-(2x+1)(3x+4)
It’s just a guess??
The answer is :
0.18181818
But you can also write it like this
When finding if a set is a function, the best method is looking at the x coordinates. Make sure that the if the x coordinates repeats that the y coordinates are identical, meaning if a point repeats; (2,0) and (2,0). If the x coordinates repeats itself but has two different y coordinates, it is not a function: (2,0) and (2,6).
A. x=0 repeats with two different y coordinates, NOT FUNCTION
B. No x's repeat, FUNCTION
C. x=2 repeats with two different y coordinates, NOT FUNCTION
D. x=6 repeats with two different y coordinates, NOT FUNCTION
Answer: 0.1318
Step-by-step explanation:
Given : The proportion of college students were very confident that their major will lead to a good job : p= 0.56
Let x be the binomial variable (for success) that represents the number of college students were very confident that their major will lead to a good job.
with parameter p = 0.56 n= 20
Using binomial , we have

Required probability :-

Hence, the probability that 13 of them were very confident their major would lead to a good job =0.1318
