Find the area bounded by the given curves:
y=2x−x2,y=2x−4
Answer:
[tex]A = [\frac{32}{3}][/tex]
Step-by-step explanation:
Given
[tex]y_1 = 2x - x^2[/tex]
[tex]y_2 = 2x - 4[/tex]
Required
Determine the area bounded by the curves
First, we need to determine their points of intersection
[tex]2x - x^2 = 2x - 4[/tex]
Subtract 2x from both sides
[tex]-x^2 = -4[/tex]
Multiply through by -1
[tex]x^2 = 4[/tex]
Take square root of both sides
[tex]x = 2[/tex] or [tex]x = -2[/tex]
This Area is then calculated as thus
[tex]A = \int\limits^a_b {[y_1 - y_2]} \, dx[/tex]
Where a = 2 and b = -2
Substitute values for [tex]y_1[/tex] and [tex]y_2[/tex]
[tex]A = \int\limits^a_b {(2x - x^2) - (2x - 4)} \, dx[/tex]
Open Brackets
[tex]A = \int\limits^a_b {2x - x^2 - 2x + 4} \, dx[/tex]
Collect Like Terms
[tex]A = \int\limits^a_b {2x - 2x- x^2 + 4} \, dx[/tex]
[tex]A = \int\limits^a_b {- x^2 + 4} \, dx[/tex]
Integrate
[tex]A = [-\frac{x^{3}}{3} +4x](2,-2)[/tex]
[tex]A = [-\frac{2^{3}}{3} +4(2)] - [-\frac{-2^{3}}{3} +4(-2)][/tex]
[tex]A = [-\frac{8}{3} +8] - [-\frac{-8}{3} -8][/tex]
[tex]A = [\frac{-8+ 24}{3}] - [\frac{8}{3} -8][/tex]
[tex]A = [\frac{-8+ 24}{3}] - [\frac{8-24}{3}][/tex]
[tex]A = [\frac{16}{3}] - [\frac{-16}{3}][/tex]
[tex]A = [\frac{16}{3}] + [\frac{16}{3}][/tex]
[tex]A = [\frac{16 + 16}{3}][/tex]
[tex]A = [\frac{32}{3}][/tex]
Hence, the Area is:
[tex]A = [\frac{32}{3}][/tex]

-(3x - 12) = 9x - 4 *Hint: Distributive the negative
Answer: x=1+1/3
Step-by-step explanation: -(3x-12)=9x-4
We move all terms to the left:
-(3x-12)-(9x-4)=0
We get rid of parentheses
-3x-9x+12+4=0
We add all the numbers together, and all the variables
-12x+16=0
We move all terms containing x to the left, all other terms to the right
-12x=-16
x=-16/-12
x=1+1/3
A grain silo has a circular base with an area of 260 square feet and is 21 feet tall What is the total volume?
The correct answer is 5460 cubic feet or 5460 [tex]ft^{3}[/tex]
Explanation:
The silo has a cylindrical shape, in this context, the volume of the silo or any other cylinder can be calculated by using the formula [tex]Volume =\pi r^{2} h[/tex]. In this formula the symbol [tex]\pi[/tex] refers to the number 3.1415..., the letter [tex]r[/tex] refers to the radius of the base and the letter [tex]h[/tex] refers to the height.
Moreover, in this case, it is known the heigh (21 feet) and the area of the base (260 square feet). Additionally, this area of the base is the result of the formula [tex]Area = \pi r^{2}[/tex], which is exactly the first section of the formula to find the volume. This implies that by multiplying the area of the base by the height the volume is known. Here is the process:
[tex]Volume = \pi r^{2} h[/tex] or [tex]Volume = Ah[/tex] (Area of the base × height)
[tex]V = 260 square feet[/tex] × [tex]21 feet[/tex]
[tex]V = 5460 cubic feet[/tex]

A teacher spent $259.20 on classroom
supplies. This was 80% of the total classroom
budget. How much was the total budget?
Answer:
$324
Step-by-step explanation:
We need to make a proportion:
[tex] \frac{259.20}{x} = \frac{80}{100} [/tex]
[tex]25920 = 80x[/tex]
[tex]x = 324[/tex]
x is 1%. So 100% = 324*100 = 32400 cents = $324

What is the relative frequency of getting a tails on the next toss?
The expirmental probability us 28/50
Theoretically the probability is 25/50 because that would be half :)
The relative frequency of getting a tail on the next toss will be 0.40.
How to find the relative frequency?Relative frequency is the ratio of the considered subgroup's count to the whole count.
A coin is tossed 50 times, and it lands on tails 20 times.
Then the relative frequency of getting a tail on the next toss will be
The probability of getting tail is 1/2.
Then the relative frequency will be

Suppose a population doubles every 20 years. Then each year it increases by ___ percent.
Answer:
It’s 3.5 percent
Step-by-step explanation:
Population increases by 3.6% every year.
The population in question doubles every 20 years and you need to find out the annual rate of increase.
You can use the rule of 72 which allows you to calculate the doubling time of a variable by the formula:
Time to double = 72 / Rate
As we already have the time the double, the rate is:
20 = 72 / Rate
Rate x 20 = 72
Rate = 72/20
Rate = 3.6%
The population therefore increases by 3.6% every year.

work for a publishing company. The company wants to send two employees to a statistics conference. To be fair, the company decides that the two individuals who get to attend will have their names randomly drawn from a hat. (a) Determine the sample space of the experiment. That is, list all possible simple random samples of size . (b) What is the probability that attend the conference? (c) What is the probability that attends the conference? (d) What is the probability that stays home?
Answer:
Step-by-step explanation:
Here is the complete question.
Dominique, Marco, Roberto , and John work for a publishing company. The company wants to send two employees to a statistics conference. To be fair, the company decides that the two individuals who get to attend will have their names drawn from a hat. This is like obtaining a simple random sample of size 2. (a) Determine the sample space of the experiment. That is, list all possible simple random samples of size n = 2. (b) What is the probability that Dominique and Marco attend the conference? (c) What is the probability that John attends the conference? (d) What is the probability that John stays home?
Since there are four employees to select the two to send from. then for us to get the sample space for the experiment we need to merge all possible two employees and represent them as set.
Let D = Dominique, M = Marco, R = Roberto and J = John
a) The sample space for the experiment is the total number of possible outcomes that we can have. It is as given below
S = 4C2 = 4!/(4-2)!2! (Selecting 2 out of 4 employees)
Total sample space = 4!/2!2!
Total sample space = 4*3*2!/2!2
Total sample space = 12/2 = 6
The sample space are S = {DM, DR, DJ, MR, MJ, RJ}
b) Probability is the ratio of number of event to the sample space.
P = n(E)/n(S)
Given n(S) = 6
n(E) is the event of Dominique and Marco attending the conference.
E = {DM}
n(E) = 1
P(D and M) = 1/6
Hence the probability that Dominique and Marco attend the conference is 1/6
c) For John to attend the conference, the event outcome will be given as;
E = {DJ, MJ, RJ}
n(E) = 3
n(S) = 6
Probability for John to attend the conference is 3/6 = 1/2
d) Probability that John stays at home = 1 - Prob (John attends the conference)
Probability that John stays at home = 1 - 1/2
Probability that John stays at home = 1/2
