True or false? The most common system of measurement for medication is the metric system.

Answers

Answer:

true

Step-by-step explanation:

The metric system is used for most scientific and medical measurements and all pharmaceutical companies now use the metric system for labeling medications.

Final answer:

The most common system of measurement for medication is indeed the metric system, which is utilized globally for its precision and universality. Its units cater to fundamental attributes in medicine dosages, such as volume, length and weight.

Explanation:

True, the most common system of measurement for medication is the metric system. This system is utilized globally and, in the healthcare field, it's critical for measuring and administering medications due to its precision and universality. The metric system's units of meters, liters, and grams cater to volume, length and weight - all fundamental attributes in medication dosages. If we take an example, a physician may prescribe 500 milligrams (mg) of a particular drug, where the milligram is a common metric unit used to denote mass.

Help to answer 2 & 3 Pablo and Jasmine had just started studying systems of linear equations in algebra. They looked at Pedro's drawing and said, "We could write that as a system of equations." Let t be the price of each taco and d be the price of each drink. - Write an equation that represents the cost of Pablo's order. (6T + 2D = 9) - Write an equation that represents the cost of Jasmine's order. (4T + 2D = 7) 2. What operations with the equations from part (1) match your way of using Pedro's sketch to find the prices t and d? 3. Why do the operations make sense?

Answers

Answer:

Step-by-step explanation:

The equation for Pablo's order is given as 6T+2D=9 or 6T+2D-9=0

While the equation for Jasmine's order is given as 4T+2D=7 or 4T+2D-7=0

Subtracting Jasmine's equation from Pablo's

6T+2D-9-(4T+2D-7)=0

This gives us

6T+2D-9-4T-2D+7=0

The reduces to

2T-2=0

Dividing all through by 2 gives

T-1=0

Therefore

T=1

Substituting the value for T into any of the equations of either Pablo and Jasmine

Using Pablo's

6T+2D=9

6(1)+2D=9

2D=9-6

2D=3

There D= 3/2

there is a bag filled with 3 blue and 4 red marbles. A marble is taken at random from the bag, the colour is noted and then it is not replaced. another marble is taken at random. what is the probability of getting 2 reds ?

Answers

You can just use some sort of counting principle
The first time you draw a read marble, your odds of getting 1 were 4/7
You are not replacing the marble. Your choice now is 3/6

P(2 reds) = (4/7) * (3/7) = 12/49  <<<<< Answer
the probability is:
(1)/(49)
1/49
