5 5/8= 5.625
1 1/4= 1.25
Arectalgle is Area= (length)(width) so fill in what you know.
5.625= (L)(1.25)
Divide both sides by 1.25
4.5=L
So 4 1/2 cm is the length
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.
First, find the mean. You'll need it to compute the variance.
The variance of the sample is then computed with the formula
The standard deviation is the square root of the variance, so
Answer:
2/3
Step-by-step explanation:
The slope is 2/3 because when using the rise over run formula
your rise would be 2 and the run would be 3
