(1) the probability of that happening is .4444.. so on. the jar isnt 25% red balls because 25% of 36 is only 9 and he pulled out 16 red balls.
I dont know number two sorry.
Answer:
Five sixths of a yard is 30 inches
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
Cost per item is found by dividing the cost by the number of items. If the woman bought n items for $120, the cost of each item is $120/n. If the woman bought 24 more items, n+24, at the same price, then the cost per item is $120/(n+24). The problem statement tells us this last cost is $16 less than the first cost:
120/(n+24) = (120/n) -16
Multiplying by n(n+24) gives ...
120n = 120(n+24) -16(n)(n+24)
0 = 120·24 -16n^2 -16·24n . . . . . . subtract 120n and collect terms
n^2 +24n -180 = 0 . . . . . . . . . . . . . divide by -16 to make the numbers smaller
(n +30)(n -6) = 0 . . . . . . . . . . . . . . factor the quadratic
The solutions to this are the values of n that make the factors zero: n = -30, n = 6. The negative value of n has no meaning in this context, so n=6 is the solution to the equation.
The woman bought 6 items.
_____
Check
When the woman bought 6 items for $120, she paid $120/6 = $20 for each of them. If she bought 6+24 = 30 items for the same money, she would pay $120/30 = $4 for each item. That amount, $4, is $16 less than the $20 she paid for each item.
Mia tossed a penny,a nickel and a dime all possible outcomes of H is the answer C.
Step-by-step explanation:
- The two possible outcomes for penny,nickel and dime is H & T.
- H is for head T is for tail.
- Let A {HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}
- Tossing a fair coin will give the above result.
- S is the called the n number of outcomes that are available for a set.
- Total outcome of Sample space 8.
- The three diagram is like a game theory it exploits different outcome.
Pretty sure it’s C That one makes the most sense to me please let me know if you get it right
