Chart relating to the question is attached below.

Answer:

349 students

Step-by-step explanation:

Based on the chart given, we can obtain the experimental probability or proportion for the travel plan of 75 students :

Proportion who would be traveling by car :

Number traveling By car / number of samples

p(car) = 23 / 75 = 0.30666

If total number of students = 1138

Using the proportion obtained from the sample, the number of students who would be traveling by car from the population would be :

= 0.30666 * 1138

= 348.98 students

= 349 students

What is the radius of a sphere if its surface area is 2,122.64 square inches? (Use 3.14 for .)

Lady_Fox [76]

$\bf \textit{surface area of a sphere}\\\\
SA=4\pi r^2~~
\begin{cases}
r=radius\\
------\\
SA=2122.64
\end{cases}\implies 2122.64=4\pi r^2
\\\\\\
\cfrac{2122.64}{4\pi }=r^2\implies \cfrac{530.66}{\pi }=r^2\implies \sqrt{\cfrac{530.66}{\pi }}=r$
