What is the probability of landing on a color other than green?


Enter your answer as a fraction, like this: 42/53

Answers

Answer:

2/3

Step-by-step explanation:

so, you have a circle and if you divide it into 3 equal sections each of those sections take only 1/3 of the circle.

1/3 + 1/3 + 1/3 = 1

if one of the thirds is green then the probability of it landing on another color would be 2/3 being the other two colors.

One number is 3 less than 4 times a second number. The difference of the first number and twice the second number is 7. What are the two numbers?

Answers

Answer:

x = -11, y = -2

Step-by-step explanation:

There's two equations. Let's say the first number is x, and the second number is y. Then, there is 4y-3 = x, and 2y-x = 7. We plug in 4y-3 for x into the second equation, and we get 2y - (4y-3) = 7. Solving more gets us -2y + 3 = 7. thus, -2y = 4, meaning y = -2. We plug back into the second equation, getting -4 - x = 7. This 11 = -x, or x = -11.

Step-by-step explanation:

A, B, and D are all 5.5 and C alone is 5.2

Answer:

C is the odd one.

Step-by-step explanation:

Let's verify each option.

Option A

44/8 = 40/8 + 4/8 = 5 1/2 = 5 + 0.5 = 5.5

Option B

5 1/2 = 5 + 0.5 = 5.5

Option C

5 1/5 = 5 + 0.2 = 5.2

Option D

5.500 = 5.5

Looking at the options, we can see that the result of Option A, B, and D are same.

This means that the odd one is Option C.

The dot plots show the number of points that Sophia and Valerie each scored in the first 10 basketball games. The mean for Sophia's Basketball is 8. 5 points and the mean for Valerie's Basketball games is 15. 5 points. The mean absolute deviation of both distributions is 2 points

Part A: The mean number of points scored by Valerie is 2 or 7 or 8. 5 or 15. 5 greater than the mean numbers of points scored by Sophia.

Part B: What multiple of the mean absolute deviation represents the difference in the mean number of points scored by Sophia and Valerie in the first 10 basketball games?

2. 5

3. 5

4. 0

Answers

The mean number of points scored is the average of points scored

The mean number of points scored by Valerie is 7 greater than the mean numbers of points scored by Sophia.

How to interpret the mean?

The given parameters are:

Mean for Sophia's = 8.5 pointsMean for Valerie's = 15.5 points. Mean absolute deviation of both = 2 points

Calculate the difference (d) between the mean values

d = 15.5 - 8.5

Evaluate the difference

d = 7

Hence, the mean number of points scored by Valerie is 7 greater than the mean numbers of points scored by Sophia.

The multiple of the mean absolute deviation?

In (a), we have:

Mean absolute deviation of both = 2 points

Difference  = 7

Express as products

Difference = 2 * 3.5

Hence, 3.5 is a factor of the difference between the mean

Find the 95th term of the arithmetic sequence 4, -5, -14

Answers

Answer: -842

Step-by-step explanation:

To find n95, we have to use the equation aₙ = d * n + a₁ - d

a₁ is the first term, which here is 4. d is the common difference, which we can find out but seeing what we can add pr subtract from 4 to -5 which also equals -5 to -14, in this equation, the common difference would be -9 as it goes down by 9 every term. Once we plug these into the equation, we get

a₉₅ = -9 * n + 4 - (-9)

We can solve this for - aₙ = -9n + 13

Now that we have our equation to find a term, we can plug in n for 95 for

-9(95) + 13

~

Answer:

-2

Step-by-step explanation:

In the question we have given with an equation that is 14 + 5x = 3 ( -x + 3 ) - 11 .

And we are asked to find the value of x.

Solution : -

[tex] \longmapsto \: 14 + 5x = 3( - x + 3) - 11[/tex]

Step 1 : Solving parenthesis on right side :

[tex] \longmapsto \: 14 + 5x = - 3x + 9 - 11[/tex]

On further calculations we get :

[tex] \longmapsto \: 14 + 5x = - 3x - 2[/tex]

Step 2 :

Subtracting 14 from both sides :

[tex] \longmapsto \: \cancel{14} - \cancel{14 }+ 5x = -3x -2 - 14[/tex]

On further calculations we get :

[tex] \longmapsto \: 5x = - 3x - 16[/tex]

Step 3 : Adding 3x on both sides :

[tex] \longmapsto \: 5x + 3x = - \cancel{ 3x} + \cancel{3x} - 16[/tex]

On further calculations we get :

[tex] \longmapsto \: 8x = - 16[/tex]

Step 4 : Dividing by 8 on both sides :

[tex] \longmapsto \: \frac{ \cancel{8}x}{ \cancel{8}} = \cancel {\frac{ - 16}{8} }[/tex]

We get :

[tex] \longmapsto \: \red{\boxed{ \mathfrak{x = - 2}}}[/tex]

Therefore , value of x is -2 .

Verifying :

We're verifying our answer by substituting value of x in given equation . So ,

14 + 5x = 3 ( -x + 3 ) - 11

14 + 5 ( - 2 ) = 3 { -( -2 ) + 3 ) - 11

14 - 10 = 3 ( 2 + 3 ) - 11

4 = 3 ( 5 ) - 11

4 = 15 - 11

4 = 4

L.H.S = R.H.S

Hence , Verified .

Therefore , our value for x is valid .

Equation: y = 4x + 6

x + y = 95. and y is 2/3 of x. find x and y.​

Answers

Answer:

{x,y}={60,35}

Step-by-step explanation:

// Solve equation [2] for the variable  x

 [2]    x = y + 25

// Plug this in for variable  x  in equation [1]

  [1]    (y +25) + y = 95

  [1]    2y = 70

// Solve equation [1] for the variable  y

  [1]    2y = 70

  [1]    y = 35

// By now we know this much :

   x = y+25

   y = 35

// Use the  y  value to solve for  x

   x = (35)+25 = 60

Answer:

x=57

y=38

Step-by-step explanation:

(1): x+y=95

(2): y=2/3x

substitute y=(2/3)x in equation (1):

x+(2/3)x=95

Multiply both sides by 3

3x+2x=285

5x=285

Divide both sides by 5

x=285/5

x=57

substitute x=57 in equation (2):

y=2/3×57=38

hence: x=57 , y=38

A wire is in the shape of a rectangle of length 14cm. Find its breadth if the same wire is re- bent into a square of side 13cm. Also find out their areas and write which one encloses more area, the rectangle or square.

Answers

Length= 40cm

Breadth= 22cm

Perimeter of the rectangle= Length of the wire

Now, the wire is rebent into a square.

Perimeter= 124cm

4\times side=124

Therefore side= \frac{124}{4}cm= 31cm

So, the measure of each side= 31cm
