Answer:
<h2>x = 21</h2>
Step-by-step explanation:
3x + 1 + 5x = 7 + 15 + 7x <em>combine like terms</em>
(3x + 5x) + 1 = (7 + 15) + 7x
8x + 1 = 22 + 7x <em>subtract 1 from both sides</em>
8x = 21 + 7x <em>subtract 7x from both sides</em>
x = 21
You have to make them have a common denominator which is 12 then to solve for z you subtract 9/12from10/12 and you get 1/12 z=1/12
Proportionately, the amount of the drug that the patient should be given is <u>2,993.71 mg</u>.
<h3>What is the proportion?</h3>
The proportion is the ratio of a variable to another.
Proportion defines the numerical relationships among variables.
Proportion shows how much a value is contained in the whole.
<h3>Data and Calculations:</h3>
2.20462 lb = 1 kg
165 lb = 74.8428 kg (165/2.20462)
1 kg = 40 mg of the drug
74.8428 kg = 2,993.71 mg (74.8428 kg x 40 mg)
Thus, the amount of the drug that the patient should be given is <u>2,993.71 mg</u>.

Step-by-step explanation:
Answer:
Probability=
Step-by-step explanation:
As it is given that
Probability of toy A is defective is =P(A) = 
Probability of toy b is defective if A is defective = P (B)=
WE have to find the P(A n B)
By the law of Probability
P(A n B) = P (A).P(B)
putting the values given to us
P(AnB)=
* 
Probability=
