Answer:
-21
Step-by-step explanation:
the y intercept is when x=0.
you can see that this is a linear equation where each increase in x results in an increase of 4 onto the y value.
so if when x=1, y=-17, subtract 4 to find what y equals when x is 0.
-17 -4=-21
good luck :)
I=k/d^2
4=k/d^2 and 1=k/64 so if we divide the first by the second we get:
4/1=(k/d^2)/(k/64)
4=(k/d^2)*(64/k)
4=64/d^2
d^2=64/4
d^2=16
d=4 meters
Here, the <em>standard deviation </em>is the best measure of the spread of a data set. The higher the standard deviation, the more spread out the distribution is. In this case, the distribution with the highest standard deviation (and therefore the greatest spread) is Distribution 3. Its low mean might be deceptive, but the value of a data set's mean has no effect on its spread.
6 times 12= 72. 72 times 7= 504. 504 square ft.
