Description:

According to the information in Figure 1, what is the maximum shark size for a wind speed of ~18 knots?


Transcript

00:00

Yeah Oh Table one below shows the recorder data from

00:10

each scavenging event In this study got whale species and

00:14

signs and wind direction Speed Really follow things Figure one

00:19

illustrates the relationship of wind speed Teo maximum shark size

00:24

The straight line and figure one is a linear regression

00:27

fit to the data points to illustrate a direct relationship

00:30

between wind speed and maximum shark sides Okay next up

00:35

according to the information and figure one What is the

00:39

maximum shark size for a wind speed of around eighteen

00:43

knots Okay Mac Shark size eighteen knots Well we made

00:48

the mistake of doing these drills on an empty stomach

00:50

So diverse it seemed that this question was dealing with

00:52

garlic knots Way were grossed out by the thought of

00:55

someone asking about wind speed and direction Garlic does that

00:59

to us but never mind Anyway we first should find

01:02

the point on the line given and figure one that

01:05

corresponds to a wind speed of about eighteen Not So

01:08

Where is that It's right about here We find it

01:11

by looking at the data point that falls halfway between

01:14

fifteen and twenty Those were the knot marks there on

01:17

the horizontal axis So like right around there Then we

01:21

check out the corresponding value of the vertical access over

01:23

here Why access Thinking they're alright Well out of the

01:26

answer choices and four point nine meters right there is

01:31

closest to this value So that's it So that's our

01:34

answer Be about four point nine And another way to

01:37

solve this one is to put the X's value of

01:39

eighteen in the equation given in the figure to solve

01:42

for why Maximum shark's eyes Right Well this will give

01:45

you a value that four point nine four four meters

01:47

thing All right Excuse us We're going to go get

01:50

some garlic pizza here now and not feed it to 00:01:52.19 --> [endTime] the sharks
