<span>Since y=4, when x=-2, plug it into the formula above, and you have
y=kx
4=k(-2)
Solve for k, k=-2
</span><span>Now, y = -2x, so if x=30</span>y=-2*30=-60.
You find a percentage you would change it into a fraction 21/25 and then you would divide the numerator by the denominator 21÷25=.84 you then move the decimal point two digits to the right to express as 84%
Do you mean the width is five less than the LENGTH of the rectangle
To find the mean, add up all of the miles and divide by the number of years. 12100 + 15758 + 12200 + 11800 + 12750 = 64608. 64608/5 = 12921.9. The mean (the average) is 12,921.9 miles.
To find the median, put the numbers in order and find the middle number. The middle number is 12200. The median (middle number) is 12,200 miles
To find the mode, you would look for the number that is repeated the most. In this data set, no number repeats, so there is no mode. There is no mode for this data set.
The mean (average) would be the best measure of central tendency to predict how many miles Gina will drive in the sixth year.
I hope this helps! Can I have Brainliest, please? :)
