Mrs. lane took a survey of the types of pants her students were wearing. she collected the data at the right. what percent of her students were wearing shorts

It is always important to go through the given problem first to get a concept of the requiremement. Then all the information's available from the question has to be noted down in such a manner that there would be no need to look at the question while solving.

Total number of students wearing jeans = 10

Total number of students wearing shorts = 9

Total number of students wearing capris = 2

Then the total number of students surveyed by Mrs Lane = (10 + 9 + 2)

                                                                                           = 21

Now percentage of students wearing shorts = (9/21) * 100

                                                                      = (3/7) * 100

                                                                      = 300/7

                                                                      = 42.85 percent

So a total percentage of 42.85% of the students were wearing shorts.

Step-by-step explanation:

The perimeter of the kite WXYZ is 33.94 square units

Step-by-step explanation:

Step 1; First we plot the points W, X, Y, Z on the graph. We need to find the distance between the opposite sides i.e W and Y, X and Z. To find the distance between W and Y, X and Z we use the formula

Distance = √ (x2 - x1)² + (y2 - y1)².

So for W (-3, 3) and Y (4, -4) where W is (x1, y1) and Y is (x2, y2).

Distance = √(4 - (-3))² + (-4 -3)² = √49 + 49 = √98 = 9.899.

Distance between X (2, 3) and Z (-3, -2) where X is (x1, y1) and Z is (x2, y2).

Distance = √(-3 -2)² + (-2 -3)² = √25 + 25 = √50 = 7.071.

Step 2; The parameter of a kite is given by 2 times the sum of the two distances between opposite sides.

Parameter = 2 × (9.899 + 7.071) = 2 × 16.97 = 33.94 square units.
