Factor yz + 6 + y +6z.<br> z + 1)(y + 6)<br> (z - 1)(y + 6)<br> (z + 6)(y - 1)
Sedbober [7]
The answer is the first one: (z+1)(y+6).

Explanation:

yz + 6 + y + 6z

= yz + y + 6 + 6z

= y(z+1) + 6(1+z)

= (z+1)(y+6)

For (z+1), you can also write (1+z), it doesn’t matter.

Hope it helps!

In a valid probability distribution, each probability must be between 0 and 1, inclusive, and the probabilities must add up to 1
lora16 [44]

The value of x is 1/5

Step-by-step explanation:

In a probability distribution, probability should be between 0  and 1. The probabilities add up to one.

Given probabilities are:

\frac{1}{10}, \frac{1}{5}, \frac{1}{2}, x

The sum of these probabilities will be equal to 1.

So,

To find x,

\frac{1}{10}+\frac{1}{5}+\frac{1}{2}+x = 1\\\frac{1+2+5}{10}+x=1\\\frac{8}{10}+x=1\\x= 1- \frac{8}{10}\\x = 1- \frac{4}{5}\\x= \frac{5-4}{5}\\x=\frac{1}{5}

The value of x is 1/5
