Answer:
9. 1.24 mL
10. $5.93
Step-by-step explanation:
<u>Question 9:</u>
If the dosage of medicine is 0.01 mL per pound of weight of the patient, and the patient's weight is 124 pounds, we can set up an equation to solve for how much medicine the patient would need to take:
Dosage of medicine per pound of body weight x Total body weight = Total medicine required
OR
0.01 * w = m,
where w is total body weight and m is total medicine required.
To solve for the dosage the patient needs, just plug the numbers into the right places (124 for w and leave m as it is):
0.01 * 124 = m
1.24 = m
Therefore, a patient with a body weight of 124 pounds would need a 1.24 mL dosage.
<u>Question 10:</u>
To make the multiplication easier, we could rewrite 15% as 0.15 ( because 15% = 15/100):
0.15 * Total bill = Total tax payed for bill (Also can be written as )
OR
0.15*39.51 = Total tax
5.9265 = Total tax
5.93 = Total tax <-------- (rounded)

Answer: Our required probability is 0.515.
Step-by-step explanation:
Since we have given that
Probability that the respondents voted in favor of Scot Walker P(F) = 56%
Probability that the respondent voted in not favor of Scot Walker = 100-56 = P(F')=44%
Probability of those who did vote in favor had a college degree = 36% = P(C|F)
Probability of those who did vote against had a college degree = 44% = P(C|F')
So, we will use "Conditional Probability":
probability that he voted in favor of Scott Walker given that they had a college degree is given by
Hence, our required probability is 0.515.
