Answer: c

Step-by-step explanation:

The coordinates of the image of point (5, -2) under the same translation is (3, -4)

Translation is a type of transformation that moves a figure or a function in a specific direction and distance without rotating or changing its size.

To solve the given, you can use the equation below:

image = point + translation

So we can say:

translation = image - point

translation = (-2, 5) - (0, 7)

translation = (-2-(0) , 5-7)

translation = (-2, -2)

Under the same translation, the coordinates of the image of the point (5, -2) will be:

image = point + translation

image = (5, -2) + (-2, -2)

image = (5+(-2) , -2+(-2))

image = (3, -4)

The solution set to the given system of equation is -

x = 4 & y = 1.5.

Given is the system of linear equations as -.

- 5x + 6y = - 11

6y = x + 5

In mathematics, a system of linear equations is a collection of one or more linear equations involving the same variables.

The types of systems of linear equations are as follows:

The system of linear equations is -

- 5x + 6y = - 11

6y = x + 5

We can write -

6y = x + 5

x = 6y - 5

Now, we can write -

- 5(6y - 5) + 6y = - 11

- 30y + 25 + 6y = - 11

- 24y = - 11 - 25

- 24y = - 36

y = 36/24

y = 9/6

y = 3/2

y = 1.5

Then, we can write -

x = 6 x 3/2 - 5

x = 9 - 5

x = 4

Therefore, the solution set to the given system of equation is -

x = 4 & y = 1.5.

The number of hours it would take Miller's family to reach their destination is [tex]2\frac{2}{3}[/tex] hours. This can be solved using the concept of fractions.

A fraction is expressed as p/q, where q ≠ 0. Proper fractions, in which the numerator is less than the denominator, and improper fractions, in which the numerator is higher than the denominator, are the two sorts of fractions.

Given, The Miller family must drive 8 hours to reach their destination.

The first time they stopped after driving  hours and again for the second time they stopped after driving  hours.

Therefore the total hours they drive is,

= [tex](2\frac{2}{3}+2\frac{2}{3})[/tex] hours.

= (8/3 + 8/3) hours.

= 16/3 hours.

= [tex]5\frac{1}{3}[/tex] hours.

So, The number of hours they still need to drive is,

= (8 - 16/3) hours.

= (2⁴ - 16)/3 hours.

= 8/3 hours.

On opening night, the number of adult tickets and the number of children tickets were sold are respectively, 210 and 110

An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.

For example, 2x+3

Given that,

Total tickets sold = 320

Adult tickets = $25 each

Children tickets = $8 each

The total ticket sales= $6,130

Suppose, the number of adult tickets sold = x

So, the number of children tickets sold = 320 - x

Total sales = 6130

Total sales = adult tickets sold + children tickets sold

                  = 25×x + 8×(320 - x)

                  = 25x + 2560 - 8x

                  = 17x + 2560

6130-2560= 17x

               x = 210

Now, number of children ticket = 320 - 210

                                                    = 110

Hence, The numbers are respectively, 210 and 110

Answer: To complete the table, we need to find ratios that are equivalent to the ratio of time to number of wing beats for a honeybee.

We can start by finding the ratio of time to number of wing beats for the first data point:

9 seconds / 1917 wing beats = 9/1917

And the second data point:

23 seconds / 4899 wing beats = 23/4899

To find equivalent ratios, we can multiply or divide both parts of the ratio by the same number, without changing the value of the ratio. For example, we can divide both parts of the ratio by 9 to get:

9/1917 = (9/9) / (1917/9) = 1 / 213

We can also divide both parts of the ratio by 23 to get:

23/4899 = (23/23) / (4899/23) = 1/213

We can use this same method to find equivalent ratios for other values of time and number of wing beats.

Time (s)          Number of wing beats                   Ratio

9           1917                                                     9/1917 or 1/213

23                  4899                                                   23/4899 or 1/213

So, the ratio of time to a number of wing beats for a honeybee is equivalent to 1/213, regardless of the specific values of time and number of wing beats.

The probability of 50% shows that the  mean cholesterol level of the sample will be no more than 210 for the given mean and standard deviation.

As given in the question,

Area average represents the mean ' μ ' = 210 mg /dL

Standard deviation 'σ ' = 30 mg /dL

Sample 'n' =  48

Normal distribution 's' = σ /√n

                                     = 30 /√48

                                     = 4.35

Probability so that mean of the given sample not more than 210

By using central limit theorem we have,

Z = ( X - μ ) /s  

  = ( 210 - 210 )/ 4.35

  = 0

When Z = 0 it has p-value equals to 0.5.

0.5 = 50%

Therefore, the probability of 50% shows that the  mean cholesterol level of the sample will be no more than 210.

On average, an underground storage tank has a remaining useful life of between 10-20 years depending on the construction, maintenance, and environment it is in. The tank's remaining useful life is also dependent on the type of material used in its construction.

Tanks constructed from steel or fiberglass have a life span of around 15-20 years, while concrete tanks have a longer life expectancy of up to 25 years.  In this case, the tank has been in place for 15 years, which puts it at the midpoint of its expected life expectancy.

Depending on the maintenance and environment that the tank has been subjected to, it is not unlikely that it could last longer than its expected life, but it is recommended to inspect the tank periodically to ensure that it is still in good condition. If the tank is not properly maintained, the remaining useful life may be significantly shorter.

A 95% confidence interval for the mean of 3243 dollars.

In statistics, the confidence interval formula is used to express the degree of uncertainty surrounding a sample estimate of a population parameter. It is used to describe the degree of uncertainty surrounding a sampling technique.

Given random sample = 55

mean = $2900

standard deviation = $1300

Confidence Interval = m ± z(SD/√n)

n = Number of terms

m = Sample average

SD = Standard Deviation

z = Value corresponding to confidence interval in z table

value of z for 95% confidence interval is 1.96,

substitute the values in formula,

Confidence Interval = m ± z(SD/√n)

Confidence Interval = 2900 ± 1.96(1300/√55)

Confidence Interval = 2900 ± 343.581

Confidence Interval =  3243.581

Confidence Interval =  3243

Answer:

A dilation is a transformation that changes the size of a figure while keeping its shape the same. In a dilation with a scale factor of 1/2 and the origin as the center of dilation, each point in the figure is moved away from the origin by a factor of 1/2.

To find the new location of point B, we can apply this dilation to the coordinates of point B. Point B is located at (4,10), so we can multiply each coordinate by 1/2 to find the new location.

B'(x',y') = (1/2)(x,y) = (1/2)(4,10) = (2,5)

So the new location of point B, B' is located at (2,5) in the coordinate plane.

Yes, that's correct. In the slope-intercept form, the equation of a line is given as y = mx + b where m is the slope of the line.

The variable "m" represents the slope of the line, which is a measure of how steep the line is. It is calculated as the ratio of the change in the y-coordinate to the change in the x-coordinate, also known as the rise over the run.

A line with a positive slope will rise as it moves to the right, while a line with a negative slope will fall as it moves to the right. A line with a slope of zero is a horizontal line and one with an infinite slope is a vertical line.

The variable "b" is the y-intercept, which is the point where the line crosses the y-axis. It is the value of y when x = 0.
