Liula [17]

Answer:

P(5)=0.238

P(x\geq 6)=0.478

P(x

Step-by-step explanation:

In this case we can calculate the probability using the binomial probability formula

P(X=x)=\frac{n!}{x!(n-x)!}*p^x*(1-p)^{n-x}

Where p is the probability of obtaining a "favorable outcome " x is the number of desired "favorable outcome " and n is the number of times the experiment is repeated. In this case n = 10 and p = 0.54.

(a) exactly​ five

This is:

x=5,\ n=10,\ p=0.54.

So:

P(X=5)=\frac{10!}{5!(10-5)!}*0.54^x*(1-0.54)^{10-5}

P(5)=0.238

(b) at least​ six

This is: x\geq 6,\ n=10,\ p=0.54.

P(x\geq 6)=P(6) + P(7)+P(8)+P(9) + P(10)

P(x\geq 6)=0.478

(c) less than four

This is: x< 4,\ n=10,\ p=0.54.

Vera_Pavlovna [14]

Answer:

The value of b is -42

Step-by-step explanation:

Parallel equations have identical or equal slopes. Given the form of the equation; y=5x+b and the point it passes through (8,-2) we determine the unknown value b by substituting x with 8 and y with -2. We solve the equation; -2 =5(8)+b to obtain b = -42
