Can an absolute value function have an inverse function? If so, give an

Musya8 [376]

Answer:

Let f be a function. If any horizontal line intersects the graph of f more than once, then f does not have an inverse. An absolute value function (without domain restriction) has an inverse that is NOT a function. That's why an absolute value function does not have an inverse function。

Determine the number of times an outcome of 1, 3 or 8 is expected

First, calculate the theoretical probability of 1, 3, or 8

This is calculated as:

$Pr = P(1) + P(3) + P(8)$

The spinner is divided into 8 equal segments and each outcome appears once.

So, we have:

$Pr = \frac{1}{8}+\frac{1}{8}+\frac{1}{8}$

Take LCM and add

$Pr = \frac{1+1+1}{8}$

$Pr = \frac{3}{8}$

So, the expected number of times (E) is:

$E = Pr * n$

$E = \frac{3}{8} * 1060$

$E = \frac{3* 1060}{8}$

$E = \frac{3180}{8}$

$E = 397.5$

Approximate

$E = 398$

<em>This means about 400 times</em>

(b) we often read that iq scores for large populations are centered at 100. what percent of these 78 students have scores above

zheka24 [161]

Given that the<span> iq scores for large populations are centered at 100.

To get what percent of these 78 students have scores above 100 we conduct a normal distribution probability of the data.

P(x > 100) = P(z > (100 - 100)/sd) = P(z > 0) = 1 - P(z < 0) = 1 - 0.5 = 0.5 = 50%
