How to calculate the mean?It should be noted that mean simply means average. The mean of the men will be:
= (27 + 20 + 20 + 19 + 19 + 25 + 24 + 21 + 22 + 24) / 10
= 221/10
= 22.1
Therefore, the mean of the ages of the men that are given will be 22.1.

Answer=b+6>-27
b>-33
Step-by-step explanation
And by transposition, you can move the plus 6 to the right of the inequality sign, and change the plus to the minus, so you just compute the minus 27 plus 6. b >-33
Match each set of equations with the move that turned the first equation into the second.

(Will l give 25 points!) Solve the system of linear equations by substitution. -8x + y = 5 and 5x - y = 3
Answers
Answer:
x = -8/3 and y = -49/3
Step-by-step explanation:
(Step 1) To solve using substitution, you first need to isolate a variable in one of these equations. I chose to isolate "y" in the following equation.
-8x + y = 5 <--- Original equation
y = 5 + 8x <--- Add 8x to both sides
(Step 2) Now, substitute (5 + 8x) for "y" in the second equation.
5x - y = 3 <--- Original equation
5x - (5 + 8x) = 3 <--- Substitute 5 + 8x for "y"
5x - 5 - 8x = 3 <--- Distribute (-) in the parentheses
-3x - 5 = 3 <--- Combine terms with "x"
-3x = 8 <--- Add 5 to both sides
x = -8/3 <--- Divide both sides by -3
(Step 3) Since you know the value of "x", plug it into one of the equations to solve for "y".
y = 5 + 8x <--- Original (rearranged) equation
y = 5 + 8(-8/3) <--- Plug (-8/3) for "x"
y = 5 - 64/3 <--- Multiply
y = 15/3 - 64/3 <--- Convert 5 into a fraction
y = -49/3 <--- Subtract
(Step 3.5) You can check your work by plugging "y" into the other equation to see if the answer for "x" is the same.
5x - y = 3 <--- Original equation
5(-8/3) - y = 3 <--- Plug (-8/3) for "x"
-40/3 - y = 3 <--- Multiply
-40/3 - y = 9/3 <--- Convert 3 into a fraction
-49/3 - y = 0 <--- Subtract both sides by 9/3
-49/3 = y <--- Add both sides by "y"
The value of the system of equations is x = -8/3 and y = -49/3.

Step-by-step explanation:
I'm not sure, but if you divide the number of people by each candidate, you'll get a value that the number of candidates will equal the number of people. I repeat I'm not sure of my answer.
622,620 ÷ 3 = 207,540
622,620 ÷ 9 = 69,180

Answers
Answer:
a. true
b. false
c. false
d. false

Step-by-step explanation:
a is true because the graph is measuring the weight of the box based on the number of cookies in it, and the box has weight even without cookies in it.
b is false because the slope of the line is 1/2, and each cookie weighs 1/4 oz.
c is false because there is an association between the number of cookies and the weight of the box.
d is false because that is the weight of one cookie, and doesn't take into account the weight of the box by itself.
e is true because the graph shows that at 13 cookies, the box weighs around 3.75 ounces.
