Answer:

11.25

Step-by-step explanation:

The slope is [tex]\frac{3}{4}[/tex]

Using this we can find Δx and Δy.

The slope is Δy/Δx

And Δx is 15 since the number of units from 12 to 27 is 15.

So Δy/15 = [tex]\frac{3}{4}[/tex]

Multiply so they have common denominators.

4Δy/60 = [tex]\frac{45}{60}[/tex]

Multiply each side by 60 and solve.

4Δy = 45

Δy = 11.25

So the length of x is 11.25

Multiplying both sides by 100 and dividing both sides by 70,

we have x = 14 ×  100 /70

x = 20

If you are using a calculator, simply enter 14×100÷70, which will give you the answer.

The 99% confidence interval for the mean number of jobs held by the retired men in the study is approximately 6.3 < μ < 8.1

To calculate the 99% confidence interval, we need the sample mean, the population standard deviation, the square root of the sample size, and the z-value associated to a 99% confidence. In this case, we know the following:

The confidence interval formula is given by the following equation:

x-bar ± z * (σ/√n)

Subbing the values into the equation, we get:

7.2 ± 2.57 * (2.1/√50)

The 99% confidence interval would therefore be approximately 6.3 < μ < 8.1

Answer:

c = 11/4

Step-by-step explanation:

One way of doing this is to let 2c = x.  Then our equation becomes

2x + x = 2x + 11/2, or x = 11/2.

But 11/2 = 2c.  Thus, c = 11/4

Answer:

They can't occur together because independent means by itself.

Step-by-step explanation:

The correct answer is D) A's occurrence cannot affect the probability of B's occurrence. This reflects the defining characteristic of independent events in probability, where the occurrence of one event does not influence the likelihood of another.

If events A and B are independent, then this means that the occurrence of event A does not affect the probability of event B occurring, and vice versa. This is a fundamental concept in the study of probability which distinguishes independent events from dependent or mutually exclusive events.

Among the options provided, the correct choice is D) A's occurrence cannot affect the probability of B's occurrence. Independent events have no influence on each other, meaning that if you know event A has happened, this knowledge does not change the likelihood of event B happening, and conditional probability does not apply here.

On the other hand, mutually exclusive events cannot occur together. If A and B were mutually exclusive, then the probability of both A and B occurring at the same time would be zero. This is not the case with independent events, where the probability of A and B occurring is simply the product of their individual probabilities if the events are occurring simultaneously.

Angle L is 67.5 degrees. Angles F and L are opposite each other, yet the same angle-degree. Hope this helps <3

Angle L is 67.5 degrees. Angles F and L are opposite each other, yet the same angle degree.

Alternate interior angles are formed when a transversal passes through two lines.

The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.

In the figure,we can see that ∠F and ∠L are alternate interior angles.

So the angles are ∠F=∠L=67.5

Hence Angle L is 67.5 degrees. Angles F and L are opposite each other, yet the same angle degree.

Answer:

26 of each

Step-by-step explanation:

To solve write this as an equation (35x)+(15x)=1300

For this case we have:

x: Variable representing the types of advance input

y: Variable representing the same-day entry types

We have according to the cost:

[tex]35x + 15y=1300[/tex]

According to the number of tickets:

[tex]x + y = 60[/tex]

We have a system of two equations with two unknowns:

[tex]35x + 15y = 1300\\x + y = 60[/tex]

We multiply the second equation by -35:

[tex]35x + 15y = 1300\\-35x-35y = -2100[/tex]

We add:

[tex]-20y = -800\\y = \frac {800} {20}\\y = 40.[/tex]

Thus, 40 same-day tickets were sold.

[tex]x + 40 = 60\\x = 60-40\\x = 20[/tex]

20 advance tickets were sold

Answer:

20 advance

Andre saves more money than Elena after four weeks and after 6 weeks the savings of Andre and Elena is the same and this can be determined by forming the linear equation.

Given :

Let w represents the total number of weeks. So, the linear equation that represents the situatuion "Andre starts with $100 in his savings account and adds $5 per week" is:

S = 5w + 100

The linear equation that represents the situatuion "Elena starts with $10 in her savings account and adds $20 each week" is:

S' = 20w + 10

a) After four weeks the savings of Andre is given by:

S = 5(4) + 100

S = 20 + 100

S = $120

After four weeks the savings of Elena is given by:

S' = 20(4) + 10

S' = 80 + 10

S' = $90

So, Andre saves more money than Elena after four weeks.

b) Now, the number of weeks after which the savings of Andre and Elena are the same is:

5w + 100 = 20w + 10

Simplify the above equation in order to determine the value of 'w'.

90 = 15w

w = 6

So, after 6 weeks the savings of Andre and Elena is the same.

Answer:

Box=0.95

Orange bag=0.44

Package=0.44

Step-by-step explanation:

Divide the cost by the amount of whatever. For ex. The 3.79/4 because there are 4 boxes.

Final answer:

The unit rate for a box of 4 light bulbs is $0.95 per bulb, for a bag of 5 oranges it's $0.44 per orange, and for a package of 12 bars of soap, the unit rate is $0.44 per bar.

Explanation:

To calculate the unit rate for each item, you divide the total cost by the number of items in the package. This tells you the cost per single item. Let's calculate the unit rates, rounding to the nearest cent.

Remember, when working with prices, it's standard practice to round to the nearest cent, which represents the smallest unit of currency used in transactions.

The sum of any number and its opposite is 0

Step-by-step explanation:

It is given an expression,

8.29 * (-5.62 + 5.62)/5.62

To find the correct reason

Here - 5.62 + 5.62 = 0

5.62 is opposite to - 5.62

because sum of a number and its opposite is 0.

Therefore the correct answer is third option.

The sum of any number and its opposite is 0

Answer:

The sum of any number and it's opposite is 0.

Step-by-step explanation:

Given expression is [tex]8.29\cdot\frac{-5.62+5.62}{5.62}[/tex]

Now we need to find the reason about why the given expression equals to 0.

If you look at the numerator carefully then you will find that numerator contains two terms -5.62 and +5.62 which are exactly same and opposite in sign. So they will cancel each other and give result 0.

After that we get only multiplication and division operation and we know that multiplication by 0 gives 0. that's why the final answer is 0.

So the correct choice is "The sum of any number and it's opposite is 0."

Answer:

Choosing the "best" measure of center. Mean and median both try to measure the "central tendency" in a data set. The goal of each is to get an idea of a "typical" value in the data set. The mean is commonly used, but sometimes the median is preferred.

Step-by-step explanation:

Final answer:

To compare data sets, one must consider whether to use the mean or the median. The mean is suitable for symmetric, outlier-free distributions, while the median is better for skewed data or data with outliers.

Explanation:

Comparing Data Sets Using Measures of Center

When comparing data sets to understand the center, it's crucial to choose the most appropriate measure of center. The mean and the median are the two most common measures. The mean, which is the sum of all values divided by the number of values, is a great indicator of the center for symmetric distributions without outliers. In contrast, the median, which is the middle value in an ordered list, is robust to outliers and is better for skewed distributions.

To determine which measure to use, consider whether the data contain outliers or extreme values that could heavily influence the mean. If so, the median would be a better representation of the center. Moreover, the shape of the data set (symmetrical vs. skewed) and the presence of outliers or extreme values are crucial considerations. The median appears more suitable for skewed data sets, while the mean could be a more accurate measure for symmetric, outlier-free data.

For the single value of x, the value of y will be single. Then option C does not represent a function.

A statement, principle, or policy that creates the link between two variables is known as a function

We know that the value of x must be different.

For the single value of x, the value of y will be single.
