<h3>Option D) Seagull, crow | bat, mosquito</h3>
38 and 95 both divide into 1520 w/ a reminder of 8
There are 5 milliliters of compound A for every 7 milliliters of compound B.
So the ration between compound A and B will be:
A:B = 5:7
Total amount of drug = 684
Therefore, the amount of drug A needed will be:
Therefore, out of 684 milliliters 285 would be the compound A and the rest would be compound B
To find the mean, add all the numbers together and divide by the amount of numbers there is
89 + 92 + 97 + 81 + 96 = 455
455/5 = 91
91 is Andrew's mean score, and is your answer
hope this helps
