Answer:
The probability is 0.057797
Step-by-step explanation:
Consider the provided information.
It is given that true percentage of voters who vote for the proposition is 63%,
Let p is probability of success.
According to the binomial distribution:
![P(x;p,n)=^nC_x(p)^x(1-p)^{(n-x)}](https://tex.z-dn.net/?f=P%28x%3Bp%2Cn%29%3D%5EnC_x%28p%29%5Ex%281-p%29%5E%7B%28n-x%29%7D)
Substitute n=7, p=0.63 and x=2 in the above formula.
![P(x;p,n)=^7C_2(0.63)^2(1-0.63)^{(7-2)}](https://tex.z-dn.net/?f=P%28x%3Bp%2Cn%29%3D%5E7C_2%280.63%29%5E2%281-0.63%29%5E%7B%287-2%29%7D)
![P(x;p,n)=\frac{7!}{2!5!}(0.3969)(0.37)^{5}\\P(x;p,n)=21(0.3969)(0.37)^{5}\\P(x;p,n)=0.0577974947199\\P(x;p,n)\approx0.057797](https://tex.z-dn.net/?f=P%28x%3Bp%2Cn%29%3D%5Cfrac%7B7%21%7D%7B2%215%21%7D%280.3969%29%280.37%29%5E%7B5%7D%5C%5CP%28x%3Bp%2Cn%29%3D21%280.3969%29%280.37%29%5E%7B5%7D%5C%5CP%28x%3Bp%2Cn%29%3D0.0577974947199%5C%5CP%28x%3Bp%2Cn%29%5Capprox0.057797)
Hence, the probability is 0.057797
To find if one is a function, you must see if the pattern is the same.
Domains (x) can not have two values
I forget what the y value is called, but there can be the same y- value for multiple x - values
A. is not a function, because its ordered pairs are all over the place, and the value 4 in the x - value has two values assigned - 0 and 3, which makes it invalid.
B. may be a linear function. Its ordered pairs aren't jumping all over the place.
Both the x and y go up one for one, so the function could be y = x + 3
C. isn't because the x - value 2 has two values. Again, that makes this invalid.
D. is invalid because there is two x - values for 2.
Therefore, the answer is B.
35+5(4-s)=2550
35+20-5s=2550
55-5s=2550
-55 -55
-5s = 2495
s = - 499
-499 + a = 4
+499 +499
a = 503
