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

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

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.

The relative frequency of getting a tail on the next toss will be 0.40.

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

⇒ 20/50

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]

Blue whales, about 80 feet in length and over 250,000 pounds in weight, are much bigger than whale sharks.

The blue whale is 1  × 10^1 times heavier than a white rhinoceros.

The number is written in the form  [tex]a \times 10^b[/tex] where we have it [tex]1 \leq a < 10[/tex]. The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. Scientific notations have some of the profits as Better readability due to compact representation. Its value in terms of the power of 10 is known, which helps in the easy comparison of quantities differing by a large value.

The weight of the animals can be written in scientific notation.

To determine that how much heavier the blue whale is, we need to divide the weight of the blue whale by the weight of the white rhinoceros.

The division operation that is used to group a number into equal parts using another number.

Weight of the blue whale ÷ weight of the white rhinoceros

2 x [tex]10^5[/tex] ÷ 2 x [tex]10^4[/tex]

(2 ÷ 2) x ([tex]10^{5-4}[/tex])

1  × 10

Answer:Anthony

Step-by-step explanation:

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

the answer is -72

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]
