A spinner with 8 equal-sized sections is used for a game. Based on the descriptions below, is the spinner fair? Explain. The probability the pointer will land on yellow is 1 out of 4. The probability the pointer will land on blue is 2 out of 8. The probabilities that the pointer will land on green or red are both 25%.

Answer:

Step-by-step explanation:

(2x) + (3x+5) = 90°

5x = 85°

x = 17°

Answer:

See below.

Step-by-step explanation:

Party A

y = x^2 + 1

For each value of x in the table, substitute x in the equation with that value and evaluate y.

x = -2: y = (-2)^2 + 1 = 4 + 1 = 5

x = -1: y = (-1)^2 + 1 = 1 + 1 = 2

Do the same for x = 0, x = 1, x = 2

x     y

-2   5

-1    2

0    1

1     2

2    5

Part B

Look at points (-2, 5) and (-1, 2). The change in x from (-2, 5) to (-1, 2) is 1. The change in y is -3.

Now let's look at two other points which have a change in x of 1. Look at points (0, 1) and (1, 2). The change in x from (0, 1) to (1, 2) is 1. The change in y is 1.

You can see that for the first two points, a change of 1 in x produces a change of -3 in y, but for the second two points, the same change of 1 in x produce a change of 1 in y. Since the same change of x does not always produce the same change in y, the function is nonlinear.

Answer: A

Answer:

x=5.9

Step-by-step explanation:

First, you want to isolate x so you have to subtract 31.7 from both sides. This will make the equation -3x=-17.7. Because they are both sides are negative, you can change both sides to positive so it will be 3x=17.7. Next, you want x to be 1 so you have to divide 3 in both sides. This will make the equation x=17.7/3. Simplify that to get x=5.9.

Answer:

396π.cm^3

Step-by-step explanation:

ere's your solution

=> height of cylinder = 11 cm

=> radius of cylinder = 6 cm

=> volume = πr^2h

=> putting the value of radius and height in formula

=>volume = 6^2*11 π

=> volume = 36*11 π

=> Volume = 396π .cm^3

Answer:

multiply the first equation by -2, then add them

Step-by-step explanation:

7x+4y=-4         *-2 7x+4y=-4 *-2 = -14x-8y=8

5x+8y=28

-14x-8y=8                       x=-4, y=6

-9x=36

x=-4

7(-4)+4y=-4

-28+4y=-4

4y=24

y=6

Answer:

Height = 8 units

Step-by-step explanation:

Area of a triangle = [tex]36\frac{4}{5}[/tex] square units

                             = [tex]\frac{184}{5}[/tex] square units

Height of the triangle = [tex]9\frac{1}{5}[/tex] units

                                    = [tex]\frac{46}{5}[/tex] units

Formula to calculate the area of a triangle is,

Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

[tex]\frac{184}{5}= \frac{1}{2}\times (\frac{46}{5})\times (\text{Height})[/tex]

[tex]\frac{184}{5}= (\frac{46}{10})\times (\text{Height})[/tex]

Height = [tex]\frac{184}{5}\times \frac{10}{46}[/tex]

           = [tex]\frac{368}{46}[/tex]

           = 8 units

Therefore, height of the given triangle is 8 units.

Answer:

Ken class has a median of 84 while Judy class a median of 87

Step-by-step explanation:

Ken class has a median of 84 while Judy class a median of 87

Kens class has a mean score of 83, and Judy's class has a mean score of 86.43(rounded) so, judging by the mean, Judy's class is smarter. If we take a look at the median, (Ken: 84, and Judy: 87) then Judy's class is smarter. So, overall Judy's class is smarter than Ken's class.

Answer:

a) the midpoint is (1.5, 2.5)

b) the line is y = -(7/3)*x + 6.

Step-by-step explanation:

a)

Suppose we have two values, A and B, the mid-value between A and B is:

(A + B)/2

Now, if we have a segment with endpoints (a, b) and (c, d), the midpoint will be in the mid-value of the x-components and the mid-value of the y-components, this means that the midpoint is:

( (c + a)/2, (b + d)/2)

a) Then if the endpoints of the segment are (-2, 1) and (5, 4), the midpoint of this segment will be:

( (-2 + 5)/2, (1 + 4)/2) = (3/2, 5/2) = (1.5, 2,5)

The midpoint of the segment is (1.5, 2.5)

b)

Now we want to find the equation of a perpendicular line to our segment, that passes through the point (1.5, 2.5).

First, if we have a line:

y = a*x + b

A perpendicular line to this one will have a slope equal to -(1/a)

So the first thing we need to do is find the slope of the graphed segment.

We know that for a line that passes through the points (a, b) and (c, d) the slope is:

slope = (c - a)/(d - b)

Then the slope of the segment is:

slope = (4 - 1)/(5 - (-2)) = 3/7

Then the slope of the perpendicular line will be:

s = -(7/3)

Then the perpendicular line will be something like:

y = -(7/3)*x + d

Now we want this line to pass through the point (1.5, 2.5), then we can replace the values of this point in the above equation, and solve for d.

2.5 = -(7/3)*1.5 + d

2.5 + (7/3)*1.5 = d = 6

Then the line is:

y = -(7/3)*x + 6

The value of 'k' for the given system of equation that coincides  is 4

k=4

Given :

System of equations

[tex]2x+y=40 \\kx+2y=80[/tex]

The given equation is in the form of ax+by=c

When the two lines coincides then

[tex]\frac{a_1}{a_2} =\frac{b_1}{b_2} =\frac{c_1}{c_2}[/tex]

Lets make the coefficients proportional to each other and then solve for k

[tex]\frac{2}{k} =\frac{1}{2} =\frac{40}{80} \\\frac{2}{k} =\frac{1}{2} =\frac{1}{2} \\\\\frac{2}{k} =\frac{1}{2} \\4=k\\k=4[/tex]

The value of k from the given system of equation is 4

When the line coincides then the value of k is 4

Answer:

A general exponential equation is written as:

y = a*(b)^x

Where:

y represents the amount of something as a function of the variable x, where x is an independent variable.

a is the initial amount, this is, the value of y when x = 0.

b is the rate of growth, this defines how much changes the value of y as x increases.
