PLZZZ HELP ME OUT THIS DUE RIGHT NOW AND I FREAKING OUT PLEASE HELP ME P. S YOU HAVE WRITE ANSWERS FOR ALL OF THEM Task 1 – Operations on the Number Line
(Variation of the above task)
A number line is shown below. The numbers 0 and 1are marked on the line, as are two other numbers a and b.

For each of the following expressions determine if the answer would be positive, negative, or zero. For each one PROVE HOW YOU KNOW.

1. a−1


Explanation:

2. a−2


Explanation:

3. b−1


Explanation:

4. -b−b


Explanation:

5. a−b

Explanation:

6. ab+1

Explanation:

7. b− a

Explanation:

8. a a-b x b


Explanation:

a then b each have a value work out whether its numbered or distributed on a number line -2 , -1 0 , 1, 2, 3, 4, 5 etc if a is -4 then if 1-a = 1--4 the answer is -5 then when the question ab +1 comes up if b = 3 then ab-1 will be written out again as -4 x 3 -1 = -12-1=-13 etc. etc.

ab+1 is different if a = -4 and b = 3 then ab+1 = -4 x 3 +1 = -12 +1 = -11

its count back for( minus then times) count back for( minus then subtract ) and count back for any subtract and forward for positive add minus

Hope that helps branliest please =)

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.
