval would be

Lower limit:

\bar{x}-6.58\\\\=33.5-6.58\\\\=26.91

Upper limit:

\bar{x}+6.58\\\\=33.5+6.58\\\\=40.08

Hence, the interval would be (26.91, 40.08)

But at standard deviation 7.2 minutes, the confidence interval was (27.5, 39.5)

Confidence interval using the standard normal distribution is wider than the confidence interval using t distribution.
