Answer: 30.2
Explanation:
The mean is calculated by taking the sum of the values and dividing by the count.
For instance, for the 6 women, with the mean being 31, we can see that the ages summed to 186:
186
6
=
31
And we can do the same for the men:
116
4
=
29
And now we can combine the sum and count of the men and women to find the mean for the office:
186
+
116
10
=
302
10
=
30.2
Step-by-step explanation:
9514 1404 393
Answer:
30
Step-by-step explanation:
The total of the ages of the 11 women is 11·31 = 341. The total of the ages of the 6 men is 6·29 = 174. Then the total of the ages of all 17 people in the office is ...
341 + 174 = 515
and their average age is ...
515/17 ≈ 30.294 ≈ 30
The mean age of the people in the office, to the nearest year, is 30.
_____
The mean is the total divided by the number of contributors. Then the total is the mean times the number of contributors.

The scale of a map is 0.5 inches :10 km. Find the actual distance corresponding to the map distance of 10 inches.
Answer:
200 km
Step-by-step explanation:
Create a proportion where x is the actual distance:
[tex]\frac{0.5}{10}[/tex] = [tex]\frac{10}{x}[/tex]
Cross multiply and solve for x:
0.5x = 100
x = 200
So, the actual distance is 200 km

Write a formula for the given measure. Let P represent the perimeter in inches, and w represent the width in inches. Identify which variable depends on which in the formula.
Complete Question:
Write a formula for the given measure. Let P represent the perimeter in inches, and w
represent the width in inches. Identify which variable depends on which in the formula.
*The perimeter of a rectangle with a length of 5 inches
Answer:
P = 2(5 + w)
Or
P = 20 + 2w
P is the dependent variable
w is the independent variable
P depends on w.
Step-by-step explanation:
Given:
Perimeter of rectangle = P
Width of the rectangle = w
Length of the rectangle = l = 5 in.
Formula for perimeter of a rectangle = 2(length + width)
Plug in the values. Formula for the given measure would be:
P = 2(5 + w)
Or
P = 20 + 2w
P is the independent variable, while w is the dependent variable.
This is because the Perimeter (P) of the rectangle is dependent on the width (w). Whatever value of w we get would determine the value of P were would get. Therefore,
P depends on w.

Match the graph with its equation.
A. –6x – 2y = 12
B. –6x + 2y = 12
C. 6x + 6y = 12
D. 6x + 2y = 12
Answer:
The answer is A. -6x-2y=12.
Step-by-step explanation:
In order to graph the equation, start by rewriting the equation in slope-intercept form. To rewrite the equation in slope-intercept form, add 6x to both sides of the equation, and then divide each term by -2 and simplify. Now, the equation should look like y= -6-3x.
Using the slope-intercept form, you can find the slope and y-intercept. By using the formula of y= mx+b, m= -3 and b= -6. Thus, the slope is -3 and the y-intercept is (0,-6).
Now, you can create a table of x and y values to graph the equation. After graphing the table of x and y values, the final answer is -6x-2y=12.

Drew has two cats. One cat weighs 17 pounds, and the other one weighs 1212 pounds. Audrey’s dog weighs 33 pounds.
What is the difference in ounces between Audrey’s dog and the combined weights of Drew’s cats?
Enter your answer in the box.
Answer:
48 ounces
Step-by-step explanation:
Answer:
64 ounces.
Step-by-step explanation:
combined weigh = weight of cat 1 + weight of cat 2
combined weigh = 17 + 12 = 29 pounds
The difference in weight of the Dog's weigh by the combined cat's weigh is the subtraction between the two, so we have:
Difference in weigh = 33 - 29 = 4 pounds
We now have to convert it to ounces, since 1 pound contains 16 ounces we can multiply the value of the weigh in pounds by 16 to obtain the final value:
Difference in weigh = (4 pounds)* 16 = 64 ounces

line cd in DE are tangent to circle a shown below ifCE is 130° what is the measure of angle CDE
20°
40°
42.5°
50°
Answer:
m<CDE = 50°
Step-by-step explanation:
Recall: when an angle is formed outside a circle by two tangents, the angle formed = ½(the difference between the measures of the intercepted arcs), based on the outside angles theorem.
This implies that:
m<CDE = ½(Arc CBE - Arc CE)
Arc CE = 130°
Arc CBE = 360° - 130° = 230°
Plug in the values
m<CDE = ½(230 - 130)
m<CDE = ½(100)
m<CDE = 50°
The measure of angle m<CDE is 50 degrees
Circle geometryFrom the diagram shown, the angle at the vertex is equal to half the difference of the angles at the intercepted arc.
Given
Angles at the arcs are 130 and 230 (360 - 130)Angle at the vertex = m<CDEm<CDE = 1/2(230-130)
m<CDE = 1/2(100)
m<CD = 50 degrees
Hence the measure of angle m<CDE is 50 degrees

A public health expert is worried that a recent outbreak of a disease may be related to a batch of spinach from a certain farm. She wants to test the plants at the farm, but it will ruin the crop if she tests all of them.If the farm has 5,000 spinach plants, describe a method that would produce a random sample of 10 plants.Why would a random sample be useful in this situation?
Answer: Systematic Random Sample
Step-by-step explanation:
Based on the information given, the method that would produce a random sample of 10 plants is the systematic random sample.
Systematic sampling is referred to as a probability sampling method whereby a random sample, that has a fixed periodic interval, will be chosen from the larger population. It should be noted that the fixed periodic interval, can be gotten by dividing the population by desired sample size.
In this case, since there are 5000 plants and there needs to ba a random sample of 10 plants, the fixed periodic interval will be: = 5000/10 = 500th plant. That means the 500th plant will be chosen.

Identify the triangle, ABC, which has a 72° angle and a 36° angle.
The triangle ABC would be an isosceles triangle.
What is an isosceles triangle?An isosceles triangle has two equal sides as well as two equal angles. The Greek words iso (same) and Skelos are the sources of the name (leg). An equilateral triangle is one in which all of its sides are equal, whereas a scalene triangle is one in which none of its sides are equal.
Given, Two angles of triangle ABC are 72 and 36 (in degrees). Since the sum of all the angles in a triangle is 180 degrees. Hence,
72 + 36 + third angle = 180
third angle = 72
Since if a triangle has two equal angles in it. Then it is known as an isosceles triangle.
Therefore, The given ABC triangle would be an isosceles triangle.

Lisa and conner had $360 altogether. After Connor gave Lisa 40% of his money, she had the same amount of money as he did. How much money did Conner have in the beginning?
Answer:
Conner had 225 in the beginning
Step-by-step explanation:
Let lisa's money be L
and Conots money be C
C+L= 360----------------1
Connor gave Lisa 40% of his money,
L= 0.4C+L
C= 0.6C
L=0.4C+L=C
C=0.4C+L---------------2 she had the same amount of money as he did
C-0.4C=L
`0.6C=L
Put L=0.6C in eqn 1
C+0.6C= 360
1.6C= 360
C= 360/1.6
C=225
C+L= 360----------------1
225+L=360
L= 360-225
L= 135
