A simple way to solve fraction divided by while number problems is to multiply the denominator and the whole number together, but that only works if the numerator is 1, which in this case, they were all in fact, 1s.

Suppose that the probabilities of a customer purchasing​ 0, 1, or 2 books at a book store are 0.20.2​, 0.30.3​, and 0.50.5​, res
PIT_PIT [208]

Answer:

0.78

Step-by-step explanation:

We have the next probability distribution:

X            P(X)

0            0.2

1             0.3

2            0.5

As we can see when we add all the probabilites the result is 1. Now calculating the mean we have:

mean=\mu=(0\times0.2)+(1\times 0.3)+(2\times 0.5)=0+0.3+1=1.3

The standard deviation is:

\sigma=\sqrt{\sum(x-\mu)^{2}(P(x))}

Then using the data that we have:

\sigma=\sqrt{\sum(x-\mu)^{2}(P(x))}\\\sigma=\sqrt{(0-1.3)^{2}(0.2)+(1-1.3)^{2}(0.3)+(2-1.3)^{2}(0.5)}\\\\\sigma=\sqrt{(-1.3)^{2}(0.2)+(-0.3)^{2}(0.3)+(0.7)^{2}(0.5)}\\\\\sigma=\sqrt{(1.69)(0.2)+(0.09)(0.3)+(0.49)(0.5)}\\\\\sigma=\sqrt{0.338+0.027+0.245}\\\\\sigma=\sqrt{0.61}\\\\\sigma=0.78\\

Then the standard deviation is 0.78

How many solutions are there to the equation below?
Pepsi [2]

Answer:

C

Step-by-step explanation:

This is a linear equation in one variable and has 1 solution

12x + 6 = 5x ( subtract 5x from both sides )

7x + 6 = 0 ( subtract 6 from both sides )

7x = - 6 ( divide both sides by 7 )

x = - \frac{6}{7} ← 1 solution
