Answer: 18
Step-by-step explanation: Angles opposite of each other in a trapezoid equal 180 minus each other so 180 - 105 = 75 so 75 = 4y + 3
Subtract 3 from both sides
72 = 4y
Divide by 4
y = 18
Answer:
Mean : ≈ 12.7
Median: ≈ 13.5
Step-by-step explanation:
To find the mean you must add all the numbers and divide by the # of numbers in the set.
8+12+13+14+14+15 = 76
76/6 ≈ 12.7
To find the median you have to order the numbers from least to greatest, the middle number should be the median, but in this case two numbers are in the middle.
8, 12, 13, 14, 14, 15
So you have to add 14 and 13, which is 27.
Then divide by 2 which is ≈ 13.5
Answer:
7 1/15
Step-by-step explanation:
3 2/5 + 3 4/6 = 7 1/15
Answer:
The slope is -1
Step-by-step explanation:
It's decreasing which means it's negative and it decreases by 1 every time x increases by 1.
a/c = d/a
you would cross multiply to get aa = cd
aa = a^2
so you would have a^2 = cd
