The final exams have the smaller IQR

Olenka [21]3 years ago

To find interquartile range, you have to find quartile 1 and quartile 3. Then, you subtract to two to find interquartile range. To solve this problem, I first found quartile 1 and quartile 3 which are 80 and 92, respectively. Then I subtracted 80 from 92 which got me the interquartile range for the midterm data. Then, to find the interquartile range for the finals data, I did the same thing and I got 78 and 85 which gave me an interquartile range of 7. So, for the answer, I got c. the final exams.

Solve each equation y-6.72=253

diamong [38]

You just need to have the variable by itself, so move the -6.72 to the other side (that will make it +6.72)
So you should have this equation now: y = 253+6.72
Then just add them and you have this: y = 259.72
And that is your answer!

Hope I helped! <3

Pizzeria Napoli sells a round pizza with diameter 16 inches and a square pizza with side length 15 inches. Which of the two shap

zavuch27 [327]

Answer: Square, 24 square inches

Step-by-step explanation:

Given

Diameter of round pizza $d=16\ in.$

Side of square pizza $a=15\ in.$

Area of circle $\pi r^2$

The area of a square is $a^2$

$\therefore \text{Area of round Pizza}=\pi \times (\frac{16}{2})^2\\\Rightarrow A_1=\pi \times 8^2=201.088\ in.^2$

The area of square pizza is

$A_2=15^2=225\ in.^2$

Clearly, the area of square pizza is more and the difference in their area is

$\Rightarrow A_2-A_1=225-201.088=23.91\approx\ 24\ in.^2$

Evaluate t Divided 3/4 for T equal 9 3/4

Molodets [167]

T / 3/4 ; t = 9 3/4

9 3/4 / 3/4

9 3/4 = 39/4

39/4 / 3/4
39/4 x 4/3
39 x 4 = 156
4 x 3 = 12
156/12 / 4/4 = 39/3 = 13
