Answer:
A = 20 degree
B = 160 degree
C = 160 degree
D = 20 degree
Step-by-step explanation:
If the measure of angle C is eight timeseight times the measure of angle A
That means C = 8A
But According to the question, angles A and D have the same measure as well as angles C and B.
That is, B = 8A and D = A
If A + B + C + D = 360
Let us substitute for B, C and D
A + 8A + 8A + A = 360
18A = 360
A = 360/18 = 20
Therefore
A = 20 degree
B = 8 × 20 = 160 degree
C = 8× 20 = 160 degree
D = 20 degree
Answer:
0.36
Step-by-step explanation:
Given that:
Mean = 70
Standard deviation = 5.5
score (x) = 72
Formular for obtaining Standardized score (Zscore) :
Zscore = [score (x) - mean] / standard deviation
Hence,
Zscore = (72 - 70) / 5.5
Zscore = 2/ 5.5
= 0.3636363
Zscore = 0.36 ( 2 decimal place)
Simplify the following:
(k^3 k^7)/3 - 5
Combine powers. (k^3 k^7)/3 = k^(7 + 3)/3:
k^(7 + 3)/3 - 5
7 + 3 = 10:
k^10/3 - 5
Put each term in k^10/3 - 5 over the common denominator 3: k^10/3 - 5 = k^10/3 - 15/3:
k^10/3 - 15/3
k^10/3 - 15/3 = (k^10 - 15)/3:
Answer: (k^10 - 15)/3
Answer:
It is a factor.
Step-by-step explanation:
its definitely a factor
rule: put (x-2)=0
so x = 2
now put this 2 in the equation as x
![2^{3} -4*2^{2}+3*2+2](https://tex.z-dn.net/?f=2%5E%7B3%7D%20-4%2A2%5E%7B2%7D%2B3%2A2%2B2)
which equals to 0, as a result its a factor
you can check the sum in the calculator by yourself
hope it helps.
