7 0

Answer:

Company X - 190 students

Company Y - 114 students

No phones - 76 students

Step-by-step explanation:

1) Find a multiplier to get the ratio from sample to population; to compare the sample to the population

380/120 = 3.16666667 or 3 & 1/6

380 comes from the total population of students and 120 comes from the randomly selected.

2) Use our multiplier to compare the results to the population

<u>People with Company X</u>

  • 60 * 3.16667 = 190

<u>People with Company Y </u>

  • 36 * 3.166667 = 114

<u>People with no cell phone</u>

  • 24 * 3.166667 = 76.0000000001 = 76 (rounded)

<u>Double check</u>

190 + 114 + 76 = 380

What is the approximate area of the figure that is shaded in blue below?
Aleks [24]

Answer:

A: 48in2

Step-by-step explanation:

Area of a rectangle = Length x Width

The complete figure is rectangular in shape with:

Length = 11 in

Width = 5 in

Area = 11 x 5

Area = 55 in2

The pink part is triangular in shape with:

height = 4in

Base = 3.5 in

Area of a triangle = 0.5 x base x height

Area of the pink portion = 0.5 x 3.5 x 4

Area of the pink portion = 7 in2

Area of the blue portion = (total Area) - (Area of the pink portion)

Area of the blue portion = 55 in2 - 7 in2

Area of the blue portion = 48 in 2

Hope this help you!
