Answer:
Step-by-step explanation:
Exterior angle of a triangle is equal to the sum of opposite interior angles
13b - 48 = (9b - 47) + (b + 44)
Add the like terms
13b - 48 = 10b - 3
Add 48 to both the sides
13b - 48 +48 = 10b - 3 +48
13b = 10b + 45
Subtract 10b from both sides
13b - 10b = 10b + 45 - 10b
3b = 45
Divide both sides by 3
3b/3 = 45/3
b = 15
Answer:
Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.

Answer:
k = 2.5
Step-by-step explanation:
The standard form of a proportional equation is
y = kx ← k is the constant of proportion
y = 2.5x ← is in this form
with k = 2.5

Answer:
infinite solutions
Step-by-step explanation:
y=5/2x+2
2y= 5x +4
Multiply the first equation by 2
y = 5/2 x +2
2y = 5/2 *2 x +2 *2
2y = 5x +4
Since this is identical to the second equation (they are the same), the system of equations has infinite solutions
