A zoo randomly sampled three groups of 100 people on what their favorite type of bear is. The data shows the results of the three samples. Black Bear Grizzly Bear Polar Bear Total
Group 1 24 30 46 100
Group 2 23 34 43 100
Group 3 22 29 49 100

The zoo has 3380 visitors one weekend.

Based on the samples, what is a reasonable estimate of the number of people who will prefer polar bears?

Enter your answer rounded to the nearest whole number in the box.

1555 people

Step-by-step explanation:

First, average the votes for polar bears.

(46 + 43 + 49)/3 = 46

Next, make the variable x equal to the estimate of the number of people who will prefer polar bear out of the 3380 people and set up your proportion equation.

x/3380 = 46/100

x = 1554.8

Round to the nearest whole number to get 1555.

25

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
