Answer:

1/3

Step-by-step explanation:

the probability of the first is 6/10 or simplified 3/5

she then repeats its without putting the marble back 5/9 (as she has to remove a green marble)

to find the odds multiply 5/9 and 3/5 you get 15/45 reduced to 1/3, so the probability is 1/3

Answer:

[tex]2\frac{1}{3}[/tex], [tex]\sqrt{7}[/tex], [tex]\sqrt[3]{27}[/tex]

Step-by-step explanation:

If you want to make ordering these three numbers to be easier, it's best to find their exact or approximate values. [tex]\sqrt[3]{27}[/tex] is equivalent to 3, and [tex]\sqrt{7}[/tex] is less than [tex]\sqrt{9}[/tex] - which is 3 - so you know that [tex]\sqrt[3]{27}[/tex] is going to be the greatest number out of the set. Since [tex]\sqrt{7}[/tex] is approximately equal to 2.65, and [tex]2\frac{1}{3}[/tex] is approximately equal to 2.33, you can conclude that the correct order from least to greatest is going to be [tex]2\frac{1}{3}[/tex], [tex]\sqrt{7}[/tex], [tex]\sqrt[3]{27}[/tex].

Answer:

Mean=8.8, Median=8

Step-by-step explanation:

How to find the mean:

First, add all the #'s up. 4+9+12+14+7+7=53

Then divide that by the number or numbers. In this case it is 6.

53/6=8.833... So rounded=8.8

Median:

List numbers lowest to highest

4, 7, 7, 9, 12, 14

Go to the middle number.

Since it is between 7 and 9, it is 7+9=16. 16/2=8

8 is the median

William can run 10 laps in one hour with 4/15 same pace.

We have,

William ran 2 2/3 laps around a track in of an hour.

William keeps the 4/15 same pace.

So, William runs

= 2 2/3 ÷ (4/15)

= (8/3)÷ (4/15)

= 8/3 x 15/4

= 2 x 5

= 10 laps.

Thus, William runs 10 laps.

Answer:

mean = 33

Step-by-step explanation:

37 = mean + 2sd

37 = mean + mean - 29

mean = 66/2 = 33

Answer:

cos theta = 5/13

Step-by-step explanation:

sin theta = opp side / hypotenuse

opp side = 12   and hypotenuse = 13

Using the pythgorean theorem

opp ^2 + adj ^2 = hypotenuse ^2

12 ^2 + adj^2 = 13^2

144 + adj ^2 = 169

adj^2 = 169-144

adj^2 = 25

Taking the square root of each side

adj = 5

cos theta = adj / hypotenuse

cos theta = 5/13

Answer:

20√3/3 or approx. 11.55 in.

Step-by-step explanation:

Draw an equilateral triangle with one height to one side.

The height divides the triangle into two congruent right triangles.

At the vertex where the height is, each angle of the small triangles is 30 deg.

The other acute angle of the right triangle measures 60 degrees.

The two right triangles are 30-60-90 right triangles.

The ratio of the lengths of the sides of a 30-60-90 right triangle is

1 : √3 : 2

The height is opposite the 60-deg angle, so it corresponds to the side with length √3 in the ratio.

The long leg measures 10.

The short leg measures 10/√3 = 10√3/3

The hypotenuse measures 20√3/3

The side of the equilateral triangle is the hypotenuse of each small right triangle.

Answer: 20√3/3 or approx. 11.55 in.

3 red,           3 blue,       3 green

that all adds to 9 marbles and there are 3 out of 9 marbles that are green.

the probability is 3/9 or 1/3

Step-by-step explanation:

you understand how a venn diagram works ?

you have to put elements or the amount of elements into the different segments. there are segments that belong to only one category, segments with elements that are shared between 2 neighboring categories, and in this case 1 segment in the middle that has all elements shared between all 3 categories.

so, we know, the total of all elements (fans) is 36.

now imagine we place every fan exactly into the segment, where his or her allegiance lies.

the easiest way to start is with the center. there are 5 fans there, so write 5 in there.

these 5 people are therefore also part of the total number of Wild fans, of the Viking fans and the Twins fans, and of all the shared segments, of course.

so, we have only 7-5 = 2 shared Wild and Vikings only fans (in the segment above the center segment). they are not fans of the Twins.

we have 9-5 = 4 shared Wild and Twins only fans (in the segment left below the center). they are not fans of the Vikings.

we have 11-5 = 6 shared Vikings and Twins only fans (in the segment right below the center). they are not Wild fans.

what is left for the pure, single team fans ?

the Wild have 12-5-2-4 = 1 pure fan.

the Vikings have 16-5-2-6 = 3 pure fans.

the Twins have 22-5-4-6 = 7 pure fans.

so, we have 1+3+7 = 11 pure fans, 2+4+6 = 12 double team fans, and 5 all 3 teams fans. but that is only 28 fans altogether.

so, something is not right with the data here.

I assume we have 28 total from now on.

for Viking AND Wild fans we have the 2 fans that only like these 2 teams plus the 5 that like all 3 teams (including the Vikings and the Wild) = 7 out of the total of 28 fans.

the probability to pick one of them is then

7/28 = 1/4 =0.25

if the total of 36 questioned fans is still there and explained maybe outside of the given venn diagram (e.g. were asked but are fans of a totally different team or of no team at all), then the probability would be

7/36 = 0.194444444...

Step-by-step explanation:

Theoretical probability describes how likely an event is to occur. We know that a coin is equally likely to land heads or tails, so the theoretical probability of getting heads is 1/2. Experimental probability describes how frequently an event actually occurred in an experiment.

EXAMPLE-

Theoretical probability:

For instance, since a flipped coin has two sides and each side is equally likely to land up, the theoretical probability of landing heads (or tails) is exactly 1 out of 2.

Experimental probability:-

For example, the probability of getting a head if you flip a coin is ½, since only 2 things could happen (a head or a tail) and each one has an equal chance of occurring.

The sample size is, 9604 if you want to obtain a sample to estimate a population proportion at this point in time, you have no reasonable estimate for the population proportion.

It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.

As we know, the sample size can be evaluated using the expression:

[tex]\rm ME = Z_c\sqrt{\dfrac{pq}{n}}[/tex]

or

[tex]\rm n = \dfrac{Z^2}{ME^2}(pq)[/tex]

Here ME = 1% = 0.01

p = 0.5, q = 0.5

Z at α 0.05   (because 95% confident)

= 1.960  

[tex]\rm n = \dfrac{1.960^2}{0.01^2}(0.5\times0.5)[/tex]

n = 9604

Thus, the sample size is, 9604 if you want to obtain a sample to estimate a population proportion at this point in time, you have no reasonable estimate for the population proportion.

Delaney  solve for X by isolating it,  or getting it by it self

Step-by-step explanation:

5x−2(x+1)=1/4 (distribute the 2)

5x-2x - 2 = 1/4  (subtract 2x from 5x)

3x -2 +2 = 1/4 +2 (add 2 to both sides)

3x = 2_1/4  (put 2 &  1/4 together)

3x = 9/4 (convert 2_1/4 to  9/4)

[tex]\frac{1}{3}[/tex]*3*x =  [tex]\frac{1}{3}[/tex]*[tex]\frac{9}{4}[/tex]  ( mutilply both sides by  1/3)

X = 3/4   (cross multiply )

There you go

X = [tex]\frac{3}{4}[/tex]

Answer:

[tex]\huge\boxed{\bf\:x = \frac{3}{4}}[/tex]

Step-by-step explanation:

[tex]5x - 2(x+1)=\frac{1}{4}[/tex]

Use the distributive property for 2(x + 1).

[tex]5x - 2x - 2= \frac{1}{4}[/tex]

Subtract 2x from 5x.

[tex]3x - 2= \frac{1}{4}[/tex]

Bring 2 to the right hand side of the equation .

[tex]3x = \frac{1}{4} + 2[/tex]

Add 1/4 & 2.

[tex]3x = \frac{1}{4} + \frac{8}{4} \: \: [LCM = 4]\\3x = \frac{9}{4}[/tex]

Now, bring 3 to the right hand side of the equation .

Answer:

[tex]\csc \left(\dfrac{4\pi}{3}\right)=-\dfrac{2}{\sqrt{3}}[/tex]

Step-by-step explanation:

[tex]\phi=\dfrac{4 \pi}{3}[/tex]

Therefore, this angle lies in quadrant III since it is between π and 3π/2

It's reference angle is:

[tex]\dfrac{4 \pi}{3}-\pi=\dfrac{\pi}{3}[/tex]

and so lies in quadrant I

[tex]\csc (\phi)=\dfrac{1}{\sin(\phi)}[/tex]

For sine, quadrant I and II are positive and quadrant III and IV are negative.

Therefore, as  [tex]\sin \dfrac{\pi}{3}=\dfrac{\sqrt{3}}{2}[/tex]  then [tex]\sin \dfrac{4\pi}{3}=-\dfrac{\sqrt{3}}{2}[/tex]

Finally,

[tex]\csc \left(\dfrac{4\pi}{3}\right)=\dfrac{1}{\sin\left(\dfrac{4\pi}{3}\right)}[/tex]

[tex]\implies \csc \left(\dfrac{4\pi}{3}\right)=\dfrac{1}{-\dfrac{\sqrt{3}}{2}}[/tex]

[tex]\implies \csc \left(\dfrac{4\pi}{3}\right)=-\dfrac{2}{\sqrt{3}}[/tex]

[tex]\\ \rm\Rrightarrow csc\dfrac{4\pi}{3}[/tex]

[tex]\\ \rm\Rrightarrow csc\left(\pi +\dfrac{\pi}{3}\right)[/tex]

Applying the definition of the diagonals of a rhombus, the value of m is -3, and the value of c is 26.

The diagonals of a rhombus are perpendicular to each other and therefore have slopes that are negative reciprocals.

Equation of diagonal DB is, y = 1/3x + 5.

Slope (m) of DB is 1/3.

Therefore, the slope (m) of diagonal AC would be, -3.

To find the equation of diagonal AC, substitute m = -3 and (5, 11) = (a, b) into y - b = m(x - a)

y - 11 = -3(x - 5)

y - 11 = -3x + 15

y = -3x + 15 + 11

y = -3x + 26
