Answer: B. 9/25
Work Shown:
x% = x/100
36% = 36/100
36% = (9*4)/(25*4)
36% = 9/25
Using your calculator, you should find that 9/25 = 0.36 which converts to 36%, so that helps confirm the answer.
B equals c hope this helps :)
Answer: 0.01145
Step-by-step explanation:
We use Binomial distribution , where the probability of getting x successes in n trial is given by :-
, p = probability of getting each success in each trial.
As per given
The proportion that a car with a certain protection system will be recovered= p=0.87
n= 8
Let x be the number of cars will be recovered.
Then, the probability that 4 of 8 stolen cars will be recovered:


Hence, the required probability is 0.01145.
A: x= 2.5
b: y= 12.9
c: z= 12
d: w= 2.75
e: t= 4
(Lemme know if it’s wrong)
Answer:
y=-2x+b
Step-by-step explanation:
Just use the formula y=ax+b, and input -2 as A, and 3, as x, and 2, as y, and then simplify.
