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

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

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

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

$P(Q\ or\ P) = 0.5701$

Anita took 1/6 of a cake and Barry took 60% of what remained. What fraction of original cake is left. Explain full method.

Sedaia [141]

The cake = 1
1-1/6=5/6
60% as a fraction =3/5
5/6-3/5
25/30-18/30
7/30
There are 7/30 of the original cake left.

Hope this helps :)

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.
