Answer:
142
Step-by-step explanation:
60+70=130
8+4=12
130+12=142
I believe m=1 sorry if I’m wrong.
The correct answer among the choices listed above is option 4. <span>Two parallel lines cut by a transversal can create all of the following types of angles except complementary angles. Complementary angles are two angles having the sum of 90 degrees. This is not created in parallel lines cut by a transversal line.</span>
Answer:
y = (-5/2)x + 27
Step-by-step explanation:
Use the point slope formula y = mx + b.
Replace m with -5/2, x with -8 and y with 7:
7 = (-5/2)(8) + b. Find the y-intercept, b:
7 = -20 = b, or b = 27
The equation of this line is y = (-5/2)x + 27.
Answer:
To find the mean, you add all the numbers together and then divide by the number of numbers (6).
4 + 12 + 20 + 24 + 32 + 40 = 132
132/6 = 22
To find the mean absolute deviation, you will find the distance between each number and the mean and then divide this by 6 as well.
(22-4) +(22-12)+(22-20)+(24-22)+(32-22)+(40-22)
18 + 10 + 2 + 2 + 10 + 18 = 60
60/6 = 10
The mean absolute deviation is 10.
The correct answer is that Stefano should have divided by 6 when finding the mean absolute deviation.
