Question:
Jin Ya take the bus across town to school each morning last week he timed his trips and found that the time varies day today the time in minutes or listed below:
10 15 11 13 11
If you had to use one number to tell someone how long it took Jin Ya to get to school, what would you say?
Answer:
11 minutes or 12 minutes
Step-by-step explanation:
Given:
10 15 11 13 11
Required
Determine one number that summarizes the 5 numbers
First, one can use the mean to get the summary of the numbers.
The mean is calculated as:
[tex]Mean = \frac{Sum\ of\ observation}{Number\ of\ observation}[/tex]
[tex]Mean = \frac{10 + 15 + 11 + 13 + 11}{5}[/tex]
[tex]Mean = \frac{60}{5}[/tex]
[tex]Mean = 12[/tex]
Another number that summarizes the numbers is the mode of the distribution.
[tex]Mode = Highest\ Occurring\ Value[/tex]
So, in this case:
[tex]Mode = 11[/tex]
Hence, you can either use 11 minutes or 12 minutes.

Answer:
1. Second Choice
2. Positive
3. Line B
4. Line D
5. Horizontal
Step-by-step explanation:
First ScreenshotThe y-intercept is the value of b —
[tex]y = mx + b[/tex]
where m = slope and b = y-intercept.
Looking from the graph, the graph passes y-axis at (0,1) which is y-intercept.
Basically (0,a) is y-intercept.
Thus, our y-intercept is (0,1)
Second ScreenshotThe slope is positive. If the slope is negative, it would face opposite.
For zero slope, the graph will become a horizontal line.
An undefined slope is the vertical line graph.
Third ScreenshotLine B has zero slope. As said, the zero slope will turn the graph into a horizontal line.
Fourth ScreenshotLine D has an undefined slope. Read Third Screenshot.
As said, an undefined slope is the vertical line.
Fifth Screenshot[tex]y = - 3[/tex]
This is called Constant Function where the graph is a horizontal line. For a vertical line, it must be x = a (where a is constant)
FYI,
y = a — horizontal
x = a — vertical

An angle measures 158º more than the measure of its supplementary angle. What is the measure of each angle? _° and _°
Answer: 158 and 28
Step-by-step explanation:
Supplementary angles are angles that add to 180, so 180-158 = 28 degrees.

If 10x +5 = 100, is x greater than 10 or less than 10? Without solving the equation, explain how you
know.
Answer:
Step-by-step explanation:
X is less than 10 because you have the plus in the equation and so it as to be less than ten so that when you multiply it by 10 it equals less than 100. I don’t know if my explanation makes sense but I hope it helps.

What is the answer to:
x/-6 -8 ≤ -12
Answer:
x (is greater than or equal to) -24
Step-by-step explanation:
x/-6 - 8 (is greater than or equal to) -12
add 8 to both sides
x/-6 (is greater than or equal to) 4
multiply both sides by -6
x (is greater than or equal to) -24

[tex]\textsf{We are given an equation where x is on both sides of the equation.}[/tex]
[tex]\large\underline{\textsf{Solving;}}[/tex]
[tex]\textsf{Begin solving by adding x to both sides of the equation to cancel out -x on the right}[/tex]
[tex]\textsf{side of the equation. Afterwards, simplify the left side of the equation to evaluate}[/tex]
[tex]\textsf{x.}[/tex]
[tex]\large\underline{\textsf{Evaluating x;}}[/tex]
[tex]\tt -2 + x= -x + 2[/tex]
[tex]\textsf{Remove the -x on the right side by adding x to both sides of the equation.}[/tex]
[tex]\tt -2 + x +\boxed{\tt x} = -x + \boxed{\tt x}+ 2[/tex]
[tex]\tt -2 + 2x = 2[/tex]
[tex]\textsf{Now, we should simplify the left side of the equation as there's only a whole number}[/tex]
[tex]\textsf{on the right side of the equation.}[/tex]
[tex]\textsf{Remove the -2 on the left side of the equation by adding 2 to both sides of the equation.}[/tex]
[tex]\tt -2 + \boxed{\tt 2}+ 2x = 2 + \boxed{\tt 2}[/tex]
[tex]\tt 2x = 4[/tex]
[tex]\textsf{Lastly, divide both sides of the equation by 2 to find the value of x.}[/tex]
[tex]\tt \frac{2x}{2} = \frac{4}{2}[/tex]
[tex]\large\boxed{\tt x=2}[/tex]
Answer:
[tex] \sf \: x = 2[/tex]
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
The equation is,
→ -2 + x = -x + 2
Then the value of x will be,
→ -2 + x = -x + 2
→ x + x = 2 + 2
→ 2x = 4
→ x = 4 ÷ 2
→ [ x = 2 ]
Hence, the value of x is 2.

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 8 N acts on a certain object, the acceleration of
the object is 4 m's?. If the force is changed to 18 N, what will be the acceleration of the object?
Answer:
[tex]9\ m/s^2[/tex]
Step-by-step explanation:
For a moving object, the force acting on the object varies directly with the object's acceleration.
F ∝ a
or
[tex]\dfrac{F_1}{a_1}=\dfrac{F_1}{a_2}[/tex]
Put F₁ = 8 N, a₁ = 4 m/s², F₂ = 18 N and a₂ = ?
Put all the values,
[tex]\dfrac{8}{4}=\dfrac{18}{a_2}\\\\2=\dfrac{18}{a_2}\\\\a_2=9\ m/s^2[/tex]
So, the new acceleration is [tex]9\ m/s^2[/tex].
Help!! Find the indicated angle measure. Show your work.
Answer:
m∠NPM = 101
Step-by-step explanation:
Since LM is a straight line, Angle LPM and Angle NPM have to equal 180 degrees (they are supplementary), so we make the equation:
180-79=measure of angle NPM
m∠NPM = 101
Answer:
<NPM = 101°
Step-by-step explanation:
<NPM = 180° - <LPN ( because LPM is a straight line and it should measure 180°)
<NPM = 180° - 79°
<NPM = 101°

Two rules for creating a pattern are given below. Each rule begins with a number called the input ar creates a number called the output.
Answer:
20 Input
10 output
Step-by-step explanation:
Here, we want to select the input and output that works
From the diagram, the correct answer is 20 and 10
Let us look at how the rule is followed;
divides input by 2
20/2 = 10 which is the output
Subtract 10 to get output
20-10 = 10

A triangle with vertices D, E, and F are plotted on the coordinate plane at (0, 5). (2, 0), and (-4, 2), respectively. When constructed,
medians DG and EH intersect at the point with which coordinates? Round each coordinate to the nearest tenth if necessary.
A. (-0.7, 2.5)
B. (-1, 1)
C. (-0.7, 2.3)
D. (-2, 3.5)
Given:
Vertices of a triangle are D(0,5), E(2,0) and F(-4,2).
To find:
The intersection point of medians DG and EH.
Solution:
We know that, intersection point of all the medians of a triangle is called centroid.
The formula of centroid is
[tex]Centroid=\left(\dfrac{x_1+x_2+x_3}{3},\dfrac{y_1+y_2+y_3}{3}\right)[/tex]
Vertices of a triangle are D(0,5), E(2,0) and F(-4,2). So, the centroid of the triangle is
[tex]Centroid=\left(\dfrac{0+2+(-4)}{3},\dfrac{5+0+2}{3}\right)[/tex]
[tex]Centroid=\left(\dfrac{-2}{3},\dfrac{7}{3}\right)[/tex]
[tex]Centroid=\left(-0.666...,2.333\right)[/tex]
Round each coordinate to the nearest tenth.
[tex]Centroid=\left(-0.7,2.3\right)[/tex]
Therefore, the correct option is C.

Write an equation of the line that passes through (2,-1) and is parallel to the line y=-3x+8
Answer:
y = - 3x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 8 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, then
y = - 3x + c ← is the partial equation
To find c substitute (2, - 1) into the partial equation
- 1 = - 6 + c ⇒ c = - 1 + 6 = 5
y = - 3x + 5 ← equation of line
