The area of the semicircle with the given diameter is 189.97 mm^2

The given parameters are

Diameter, d = 22 mm

The area of the semicircle is calculated as

A = 1/2 * pi * (d/2)^2

So, we have

A = 1/2 * 3.14 * (22/2)^2

Evaluate the expression

A = 189.97 mm^2

Hence, the area of the semicircle with the given diameter is 189.97 mm^2

Using the hypergeometric distribution, there is a 0.1786 = 17.86% probability that Ryan beats Matt in a landslide by choosing 3 Paper cards in a row.

The formula is:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

For this problem, we have that Ryan will win if he takes 3 Paper cards from a set of 8(5 paper and 3 scissors), hence the parameters are given as follows:

N = 8, k = 5, n = 3, x = 3.

Hence the probability is given by:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 3) = h(3,8,3,5) = \frac{C_{5,3}C_{3,0}}{C_{8,3}} = 0.1786[/tex]

0.1786 = 17.86% probability that Ryan beats Matt in a landslide by choosing 3 Paper cards in a row.

The new coordinates are A'(-21, 7), B'(0, -28), C'(14, 28).

Dilating the given triangle by the scale factor means multiplying each coordinate by the given scale factor.

Given coordinates are A(-3, 1), B(2, 4), and C(0, -4).

The scale factor k = 7.

Let, the new coordinate obtained by dilating A with scale factor k be A'.

Then x-coordinate of A' = k × x-coordinate of A

⇒ x-coordinate of A' = 7 × (-3)

⇒ x-coordinate of A' = -21

And y-coordinate of A' = k × y-coordinate of A

⇒ y-coordinate of A' = 7 × 1

⇒ y-coordinate of A' = 7

So, A' → (-21, 7)

Let, the new coordinate obtained by dilating B with scale factor k be B'.

Then x-coordinate of B' = k × x-coordinate of B

⇒ x-coordinate of B' = 7 × 2

⇒ x-coordinate of B' = 14

And y-coordinate of B' = k × y-coordinate of B

⇒ y-coordinate of B' = 7 × 4

⇒ y-coordinate of B' = 28

So, B' → (14, 28)

Let, the new coordinate obtained by dilating C with scale factor k be C'.

Then x-coordinate of C' = k × x-coordinate of C

⇒ x-coordinate of C' = 7 × 0

⇒ x-coordinate of C' = 0

And y-coordinate of C' = k × y-coordinate of C

⇒ y-coordinate of C' = 7 × -4

⇒ y-coordinate of C' = -28

So, C' → (0, -28)

Refer to the image attached for the new triangle formed.

Therefore, the new coordinates are A'(-21, 7), B'(0, -28), C'(14, 28).

The negatives on a number line are on the left side and the positives on the right.

Step-by-step explanation: educated guess

Answer:

B. y = -1/4x + 2

Step-by-step explanation:

The slopes of two perpendicular lines are negative reciprocals of each other. So slope is -1/4

Using m = -1/4, y =4, x = -8

y = mx + b

4 = -1/4(-8) + b

4 = 2 + b

b = 2

so y = -1/4x + 2

The probability that a hand of five cards chosen at random and without replacement from a standard 52 card deck will have a king of spades, exactly one other king, and exactly two queens = 0.000332

A deck of cards consist of 52 cards in which each 13 cards are from 4 suits: Spades, Hearts, Diamonds and Clubs.

Each suit consist of cards Ace, King, Queen, Jack and other 9 cards.

So in 52 cards there is 4 kings and 4 queens each.

Five cards are selected at random and without replacement.

Five cards from a 52 deck cards can be chosen in 52C5 ways.

A spade king can be chosen in 1C1 way. [ Since there is only one spade king]

Exactly one other king can be chosen in 3C1 ways. [Since now only 3 kings are remaining after choosing 1 spade king]

Exactly 2 queens can be chosen in 4C2 ways.

Now 4 cards are selected out of 5. The remaining 1 card is chosen out in 48C1 ways.

So the probability that the five cards chosen will have a king of spades, exactly one other king, and exactly two queens

                           = (1C1 x 3C1 x 4C2 x 48C1) /52C5 = 18/54145 =0.000332

Answer:

y-intercept : 3

x-intercepts are 1 and 2

Vertex is at (2,-1)

Axis of symmetry is at x = 2

Step-by-step explanation:

See attached graph.

The equation y = x² – 4x + 3 represents a parabola

y-intercept at is at B(0,3); y-intercept is 3

x-intercept points at C(1,0) and D(3,0) so x-intercepts are 1 and 3

The vertex is the lowest point on this parabola (2-1)

Axis of symmetry is a line passing through the vertex and dividing the parabola into two equal halves. This is the vertical line x = 2

The correct option is A. {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)}.

The function which also has an inverse that is also a function is {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)}.

An inverse in mathematics is a function which serves to "undo" another function. That is, if f(x) yields y, then placing y into the inverse of f yields x.

In response to the given question

We understand that such a function is really only one that has a unique y value that corresponds to x.

An inverse function is only a function is if function being inversed is also a function.

Thus, option (A) has all x corresponding to y values that are different, but all remaining options have the values repeating, so that will not be a function because only (A) has to inverse.

The height of the boat floating above the seafloor at high tide is 17.5 feet.

In this question, we have been given a boat which is anchored in the water.

At low tide, the boat is floating 20 feet above the seafloor and is a horizontal distance of 40 feet away from its anchor.

And at high tide, the boat is a horizontal distance of 35 feet away from its anchor.

We need to find the distance the boat floating above the seafloor at high tide.

Consider the following diagram.

Let the boat floating m feet above the seafloor when the boat is a horizontal distance of 35 feet away from its anchor.

Since both the triangle are similar triangles, the corresponding sides must be in proportion.

⇒ 20/40 = m/35

We need to find the value of m.

⇒ 20 × 35 = m × 40

⇒ m = 35 / 2

⇒ m = 17.5 feet

Therefore, the height of the boat floating above the seafloor at high tide is 17.5 feet.

You can calculate the Car Loan EMI Amount with the help of the mathematical formula: EMI Amount = [P x R x (1+R)^N]/[(1+R)^N-1] , where P, R, and N are the variables. This also means that the EMI value will change, each time you change any of the three variables. Let’s discuss these three variables in detail.

‘P’ stands for the Principal Amount. It is the original loan amount given to you by the bank on which the interest will be calculated.

‘R’ stands for the Rate of Interest set by the bank.

N is the number of years given for the repayment of the loan. As you must pay the EMIs each month, the duration is calculated in the number of months.

Here , P=$50000,R=3/12/100=0.0025,N=36 Months.

EMI=[50000 x 0.0025 x (1+0.0025)^36]/[(1+0.0025)^36-1]
