Answer:
11.8
Step-by-step explanation:
5 + 10 + 12 + 4 + 6 + 11 + 13 + 51= 118
The average (mean) is equal to the sum of all the data values divided by the count of values in the data set.
Count = 10
Sum = 118

Answer:
minor arc
Step-by-step explanation:
This is a vocabulary question:
major arc: has a measure more than 180°minor arc: has a measure less than 180°semicircle: has a measure of exactly 180° (connects the ends of a diameter)__
Arc EA is a minor arc.
_____
Additional comment
In general, unless the two named points are the ends of a diameter, the arc is a minor arc. A major arc will generally be defined by designating a third point on the long arc connecting the same points on the circumference. For example, EDA, ECA, and EBA all designate the major arc connecting points E and A. (We can also use the descriptor, "major arc EA.") Without any of these extras designating the major arc, EA is considered to be the minor arc.

Use the shell method to write and evaluate the definite integral that represents the volume of the solid generated by revolving the plane region about the y-axis.
y = 3 − x
The volume of the solid generated by revolving the plane region y=3−x about the y-axis is 9π cubic units.
What is integration?It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.
We have a function:
y = 3 - x
From the graph:
Shell radius = y
Height = 3 - y
From the shell method, we can write the integral as follows:
[tex]\rm Volume =2\pi\int\limits^0_{-3} {y(3-y)} \, dy[/tex]
[tex]\rm Volume =2\pi\int\limits^0_{-3} {(3y-y^2)} \, dy[/tex]
After solving the above definite integral, we will get volume:
Volume = 9π cubic units
Thus, the volume of the solid generated by revolving the plane region y=3−x about the y-axis is 9π cubic units.

A circular flower garden surrounds a sculpture on a square base as shown. What is an expression for the area of the flower garden?
The number from the center of the square is 6x and the flower garden area is 4x
The given object is made up of circle and squares. The expression for the area of the flower garden is 4π²(9π - 4)square units
Area of composite objectThe given object is made up of circle and squares. To find the area of the garden, we wil use the expression
Area of the garden = area of circle - area of square
Find the area of circle
Area = πr²
Area = π(6π)²
Area pf circle = 36π³ square units
For the square
A = length * length
A = 4²π²
A = 16π²square units
Take the difference
D = 36π³ - 16π²
D =4π²(9π - 4)square units
Hence the expression for the area of the flower garden is 4π²(9π - 4)square units

The ceiling of Stacy's living room is a square that is 22 ft long on each side. Stacy knows the diagonal of the ceiling from corner to corner must be longer than 22 ft, but she doesn't know how long it is.
Solve for the length of the diagonal of Stacy's ceiling in two ways:
(a) Using the Pythagorean Theorem.
(b) Using trigonometry.
Round each answer to the nearest whole number and make sure to show all your work. (Hint: the answers should be the same!)
Answer:
I don't understand trig very well but I do get pythagorean theorem, which I can help with. Your final answer will end up being 31.
Step-by-step explanation:
First off the formula for pythagorean theorem is a^2 + b^2 = c^2
We know that C stands for the hypotenuse so we want to know what C is.
A and B are both 22 so our equation turns into 22^2 + 22^2 = c^2
22 squared is 484 which leads to 484 + 484 = c^2
484 + 484 = 968
968 is our C^2 but we still need to find the square root
The square root of 968 is 31.11269837... and a whole lot of other numbers
You round that out to 31 and get the length of your diagonal

The given equation is y=(x-2)(x+3)
The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x.
Here, (x-2)(x+3)=0
(x-2)=0 and (x+3)=0
x=2 and x=-3

Question 13
You deposit $8,400 in an account earning 3.6% interest compounded monthly.
a. How much will you have in the account in 20 years?
b. How much interest will you earn?
Answer:
A = $17,238.65
I (interest) = $8,838.65
Step-by-step explanation:
Using the formula A = P(1 + r/n)^nt
A = $17,238.65
A = P + I where
P (principal) = $8,400.00
I (interest) = $8,838.65
First, convert R as a percent to r as a decimal
r = R/100
r = 3.6/100
r = 0.036 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 8,400.00(1 + 0.036/12)^(12)(20)
A = 8,400.00(1 + 0.003)^(240)
A = $17,238.65
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $8,400.00 at a rate of 3.6% per year compounded 12 times per year over 20 years is $17,238.65
28 out of 35 students in ms. baileys class have older siblings. what percent of the class has older siblings
Answer:
80%
Step-by-step explanation:
We can get the percent value of the amount of students who have older siblings by diving 28 by 35.
28 / 35 = 0.8
We can convert this decimal into a percentage, giving us 80%.
Therefore, we know that 80% of the students in Ms. Bailey's class have siblings.
The cost of gas increases monthly at a rate of 3.2%. If gas cost $1.75 today. How much will it cost in 3 years? ( round to the nearest cent (2 decimal places) )
Answer:
$1.92
Step-by-step explanation:
present cost = $1.75
time = 3 years
rate = 3.2%
cost after three years = present cost (1 +[tex]\frac{R}{100}[/tex] )^3
=$1.75 ([tex]\frac{103.2}{100}[/tex])^3
=$1.75*1.099
=$1.92
Threrefore , after 3 years cost of gas will be $1.92.
