Answer:
The value of y = 12
Step-by-step explanation:
<u>Points to remember </u>
In a rhombus the diagonals are bisect each other perpendicularly.
<u>To find the value of y</u>
From the figure we can see a rhombus. The <1 is a right angle.
m<1 = 90
Therefore, 8y - 6 = 90°
8y = 90 + 6
8y = 96
y = 86/8
y = 12
Therefore the value of y = 12
B is the answer darling haha youre welcome i don’t feel like explaining
Find miles per hour by dividing total miles by total time:
240 miles / 3 hours = 80 miles per hour.
Now multiply miles per hour by time:
80 miles per hour x 2 hours = 160 miles.
The answer is 160 miles.
Okay so the range is the largest number - the smallest number.
So 25 - 11 = 14
The Absolute Mean Deviation is going to be a bit harder to explain, just go with it.
So we first calculate the mean.
119 ÷ 7 = 17
Now we calculate the distance each value is from 17. (SEE ATTACHMENT)
What happens next is that you take those values that are the distance from 17 and you add those up and calculate the mean of that.
28 ÷ 7 = 4
The Absolute Mean Deviation is 4.
I'll figure out the bottom in a minute. But this is all I got for you so far.
