Derrick withdrew $17 from his account on Monday. The next day he deposited $12 in his account. What integer represents the total change in
his account over these two days?

The total change in his account is represented by the integer -5

Step-by-step explanation:

Operations With Integers

We need to perform addition and subtraction to complete the answer to this problem.

Derrick first withdrew $17 from his account. Since the money is coming out from the account, it's considered as negative. Thus this operation is recorded as -$17.

The next day he deposited $12, which is considered as positive. This operation is considered as $12 or +$12.

The net operation or total change in the account is: -$17 + $12.

Subtracting and simplifying: -$17 + $12 = -$5

The total change in his account is represented by the integer -5

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.
