Around half of the electricity used in the United States is powered by burning coal. The United States is a developed country with a high level of carbon emissions. Select TWO realistic actions that could help to provide energy for the United States and also help to lower carbon emissions.

A
Create more fossil fuels.

B
Build additional power plants.

C
Reduce the demand for energy.

D
Use renewable sources of energy.

E
Make products that are more efficient.

F
Develop technology to better harvest fossil fuels.

Answers

Answer 1

The two options would be to reduce the demand for energy and or use renewable sources of energy. Options C and D are correct.

How to reduce carbon emission

The burning of fossil fuels such as coal and crude oil-derived fuels generates a large amount of emissions.

In order to cut down on the emission, the demand for energy needs to be lowered by all means. In addition, instead of using fossil fuels, renewable sources of energy can be used.

Greenhouse gases such as carbon dioxide, oxides of sulfur, and water vapor are produced largely as by-products of burning fossil fuels. These gases form a layer in the atmosphere and trap reflected solar radiation.

By doing so, the increase the average annual temperature of the planet (global warming). The warming of the planet has several negative effects on the climate and the ecosystems as a whole.

Renewable sources of energy, on the other hand, have very little to no greenhouse gas emissions.

A police officer claims that the proportion of drivers wearing a seat belt in a certain area is less than 40%.
To test this claim, the officer collects a random sample of 80 drivers and monitors if the driver was wearing a seat belt.
From this sample of 80 drivers, the police offers observes that 34 were wearing seat belts.
Assume the conditions needed to conduct a one sample proportion test are satisfied.
The setup for the null and alternative hypothesis is as follows:
H : p = 0.40; H, :p < 0.40, which is a left-tailed test.
Compute the test statistic and p-value for this Hypothesis test using Excel and round your answers to 3 decimal places.

Answers

Answer:

0.456

0.324

Explanation:

The null and alternative hypothesis :

H0 : p = 0.40; HA :p < 0.40

Test statistic :

(Ph - P) / sqrt[(p*(1-p))/n]

Ph = X / n

X = 34 ; n = sample size = 80

Ph = 34 / 80 = 0.425

(0.425 - 0.4) / sqrt[(0.4(0.6)) / 80]

0.025 / sqrt(0.003)

0.025 / 0.0547722

Test statistic = 0.4564359

Test statistic = 0.456

Using the P-value from Zscore calculator :

Significance level of 95% ; one tailed

Z statistic value = 0.456

P value = 0.324195

= 0.324 ( 3 decimal places)

B. The probability of a time from 25 seconds to 150 seconds
C. The probability of a time from 150 seconds to 250 seconds
D. The probability of a time from 75 seconds to 250 seconds
SUBMIT

Answers

A. The probability of a time from 75 seconds to 150 seconds.

A density graph shows the distribution of data over a range of values. The height of the graph at any point on the x-axis represents the density or frequency of data points at that point. Therefore, to find the probability of a certain range of values, you need to look at the area under the graph between those values. In this case, the density graph covers the range from 50 seconds to 200 seconds, so option A is the correct answer because it falls within that range. Options B, C, and D are outside of the range covered by the density graph, so they cannot be determined from the graph.

A density graph for all of the possible times from 50 seconds to 200 seconds can be used to find A. The probability of a time from 75 seconds to 150 seconds

How to solve

A density graph for all of the possible times from 50 seconds to 200 seconds can be used to find the probability of a time from 75 seconds to 150 seconds (Option A).

With this in mind, it can be seen that the correct answer and the reasons why the other answers are incorrect are given below:

It cannot be used to find the probability of a time from 25 seconds to 150 seconds (Option B), the probability of a time from 150 seconds to 250 seconds (Option C), or the probability of a time from 75 seconds to 250 seconds (Option D).

A store clerk is paid $10.75/ hour and a store assistant manager is paid $16.25/ hour. How long would it take the store managerto make $500 or more than the store clerk? Round to the nearest hour. Show all work.

Answers

Clerk wages + 500 = manager wages
10.75x + 500 = 16.25
500 = 5.5x
x = 91 hours

Check:
10.75 * 91 = 978.25
16.25 * 91 = 1478.75
1478.75 - 978.25 = 500.5 :)

It will take approximately 91 hours for the store manager to make $500 or more than the store clerk.

If the store clerk is paid $10.75/ hour and the store assistant manager is paid $16.25/ hour, the difference in their pay per hour will be expressed as:

The difference in the amount earned per hour = 16.25 - 10.75

The difference in the amount earned per hour = $5.5

This means that the store assistant manager will collect $5.5 more than the store clerk in one hour. This can be expressed as:

$5.5 = 1 hour

To determine how long it will take the store manager to make $500 or more than the store clerk, we can write:

$500 = x

Divide both expressions:

[tex]\dfrac{5.5}{500} =\dfrac{1}{x} \\Cross \ multiply\\5.5x = 500 \times 1\\5.5x = 500\\x=\frac{500}{5.5}\\x= 90.9 \ hours[/tex]

This means that it will take approximately 91 hours for the store manager to make $500 or more than the store clerk.

What is probability?

Probability deals with the likelihood of an event or phenomena occurring and is quantified as a number between 0 and 1 inclusive, where 0 indicates an impossible chance of occurrence and 1 denotes the certain outcome of an event. Joint probability refers to a statistical measure that determines the probability of two events occurring together and at the same point in time.

Joint probability is the probability of event Y occurring at the same time that event X occurs. Hence, joint probability is a measure of two events happening at the same time and can only be applied to situations where more than one observation can occur at the same time.  Mathematically, it is given by P (A and B) = P(A) * P(B) As in the given situation, the probability estimated is the probability to two events that iPhone is defective and it is manufactured by company A occurring at the same time, it is a joint probability.

The length of CE is 3.6 and the radius of the circle is 2

The length of CE

Start by calculating the length of AD using:

AD^2 = AC^2 - CD^2

This gives

AD^2 = 10^2 - 6^2

AD^2 = 64

Take the square roots

AD = 8

Represent CE with x.

So:

AE = 10 - x

Calculate ED using:

ED^2 = CD^2 - CE^2

ED^2 = AD^2 - AE^2

So, we have:

AD^2 - AE^2 = CD^2 - CE^2

This gives

8^2 - (10 - x)^2 = 6^2 - x^2

Expand

64 - 100 + 20x - x^2 = 36 - x^2

Add x^2 to both sides

64 - 100 + 20x  = 36

Evaluate the like terms

20x = 72

Divide by 20

x = 3.6

Hence, the length of CE is 3.6

The radius of the circle

The equation is given as:

x^2 + y^2 + 6x + 5y = -45/4

Rewrite as:

x^2 + 6x + y^2  + 5y = -45/4

Take the coefficients of x and y

Divide them by 2, square the result and add the result to both sides.

So, we have:

x^2 + 6x + (6/2)^2 + y^2  + 5y + (5/2)^2= -45/4+ (6/2)^2 + (5/2)^2

This gives

x^2 + 6x + (6/2)^2 + y^2  + 5y + (5/2)^2= 4

Express as perfect squares

(x + 3)^2 + (y + 5/2)^2 = 4

The circle equation is represented as:

(x - a)^2 + (y - b)^2 = r^2

Where r represents the radius

By comparison, we have:

r^2 = 4

This gives

r = 2

Hence, the radius of the circle is 2
