Answer:

The mistake is to make \frac{15}{16}=\frac{3}{5}

The correct answer \frac{3}{4}

Step-by-step explanation:

This is the operation performed by Kali:

\frac{15}{16}*\frac{4}{5}=\frac{4}{5}*\frac{3}{5}=\frac{12}{25}

but 15/16 ≠3/5, so knowing this   \frac{a}{b}*\frac{c}{d}=\frac{a}{d}*\frac{c}{b}  ,  then

\frac{15}{16}*\frac{4}{5}=\frac{15}{5}*\frac{4}{16}=3*\frac{1}{4}=\frac{3}{4}

A research company surveys 8,000 people. The company expects 6,000 people to respond favorably. If there is a percent error of 2
Aliun [14]

Answer:

400

Step-by-step explanation:

6/8 = 0.75 or 75% expected to respond favorably.

Margin of error 2.5%:

  Lower bound: 0.75 - .025 = 0.725

  Upper bound: 0.75 + .025 = 0.775

Range:

  Lower bound: 8000 * 0.725 = 5800

  Upper bound: 8000 * 0.775 = 6200

  6200 - 5800 = 400
