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

60% as a fraction =3/5
5/6-3/5

Determine whether y2=3x+1 is a function.
bazaltina [42]

Answer: it is not a function

Step-by-step explanation:

Given :

y^{2} = 3x + 1

The first thing is to make y the subject of the formula, that means we will take the square root of both sides

y = \sqrt{3x + 1}

since y =  \sqrt{3x + 1} , the the value of y could be positive or negative.

For example , \sqrt{4} = ± 2 , since -2 x -2 will also give + 4

For y =  \sqrt{3x + 1} to be a function , there must be a unique value for y for each value of x , but this is not the case as y could be positive or negative for a single value of x , so it is not a function.
