How to solve? im doing piecewise functions
Novosadov [1.4K]

If

g(x) = \begin{cases} -x + 4 & \text{if } x \le -1 \\ 3 & \text{if } -1

then by this definition,

g(0) = 3 … … … (since -1 < 0 < 2)

and

g(1) = 3 … … … (also because -1 < 1 < 2)

A telemarketing company calls telephone numbers chosen at random. It finds that 70% of calls arc not completed (the party does n
saw5 [17]

Answer:

We conclude that the 8 % of calls result in a sale.

We conclude that the 5.3% of sales are made to women.

Step-by-step explanation:

We know  that 70% of calls arc not completed (the party does not answer or refuses to talk), that 20% result in talking to a woman, and that 10% result in talking to a man.  After that point, 30% of the women and 20% of the men actually buy something.

We calculate what percentage of calls result in a sale, and we get:

p=\frac{20}{100}\cdot \frac{30}{100}+\frac{10}{100}\cdot \frac{20}{100}\\\\p=\frac{6}{100}+\frac{2}{100}\\\\p=\frac{8}{100}

We conclude that the 8 % of calls result in a sale.

We know that the ratio of women to men talking on the telephone is 2:1.

We calculate a percent of sales are made to women, and we get:

w=\frac{2}{3}\cdot 8\\\\w=\frac{16}{3}\\\\w=5.3

We conclude that the 5.3% of sales are made to women.

Simplify.<br> -3(u + 3) + 4(4u + 2)
sergeinik [125]

Hello!

So, here you want to do the distributive property.

Start on the left side of the + sign...

-3*u = -3u

-3*3 = -9

So we now we have:

(-3u + -9) + 4(4u + 2)

Now we focus on the right side of the + sign...

4*4u=16u

4*2=8

So now we have:

(-3u + -9) + (16u + 8)

Now you want to combine like terms. Start by adding terms with the same variable. So, we need to add -3u and 16u

<em>-3u + 16u =</em> 13u

Now we have:

13u + -9 + 8

Now add the constants, -9 + 8

-9 + 8 = -1

So, the simplified expression would be:

13u - 1 or 13u + -1
