Then the number of the ways that the medals can be awarded will be 165. Then the correct option is D.

A permutation is an act of putting things or elements in the right sequence. Combinations are a method of picking things or pieces from a collection of objects or sets when the sequence of the objects is irrelevant.

There are 11 runners in a race. Medals are awarded for 1st, 2nd, and 3rd place.

Then the number of the ways that the medals can be awarded.

When the first two terms and the last two terms are grouped, the common binomial factor is 6x – 7

30x² – 35x + 54x – 63

Group the first two and the last two terms

(30x² – 35x) + (54x – 63)

Factorise

5x(6x – 7) + 9(6x – 7)

Common factor => 6x – 7

Using the percentage concept, it is found that 1 serving of walnuts provides 10% of daily calories.

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

[tex]P = \frac{a}{b} \times 100\%[/tex]

In this problem, one serving has 21 grams, each with 10 calories, hence the number of calories is given by:

C = 21 x 10 = 210 calories.

Hence, out of a 2,100 calorie diet, the percentage is given by:

[tex]P = \frac{210}{2100} \times 100\% = 10\%[/tex]

Step-by-step explanation:

all bags are mislabeled. that means, whatever is written on either of the 3 bags, is wrong.

so, the bag labeled "green" is NOT the one with 2 green apples. the one labeled "red" is NOT the one with 2 red apples.

and - my favorite - the one labeled "red/green" is NOT the one with the mixture.

so, we pick one apple from the bag that is currently (mis-)labeled as "red/green".

as it cannot be the mixed bag, it must be one of the pure color bags.

whatever color shows up, we know this is the bag with 2 apples of that color.

then the bag that was labeled with that color must be the other pure color (if it were the mixed bag, it would mean that the third bag was labeled correctly, which is not the case). and then the third bag is the mixed one.

for example :

we get a red apple in our first pick.

so, the bag, that was originally (but wrongly) labeled as "red/green" gets the label "red".

then the bag with the original (but again wrong) label "green" gets now the label "red".

and the third bag with the original (but wrong) label "red" gets the "red/green" label.

if the first apple is green, then the same principle just with reversed colors applies.

The model for representing the ratio of the number of orange and green rolls are [tex]\dfrac{3}{2}[/tex]

A model that shows the number of orange and green streamers needed to decorate 3 dorm rooms will be 3O=2G

The ratio is defined as the representation of the one number with respect to the other number. or one number is how many times to the other number.

A model that represents the ratio of different colored streamers.

[tex]\dfrac{3}{2}=\dfrac{O}{G}{[/tex]

A model that shows the number of orange and green streamers needed to decorate 3 dorm rooms.

Answer:

So looking at the expression that was given to us, we know that we must solve for g.  In order to solve for g we need to make sure that g is alone on one side of the expression.  In this example, we need to multiply both sides by 4 to get rid of the fraction on the left and in effect we would multiply 12 by 4 also.

[tex]\frac{g}{4} > 12[/tex]

[tex]\frac{g}{4}*4 > 12*4[/tex]

[tex]g > 48[/tex]

Therefore, our final answer is [tex]g > 48[/tex]

The sequence 4, 20, 36, 52, Required 6th term is 84.

A sequence is an enumerated group of objects in mathematics where repetitions are permitted and order is important. Similar to a set, it has members (also called elements, or terms). The length of the sequence is the number of elements (possibly infinite). In contrast to a set, the same elements can appear more than once in a sequence at various positions, and unlike a set, the order is important. The formal definition of a sequence is a function from natural numbers to the elements in each position. An indexed family, which is a function from any index set, can be thought of as a generalisation of the idea of a sequence.

For instance, the letters (M, A, R, Y) are arranged with M coming first and Y coming last.

Given, sequence is an arithematic sequence with common difference 16 and first term 4.

So,

6th term = first term + 5 * common difference

               = 4 + 5 * 16

               = 84

Hence, the required 6th term is 84.

Answer:

[tex]\displaystyle V = \pi \int_0^{1.835}\left[ 4 - y^2\right]^2 - \left[ 4-\sqrt{4(y+1)}\right]^2\, dy[/tex]

Step-by-step explanation:

We can use the washer method. Because the axis of revolution is vertical, our representative rectangle is horizontal. Recall that:

[tex]\displaystyle V = \pi \int_a^b \left[ R(y)\right] ^2 - \left[r(y)\right]^2 \, dy[/tex]

Solve each equation as a function of y:

[tex]\displaystyle \begin{aligned} y & = \sqrt{x} \\ \\ x_1 & = y^2\end{aligned}[/tex]

And:

[tex]\displaystyle \begin{aligned} y & = \frac{1}{4}x^2 - 1 \\ \\ x_2 & = \pm\sqrt{4(y+1)} \\ \\ & = \sqrt{4(y+1)}\end{aligned}[/tex]

The outer radius R is simply (4 - x₁) and the inner radius r is (4 - x₂). The point of intersection is (3.368, 1,835), so our limits of integration are from y = 0 to y = 1.835.

Therefore, the integral that represents the region being revolved around

x = 4 is:

[tex]\displaystyle V = \pi \int_0^{1.835}\left[ 4 - y^2\right]^2 - \left[ 4-\sqrt{4(y+1)}\right]^2\, dy[/tex]

Answer:

Step-by-step explanation:

What is the rule for a reflection across the Y axis? The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same

Answer:

  A'(-2, 5)

  B'(-6, 3)

Step-by-step explanation:

When a point is reflected in the y-axis, the image is as far from the y-axis on the other side as the original point is on this side. That is, the y-axis is halfway between the original point and its image. The x-coordinate of a point measures how far from the y-axis it is, so reflection in the y-axis changes the sign of the x-coordinate:

  (x, y) ⇒ (-x, y) . . . . . reflection in the y-axis

__

  A(2, 5) ⇒ A'(-2, 5)

  B(6, 3) ⇒ B'(-6, 3)
