Answer:
2x +5x-20+3x=180(angle of triangle)
10x-20=180
10x=180+20
10x=200
x=200/10
x=20

What is the interquartile range of the data set?
8_murik_8 [283]
Answer:
IQR = 8
Step-by-step explanation:
The interquartile range (IQR) is the difference between the upper quartile Q₃ and the lower quartile Q₁
We require the data arranged in ascending order and to find the median Q₂
The median is the middle value of the data arranged in ascending order.
8, 9, 9, 9, 10, 11, 13, 15, 17, 18, 22
↑ Q₂
The upper quartile is the middle value of the data to the right of the median
13, 15, 17, 18, 22
↑ Q₃
The lower quartile is the middle value of the data to the left of the median
8, 9, 9, 9, 10
↑ Q₁
IQR = Q₃ - Q₁ = 17 - 9 = 8
If it wants you to solve for b the answer is b = -4/3c + a/3
And if it wants you to solve for C the answer is c = -3/4b + 1/4a
Answer:
11/10 or 1 1/10 or 1.1
Step-by-step explanation:
7/10+2/5
7/10+4/10 you want to make the denominator the same
11/10 now that the denominators are the same you can add the numerators
