32. XY, given X(7, 2) and Y(2, 0)
Domain
Range

Answers

Answer 1

Based on the coordinates of XY which are X(7, 2) and Y(2, 0), the domain and range are:

Domain : (2, 7)Range: (0, 2)

What are domain and range?

The domain of a line refers to all the points on that line that the value of the x-axis can take.

In line XY, the only two x-axis values are 7 and 2. This means that the domain is therefore (2, 7).

The range of a line on the other hand, are all the points that the value on the y-axis can take.

The range in this case is therefore (0, 2).

la razon de hombres a mujeres que trabajan en una campañia es de 4 a 7. Si hay 143 empleados en total ¿Cuantas mujeres trabajan en la compañia?​

Answers

In a company of 143 employees, the number of women working in the company is 91.

The quantitative relation is outlined because the comparison of 2 quantities of a similar units that indicates what proportion} of 1 amount is gift within the alternative quantity.Ratios may be classified into 2 varieties. One half|is a component|is an element} to part quantitative relation and also the alternative is an element to whole quantitative relation.

Given,

Men : Women = 4 : 7

Total number of employees =  143

Let us take a multiplying factor of x

This implies, Number of men = 4x , Number of women = 7x

Using the given data, we get 4x + 7x = 143

                                                  11x = 143

                                                   x = 143 / 11

                                                   x = 13

Number of men = 4x = 4 (13) = 52

Number of women = 7 (13) = 91

Therefore, using the concept of RATIO, we get the number of women working in the company as 91.

find the slope of the line in the picture

Answers

The slope of the line in the picture is 2.8

How to find the slope of the line in the picture?

To calculate the slope of the line, we make use of two points on the line

The two points to use are

(0, 0) and (25, 70)

The slope of the line is then calculated as

Slope = (y2 - y1)/(x2 - x1)

So, we have

Slope = (70 -0)/(25 - 0)

Evaluate

Slope = 2.8

Note that the slope can also be regarded as the constant average rates of change or the gradient

Hence, the slope of the line in the picture is 2.8

Sarah

5x - 15 - 3x = 10 - (-3x + 20)

2x - 15 = 10 + 3x - 20

2x - 3x - 15 = -10 + 3x - 3x

How to illustrate the information?

It should be noted that an equation is simply used to illustrate the relationship between two variables.

In this case, the solution to the equation will be:

5x - 15 - 3x = 10 - (-3x + 20)

2x - 15 = 10 + 3x - 20

2x - 3x - 15 = -10 + 3x - 3x

-1x - 15 + 15 = -10 + 15

-1x = 5

x = -5

A sled team consists of 11 dogs and the musher. Each dog weighs 70 pounds and the musher weighs 160 pounds. What is the average weight of the sled team members?

a

b
115 pounds
c
73.5 pounds
d
77.5 pounds

Answers

The average weight of the sled team members is 77.5

What is an average value?

Average value can be calculated by finding the  sum of a set of numbers  then count the total number, then divide the sum with the  number of the counted values.

To calculate the average weight of the sled team members, then we know that there are  11 dogs and the musher, which implies that there are total number of 12 animals.

Then we can find the total number of the dogs as (11*70) =770 dogs, then we can add to the musher which makes the total number of (770+160)=930

Then the average weight of the sled team members is [tex]\frac{930}{12} =77.5[/tex]

Answers

The linear function for the percent change in the battery while Bailey is playing the gane is:

B(t) = 100 - 0.5t, 0 ≤ t ≤ 200.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For this problem, we have that:

The intercept is the initial battery, of 100.The slope is of -0.5, as the battery decays by 0.5% each minute.

Hence the function is:

B(t) = 100 - 0.5t.

The battery will be of 0, when:

B(t) = 0.

100 - 0.5t = 0.

t = 100/0.5.

t = 200.

Hence the function is:

B(t) = 100 - 0.5t, 0 ≤ t ≤ 200.

what percent of 54 is 23? explained

Answers

Answer: 42.59

Step-by-step explanation:

Step 1: First, write the problem as an equation: P% = X/Y

Step 2: Here, X is 23, Y is 54, so the equation is P% = 23/54

Step 3: A percent is a ratio of a number expressed out of 100. So P% means P/100

Step 4: Substitute P/100 instead of P% in the above equation, then P% = 23/54 becomes P/100 = 23/54

Step 5: Solve for P

P/100 = 23/54

P = (23/54) * 100 = 42.59

Therefore, 23 is 42.59 percent of 54

What is the slope of the line that passes through the points (-7, -2) and

Answers

Answer:

-4

Step-by-step explanation:

Compute the slope of the line through the following points:

p_1 = (-7, -2) and p_2 = (-2, -22)

The slope of the line through (x_1, y_1) and (x_2, y_2) is:

(y_2 - y_1)/(x_2 - x_1)

Substitute (x_1, y_1) = (-7, -2) and (x_2, y_2) = (-2, -22):

= (-22 - -2)/(-2 - -7)

-(-7) = 7:

= (-22 - -2)/(-2 + 7)

-2 + 7 = 5:

= (-22 - -2)/5

-(-2) = 2:

= (-22 + 2)/5

-22 + 2 = -20:

Answers

If Eva went to a shop and bought 3 apples, 5 peaches, 8 bananas, 1 pineapple, and 3 melons, then the mean and median of her purchase are equal to 4 and 3 respectively.

Mean can be described as the most common value in a group of numbers. The mean of a certain set can be found by the ratio of the sum of the values to the number of values.

Mean = Sum total of the expressions/ Number of expressions

Sum of the values = 3 + 5 + 8 + 1 + 3 = 20

Number of values = 5

Mean = 20 / 5

Mean = 4

Median can be described as the central number in a series of numbers or a dataset.

If we arrange the given dataset in ascending order, that is from smallest to largest, then the median can be found as follows,

1 + 3 + 3 + 5 + 8

As the middle number is 3, therefore the median of the given data set is equal to 3.

Therefore, the mean and median of her purchase are calculated to be 4 and 3 respectively.
