A very large bag contains more coins than you are willing to count. Instead, you draw a random sample of coins from the bag and
Pie

Missing Details

Quarters  ≡ Dimes ≡  Nickels ≡  Pennies

23             ≡   29      ≡  17           ≡  38

Answer:

P(Q\ or\ P) = 0.5701

Step-by-step explanation:

Given

Quarters = 23

Dimes = 29

Nickels = 17

Pennies = 38

First, we calculate total number of coins

Total = 23 + 29 + 17 + 38

Total = 107

The probability of obtaining quarter (Q) of penny (P) is:

P(Q\ or\ P) = P(Quarters) + P(Pennies)

P(Q\ or\ P) = \frac{n(Quarters)}{Total} + \frac{n(Pennies)}{Total}

Take LCM

P(Q\ or\ P) = \frac{n(Quarters) + n(Pennies)}{Total}

P(Q\ or\ P) = \frac{23 + 38}{107}

P(Q\ or\ P) = \frac{61}{107}

P(Q\ or\ P) = 0.5701

A 100mL cup of very sweet tea consists of 90% water and 10% sugar. 20% of the tea is poured out. Then, 80mL of water are added.
nasty-shy [4]

Answer:

this probably wont help but

Step-by-step explanation:

<u><em>the tea in the large pitcher will be sweeter than the tea in the small pitcher. </em></u>

<u><em>There are many ways to draw diagrams of this situation, and many ways to reason about any given diagram. The key is to compare some like quantity between the two pitchers. In this example, we compare the amount of sugar in 2 cups of tea for each pitcher.</em></u>

<u><em></em></u>

<u><em>In the small pitcher (the top diagram), you can see in the diagram that for every 2 cups of tea, there is 1 teaspoon of sugar. But in the large pitcher (the bottom diagram), you can see that for every 2 cups of tea, there is more than 1 teaspoon of sugar.</em></u>

Which expression completes the statement to form a true equation? 2 + 4² = ???
Anastaziya [24]

Answer:

3^2 +9

Step-by-step explanation:

Since 2+4^2 is 16+2 which is 18, you need to find the expression equivalent to 18. 25 doesn't work so eliminate that right away. 9^2=81 so that isn't right either. 2^3+9=17 so that is incorrect. Lastly, 3^2+9=18 so that is the correct answer.

What is the value of x? 3/4x+5−1/2x=3
laiz [17]
3/4(x) + 5 - 1/2(x) = 3 
If x = -8 then, 
3/4(-8) + 5 - 1/2(-8) 
-6 + 5 - (-4) 
-6 + 9 
3 = 3 

Your answer would be that x = -8 

You're welcome.
