The theater has 7 rows of 8 chairs. for an upcoming show the theater needs to have 5 times more chairs. they are able to add 3 more chairs to each row and can add as many rows as they need. how many total rows would be required?

26 rows

Step-by-step explanation

Since each row as 8 chairs and they can add 3 chairs to each row,

the rows can now have 11 chairs in them.

they needed 5x as many chairs as 8x7. this equals 280 chairs (8x7=56--> 56x 5 = 280) 280 divided by 11 chairs per row is 25.48 which is 26 rows with some empty chairs left over, therefore your answer is 26 rows.

number 1 is 56 number 2 is 28

Step-by-step explanation:

it said it

x + 107

step-by-step explanation:

let's say that the number he had before the mistake was x. then, he will have 107 dollars more than this, so the answer is x + 107.

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.
