At sms, 25% of the teachers teach math. if there are 50 math teachers, how many teachers are there all together at sms?

200

Step-by-step explanation:

25 percent is known to be 1/4 of a number, so if 50 teachers represent 1/4 of all the teachers, that means that in order to get a full number, we must multiple 50 by 4 in order to get all 100% of the teachers.

By doing 50x4, we can conclude that 200 teachers teach at the school (aka 100% of all teachers)

200 teachers

Step-by-step explanation:

find the total number of teachers at SMS

25% are math teachers which = 50 math teachers

50 / 0.25 = 200

OR we can look  at it as 25% is one quarter or 1/4.

what is 50 a quarter or 1/4 of?

50 x 4 = 200

answer: ask

step-by-step explanation:

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.
