(SHOW WORK) Sofia conducted a scientific experiment. For a certain time, the temperature of a compound rose 1 3/4 degrees every 1 2/5 hours. What was the rate, in degrees per hour, that the temperature of the compound rose? Enter your answer as a whole number, proper fraction, or mixed number in simplest form.

0.8 degrees per hour

Step-by-step explanation:

1 2/5 divided by 1 3/4

7/5 / 7/4

keep, change, flip the fraction

7/5 x 4/7

=4/5= 0.8

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.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
