Answer:
B. y = -2/3x + 12
Step-by-step explanation:
Formula to find the slope when given two points on a line:
<u>y</u><u>2</u><u> </u><u>-</u><u> </u><u>y</u><u>1</u>
x2 - x1
Substitute the two given points (6, 8) (9, 6):
<u>6</u><u> </u><u>-</u><u> </u><u>8</u>
9 - 6
Slope = -2/3x
We found the slope! And the answer choices already gave us one y-intercept, which is 12. The last thing we do is we form an equation with the information we solved and that was given to us.
y = slope (x) + y-intercept
y = -2/3x + 12
The answer choice that matches this equation is B.
In conclusion, the equation that best estimates the line of best fit shown above is answer choice B.
Answer:
1/2 or 50%
Step-by-step explanation.
The coin has two sides you have a 50% chance on heads and a 50% chance on tail.
Answer:
$49
Step-by-step explanation:
$70 - 30% = $49
Answer:
y=7/6x
Step-by-step explanation:
When given an equation and asked to find the equation of a perpendicular line that intersects it, you know that the slope is the slope of the equation is the negative recipricoal of the given equation. i.e. y=2x+2 and y=-1/2x+2. The y-intercept does not matter.
I hope you understood and that this helps!
As given by the question
There are given that the dot plots that show the ages of students.
Now,
As obtained from the dot plot:

Now,
The mean of the given data is:

So,

Then,

And,
The mode of the given data is:
The mode is defined for the most frequently occurring value
So,

Hence, the value of the mean is 12.8 and the mode is 13.
