70 students out of the 6th grade went to an animal shelter for a field trip. This is 60% of the 6th grade. How many students are in the 6th grade?

116 students

Step-by-step explanation:

70 is 60% of a whole. In order to find the whole we must divide.

turn 60% to a decimal (move the decimal two spaces to the left: 0.6) then divide 70/0.6 and that equals 116.6, but obviously we can't split up a person so we have to round down to the nearest whole which is 116.

so, 70 is 60% of the whole 116.

to check your answer, you can do 116*0.6 which equals 70.

Hope this helps!

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.

f(x) = y

f(-3) = -5
