One way to put 7 and 8 on a number line is by putting 7 and 8 on a number line. Hope this helps.

(f•g)(x) = -3(2x-6) -4
= -6x + 14

f•g(-7) = -6(-7) + 14 = 56

In an experiment, a number cube is rolled 4 times. The number of times a 5 shows is recorded. Sixty trials of the experiment are

WARRIOR [948]

Using the probability concept, the distribution is given as follows:

P(X = 0) = 0.1.

P(X = 1) = 0.15.

P(X = 2) = 0.55.

P(X = 3) = 0.15.

P(X = 4) = 0.05.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

The distribution gives the <u>probability of each outcome</u>.

In this problem, there were 60 trials, hence the distribution is given as follows:

P(X = 0) = 6/60 = 1/10 = 0.1.

P(X = 1) = 9/60 = 3/20 = 0.15.

P(X = 2) = 33/60 = 11/20 = 0.55.

P(X = 3) = 9/60 = 3/20 = 0.15.

P(X = 4) = 3/60 = 1/20 = 0.05.

Answer:

Follows are the answer to the given point.

Step-by-step explanation:

In point 1:

$\to P( \text{number of response}) = \frac{192}{338} \\$

$= \frac{96}{169}\\\\= 0.56$

In point 2:

$\to P| \text{(Zoloft and fill response)}| = \frac{27}{338}$

$= 0.079$

In point 3:

$\to P(\frac{\text{ full or partial}}{\text{St. John's Wort}}) = \frac{\frac{43}{338}}{\frac{113}{338}}$

$= \frac{43}{338} \times \frac{338} {113}\\\\= \frac{43}{113}\\\\= 0.38$

In point 4:

$\to P(\frac{\text{Placebo}}{\text{full or response}}) = P(\frac{(\text{Placebo} \cap \text{full or response})} {\text{p(full response)}})$

$= \frac{\frac{79}{338}}{ 1- \frac{91}{338}} \\\\ = \frac{\frac{79}{338}}{ \frac{338-91}{338}} \\\\ = \frac{\frac{79}{338}}{\frac{247}{338}} \\\\ = \frac{79}{338} \times \frac {338}{247} \\\\= \frac{79}{274} \\\\ = 0.28$
