C + p + z = 15
z = 3
c = 3p

3p + p + 3 = 15
4p + 3 = 15
4p = 15 - 3
4p = 12
p = 12/4
p = 3.....he bought 3 bags of popcorn

c = 3p
c = 3(3)
c = 9 <== he bought 9 bags of chips

In the United States, 30% of people own a cat and 3% of people own a bird. What is the probability of someone owning both a cat
Alex777 [14]

Answer: 9/100

Step-by-step explanation:

Probability of people own a cat:

P(cat)=30/100=0.3

Probability of people own a bird:

P(bird)=3/100=0.03

Probability of both own a cat and a bird

P(cat and bird)=(30/100) × (3/100)

=90/1000=9/100=9%

1.<br> A patient is told to force fluids to 3 L/day. How many mls should she drink?
Damm [24]

The patient should drink 3000 milliliter per day

<em><u>Solution:</u></em>

Given that a patient is told to force fluids to 3 liter per day

To find: Amount the patient should drink in milliliter

Use the conversion factor,

1 liter = 1000 milliliter

Now we have to find the amount the patient she drink in milliliter

Amount patient drinks in liter = 3 liter per day

Therefore, convert 3 liter to milliliter

3 liter = 1000 x 3 milliliter = 3000 milliliter

Thus the patient should drink 3000 milliliter per day

Please help!!<br> If N is parallel to M, find the value of x and the value of z.
Butoxors [25]
Looking at the figure, we can see that both triangles are right triangles. Therefore, we can apply pythagorean theorems. A right triangle contains a hypotenuse, which is the longest side. In the figure, that would be sides with length 4 and 12. The equation for this is:

c = √(^2 + b^2) , where c is the hypotenuse and a and b are the other shorter sides

To determine z:
4 = √(z^2 + 3^2)
z = 2.65

To determine x:
12 = √(x^2 + 6^2)
x = 10.39
