Answer:
The average score is equal to 88.5
Step-by-step explanation:
we know that
An average test score is the sum of all the scores on an assessment divided by the number of test-takers.
so
The sum is equal to
![Sum=[79+80+92+92+81+100+88+98+71+100+91+90]=1,062](https://tex.z-dn.net/?f=Sum%3D%5B79%2B80%2B92%2B92%2B81%2B100%2B88%2B98%2B71%2B100%2B91%2B90%5D%3D1%2C062)
The number of test-takers is n=12
The average score is equal to
substitute
Answer:
D. 0.884
Step-by-step explanation:
I calculated it logically
Answer:
9
Step-by-step explanation:
Simplifying
2y + -6 = 12
Reorder the terms:
-6 + 2y = 12
Solving
-6 + 2y = 12
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + 2y = 12 + 6
Combine like terms: -6 + 6 = 0
0 + 2y = 12 + 6
2y = 12 + 6
Combine like terms: 12 + 6 = 18
2y = 18
Divide each side by '2'.
y = 9
Simplifying
y = 9
Answer:
Solution given:
AB=3units
<B=45°
<C=63°
DF=3units
<E=63°
<F=45°
for congruence opposite corresponding angle or side should be equal
so
∆ABCis congruent to ∆DFE by A.A.S axiom
Similarly
its another name also be
∆BAC=~ ∆FDE
you got it.third one.
