Answer:

A) 53

B) 53%

C) 37%

D) 63%

E) Yes.

Step-by-step explanation:

A) 53 people did not get headaches at all.

B) To solve for the percentage of participants that reported they did not get a migraine headache, you will need to divide out of the TOTAL number of people:

53/100= .53 --> Convert to percentage--> .53×100 = 53%.

C) To find this value, you will need to divide out of the amount of people that took MEDICINE and got a headache:

22/60≈0.367--> Convert to percentage --> 0.367×100≈37%

D) This percentage will be found out of who did NOT take the medicine:

25/40= 0.625 --> Convert to percentage --> 0.625×100≈63%

E) The medicine did help prevent migraine headaches because the percentage that got <u>migraines with the medicine is lower</u> than the percentage that got <u>migraines WITHOUT the medicine.</u>

5. One canned juice drink is 15% orange juice; another is 10% orange juice. How many liters of each should be mixed together in
hram777 [196]
X: liters of 15% orange juice
y: liters of 10% orange juice

x+y=5L

y=5L - x

x liters of 15% orange juice plus y liters of 10% orange juice makes 5 liters of 12% orange juice in equation form:

0.15x+0.10y = 0.12(5L)

0.15x+0.10(5L-x)=0.12(5L)

0.15x+0.5-0.10x=0.6

0.05x=0.1L

x=2L

so y = 3L

so you need 2 liters of 15% orange juice and 3 liters of 10% orange juice
