A=90 degrees divide by 5
=18 degrees
2c+a=90
2c+18=90
2c=90-18
2c=72
divide each side by 2
c=36
therefore:
2c=72
b=4a+c
b=4(18)+36
b=72+36
b=108
Answer:
μ =2.23


Step-by-step explanation:
Radio(x) weeks P(x)
0 5 5/100 = 0.05
1 27 27/100=0.27
2 27 27/100 = 0.27
3 27 27/100 = 0.27
4 9 9/100=0.09
5 5 5/100=0.05
We know that
Mean ,μ

μ = 0 x 0.05 + 1 x 0.27 + 2 x 0.27 + 3 x 0.27 + 4 x 0 .09 + 5 x 0.05
μ =2.23





Answer:
A is 157 B is 157 and F is 42
Step-by-step explanation:
i am not 100% sure but i am like 80% sure
Option C:
The value of m is 4.
Solution:
Given data:
AB = 4m – 15
BC = 5m –6
AC = 15
<u>To find the value of m:</u>
Using segment addition postulate,
AB + BC = AC
4m – 15 + 5m –6 = 15
Arrange the like terms together.
4m + 5m – 15 – 6 = 15
9m – 21 = 15
Add 21 on both sides of the equation,
9m = 36
Divide by 9 on both sides of the equation.
m = 4
The value of m is 4.
Option C is the correct answer.
You have to dividers then multiply then add then subtracts the 2 from the r
