There are a total of 50 Questions worth 130 points on Chenille's history exam. Some questions are worth five points
each and the other questions are worth two points each. Which of the following systems of equations could be used to
determineſ, the number of five point questions and the number of two point question?

A.
f + t = 130
5f + 2t = 50
B.
f + t = 50
2f + 5t = 130

C.
f + t = 130
2 +5 = 50

D.
f + t = 50
5f + 2t = 130

answer: can you show the options ?

step-by-step explanation:

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
