Answer:
The probability is 0.9106
Step-by-step explanation:
The variable that says the number of defective toasters follows a binomial distribution, where we have n identical and independent events (50 toasters) with a probability p of success (1% are defective) and a probability 1-p of fail (99% are not defective). So the probability that x toasters from the 50 are defective is:
Then, the probability P that no more than one of these toasters is defective is:
P = P(0) + P(1)
So, P(0) and P(1) are calculated as:
Finally, P is equal to:
P = 0.6050 + 0.3056 = 0.9106
Question 1 would be 4 divided by 1/3 (A)
Question 2 would be 16 (A)
Question 3 would be 48 (B)
Question 4 would be 60 laps
Question 5 would be 1/15th
Hope this helps!! :D
Answer:
x = 1
y = -2
Step-by-step explanation:
5x - 2y = 9 -----------(I)
2x + 7y = -12 --------------(II)
Multiply (I) by 7 35x - 14y = 63
Multiply (II) by 2 <u>4x + 14y = - 24</u><u> </u> {Now add and thus y will be eliminated}
39x = 39
x = 39/39
x = 1
Plugin x = 1 in equation(I)
5*1 - 2y = 9
5 -2y = 9
-2y = 9 -5
-2y = 4
y = 4/-2
y = -2
Just borrow from the 7 and take the 1 to the 2 and that will make it as 12 so then you subtract 12 - 4 and the answer will be 1,180
