Answer:

7 red marbles

Step-by-step explanation:

P( red) = red marbles / total marbles = 1/8

We know there are 56 marbles

red marbles/56 = 1/8

Multiply by 56

red marbles = 1/8 *56 = 7

There are 7 red marbles

Answer: Distance is 17

Step-by-step explanation:

[tex]d = √((x2-x1)2 + (y2-y1)2)[/tex]

[tex](x2-x1) = (2 -6) = 8[/tex]

[tex](y2-y1) = (17 - 2) = 15[/tex]

Add them all together

[tex](8)2 + (15)2 = 64 + 225 = 289[/tex]

Square 289

[tex]\sqrt{289} =17[/tex]

Answer:

0.64

Step-by-step explanation:

4 out of 5 free throws is 0.8 as a decimal.

The probability that Brian will make 2 free throws is 0.8 for the first one, and then 0.8 of that for the second one. That means you multiply the two to get your answer and 0.8 times 0.8 = 0.64.

Answer:

224 points.

Step-by-Step Explanation:

We know that Andrew scores 16 points per basketball game.

He continues scoring the same amount of points for 14 more games.

Therefore, the total amount of points he will score in total will be 16 multiplied by 14.

Since 16 times 14 is 224, this means that Andrew will score 224 points in total.

Answer:

d None of these choices are correct.

Step-by-step explanation:

In ΔRED and ΔTAN

∠R ≅ ∠T... (given)

∠E ≅ ∠A... (given)

ED ≅ AN... (required)

Therefore, ED ≅ AN is needed to prove ΔRED ≅ ΔTAN by AAS Postulate.

Answer: 40 stamps

Step-by-step explanation:

Let Maddy = M and Simon = S

Given that maddy had twice as many stamps as simon. That is,

M = 2S ....(1)

After maddy sold 60 stamps, simon had twice as many stamps as maddy. That is,

S = 2( M - 60) .... (2)

Substitutes M for 2S from equation (1) into equation (2)

S = 2( 2S - 60 )

Open the bracket

S = 4S - 120

Collect the like terms

S - 4S = -120

- 3S = - 120

S = 120/3

S = 40

Substitute S into the equation (1)

M = 2 × 40 = 80

Maddy has 80 - 40 = 40 stamp

Therefore, Maddy has 40 more stamps than simon in the beginning.

Answer:

In equal roles, men and women will establish more meaningful marriages.

Step-by-step explanation:

Marry Wollstonecraft in her feminist philosophy "A Vindication of the Rights of Woman" had projected the idea of equalizing the rights of men and women. She builds her argument against the theorists who do not consider education to be important for the female gender of the society. She presents her point by giving instances of how the education of women is indirectly related to the upliftment of the entire society. Wollstonecraft urges for equal fundamental rights to be shared by both men and women. An educated woman not just helps to become a good 'companion' of her husband but also raises her children in an efficient way.

Answer:

The correct option is;

A. 90 degrees clockwise rotation

Step-by-step explanation:

From the given information, we have;

The coordinates of the pre-image is K(-6, 9)

The coordinates of the image is k'(9, 6) which is similar to a transformation of a pre-image of (x, y) to an image of (y, -x)

The transformation from (x, y) to (y, -x) can be obtained from either;

1) A rotation of 90° (clock wise)

2) A rotation of 270° counter clockwise

Therefore, the correct option that maps K(-6, 9) to K'(9, 6) is a 90 degrees clockwise rotation.

Answer: The person above me is correct!  A. 90 degrees clockwise rotation

Answer:

y = - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{3}{4y+2}[/tex]

The denominator of the expression cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that y cannot be, that is

4y + 2 = 0 ( subtract 2 from both sides )

4y = - 2 ( divide both sides by 4 )

y = [tex]\frac{-2}{4}[/tex] = - [tex]\frac{1}{2}[/tex] ← excluded value

Answer:

Step-by-step explanation:

When it says "double", you are multiplying by 2.

Answer:

The three trigonometric ratios can be used to calculate the size of an angle in a right-angled triangle

Use rule ; SOHCAHTOA .Where sin x = opp/hyp

cos x = adj/hyp

tan x= opp/adj

Substitute the given values for the three sides

into any of the above rules

[tex]example = Hyp = 2\\opp = 1\\sin- x = 1/2\\x = sin^{-1} 1/2\\x = 30[/tex]

Answer:

[tex](25x + 8)(x + 2)[/tex]

Step-by-step explanation:

[tex]25x^{2} + 58x + 16 = 25x^{2} + 50x + 8x + 16 = 25x(x + 2) + 8(x + 2) = (25x + 8)(x + 2)[/tex]

Answer:

A

Step-by-step explanation:

First, let's do the difference of two squares:

[tex](1-cos^4(\theta))=(1-cos^2(\theta))(1+cos^2(\theta))[/tex]

Note that [tex]sin^2(\theta)=1-cos^2(\theta)[/tex] (Pythagorean Identity)

Thus, we can substitute:

[tex]sin^2(\theta)(1+cos^2(\theta))[/tex]

Now, and I'm serious, you just have to use your creativity. After a while, you will find that:

[tex]sin^2(\theta)+cos^2(\theta)=1[/tex]

So:

[tex]1+sin^2(\theta)+cos^2(\theta)=1+1[/tex]

Thus, we have [tex]1+cos^2(\theta)=2-sin^2(\theta)[/tex]

Now, we can substitute:

[tex]sin^2(\theta)(2-sin^2(\theta))=2sin^2(\theta)-sin^4(\theta)[/tex]

Answer:

0.0471

Step-by-step explanation:

Here, we want to find the area of the shaded region.

The area of the shade region = 1- area of the unshaded region

The area of the unshaded region is as follows;

P(b) - P(a)

and that is;

P(-1.88<x<2.12) = 0.95294 from z table

So the area of the shaded region = 1-0.95294 =

0.04706 = 0.0471 to 4 d.p

Answer:

47%

Step-by-step explanation:

The total number of student is 4+6+2+2+3+4+6+3 = 30 students

P( male) = male / total

              = (4+6+2+2)/ total

               =14/30

                =.466666666

                46.66666%

To the nearest whole percent

                 47%

Answer:

$7.89

Step-by-step explanation:

There are 36 possible outcomes when rolling two dice.

The sum will be odd if the first die is odd and the second is even or if the second is odd and the first is even. The probability of an odd sum is:

[tex]P(odd)=\frac{3}{6} *\frac{3}{6} +\frac{3}{6} *\frac{3}{6}\\P(odd)=0.5[/tex]

There is a probability of 1 in 2 of winning $10.

There are 8 ways to get a sum of 4 or 8 (1,3; 3,1; 2,2; 5,3; 3,5; 2,6; 6,2; 4,4). There is a probability of 8 in 36 or 2 in 9 of winning $5.

There are 2 ways to get a sum of 2 or 12 (1,1; 6,6). There is a probability of 2 in 36 or 1 in 18 of winning $50.

Any other outcome will not payout any amount.

The expected value is the sum of all possible payouts multiplied by their likelihood (including a 100% chance of paying $1 to play).

[tex]E=-1+10*\frac{1}{2} +5*\frac{2}{9}+50*\frac{1}{18}\\E=\$7.89[/tex]

The expected value is $7.89.

Answer:

$11

Step-by-step explanation:

[tex]\left\begin{array}{c|ccc}&$Lose \$25&$Gain \$5&$Gain \$45\\$Stock ABC&40\%&15\%&45\%\end{array}\right[/tex]

We want to calculate the expected gain or loss of Stock ABC with the probabilities above.

Note that loss is written in negative.

[tex]E$xpected Value =$ (-25 \times 40\%)+(5 \times 15\%) + (45 \times 45\%)\\=(-25 \times 0.4)+(5 \times 0.15)+(45 \times 0.45)\\=-10+0.75+20.25\\=\$11[/tex]

Stock ABC has an expected gain of $11.

Hey there! :)

Answer:

25 pieces.

Step-by-step explanation:

To solve for the amount of pieces that can be cut, we must divide fractions:

15 ÷ 3/5 = x

When dividing fractions, you must multiply by the reciprocal. Therefore:

[tex]\frac{15}{1}* \frac{5}{3} = \frac{75}{3} = 25[/tex]

Therefore, 25 pieces can be cut.

Answer:

25 3/5 inch long pieces

Step-by-step explanation:

If you have 15 inches and you cut it into less than inch pieces, you know for sure that it will be more than 15 but less than 30 because the peices are more than half an inch.

to find the answer, you divide 15 by 3/5 because each piece is 3/5 inches long

when you put this into a calculator 15/(3/5) you will get the answer 25.

So, ANSWER = 25 pieces of rope that are 3/5 inches long

Hope this helps and you will understand if you face a problem similar to this :)

Answer:

Rectangular fence dimensions:

x = 14 ft

w = 7  ft

A  = 98 ft²

Step-by-step explanation:

Rectangular fence dimensions:

x   length      and     w  width

Then   x  =  2*w      ⇒     w = x/2

Perimeter is

p = 2*x + 2*w

p = 2*x + 2* x/2

p = 2*x + x

3*x = 42

x = 14  ft      and     w = 14/2      ⇒     w = 7  ft

you can graph the points. i recommend using Desmos

Step-by-step explanation:

As for the line of best fit you can use snaggit or snipping tool and both can help with the graph.

for the residual, you need to calculate the actual value minus the predicted value.

you should be given a formula in your problem.... that is for the predicted value.
