Answer:
Step-by-step explanation:
Area of 19 by 29 rectangle = 551 sq ft
White space:
Area of large triangle = 0.5*15^2 = 112.5 sq ft
Area of 15 by 14 rectangle = 210 sq ft
Area of small triangle = 0.5*4^2 = 8 sq ft
Shaded area = 551 - 112.5 - 210 - 8 = 220.5 sq ft
So we are given the mean and the s.d.. The mean is 100 and the sd is 15 and we are trying the select a random person who has an I.Q. of over 126. So our first step is to use our z-score equation:
z = x - mean/s.d.
where x is our I.Q. we are looking for
So we plug in our numbers and we get:
126-100/15 = 1.73333
Next we look at our z-score table for our P-value and I got 0.9582
Since we are looking for a person who has an I.Q. higher than 126, we do 1 - P. So we get
1 - 0.9582 = 0.0418
Since they are asking for the probability, we multiply our P-value by 100, and we get
0.0418 * 100 = 4.18%
And our answer is
4.18% that a randomly selected person has an I.Q. above 126

You would pay $5.54 on that item.
Step-by-step explanation:
Given,
Cost of item = $63
Sales tax rate = 8.8%
Amount of sales tax = 8.8% of cost of item
Amount of sales tax = 
Amount of sales tax = 
Amount of sales tax = $5.54
You would pay $5.54 on that item.
