Fittoniya [83]

Answer:

2000

Step-by-step explanation:

A(m) = 100 + 0.20m

Let a and b be the events of the fda approving and rejecting a new drug to treat hypertension, respectively. The events a and b
Law Incorporation [45]

The correct option is (d) Mutually exclusive events.

Let a and b be the events of the fda approving and rejecting a new drug to treat hypertension, respectively. The events a and b are mutually exclusive events.

Two events are mutually exclusive or disjoint in logic and probability theory if they cannot both occur at the same time. The results of a single coin toss, which can result in either heads or tails but not both, provide a clear illustration.

A statistical term used to describe events that cannot occur concurrently is "mutually exclusive." It is frequently used to refer to circumstances in which the occurrence of one event takes precedence over the other. For instance, it is impossible for war and peace to exist together. They are therefore opposed to one another.

insulin comes in 10 cubic centimeter(cc) vials labeled in the number of units of insulin per cubic centimeter of fluid. A vial m
Sergio [31]

Answer:

<em>8.25 cc fluid should be drawn into the syringe from the U40 vial.</em>

Step-by-step explanation:

The amount of a U40 vial insulin fluid is 10 cc.

A vial marked U40 has 40 units of insulin per cubic centimeter of fluid.

Suppose, if a patient needs 33 units of insulin, then x cc fluid should be drawn.

So, <u>according to the ratio of "cubic centimeter" to "the units of insulin"</u>, the equation will be.........

\frac{x}{33}=\frac{10}{40}\\ \\40x=330\\ \\ x=\frac{330}{40}=8.25

So, 8.25 cc fluid should be drawn into the syringe from the U40 vial.
