Answer:
mean = 10
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
= [tex]\frac{6+7+10+12+12+13}{6}[/tex]
= [tex]\frac{60}{6}[/tex]

We use the formula V = πr2h to find the volume of a cylinder. Make h the subject of the formula.
Answers
Answer:
V / ( pi r^2) = h
Step-by-step explanation:
V = pi r^2 h
Divide each side by pi r^2
V / ( pi r^2) = pi r^2 h / pi r^2
V / ( pi r^2) = h
A certain shampoo is available in two sizes. A 14.2 ounce bottle costs $3.98. A 33.9 ounce bottle costs $9.98. Find the unit price for each size. Then state which size is the better buy based on the unit price. Round your answers to the nearest cent. Thank you!
Answers
You take the total price of the shampoo bottle and divide it by how many ounces there are to get the price per ounce.
P.s. it says I’m a beginner because I made a new account
Answer:
A 14.2 ounce bottle costs $3.98 is the better buy
Step-by-step explanation:
Find the price per ounce for each
A 14.2 ounce bottle costs $3.98
3.98 /14.2 =.28028169 = .28 per ounce
A 33.9 ounce bottle costs $9.98
9.98/33.9 =.29439528 = .29 per ounce
Which of the following choices is a linear function?
O f(x) = x2 – 3x+ 2
O f(x) = 3x3 – 3x + 2
O f(x) = -3x + 2
Answers
Answer:
f (x) = x2 - 3x + 2
Step-by-step explanation:
Answer:
f(x)=-3x+2
Step-by-step explanation:
The first one is a quadtratic function because it is in quadtratic form.
The second one is also not linear because it looks like a squiggly line. Sorry I forgot what they are called but I know it is not linear.
That leaves the last one is is linear and should be going down because there is a negative in front of the coefficient. It also has so exponent to prove why it is linear even further.

An ice-making machine needs to be switched on
for 10 minutes before the production of ice begins.
The mass, in tờnnes, of ice produced is directly
proportional to the number of hours of production.
Given that 20 tonnes ofâce are produced when the
machine runs for half an hour, find the mass of ice
manufactured when the machine runs for
1.75 hours
Answers
Since the question explicitly stated that ice production is proportional to time, we're going to have to use proportion fractions. Remember to convert hours into minutes as well.
Consider the expression
-4b + 8c + 12 - 8b - 2c + 6.
Part A
Factor the simplified expression using the GCF.
Answers
Answer:
-12 b + 6 c + 18
Step-by-step explanation:
-4 b + 8 c + 12 - 8 b - 2 c + 6
After simplification, the correct value is,
⇒ 6 (- 2b + c + 3)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We haver to given that;
The expression is,
⇒ -4b + 8c + 12 - 8b - 2c + 6.
Now, We can simplify by combine like terms as;
⇒ -4b + 8c + 12 - 8b - 2c + 6.
⇒ - 12b + 6c + 18
And, GCD of 12, 6, 18 = 6
Hence, Take 6 as common as;
⇒ - 12b + 6c + 18
⇒ - 2×6b + 6c + 3×6
⇒ 6 (- 2b + c + 3)
Therefore, The solution of the expression is,
⇒ 6 (- 2b + c + 3)

a colleague needs to move a 500 pound object that's on a lever. the fulcrum is 6 inches from the object. If your colleague weighs 180 pounds how far will your colleague need to be from the fulcrum to move the object? Use the formula B = (P x A) ÷ W, and round your answer to two decimal places.
Answers
Answer:
Step-by-step explanation:
The easier way to figure this is by using the concept of torque in physics. If the torque of the man is greater than that experienced by the box, the lever will tilt in the man's favor (in other words, he will move down and the box will be lifted). Torque is found by multiplying the perpendicular force by the length of the lever arm. Because we want the man's torque to be greater than the box's torque, the inequality is:
[tex]\tau_{man}>\tau_{box}[/tex] and
[tex]180r>500(.1524)[/tex] That decimal is 6 inches in terms of meters.
180r > 76.2 so
r > .42 meters or `16.67 inches. The man has to sit at a distance greater than 16.67 inches in order for the box to be lifted by the lever.

Is the expression x^3·x^3·x^3 equivalent to x^3·3·3? Why or why not? Explain your reasoning. Please show and explain all steps thoroughly. Thank you for your time and help. There is a screenshot of the problem in case my typed version of the problem is not as understandable.
Answers
The two expressions are not equivalent because one of the the rule of exponents is that when the bases of the exponents are the same (in this case, they're all x) then you can add the powers. Thus, the alternative expression should be x^(3+3+3).
