In tryouts for the olympics a speed skater had times of 44,64,43,45,42,79 and 4,228 seconds find the average time add numbers

Step-by-step explanation:

Given

Time: 44.64,43.45,42.79 and 42.28

Required

Determine the average time

Average or mean is calculated as thus;

Where

= sum of observation

n = number of observation = 4

Hence, the average time is 43.29

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

they disappear if your absent from to long. i found out that the hard way.

step-by-step explanation:

brainliest lol i just need one more brainliest.
