<h2>Answer:</h2>

<h3>1)    \frac{1}{2}</h3><h3>3)   \frac{1}{6}</h3><h3>5)   \frac{2}{3}</h3><h3 /><h2>Step-by-Step Explanation:</h2><h3 />

1.<em> </em>Find the probability of rolling less than a four.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Outcomes lower than four</u> = 1, 2, 3

Then to answer it you need the probability in the form of a fraction.

\frac{3}{6} simplifies into \frac{1}{2}

2. Find the probability of rolling an even prime number.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Prime Numbers Through 1-6</u> = 2, 3, 5

<u>Even Prime numbers Through 1-6</u> = 2

So the probability in the form of a fraction.

<h3>\frac{1}{6}</h3><h3 />

3. Find the probability of rolling factors of 20.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Factors of 20 Through 1-6</u> = 1, 2, 4, 5

So probabilty in the form of a fraction.

\frac{4}{6} simplifies into \frac{2}{3}

It is advertised that the average braking distance for a small car traveling at 65 miles per hour equals 120 feet. A transportat
katrin2010 [14]

Answer: H_0:\mu=120

H_A:\mu\neq120

Step-by-step explanation:

Let \mu denotes the average braking distance for a population of small car.

Given : It is advertised that the average braking distance for a small car traveling at 65 miles per hour equals 120 feet.

i.e. \mu=120

Objective of test : Whether the statement made in the advertisement is false

i.e.  \mu\neq120

Since '=' signs is contained by Null hypothesis and alternative hypothesis is against it.

So the null and the alternative hypotheses for the test will be:

H_0:\mu=120

H_A:\mu\neq120

PLEASE HELP ME!
kotegsom [21]

Answer:

Bottom left graph

Step-by-step explanation:

We have to use what is called the zero-interval test [test point] in order to figure out which portion of the graph these inequalities share:

−2x + y ≤ 4 >> Original Standard Equation

+ 2x + 2x

_________

y ≤ 2x + 4 >> Slope-Intercept Equation

−2[0] + 0 ≤ 4

0 ≤ 4 ☑ [We shade the part of the graph that CONTAINS THE ORIGIN, which is the right side.]

\displaystyle y > x + 2 \\ \\ 0 ≯ 2[We shade the part of the graph that does not contain the origin, which is the left side.]

So, now that we got that all cleared up, we can tell that the graphs share a region in between each other and that they both have POSITIVE <em>RATE OF CHANGES</em> [<em>SLOPES</em>], therefore the bottom left graph matches what we want.

** By the way, you meant \displaystyle y > x + 2because this inequality in each graph is a <em>dashed</em><em> </em><em>line</em>. It is ALWAYS significant that you be very cautious about which inequalities to choose when graphing. Inequalities can really trip some people up, so once again, please be very careful.

I am joyous to assist you anytime.
