Hello!
First you have to find the probability of a pulling a penny
To find this you put the amount of pennies over the amount of coins
There are 12 coins and 5 pennies
This is a 5/12 probability
Next you have to find the probability of then pulling out a quarter
Since you already took out a coin the total amount is now 11
The probability is 4/11
You multiply the two probabilities together to get the probability of them happening one after antoher
5/12 * 4/11 = 5/33
The answer is D)5/33
Hope this helps!
Answer:
Step-by-step explanation:
- Principal P = $2250
- Interest rate r = 2.4% = 0.024 PA compounded
- Compound number n = 1 (once per year)
- Time t = 6 years
<u>Future amount formula:</u>
<u>Substitute given values:</u>
- F = 2250(1 + 0.024)^6 = 2594.07
Answer:
# of cases: 11
Additional units: 2
Step-by-step explanation:
If each case can hold 8 units, and we want to find the total # number of cases, we have to divide the # of units (8) for one case by the total # units (90).
As you can see, after dividing by 8, we have a total of 11 cases and a remainder of 2 units. The remainder will be the # of additional units because we cannot have another case filled with 8 units.
Let's say that the price of each normal cookie is n.
The equation would then be 7(n - .75)=2.80.
Use distributive property, getting 7n - 5.25=2.80.
Add 5.25 to each side of the equation, getting 7n=8.05.
Divide 7 from both sides of the equation, getting n=1.15.
