The spinner's point has a 11.11% chance of landing on red.

A pie chart is a type of chart which displays data as a circular graph.

We comprehend that the pie's total value is always 100%. It is also assumed that a circle has a circumference of 360°. As a result, the sum of all pieces of data equals 360°. Based on these, there appear to be primarily two pie chart formulas:

Now, the stated data of the pie chart are-

When a circle is wholly rotated, the center forms a 360-degree angle.

A complete rotation at the central point of the circle yields 360 degrees.

The total color percentage is 100%.

Divide a red value by 3.6 because 360 ° / 100% = 3.6.

The spinner's pointer displays an overall percentage of red of 40%.

P = 40/3.6 (probability of each pointer landing on red).

P = 11.111.. = 11.11 (pointer landing on red) (approx.)

As an outcome, the pointer has a 11.11% chance of landing on the red.

The line's equation is y=3x-4.

What is Equation of line?

Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation where the slope of line is m and b is the y- intercept. The slope is defined as

m = (y-y1)/(x-x1)

Given:

For two lines to be perpendicular to each other, they must have slopes that are negative reciprocals of each other (i.e. the negative reciprocal of n is -1/n). The slope of the given line is –1/3 which means the slope of a line perpendicular to it would be 3.

From the given slope equation of the line

y=3x+b,

where b is the y-intercept. Since we know the line passes through the point (2,2).

(y-2)/(x-2) = 3

y-2 = 3*(x-2)

y=3x-6+2

y=3x-4

The value of b = -4

Therefore, the equation of the second line is y=3x-4.

Step-by-step explanation:

Theorem:  Interior angles of a quadrilateral sum to 360°.

Given angles:

Let x be the unknown angle.

⇒ 100° + 65° + 100° + x = 360°

⇒ 265° + x = 360°

⇒ 265° + x - 265° = 360° - 265°

⇒ x = 95°

Therefore, the fourth angle is 95°.

A kite is a quadrilateral that has one pair of congruent opposite angles.

Therefore, as two of the interior angles of the given quadrilateral are equal, the shape may be a kite.

Explanation:

Multiply the given values. This is because,

total mass = (number of paperclips)*(mass per paperclip)

So,

(5.0 x 10^−4)(6.85 x 10^4)

(5.0 * 6.85) x (10^−4 * 10^4)

34.25 x 10^(-4+4)

34.25 x 10^0

(3.425 x 10^1) x 10^0

3.425 x 10^(1+0)

3.425 x 10^1

3.4 x 10^1

We round the first value to 2 sig figs because it is the smaller sig fig count of 5.0 and 6.85; the 0 in 5.0 is significant.

Notice how I rewrote 34.25 into 3.425 x 10^1. I did this to get the number in the form a x 10^b, where [tex]0 \le a < 10[/tex], which fits scientific notation form.

The value 3.4 x 10^1 simplifies to 34. So an estimate of the total mass is about 34 mg. But we'll stick with scientific notation since your teacher instructed it.

The linear equation with a direct variation function always passes through the origin.

What are direct variation functions?

The direct variation function defines a linear function of the form y = kx, where y varies as a multiple of x and x 0. These always follow the origin test.

Calculation

Yes, the method will always work because the linear equations having direct variations are those equations which always pass through the origin.

For example: If we consider an equation y = 3x. Then, it will always pass through the origin as y changes with respect to some multiples of x.

Hence, the direct variation function always passes through the origin.

If Jenny's Bakery sells carrot muffins at 2 each and the electricity to run the oven is 120 per day and the cost of making one carrot muffin is 1.40, then the number of muffins needed to be sold each day to break even is equal to 200.

The number of muffins needed to be sold each to break even can be determined by forming a linear equation.

A linear equation, sometimes also referred to as a first-degree equation can be described as an equation that contains variables that have the maximum power of not more than one.

The linear equation for this problem will be,

Cost of electricity to run the oven + Cost of making x number of muffins = Sale price of x number of muffins

120 + 1.40 (x) = 2 (x)

Here x is equal to the number of muffins

Rearranging the equation,

120 = 2(x) - 1.40 (x)

120 = 0.6 (x)

120/0.6 = x

x = 200

Hence, 200 muffins are needed to be sold each day to break even.

The point slope form finds the equation of a straight line that passes through a given point and is inclined to the x-axis. Each point on a line must satisfy the line's equation. Two-variable linear equations symbolize lines. The point slope formula is utilized when we know the line's slope and a point. The next section explains the point slope form and how to calculate its formula.

The equation of a straight line that is inclined at a particular angle to the x-axis and passes at a given point may be found by using the point slope form. This form is used to get the equation of the line. An equation may be said to be the equation of a line if it can be shown to be fulfilled by every point along the line. This indicates that a line is represented by a linear equation that has two variables.

Answer:

1) the center is (3,4), radius is 3. 3)  ( x − 2 )^2 + ( y − 14 )^2 = 9, 5) the center is (12,5), the radius is 4

Step-by-step explanation:

For the graphs just look for the middle point, and thats essentially your center, and the radius is how many units the edge of the circle is to the center. So for 1 the center would be (3,4) and the radius 3. For problem 3 use the equation  ( x − a )^2 + ( y − b )^2 = r^2, where you substitute the radius for r, your x center coordinate as a, and your y coordinate as b. In problem 5, use 12 as your x value for the center coordinate, and 5 as your y value. Then just take the root of 16 to get your radius, and apply that to the other problem. Hope this helps :)

Answer:

a₁ = 15

Step-by-step explanation:

the sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

given S₁₄ = - 63 , then

[tex]\frac{14}{2}[/tex] [ 2a₁ + 13d ] = - 63

7(2a₁ + 13d) = - 63 ( divide both sides by 7 )

2a₁ + 13d = - 9 → (1)

the nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

given a₁₄ = - 24 , then

a₁ + 13d = - 24 → (2)

subtract (2) from (1) term by term to eliminate d

a₁ + 0 = - 9 - (- 24)

a₁ = - 9 + 24 = 15
