Answer: 63 degrees.
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
Therefore: 54 + y + y = 180
So 54 + 2y = 180
So 2y = 126
Therefore y = 63 degrees.

Answer:
(a) 83% of the scores were at or below her score.
(b) 17% was above her score.
Step-by-step explanation:

To find:
a) Percentage of scores which were at or below her score?
b) Percentage of score which were above her score?

red marbles= 12
blue marbles= 10
sample size= 12+10
sample size= 22
Step two:
Required
Find the probability of the given event. (a) The marble is red
Let the probabiilty be P(R)
P(R)= 12/22
P(R)= 6/11
Answer:
No solutions
Step-by-step explanation:
4(-8x + 5) = -32x - 26
Expanding the parentheses:
-32x+20=-32x-26
Adding 32x to both sides:
20=-26
This equation has no solutions, because these two are not equal. Hope this helps!
