A chemist is using 336 milliliters of a solution of acid and water. If 16.4% of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.

Amount of acid = 55.1 mm (Approx)

Step-by-step explanation:

Given:

Amount of solution = 336 mm

Percentage of acid = 16.4%

Find:

Amount of acid

Computation:

Amount of acid = Amount of solution x Percentage of acid

Amount of acid = 336 x 16.4%

Amount of acid = 55.1 mm (Approx)

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.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
