Answer:90
Step-by-step explanation:
Multiply by 10
Answer:
8.9 meters
Step-by-step explanation:
this seems like a problem where you can use the pythagorean theorem:
you know one of the two legs (6m) and the hypotenuse (9m), you must find the other leg
a^2 + 6^2 = 9^2
a^2 + 36 = 81
a^2 = 45
a = or · which simplifies to be 3 or approx. 8.9 meters
So, we need to do the distance she travelled (21 miles) divided by the rate at which she travelled (4 hours). Therefore, because 21 divided by 4 is 5.25, she biked at a speed of 5.25 mph (Miles per hour). So, if she bikes 5.25 miles every hour we can divide 42 by 5.25 to get the time it would take her to travel 42 miles. Now, 42 divided by 5.25 equals 8, so that means for Shelly to bike 42 miles at her average speed of 5.25 mph, it would take her 8 hours.
3) This is definitely a positive association, but the question is - is it linear?
Since a somewhat straight line can be drawn through the points, it is linear.

Answer: positive linear association </span>
4) Find the slope using the formula
m = 43 - 48/ 4 - 2 = -5/2 = -2.5
Negative association, but is it linear? Lets find out
Oh no! It seems that their is not a pattern in the association, so its nonlinear!
Answer: Negative nonlinear association5) <span>
m = 80 - 66/ 5 - 3
m = 14/2
m = 7
Positive! But is it linear??
Let us draw a graph this time.
I know my graph is messy, but can you see the nonlinear-ness? It doesnt form a straight line!
Answer: Positive nonlinear association </span><span>Hope this helped. :) </span>
