**[Calc]**** ****Question*** *** Easy**

The tables give the heights, in feet, of 5 peaks in the Rocky Mountains and 5 peaks in the Appalachian Mountains.

What is the height, in meters, of Blanca Peak?

(Use 1 meter \(=3.28\) feet.)

A. 437.5

B. 4,375

C. 47,045

D. 47,068

**▶️Answer/Explanation**

Ans:B

To find the height of Blanca Peak in meters, we need to convert its height from feet to meters. Since \(1\) meter is equal to \(3.28\) feet, we can use this conversion factor.

Blanca Peak’s height in feet is \(14,350\). To convert this to meters, we divide by \(3.28\):

\[14,350 \text{ feet} \div 3.28 = 4,375 \text{ meters}\]

Rounding to the nearest tenth, the height of Blanca Peak in meters is \( 4,375\) meters.

**[Calc]**** ****Question*** *** Easy**

The tables give the heights, in feet, of 5 peaks in the Rocky Mountains and 5 peaks in the Appalachian Mountains.

For the given Appalachian Mountain peaks, the height of the highest peak is approximately what percent greater than the height of the lowest peak?

A. \(1.1 \%\)

B. \(9.9 \%\)

C. \(73.0 \%\)

D. \(101.1 \%\)

**▶️Answer/Explanation**

Ans:A

To find the percentage difference between the highest peak (Mount Mitchell) and the lowest peak (Balsam Cone) in the Appalachian Mountains, we can use the formula:

\[\text{Percentage difference} = \frac{{\text{Difference in heights}}}{{\text{Height of lowest peak}}} \times 100\%\]

The difference in heights is \(6,684 – 6,611 = 73\) feet.

So, the percentage difference is:

\[\frac{{73}}{{6,611}} \times 100\%\]

\[\approx 1.1\%\]

Therefore, the correct answer is option A: \(1.1\% \).

**[Calc]**** ****Question**** Easy**

A state representative wants to increase the amount of driving practice time required before a student can earn a driver’s license. The representative surveyed a random sample of 50 from the 250 students taking the driver’s education class at Jefferson High School.

The survey reported that 62% of students taking the class agree that driving practice time should be increased, with an associated margin of error of 5%.

Based on the results of the survey, how many of the students surveyed agree with the proposed change?

A. 19

B. 31

C. 124

D. 155

**▶️Answer/Explanation**

Ans: B

Given information:

- The survey was conducted on a random sample of 50 students from a total of 250 students taking the driver’s education class.
- The survey reported that 62% of the surveyed students agree with increasing the driving practice time.
- The associated margin of error is 5%.

To find the number of students who agree with the proposed change, we need to calculate 62% of the sample size (50 students).

62% of 50 students $= 0.62 × 50 = 31$ students

Therefore, the number of students surveyed who agree with the proposed change is 31.

Among the given options, the correct answer is B. 31.
