What percent of the circle is shaded?
Can you also explain how to get the answer?

Answer:

P + S / P [(r - 1) P - S] dP

Step-by-step explanation:

If r = 0.10 and S = 900 then,

P + 900 /  P [(0.10 - 1) P - 900] dP

Solving the equation we get,

P + 900 = (B - 0.9A)P - 900A

If A = -1,

B = 0.10

t = 0 and P = 10,000

ln 10000 - 1 /9 ln (0.9 * 10000 + 900) + C

C = 10.2326.

Answer:

The probability of of a randomly chosen student being exactly 21 years old.

= 1.293

Step-by-step explanation:

Step(i):-

Given Population  size n = 500

Mean of the Population = 20 years and 6 months

                                       = [tex]20 + \frac{6}{12} = 20 +0.5 = 20.5 years[/tex]

Standard deviation of the Population = 2 years

Let 'X' be the range of ages of the students on campus follows a normal distribution

Let   x =21

            [tex]Z = \frac{x-mean}{S.D}[/tex]

            [tex]Z = \frac{x-mean}{S.D} = \frac{21-20.6}{2} =0.2[/tex]

The probability of a randomly chosen student being exactly 21 years old.

P( Z≤21) =  0.5 + A( 0.2)

            = 0.5 +0.793

           =  1.293

Answer:

B. The product of two irrational numbers can be rational or irrational.

Step-by-step explanation:

An irrational number is a number that is real and it cannot be written or expressed as a fraction.

For example , 2√3, √5 are irrational numbers.

A rational number is a number that is real and can be expressed as a fraction. It is a whole number. For example: 5, 7 are rational numbers

In the above question, we are a pair of rational and irrational number, 2 irrational numbers and we are asked to draw conclusions from their product

a) √2•√2 = √2 × √2 = √4 = 2 = rational number

b) √5•√7 = √5 × √7 = √35 = Irrational number

c) √2•18 = √2 × 18 = 18√2 = Irrational number

d) √2•√6 = √2 × √6 = √12 = Irrational number.

My conclusion from the above results is option B, which states that

B. The product of two irrational numbers can be rational or irrational.

Answer:

2 2/3

Step-by-step explanation:

1) First, find the absolute value of -2 2/3. The absolute value is 2 2/3.

2) Next, convert 2 2/3 to an improper fraction because we want to find the simplest form. The improper fraction is 8/3.

3) Finally, 8/3 cannot be reduced any further, so the answer is 2 2/3.

The absolute value is denoted by |x|.

Any negative value put in absolute becomes positive.

The absolute value of [tex]-2\frac{2}{3}[/tex] as a mixed number in its simplest form is [tex]2\frac{2}{3}[/tex].

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

[tex]-2\frac{2}{3}[/tex]

We have to write its absolute value.

The absolute value is denoted by |x|.

Any negative value put in absolute becomes positive.

Example:

|-1| = 1

|1| = 1

|-2| = 2

Now,

| [tex]-2\frac{2}{3}[/tex] | = [tex]2\frac{2}{3}[/tex]

This is in its simplest form.

Thus,

The absolute value of [tex]-2\frac{2}{3}[/tex] as a mixed number in its simplest form is [tex]2\frac{2}{3}[/tex].

Step-by-step explanation:

The average rate of change of [tex]g ( x ) = 5 x^3 + 4[/tex] from x = − 1 to x = 3 is 35.

"It is a measure of how much the function changed per unit, on average, over that interval."

The average rate of change of function f over the interval a ≤ x ≤ b, is given by this expression: [tex]\frac{f(b)-f(a)}{b-a}[/tex]

For given question,

We have been given a function [tex]g ( x ) = 5 x^3 + 4[/tex]

We need to find the average rate of change of function g(x) from x = − 1 to x = 3

Here, a = -1 and b = 3

[tex]g(a)\\= g(-1)\\=5(-1)^3+4\\=-5+4\\=-1[/tex]

and the value of g(b) is,

[tex]g(b)\\=g(3)\\=5(3)^3+4\\=135+4\\=139[/tex]

Using the formula of average rate of change of function,

[tex]\frac{f(b)-f(a)}{b-a}\\\\=\frac{139-(-1)}{3-(-1)}\\\\=\frac{140}{4}\\\\=35[/tex]

Therefore, the average rate of change of [tex]g ( x ) = 5 x^3 + 4[/tex] from x = − 1 to x = 3 is 35.

Answer:

160 kilometers per hour

9560 kilometers per minute

Answer:

Speed of the car is equivalent to 159.39 KM/hour or 2.6565 Km/min.

-Step by Step-:

-The speed of the car is given as  99 mi/hour.

Now, WE know that 1 Mile = 1.61 KM

Hence, in order to calculate the speed of the car in KM/hour we will multiply the speed of the car in miles with 1.61.

⇒The speed of the car in KM/hour = 99 × 1.61 KM = 159.39 KM/hour

Also, 1 hour = 60 minutes

⇒ Speed of the car in KM/min = (159.39) ÷ 60 = 2.6565 K/min

Answer:

25 Minutes

Step-by-step explanation:

Well, 1/4 of an hour is obviously 15 minutes. So if she read 3/5 of the book in 15 minutes, you have to find how long it took her to read 1/5 of the book. If 15 minutes is 3/5, then 15/3 is 5, which is the time it took to read 1/5 of the book. You add 10 to 15 and you get 25. I hope this helps!

If Jada can read 3/5 of a book in 1/4 of an hour, it will take her 5/12 of an hour to read one whole book

Time taken to read 3/5 of the book = 1/4 hours

To get the time taken to read 1 book, we will divide 1/4 hours by 3/5

Time taken to read 1 book = [tex]\frac{1}{4}\div \frac{3}{5}[/tex]

The division sign changes to multiplication  and 3/5 is changed to its reciprocal (5/3)

Time taken to read 1 book = [tex]\frac{1}{4}\times\frac{5}{3}[/tex]

Time taken to read 1 book = [tex]\frac{5}{12}[/tex]

If Jada can read 3/5 of a book in 1/4 of an hour, it will take her 5/12 of an hour to read one whole book

Answer:

288 cu in

Step-by-step explanation:

The Two end pieces

l = 6

w = 4

h = 4

V = l*w*h

V = 6*4*4

V = 96

But there are two end pieces. So the volume for both is 2 * 96 = 192

Middle Piece

L = 8

w = 4

h = 3

Volume = l * w * h

Volume = 8 * 4 * 3

Volume = 96

Total Volume

Total Volume = 96 + 192

Total Volume = 288 Cu in
