0.5a+8.75=13.25
We simplify the equation to the form, which is simple to understand
0.5a+8.75=13.25
We move all terms containing a to the left and all other terms to the right.
+ 0.5a=+13.25-8.75
We simplify left and right side of the equation.
+ 0.5a=+4.5
We divide both sides of the equation by 0.5 to get a.
a=9
Answer:
angle BDE=180°-152°
=28°

Answer:
a)



b) 0.75 = 75% probability that he makes no more than one of the shots
Step-by-step explanation:
We have these following probabilities:
64% = 0.64 probability that he misses both shots, that is, makes none of them.
11% = 0.11 probability that he makes one shot.
25% = 0.25 probability that he makes both shots.
a. Construct the appropriate probability distribution. (Round your answers to 2 decimal places.)
Binomial probability distribution, in which P(X = x) is the probability of making x shots. So



b. What is the probability that he makes no more than one of the shots? (Round your answer to 2 decimal places.)

0.75 = 75% probability that he makes no more than one of the shots
Answer:
36
Step-by-step explanation:
Number of boys = 30
also, Number of boys = 10(number of girls/2)
∴ 30 = 10(number of girls/2)
30×2 = 10(number of girls)
⇒ number of girls = 
⇒ number of girls = 6
Total number of girls and boys = 30 + 6 = 36
I would say that you cannot answer the question if you dont know either the X-value or Y-value. You need to know at least one of them to figure out the other.
