Answer:

The actual length of the helicopter is <u>23 feet</u>.

Step-by-step explanation:

Given:

On a scale drawing, a helicopter is 2.3 feet long.

The scale on the drawing shows a ratio of 1 foot to 10 feet.

Now, to find the actual length of the helicopter.

Let the actual length of helicopter be x.

On scale drawing length of helicopter = 2.3 feet.

The scale on the drawing shows a ratio = 1:10.

Now, as ratios are given so by setting proportion we solve it:

\frac{2.3}{x} =\frac{1}{10}

<em>By cross multiplying we get:</em>

⇒ 2.3\times 10=x

⇒ 23=x

⇒ x=23\ feet.

Therefore, the actual length of the helicopter is 23 feet.

expeople1 [14]

Answer:

B. The width of the confidence interval would be smaller.

Step-by-step explanation:

By reducing the confidence level from 99% to 95%, the student assumes that there is more uncertainty about the new confidence interval than the previous one. That, being said, since the results aren't as certain, the confidence interval is widened towards a central average point because the new interval isn't as accurate.

Therefore, the answer is B. The width of the confidence interval would be smaller.
