Exhibit 2-4A survey of 400 college seniors resulted in the following crosstabulation regarding their undergraduate major and whe
Misha Larkins [42]

Answer:

The percentage of college seniors with "Other" majors is 32%.

Step-by-step explanation:

The total number of college seniors surveyed is, <em>N</em> = 400.

The number of college seniors with "Other" majors is, <em>n</em> = 128.

The percentage of a value of <em>x</em> from <em>N</em> total is given as follows:

\text{Percentage of}\ x=\frac{x}{N}\times 100\%

Compute the percentage of college seniors with "Other" majors as follows:

\text{Others}\%=\frac{n}{N}\times 100\%

              =\frac{128}{400}\times 100\%\\\\=32\%

Thus, the percentage of college seniors with "Other" majors is 32%.

-——-————
9y

Find the surface area of the Rectangular Pyramid. Please see the attachment, of course 45 yards ^2 is not the correct answer. Th
zheka24 [161]

Answer:

Surface area = 39 yards²

Step-by-step explanation:

∵ the surface area of the pyramid = 1/2 pl + base area

  Where p = perimeter of the base , l = slant height

∵ Area of the base = 3 × 3 = 9 yards²

∵ Perimeter of the base = 4 × 3 = 12 yards

∵ Slant height = 5 yards

∴ The surface area = 1/2 × 12 × 5 + 9 = 39 yards²
