Final answer:

To order the holes from least to greatest typical number of strokes per player based on the dot plots, count the number of dots for each hole and arrange the holes in increasing order.

Explanation:

To order the holes from least to greatest typical number of strokes per player, we need to look at the dot plots and determine the number of players represented by each dot. We can then count the number of dots for each hole and arrange the holes in increasing order based on the number of players. The hole with the least number of strokes per player would have the fewest dots, while the hole with the greatest number of strokes per player would have the most dots.

Let's say the dot plots show the following:

Based on the number of dots per hole, the order from least to greatest typical number of strokes per player would be:

Step-by-step explanation:

The following are some transformations for a function f(x):

1) If [tex]a(fx)[/tex] and [tex]|a|>1[/tex], then this function is stretched vertically by a factor of "a".

2) If [tex]a(fx)[/tex] and [tex]0<|a|<1[/tex], then this function is compressed vertically by a factor of "a".

Therefore, given the function [tex]f(x) = 3|x|[/tex], we can observe that the factor "a" is:

[tex]a=3[/tex]

Then:

[tex]a>1[/tex]

This means that  then this function is stretched vertically by a factor of 3.

Therefore, the scaling factor is 3.

Step-by-step explanation:

[tex]2x^2-5x+1=3[/tex]

To solve for x, we make right hand side 0

Subtract 3 from both sides

Given equation becomes

[tex]2x^2-5x-2=0[/tex]

We apply quadratic formula to solve for x

[tex]x=\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]

a=2, b=-5, c=-2

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

[tex]x=\frac{5+-\sqrt{41}}{4}[/tex]

[tex]x=\frac{5+\sqrt{41}}{4}[/tex] and [tex]x=\frac{5-\sqrt{41}}{4}[/tex]

Answer:

t = w/(11+r)

Step-by-step explanation:

To solve for t, we need to divide anything that t is multiplied to to get it on the other side of the equal sign.

w = t(11+r)

w/(11+r) = t

Answer:

t = w/(r + 11)

Step-by-step explanation:

Solve for t:

w = t (r + 11)

w = (r + 11) t is equivalent to (r + 11) t = w:

t (r + 11) = w

Divide both sides by r + 11:

Answer: t = w/(r + 11)

Answer:

R = 134

Step-by-step explanation:

This is a 5 sided figure.  The interior angles add to  (n – 2)180  where n is the number of sides

(5-2) * 180 = 540

Add up all the angles and set it equal to 540

R+ 78+109+113+106 = 540

Combine like terms

R + 406 = 540

Subtract 406 from each side

R +406-406 = 540-406

R = 134

b.2) The measure of each interior angle of hexagon is 120°

b.3) The measure of each interior angle of decagon is 144°

b.4) The measure of each interior angle of dodecagon is 150°

Part 2) The central angle and the interior angle are supplementary angles

Part 3) As the number of sides increases, the central angle decreases and the interior angle increases.

Step-by-step explanation:

Part 1. For each polygon, include the following information in the paragraph box below:

a) What was the central angle you used to locate the vertices? Show your calculation.

we know that

To find the central angle divide 360 degrees by the number of sides of the polygon

case a.1) Pentagon

The pentagon has 5 sides

so

The central angle is equal to

360°/5=72°

case a.2) Hexagon

The pentagon has 6 sides

so

The central angle is equal to

360°/6=60°

case a.3) Decagon

The pentagon has 10 sides

so

The central angle is equal to

360°/10=36°

case a.4) Dodecagon

The pentagon has 12 sides

so

The central angle is equal to

360°/12=30°

b) What is the measure of each interior angle of the polygon? Show your calculation

we know that

The sum of the interior angle of the polygon is equal to

S=(n-2)*180°

where

n is the number of sides

To find each the measure of each interior angle, divide the sum of the interior angles by the number of sides

case b.1) Pentagon

The pentagon has 5 sides

so

S=(n-2)*180°

S=(5-2)*180°=540°

Divide by the number of sides

The measure of each interior angle is equal to

540°/5=108°

case b.2) Hexagon

The hexagon has 6 sides

so

S=(n-2)*180°

S=(6-2)*180°=720°

Divide by the number of sides

The measure of each interior angle is equal to

720°/6=120°

case b.3) Decagon

The hexagon has 10 sides

so

S=(n-2)*180°

S=(10-2)*180°=1,440°

Divide by the number of sides

The measure of each interior angle is equal to

1,440°/10=144°

case b.4) Dodecagon

The hexagon has 12 sides

so

S=(n-2)*180°

S=(12-2)*180°=1,800°

Divide by the number of sides

The measure of each interior angle is equal to

1,800°/12=150°

Part 2. What is the relationship between the central angle and the interior angle?

we know that

The sum of the central angle plus the interior angle is equal to 180 degrees

therefore

The central angle and the interior angle are supplementary angles

Verify

Pentagon

72°+108°=180°

Hexagon

60°+120°=180°

Decagon

36°+144°=180°

Dodecagon

30°+150°=180°  

Part 3. As the number of sides increases, how do the angles change?

we know that

As the number of sides increases, the central angle decreases and the interior angle increases.

The option that's not true is:

C) p(4) = -4

Because if you look at that graph, you can tell, p(4) = 4 not -4.

The domain of the function p(x) = [x] is not all real numbers; it excludes integer values of x where the function is discontinuous. Statement D is not true.

The function p(x) = [x], where [x] represents the greatest integer less than or equal to x (the floor function). Let's evaluate each statement:

A) p(0) = [0] = 0. This is true.

B) p(-4) = [-4] = -4. This is true.

C) p(4) = [4] = 4. This is true.

D) The domain of p(x) is all real numbers. This statement is not true. The domain of p(x) is actually all real numbers except the points where x is an integer. At those points, there are discontinuities, and the function is undefined because the floor function jumps from one integer value to the next.

So, the statement that is not true is D) The domain of p(x) is all real numbers. The correct statement is that the domain of p(x) is all real numbers except at integer values of x.

And in Grade 8 is: 20/28 = 0.71.

Then, students of Grade 7 are more likely to be members of the science club.

Answer:

Step-by-step explanation: 26+2c=312

Now we solve for c.

Subtract 26 on both sides giving 2c=286

So c=143

This is the equation in numbers translated (n is a number)

26 + 2n = 312

We have to find what the number (n) is. This means we must isolate n. To do this you must subtract 26 to both sides

26 - 26 + 2n = 312 - 26

0 + 2n = 286

2n = 286

To further isolate n you must divide 2 to both sides

2n/2 =286/2

n = 143

Check:

26 + 143*2 = 312

26 + 286 = 312

312 = 312

The number is 143

Step-by-step explanation:

For there to be a correlation it  needs to either be in  a line or have equal stuff on both sides

Answer:

Option c is right

Step-by-step explanation:

Given is a scatter plot with points scattered.

We have to find from the shape the correlation coefficient

The points on the scatter plot do not support a linear correlation between the two variables.

There does not seem to be a line of fit which has minimum deviations from the line.

Hence there is no correlation is the correct answer.

From the given graph, we can say that option c is right.

Answer:

g(x) = (x + 3)^2 + 5(x + 3) - 1

Step-by-step explanation:

Please use " ^ " to denote exponentiation:  f(x) = x^2 + 5x - 1.

Shifting the graph of this function 3 units left results in

g(x) = (x + 3)^2 + 5(x + 3) - 1

To solve the equation, we can use algebraic techniques to find the value of 'x'.

To solve the equation, we can let the number be represented by 'x'. The equation can then be written as: (1/5)x + 5x = 7x - 18. Simplifying this equation gives us: (1/5)x + 5x - 7x = -18. Combining like terms, we get: (6/5)x = -18. Dividing both sides by 6/5 gives us the value of 'x'.

Follow below steps:

The question involves solving a linear equation to find an unknown number. To solve "one fifth of a number plus five times that number is equal to seven times the number less 18", the first step is to let "x" represent the unknown number and then create an equation based on the given information.

We start by translating the words into an equation:

One fifth of a number can be written as "(1/5)x".

Five times that number is written as "5x".

Seven times the number less 18 is written as "7x - 18".

So our equation becomes "(1/5)x + 5x = 7x - 18". Simplifying, we get "(6/5)x = 7x - 18".

Combining like terms yields "(1/5)x = -18", and we solve for x to find the value of the unknown number: "x = -90".

Through this process, the student can identify the value of the number in question.

Check the picture below.

By using a right triangle rectangle, we will see that the distance is equal to 3 miles.

You can think of the distance as the hypotenuse of a right triangle with legs that measure 1.8 miles and 2.4 miles.

Then, using the Pythagorean theorem we can write:

H^2 = (1.8 mi)^2 + (2.4 mi)^2

H = √((1.8 mi)^2 + (2.4 mi)^2) = 3mi

So the distance between Callie's house and the grocery store is 3 miles.

Step-by-step explanation:

1. Need to know

Slope and y-intercept.

You use these numbers to calculate one other point. Then you draw a straight line between the y-intercept and the other point to get the graph.

2. y-Intercept = 0

The form of the equation is y = mx + b, where b is the y-intercept.

If the intercept is zero, b = 0, and the equation has the form

y = mx

The graph is a straight line passing through the origin.

Answer:

x = 4.

Step-by-step explanation:

log(x) + log(x+5) = log(6x +12)

log x(x +5) = log(6x + 12)

Therefore x(x + 5)= 6x +12

x^2 + 5x - 6x - 12 = 0

x^2 - x - 12 = 0

(x - 4)(x + 3) = 0

x = -3, 4.

What is an Equation ?

An equation is a mathematical statement between two algebraic expressions equated by an equal sign.

A logarithm equation is given in the question.

log(x)+ log(x+5) = log(6x +12)

The equation of Logarithm says

log (x .y) = log x + log y

log(x)+ log(x+5) can be written as log (x(x+5))

log (x(x+5)) = log(6x +12)

We can relate this as

(x(x+5)) = 6x +12

x² + 5x = 6x +12

x² -x -12= 0

x² -4x +3x -12 = 0
