After watching some fish 55 feet below the surface of the water, a scuba diver went up 20 feet to explore a coral reef.
Use a number line to help you create an equation that
shows the location of the coral reef in relation to the
water's surface.

i'm a sophomore in connections, i'd recommend checking on jishka.com they have a large range of questions and answers from our school.

=

x=0.8898305 is the answer to that equation

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.
