find the highest common factor of 9, 12 and 15
Hello there! :)
The highest common factor of 9, 12, and 15 is 3.
To find the HCF (also called the GCF) of two or more numbers, we list their factors:
9: 1, 3, 9
12: 1, 2, 3, 4, 6, 12
15: 1, 3, 5, 15
Can you see that 3 is their GCF?
Hope this helps!

HELP PLS! Suppose the year of car accidents per day in Wilmington NC has been recorded for the past year. The table below is a probability distribution table representing the data collected.
1) what is the probability that on a randomly selected day there were no accidents?
2) find the probability there will be at least 2 accidents
3) on any given day how many accidents should the Wilmington police expect to have.
According to the discrete distribution given:
1) There is a 0.18 = 18% probability that on a randomly selected day there were no accidents.
2) There is a 0.7 = 70% probability that there will be at least 2 accidents.
3) On any given day, the Wilmington police should expect to have 2.03 accidents.
The distribution is:
[tex]P(X = 0) = x[/tex]
[tex]P(X = 1) = 0.12[/tex]
[tex]P(X = 2) = 0.32[/tex]
[tex]P(X = 3) = 0.25[/tex]
[tex]P(X = 4) = 0.13[/tex]
Item 1:
The sum of the probabilities has to be 100% = 1, hence:
[tex]x + 0.12 + 0.32 + 0.25 + 0.13 = 1[/tex]
[tex]x + 0.82 = 1[/tex]
[tex]x = 0.18[/tex]
0.18 = 18% probability that on a randomly selected day there were no accidents.
Item 2:
This probability is:
[tex]P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4) = 0.32 + 0.25 + 0.13 = 0.7[/tex]
0.7 = 70% probability that there will be at least 2 accidents.
Item 3:
The expected value is the sum of each outcome multiplied by it's respective probability, hence:
[tex]E(X) = 0.18(0) + 0.12(1) + 0.32(2) + 0.25(3) + 0.13(4) = 2.03[/tex]
On any given day, the Wilmington police should expect to have 2.03 accidents.

Examine the table, which represents a linear function.
What is the rate of change of the function?
Input (x) Output (y)
-5 18
−3 23
−1 28
1 33
Answer:
I believe it should be 3 23
Answer:
2.5
Step-by-step explanation:
The rate of change can be found from the slope formula.
m = (y2 -y1)/(x2 -x1)
Using the first two lines of the table, we find ...
m = (23 -18)/(-3 -(-5)) = 5/2
The rate of change of the function is 5/2 = 2.5.

2. Explain the relationship between depression and heart disease.
Answer:
People with depression may have uncommonly sticky platelets, the tiny cells that cause blood to clot. In patients with heart disease, this can accelerate atherosclerosis (hardening of the arteries) and increase the chance of heart attack. Some studies show that treating depression make platelets less sticky again.
Answer:
People with depression may have uncommonly sticky platelets and tiny cells that cause blood to clot.
Patients with heart disease can accelerate atherosclerosis (hardening of the arteries) and increase the chance of heart attack.
For people with heart disease, depression can increase the risk of an adverse cardiac event such as a heart attack or blood clots.

need help urgently vvvvvvv
Step-by-step explanation:
you understand coordinates and how to find them in the chart, yes ?
because I can't draw here, I can only give you the points through which the line has to go.
one point is, of course, (2, -3).
to find another good point we use the slope 3/4.
the slope is the ratio of y change/x change when going from one point to another.
so, we find another point with integer coordinates by e.g subtracting the slope units from the point (addition would also work) :
the other point on the line would be
(2 - 4, -3 - 3) = (-2, -6)
and then you draw a line that goes through both points.

(5x-3=3x+29 )what is the value of X?
Answer: x=16
Step-by-step explanation:
Move the variable to the left-hand side and change its sign
5 x - 3- 3 x =29
Move the constant to the right-hand side and change its sign
5 x - 3 x = 29 + 3
Collect like terms
2 x = 29+ 3
Add the numbers
2x= 32
Divide both sides by 2
and you get x=16
Step-by-step explanation:
5x - 3 = 3x + 29
5x - 3x = 29 + 3
2x = 32
x = 32/2 = 16
x = 16 ans
therefore, value of x is 16.

6y−4x=20−4y+3x=−12
(4, 6)
(−4, 6)
(−4, −6)
Answer: A. (4,6)
Step-by-step explanation: 2(6y−4x = 20) 3(−4y+3x = −12) −8x+12y = 40 9x−12y = −36 -8x+9x +12y-12y 40-36 x=4 6y−4x = 20 6y−(4)(4) = 20 6y−16+16 = 20+16 6y/6 = 36/6 y = 6 x = 4, and y = 6.
The solution for the given system of equations is (4, 6). Therefore, option A is correct answer.
The given system of equations are 6y-4x=20 and -4y+3x=-12.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Here,
6y-4x=20 ----------(I) and -4y+3x=-12 ----------(II)
Multiply equation (I) by 3, we get
-12x+18y=60 ----------(III)
Multiply equation (II) by 4, we get
12x-16y=-48 ----------(IV)
Add equation (III) and (IV), that is
-12x+18y+(12x-16y)=60-48
⇒ 2y=12
⇒ y=6
So, 6y-4x=20
⇒ 36-4x=20
⇒ -4x=-16
⇒ x=4
The solution for the given system of equations is (4, 6). Therefore, option A is correct answer.
