Answer: Yes

Step-by-step explanation:

It is a relation because each person will most likely have a different name and you can have plenty of the same outputs just as long as the input doesn't repeat at all.

Probability of someone either owning a dog or being male.<br>​
andrey2020 [161]

Answer:

c. 60.278%

Step-by-step explanation:

There is a 27.778% probability that someone owns a dog.

There is a 45% probability that someone is a male.

However, these two are not mutually exclusive.  12.5% both own a dog and are male.  If we simply add 27.778% and 45%, we'll be double counting the overlap.  To avoid this, we subtract 12.5%.

27.778% + 45% − 12.5% = 60.278%

solve using a system of equations. a pharmacist wants to mix two solutions to obtain 350 cc of a solution that has a 14% concent
Pavlova-9 [17]

Answer:

105 cc of 7% solution

245 cc of 17% solution

Step-by-step explanation:

If x = volume of 7% solution, and y = volume of 17% solution, then:

x + y = 350

0.07x + 0.17y = 0.14(350)

Solve with substitution:

0.07x + 0.17(350 − x) = 0.14(350)

0.07x + 59.5 − 0.17x = 49

10.5 = 0.10x

x = 105

y = 245
