Answer:
-6
(I don’t understand what you mean by on & 5 but..)
Step-by-step explanation:
The two negatives (the -(- ) cancel each other out and make a postive, so
-18 + 12 = -6
21/5.2
because in order to get mean you have to add all the numbers up and divide by the amount you added so 20+28+26+26+30+24+25+26+28+27= 210 divide by 10= 21
in order to get mad you take all the numbers and subtract them from the mean (what ever you get make sure the number is positive) so 21-20=1 28-21=7 and so on then add up the numbers and divide again to get 52 divide that by 10 and you get 5.2
because it is means to mad ratio the answer is 21/5.2
Answer:
Alright, here is the formula.
m = (y2 -- y1) / (x2 -- x1)
So, now we have to take the points and replace them with the variables.
m = (1 - 2) / (-2 - 4)
Great! So now, we have to solve.
1 - 2 = -1
-2 - 4 = -6
So now, it would be:
-1/6
That is the slope! Hope this helps! :)
Andre and his dad have been fishing for 2 hours. In that time, they have caught 9 blue gills and 1 yellow perch. How many total fish are there?
There are 10 total fish. We are looking at how many fish there are, so we need to add 9 + 1 to get our answer of 10 fish.
The next time Andre gets a bite, what kind of fish do you think it would be?
My prediction is that it will be a blue gill.
How do you know your prediction is more likely to happen?
9 out of 10 times, they have caught a blue gill. This is more probable than 1 out of 10.
Can you make any other predictions?
I would say that Andre will catch less yellow perches than blue gills. This is because the probability of catching a blue gill is greater than catching a yellow perch. I would also say that Andre will catch 5 fish per hour, since he caught 10 fish in 2 hours.
