Answer:
8.48
Step-by-step explanation:
add all the angles and make them equal to 360
88 + 108 + (3x-6) + 2x = 360
196 + 5x -6 = 360
190 + 5x = 360
5x = 170
x = 34 = answer
Answer 2 and 1/2 plotted 2 times 1 and 1/2 one time
2 and 3/4 four times 3 and 3/4 once 3 and 1/2 twice and 3 twice. Step-by-step explanation:
Answer:
0+6=6
Step-by-step explanation:
2x if x=0 would = 2x0=0 and 3y if y=2 3x2=6 so 0+6=6
Answer: n= 15
p= 0.30
Step-by-step explanation:
Binomial distribution :
Let x be a binomial variable.
The probability of getting success in x trials is given by :-
, where n is the total number of trials and p is the probability of getting success in each trail.
Given : The proportion of parolees from prison return to prison within 3 years= 0.30
We assume that whether or not one prisoner returns to prison is independent of whether any of the others return to prison.
⇒ p =0.30
Let the random variable X be the number of parolees out of 15 that return to prison within 3 years.
⇒ n= 15
