What is the slop of the graph of y=-3x?
Answers
Negative 3. Y=mx+b form, the "b" is your slope.
Answer:
Slope : -3
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
y-(-3*x)=0 <--------- rearranged linear equation
STEP 1:
Equation of a Straight Line
Solve y+3x = 0
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y+3x = 0 and calculate its properties
Graph of a Straight Line :
picture (attachment)
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 0/1 so this line "cuts" the y axis at y= 0.00000
y-intercept = 0/1 = 0.00000
Calculate the X-Intercept :
When y = 0 the value of x is 0/3 Our line therefore "cuts" the x axis at x= 0.00000
x-intercept = 0/3 = 0.00000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -0.000 and for x=2.000, the value of y is -6.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -6.000 - -0.000 = -6.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -6.000/2.000 = -3.000
Geometric figure: Straight Line
Slope = -6.000/2.000 = -3.000
x-intercept = 0/3 = 0.00000
y-intercept = 0/1 = 0.00000

There are 6 members of the student council and there are 10 chairs in their meeting room. If all 6 members
attend a meeting, how many different seating arrangements are possible?
Answers
The number of different seating arrangements is an illustration of permutation
There are 151200 different seating arrangements
How to determine the number of sitting arrangementsThe number of seats (n) is given as:
n = 10
The number of people (r) is given as:
r = 6
So, the number of seating arrangements is:
[tex]^nP_r = \frac{n!}{(n - r)!}[/tex]
This gives
[tex]^{10}P_6 = \frac{10!}{(10 - 6)!}[/tex]
Simplify
[tex]^{10}P_6 = \frac{10!}{4!}[/tex]
Evaluate the quotient
[tex]^{10}P_6 = 151200[/tex]
Hence, there are 151200 different seating arrangements

ProbabilityThe probability is found using the suggested resources. It will be ...
P(X<348) ≈ 0.6915
As a percentage, that is ...
0.6915 × 100% = 69.15%
The percentage of times shorter than 348 minutes is about 69.15%.

Find the equation of the line that passes through (2,-1) and is parallel to y = 4 − 2 x . Leave your answer in the form y = m x + c
Answers
Answer:
y = -2x + 3
Step-by-step explanation:
The slope intercept equation of a straight line is [tex]y=mx+b[/tex],
where m is the slope and b is the y-intercept.
Therefore, the slope of [tex]y=4-2x[/tex] is -2.
If a line is parallel to another line, they have the same slope.
Therefore, the slope (m) of the new line is also -2.
Using the point-slope form of a linear equation, where m = -2 and
[tex](x_1,y_1)[/tex] is a point on the line (2, -1):
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y+1=-2(x-2)[/tex]
[tex]\implies y=-2x+3[/tex]

tom training for a marathon he currently can run 12 miles in 3 hours. how long will it take tom to run 20 miles?
Answers
Answer:
5 hours
Step-by-step explanation:
because every hour she runs 4 miles so in 3 hours she will run 12 miles.
so 20 she would run 5 miles.
4 miles=1 hour
8 miles=2 hours
12 miles=3 hours
16 miles=4 hours
20 miles=5 hours.
Hope this helps have a great day:)
Answer:
Tom will take 5 hours
Step-by-step explanation:
Unit Rate
Tom runs 12 miles in 3 hours. We can calculate two different unit rates:
12 miles / 3 hours = 4 miles/hour
3 hours / 12 miles = 0.25 hours/mile
The first rate measures how many miles Tom runs per hour. The second rate measures how long it takes to Tom to run one mile.
We are asked to find the time needed for Tom to run 20 miles, thus the second rate will be useful:
0.25 hours/mile * 20 miles = 5 hours
To run 20 miles, Tom will take 5 hours

$2,800 - $560$2,240Weights of American adults are normally distributed with a mean of 180 pounds and a standard deviation of 8 pounds. What is the probability that a randomly selected individual will be between 185 and 190 pounds?
Answers
Answer:
There is 16.2% probability that a randomly selected individual will be between 185 and 190 pounds
Step-by-step explanation:
Z score
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ) / σ
where μ is the mean, x = raw score and σ is the standard deviation.
Given μ = 180, σ = 8.
For x = 185:
z = (185 - 180)/8 = 0.625
For x = 190:
z = (190 - 180)/8 = 1.25
P(185 < x < 190) = P(0.625 < z < 1.25) = P(z < 1.25) - P(z < 0.625) = 0.8944 - 0.7324 = 16.2%
There is 16.2% probability that a randomly selected individual will be between 185 and 190 pounds
