If you have tickmarks on the segment, on a blank piece of paper, then you count out the spaces to get the length of the segment. This is assuming the tickmarks are properly spaced out. If there aren't any tickmarks, then you'll have to use a ruler to find the length. Either way, a ruler is encouraged.
The coordinate plane makes things easier to find the length of any segment. Use either the pythagorean theorem or the distance formula to find the length of the segment.
Answer:
<h3>
y = 20</h3><h3 />
Step-by-step explanation:
line RPN = 180 = 4y - 10 + 90 + y
180 - 90 + 10= 5y
100 = 5y
y = 100/5
y = 20
Answer
x = 7.5
Explanation
This is a case of similar triangles.
Similar triangles have bigger triangles which have sides which are multiples of smaller triangles sides.
We know that the adjacent side of the bigger triangle is 6 and for the smaller triangle it’s 4 so the constant factor by which the sides of the small triangle are multiplied to obtain the sides of the large triangle is
6/4 = 3/2
Since we know the hypotenuse of the smaller triangle is 5.
Multiply this by 3/2 to get the hypotenuse of the bigger triangle
3/2 • 5 = 7.5

The mean of this discrete random variable is 7.96
<em><u>Solution:</u></em>
Given that,
x 4 6 9 11 15
P(x) 0.20 0.34 0.15 0.22 0.09
<u><em>Mean is given as:</em></u>
![\mu_{x}=\sum[x \times P(x)]](https://tex.z-dn.net/?f=%5Cmu_%7Bx%7D%3D%5Csum%5Bx%20%5Ctimes%20P%28x%29%5D)
Therefore,
Thus, mean of this discrete random variable is 7.96
