Answer:

The solution is (2, -1) to show this by graphing do y = -1 by making a straight horizontal line at (0,-1) . And then for the other equation make a line where it starts at (0,4) and passes point (2,-1). Just plot those two points and connect them and you'll have made the line.

Answer:

C) 20.97 AED

Step-by-step explanation:

To find the expected value, E(X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as $\displaystyle E(X)=\mu=\sum xP(x)$ .

Here, x represents values of the random variable X, $P(x)$ represents the corresponding probability, and symbol $\displaystyle \sum$ represents the sum of all products $xP(x)$ . Here we use the symbol $\mu$ for the mean because it is a parameter. It represents the mean of a population.

In this case, the expected value of the ticket is $\displaystyle E(X)=\mu=\sum xP(x)=12(0.08)+18(0.15)+20(0.31)+22(0.08)+24(0.15)+25(0.23)=20.97$

This means that Ahmad can expect to win 20.97 AED for the ticket.

Solve log(3+2log(1+x)) =0

LUCKY_DIMON [66]

Assuming $\log x\equiv\log_{10}x$ ,

$\log(3+2\log(1+x))=0$
$10^{\log(3+2\log(1+x))}=10^0$
$3+2\log(1+x)=1$
$2\log(1+x)=-2$
$\log(1+x)=-1$
$10^{\log(1+x)}=10^{-1}$
$1+x=\dfrac1{10}$
$x=-\dfrac9{10}$

Answer:

12(x+2)

Step-by-step explanation:

Factor a 12 out of

12x + 24

12 goes into 12 once
