Answer:

[tex](x,y) = (-1,1)[/tex]

Step-by-step explanation:

Given

[tex]y>-2x - 1[/tex]

[tex]y>x + 2[/tex]

Required

Solve graphically

See attachment for graph;

The black shade represents [tex]y>-2x - 1[/tex]

While the green, represents [tex]y>x + 2[/tex]

Next, determine the intersection points between the two lines

From the attached graph, we have:

[tex](x,y) = (-1,1)[/tex]

Hence, the solution is:[tex](-1,1)[/tex]

Volume = length x width x height

Volume = 1.4 x 1.3 x 3.5 = 6.37 cubic cm

Answer:

y=-2x+5

Step-by-step explanation:

Use the equation y=mx+b

We can find the b(y-intercept) by looking at the graph

The graph crosses the y-axis at (0,5)

We can look at the slope at the graph. We can see its down 4 over 2 so the slope is -2.

Plug that into the equation y=mx+b

y=-2x+5

Answer:

-2, 3

Step-by-step explanation:

We are given the following inequality:

[tex]x + 2 > 7[/tex]

Solving it, we have that its solution is:

[tex]x > 7 - 2[/tex]

[tex]x > 5[/tex]

So values of x of 5 and lower are counterexamples to this, which means that -2 and 3 are correct options to this question.

Answer:

x = 16

Step-by-step explanation:

First, find hypotenuse using 18 and 16.

Using Pythagorean theorem, it gives 24.08

now use it again with the hypotenuse and (36/2) = 18

This gives us x = 16

Answer: 30°

Step-by-step explanation:

we have to find the angle adjacent with the right angle. For this we use the (-).

At this point, I am guessing you know how to use SOH-CAH-TOA, for this one we use SOH so sin. If you have a calculator set it on degree mode, then plug it in as sin⁻₁(), we put it like that because the missing angle has the given number opposite and the hypotenuse. It solves it and now we get 30 for the answer. I dont know if that made sense, tell me if it didnt so I can explain it better.

Answer:

[tex]P(B) = 0.3[/tex]

Step-by-step explanation:

We use the following formula for Venn probabilities to solve this question.

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

P((AUB)') = 0.4

This means that:

[tex]P(A \cup B) = 1 - P(A \cup B)' = 1 - 0.4 = 0.6[/tex]

We also have that:

[tex]P(A) = 0.5, P(A \cap B) = 0.2[/tex]

What is P(B)?​

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

[tex]0.6 = 0.5 + P(B) - 0.2[/tex]

[tex]0.3 + P(B) = 0.6[/tex]

[tex]P(B) = 0.3[/tex]

Answer:

a. Their average weight is of 200 pounds.

b. 0.0875 = 8.75% probability that the maximum safe weight will be exceeded

c. 0.0002 = 0.02% probability that the maximum safe weight will be exceeded

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

a. If 60 people are riding the coaster, and their total weight is 12,000 pounds, what is their average weight?

12000/60 = 200 pounds

Their average weight is of 200 pounds.

b. If a random sample of 60 adult men ride the coaster, what is the probability that the maximum safe weight will be exceeded?

Men means that [tex]\mu = 189, \sigma = 63[/tex].

Sample of 60 means that [tex]n = 60, s = \frac{63}{\sqrt{60}} = 8.13[/tex]

Safe weight will be exceeded if the sample mean is above 200 pounds, which has probability of 1 subtracted by the pvalue of Z when X = 200. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{200 - 189}{8.13}[/tex]

[tex]Z = 1.35[/tex]

[tex]Z = 1.35[/tex] has a pvalue of 0.9115

1 - 0.9115 = 0.0875

0.0875 = 8.75% probability that the maximum safe weight will be exceeded.

c. If a random sample of 60 adult women ride the coaster, what is the probability that the maximum safe weight will be exceeded?

Women means that [tex]\mu = 165, \sigma = 76[/tex]

Sample of 60 means that [tex]n = 60, s = \frac{76}{\sqrt{60}} = 9.81[/tex]

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{200 - 165}{9.81}[/tex]

[tex]Z = 3.57[/tex]

[tex]Z = 3.57[/tex] has a pvalue of 0.9998

1 - 0.9998 = 0.0002

0.0002 = 0.02% probability that the maximum safe weight will be exceeded

Answer:

It is a decreasing function for 0 < b < 1.

Step-by-step explanation:

Logarithm function:

The logarithm function is given by:

[tex]F(x) = \log_{b}{(x)}[/tex]

The base b determines if the function increases or decreases.

For 0 < b < 1, the function decreases.

For b > 1, the function increases.

In this question:

By the definition above, it is a decreasing function for 0 < b < 1.
