Answer: Cost of each hot dog and bratwursts would be $1.1 and $1.35 each.
Step-by-step explanation:
Since we have given that
Cost of each dozen hot dogs be 'x'.
Cost of each dozen bratwursts be 'y'.
The first day they sold 8 dozen hot dogs and 13 dozen bratwursts for $316.20.
So, the equation would be
.The second day they sold 10 dozen hot dogs and 15 dozen bratwursts for a total of $375.00.
So, the equation would be
So, the equations becomes
So, by elimination method, we get that
Put the value of y in the eq(1), we get that
Hence, the cost of hot dogs would be 
And the cost of bratwursts would be 
Answer: 5 gallons
Step-by-step explanation:
There are 3 x's on the graph for 1/4, so 1/4 times 3=3/4
There are 2 x's on the graph for 3/8, so 3/8 times 2=3/4
There are 4 x's on the graph for 5/8, so 5/8 times 4=5/2
There is only 1 x for 1, so it will remain 1.
So if you add these up,
3/4+3/4+5/2+1
6/4+10/4+1
16/4+1
4+1
There is 5 gallons of sap produced that day.
Hope this helped!
Conditional probability is a measure of the probability of an event given that another event has occurred. If the event of interest is A and the event B is known or assumed to have occurred, "the conditional probability of A given B", or "the probability of A under the condition B", is usually written as P(A|B), or sometimes
.
The conditional probability of event A happening, given that event B has happened, written as P(A|B) is given by
In the question, we were told that there are three randomly selected coins which can be a nickel, a dime or a quarter.
The probability of selecting one coin is
Part A:
To find <span>the probability that all three coins are quarters if the first two envelopes Jeanne opens each contain a quarter, let the event that all three coins are quarters be A and the event that the first two envelopes Jeanne opens each contain a quarter be B.
P(A) means that the first envelope contains a quarter AND the second envelope contains a quarter AND the third envelope contains a quarter.
Thus
</span><span>P(B) means that the first envelope contains a quarter AND the
second envelope contains a quarter

Therefore,
Part B:
</span>To find the probability that all three coins are different if the first envelope Jeanne opens contains a dime<span>, let the event that all three coins are different be C and the event that the first envelope Jeanne opens contains a dime be D.

Answer:
0.5 A
Step-by-step explanation:
Hi,
I believe the question is incomplete. However, as per the information provided:
The simplest way to calculate the Current (unit is Amperage), is understanding the relationship between the three: Power, Voltage and Current.
<em>(Quick Tip: </em><em>W=AV</em><em>; where W -> Watts (Power), A -> Ampere (Current), V -> Volts (Voltage))</em>
Using the formula we calculate the Ampere:
W = A x V
60 = A x 120
60/120 = A (We divide the equation be 120)
0.5 = A (Simply reduce the fraction 60/120 = 1/2 = 0.5)
Tip:
I believe this would take the form of an exponential
equation:
A = Ao (1 + r)^t
where A is final population, Ao is initial population, r
is rate of growth and t is time
A / Ao = (1 + r)^t
log A / Ao = t log (1 + r)
t = (log A / Ao) / log (1 + r)
t = [log (1000 / 550)] / log (1.075)
t = 8.27 years
SO the answer is B) about 9 years
