[Problem 2]

-> Girls = 226  

-> Boys = 295

-> Girls with glasses = 104  

-> Boys with glasses = 210    

-> Difference of total boys and girls = 69  

-> Difference of boys with glasses vs without glasses = 85  

-> Difference of girls with glasses vs without glasses = 122

-> <em>It is hard to create a table over Brainly</em>

[Problem 4] Answer is 4.3

-> To find the mean absolute deviation, we will find the mean of the data and then see how far away each point is, and then find the mean of those values

-> Finding mean: \frac{38+46+52+44+47+55}{6} = 47

-> All the values (all of the values will be absolute values, why the word absolute is there, so ignore all negative signs!)

38 - 47 = 9

46 - 47 = 1

52 - 47 = 5

44 - 47 = 3

47 - 47 = 0

55 - 47 = 8

-> Then, we will find the mean of these values: \frac{8+0+3+5+1+9}{6} = 4 \frac{1}{3}

->  4 \frac{1}{3} = 4.33333 and when rounded to the nearest tenth is 4.3

Have a nice day!

What is the period of the graph of y = 5 sin (pi x) + 3?
Natasha2012 [34]

Equate whats inside (arguments) \sin with base period of sine function 2\pi and solve for x to get period,

\pi x=2\pi\implies x=2

So the period of the graph of the given function is precisely 2.

Hope this helps :)

The area of the triangle is 33.6 square inches. If the h eyesight of the triangle is 4 inches what is the length of the base
DerKrebs [107]
Using the formula for the area of a triangle we can solve for the base.

The formula for area of a triangle is : Area = 1/2 x base x height

We are given the area and the height:

33.6 = 1/2 x 4 x base

Multiply both sides by 2 to remove the 1/2:

67.2 = 4 x base

Divide both sides by 4 to solve for the base:

67.2 /4 = 16.8
 
Check: Area = 1/2 x 4 x 16.8 = 33.6

The base is 16.8 inches.
