Put the numbers in order from smallest to largest:
15, 19, 20, 25, 25, 28, 29, 30, 35, 37, 38, 43
Part A:
minimum = 15
maximum = 43
Q1 = (25+20) /2 = 45/2 =22.5
Q2= (28+29) /2 = 57/2 = 28.5
Q3 = (35+37)/2 = 72/2 = 36
Part B: Range = Maximum - minimum = 43-15 = 28
C: IQR = Q3 - Q1 = 36 - 22.5 = 13.5
Answer:
The value of x is - 11
Step-by-step explanation:
Given as :
∠ M = (5x +90) °
∠ R = 55°
The sum of measure of angle M and R are complementary
Complementary Angle are those when sum of two angle equal to 90°
∵ Angle M and R are complementary in nature
∴ ∠ M + ∠ R = 90°
Or, (5x +90) ° + 55° = 90°
Or, 5x = 90° - 90° - 55°
Or, 5x = - 55°
∴ x = -
= - 11
Hence the value of x is - 11 Answer
I am going to show you the easiest, quickest and most direct way of doing it.
Take in account:
1) the result of applying a 20% discount is the same that multiplying times a factor of 0.8, which results from (100 - 20) / 100 = 80 /100 = 0.8
2) adding a 6.5% of tax is the same that multiplyiing by a factor of 1 + 6.5/100 = 1 + 0.065 = 1.065
With that
Super Sport store:
12 * 72.50 * 0.8 * 1.065 = 741.24
Double Dribble
Use that a disscount of 9% results in a factor o 0.91.
I amended the shipping fee data to 5.99 per pair of shoes.
12*54.75*0.91 + 5.99*12 = 669.75
Difference: 741.24 - 669.75 = 71.48

Answer:
1800
Step-by-step explanation:
Given in the question a polygon of 12 sides
Formula to calculate sum of interior angles of 12-gon is
<h3> (n – 2)180</h3>
where n is the number of sides
which in this case = 12
plug values in the formula above
(12 - 2)180
12*180 - 180(2)
2160 - 360
1800
Sum of measurements of the interior angles of a 12sided polygon is 1800
