To solve this problem, all we need is the conversion factor.

We know that there are:

1 liter = 202.884 teaspoons

 

Therefore the mass of Phenobarbital is:

mass = (2 grams / 1 Liter) * (1 teaspoon) * (1 Liter / 202.884 teaspoons)

<span>mass = 0.00986 g = 9.86 x 10^-3 g = 9.86 mg</span>

Answer:

9.86 milligrams

Step-by-step explanation:

It is given that 1 liter f elixir contains 2 grams of phenobarbital elixir.

Since 202.884 teaspoons = 1 liter

so 1 teaspoon of elixir =  \frac{1}{202.884} liter

∵ 1 liter of elixir contains phenobarbital = 2 gms.

∴  \frac{1}{202.884} liter of elixir contains phenobarbital =  \frac{2*1}{202.884} = 0.009858 grams

or 0.009858 × 10³ milligrams

 = 9.86 milligrams.

Therefore, 9.86 milligrams of phenobarbital will be required.

Maria will spin the arrow on the spinner 2 times. What is the probability that the arrow will stop on the same letter twice? 19
gavmur [86]
Suppose the spinner lands on <em>a</em>.  There's a 1/3 chance that it'll land on <em>a</em> the second time.
Suppose the spinner lands on <em>b</em>.  There's a 1/3 chance that it'll land on <em>b</em> the second time.
Suppose the spinner lands on <em>c</em>.  There's a 1/3 chance that it'll land on <em>c</em> the second time.

We've covered all possibilities for the first spin, and they're all equal, so their average is 1/3.

The probability that it'll land on the same letter twice is 33.3%.

HURRY!!! I WILL GIVE BRAINLIEST FOR CORRECT ANSWER
Sergeeva-Olga [200]

Answer:

A function is a relation in which each element of the domain, or x-value, is mapped to one element of the range, or y-value.

The question we are asked is if cost is a function of the activity type.  This means that cost would be the range and activity type would be the domain.

If this is a function, then each activity type would have only one cost.  However, on different days of the week each activity type has different prices; this means there is more than one cost for each activity type, and it is not a function.
