Find the distance between points p(8,2) and q(3,8) to the nearst tenth

7.8

Step-by-step explanation:

distance formula works like this

(difference in xs)²  = difference of 8 and 3 is 5² = 25

and

(difference in ys)² = difference of 2 and 8 is 6² = 36

add them = 61

square root of that = √61  = 7.8

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
