Answer:
The probability that 13 of them were very confident their major would lead to a good job is 1.08%.
Step-by-step explanation:
Given : A 2017 poll found that 56% of college students were very confident that their major will lead to a good job. If 15 college students are chosen at random.
To find : What's the probability that 13 of them were very confident their major would lead to a good job?
Solution :
Applying Binomial distribution,
Here, p is the success p=56%=0.56
q is the failure
n is the number of selection n=15
The probability that 13 of them were very confident their major would lead to a good job i.e. x=13
Substitute the values,
The probability that 13 of them were very confident their major would lead to a good job is 1.08%.
X\6=12\9
multiply both sides by 6
x=12\9 x 6
x=8
Answer:
-4.5 ¯\_(ツ)_/¯
Step-by-step explanation:
-4x+5=13
-4x=5+13
-4x=18
-4x/-4=18/-4
x=-4.5
Answer: 9 + 10 = 19
-129 x 5 = -645
232 exponent of 2 = 53,824
32 x 400 = 12,800
400 / 23 = 17
53,824 + 12,800 + -645 + 19 + 17 = 66015
