The equation is d + 3h = $13

The cost of each hamburger is $3.5

Solving an Equation

From the question, we are to write and solve the equation for the problem.

From the given information,

Danie purchases one hot dog $2.50

and

3 hamburgers

and

He spent $13 total

Let d represent hot dog

and

h represent hamburger

Then,

d = $2.50

We can write that

d + 3h = $13

$2.50 + 3h = $13

3h = $13 - $2.50

3h = $10.5

h = $10.5/3

h = $3.5

Hence, the cost of each hamburger is $3.5

which of the following equations represent a line that is parallel y=5x-4 ad passes through the point (3,4)

Answers

The equation that represents a line that is parallel to y = 5x - 4 and passes through the point (3, 4) is y = 5x - 11.

How to write the point-slope form equation?

We are given that

The slope of given line = 5And passed through point (3, 4)

Slope of parallel lines is the same, so slope of the line parallel to the given line will be m = 5

We have the slope and a point, using the point-slope form we can write the equation of the line:

\(\rightarrow\text{y} - 4 =5 \ (\text{x} - 3)\)

\(\rightarrow\text{y} = 5\text{x} - 15 + 4\)

\(\rightarrow\bold{y = 5x - 11}\)

Hence, the equation that represents a line that is parallel to y = 5x - 4 and passes through the point (3, 4) is y = 5x - 11.

A television station shows commercials for 7 1/2 minutes each hour how many 45 second commercials can it show per hour

Answers

the television station can show 10 45-second commercials per hour.

convert hour into minute

To convert hours into minutes, you simply multiply the number of hours by 60, since there are 60 minutes in an hour.

So, if you want to convert 3 hours into minutes, you would do:

3 hours x 60 minutes/hour = 180 minutes

Therefore, 3 hours is equivalent to 180 minutes.

There are 60 minutes in an hour, and 7 1/2 minutes is equal to 7.5 minutes.

So, the television station shows commercials for 7.5 minutes per hour.

We can convert 45 seconds to minutes by dividing it by 60:

45 seconds ÷ 60 = 0.75 minutes

To find out how many 45-second commercials the television station can show per hour, we can divide the total number of minutes of commercials by the length of each commercial:

7.5 minutes ÷ 0.75 minutes/commercial = 10 commercials

Therefore, the television station can show 10 45-second commercials per hour.

How to rewrite the quadratic equation?

We want to rewrite the quadratic equation into the vertex form, to do so, we just need to complete squares.

Here we start with:

x² - 2x - 4

Remember the perfect square trinomial:

Using that, we can rewrite our equation as:

Hans checked the temperature in his apple orchard at 10:00 P.M. His thermometer read

37. F. Hans kept checking his thermometer every hour for the next 8 hours and got these

readings: 37', 35, 33°, 32, 30°, 30°, 29., 30'. What was the median temperature

during this 8 hour period?

degrees

Answers

The median temperature during the 8-hour period in Hans' apple orchard was 32.5 degrees.

To find the median temperature during the 8-hour period, we first need to arrange the temperatures in ascending order: 29., 30', 30°, 30°, 32°, 33°, 35°, 37°.

The median temperature is the middle value in the ordered list. In this case, since there are an even number of values, we take the average of the two middle values:

(32° + 33°) / 2 = 32.5°

Therefore, the median temperature during the 8 hour period is 32.5 degrees.

It's important to note that temperature is a crucial factor for growing apple trees, as it can greatly impact the growth and health of the orchard. Temperatures below freezing can damage the fruit and buds, while excessively high temperatures can cause sunburn and stress on the trees. Monitoring the temperature regularly can help farmers make informed decisions about protecting their crops and maintaining the health of their orchards.

v/22 - 0.1 = 7.4 what is v?

Answers

Answer:

v = 165

Step-by-step explanation:

v/22 -0.1 = 7.4

v/22 = 7.4+0.1 =7.5

v = 7.5*22

v = 165

Answer:

\(v = 165\)

Step by step Explanations:

1) Add 0.1 to both sides.

\( \frac{v}{22} = 7.4 + 0.1\)

2) Simplify 7.4 + 0.1 to 7.5.

\( \frac{v}{22} = 7.5\)

3) Multiply both sides by 22.

\(v = 7.5 \times 22\)

4) Simplify 7.4 × 22 to 165.

\(v = 165\)

The best way to describe the location of a sample mean in a sampling distribution would be using the standard error. The standard error is a measure of the variability of the sample mean from sample to sample, and it takes into account both the sample size and the standard deviation of the population.

The sample standard deviation is a measure of the variability within the sample, but it does not provide information about the location of the sample mean in relation to the population mean. The difference between the population mean and the sample mean is a measure of bias, but it does not provide information about the variability of the sample mean.

Answers

The standard deviation of the given sample data is 55.7, the standard deviation is a measure of how spread out the values in a data set are.

It is calculated by taking the square root of the variance. The variance is calculated by taking the average of the squared differences between each value in the data set and the mean.

In this case, the mean of the data set is 177.67. The variance is 3123.53. The standard deviation is the square root of 3123.53, which is 55.7.

Here is a step-by-step calculation of the standard deviation:

Calculate the mean:

mean = (184 + 169 + 120 + 271 + 230 + 114 + 163 + 241 + 110) / 9 = 177.67

Calculate the squared differences between each value in the data set and the mean:

(184 - 177.67)^2 = 32.49

(169 - 177.67)^2 = 4.84

(120 - 177.67)^2 = 240.96

(271 - 177.67)^2 = 554.89

(230 - 177.67)^2 = 190.49

(114 - 177.67)^2 = 343.69

(163 - 177.67)^2 = 23.04

(241 - 177.67)^2 = 242.25

(110 - 177.67)^2 = 359.29

Calculate the variance:

variance = (32.49 + 4.84 + 240.96 + 554.89 + 190.49 + 343.69 + 23.04 + 242.25 + 359.29) / 9 = 3123.53

Calculate the standard deviation:

What is the angle between the vector 3–√i j3i j and the positive x-axis?

Answers

The angle between the vector (3 - √2)i + 3j and the positive x-axis can be determined using trigonometry.

To find the angle between the vector and the positive x-axis, we can use the arctan function. The angle can be calculated by taking the arctan of the y-component divided by the x-component of the vector.

In this case, the vector is given as (3 - √2)i + 3j. The x-component is 3 - √2, and the y-component is 3. Using the arctan function, we can calculate the angle as arctan(3 / (3 - √2)).

By substituting the values into a calculator or using trigonometric identities, we can find the angle. It is important to note that the arctan function returns an angle in radians. If we want the result in degrees, we can convert it by multiplying the result by 180/π.
