Answer: The mean is 49.
Step-by-step explanation:
First add up all the numbers.
48 + 51 + 48 + 48 + 50 = 245
Then divide 245 by the amount of numbers are in your data (there are five numbers).
245 ÷ 5 = 49
a) Parallel for both line segments have the same slope = -5/4
b) 55º
Step-by-step explanation:
a) To verify the parallelism of these line segments, It's necessary to find the slope of each one. Parallel lines share the same slope value:

b) If ∠DAB = 125°, what is the measure of ∠CBA? Justify your reasoning.
Those beams do not form a parallelogram because:
Using the formula of distance between those points

So this is a trapezoid. And two adjacent angles within a trapezoid are supplementary, so If ∠DAB = 125º then 180 - ∠CBA=55º
C because i did it and got it right
10/24.
If you find the LCM of the denominators, you change the denominators to that, then take the LCM / denominator and multiply the numerator by that, making 18/24 and - 8/24. subtract with the numerators: 18 - 8 = 10. the result is 10/24
2 4/10 = 2.4
hope this helped
