After a late night of studying, Ebony decides to grab a latte before class so she can stay awake through her morning lecture. She has only a one-dollar bill, a five-dollar bill, and a ten-dollar bill in her wallet. She pulls one out and looks at it, but then she puts it back. Distracted by a flyer for a new campus organization, she randomly hands a bill from her wallet to the clerk. Construct a sample space, and find the probability that (a)Both bills have the same value. (b)The second bill is smaller than the first bill. (c)The value of each of the two bills is even. (d)The value of exactly two of the bills is odd. (e)The sum of the values of both bills is less than . Write your answers in exact, simplified form.
Answer:
[tex]P(Same\ Bill) = \frac{1}{3}[/tex]
[tex]P(Second<First\ Bill) = \frac{1}{3}[/tex]
[tex]P(Both\ Even) = \frac{1}{9}[/tex]
[tex]Pr(One\ Odd) = \frac{4}{9}[/tex]
[tex]P(Sum < 10) = \frac{1}{3}[/tex]
Step-by-step explanation:
Given
[tex]Bills: \$1, \$5, \$10[/tex]
[tex]Selection = 2\ bills[/tex]
The sample space is as follows:
This implies that we construct possible outcome that Ebony selects a bill, returns the bill and then select another.
This means that there are possibilities that the same bill is selected twice.
So, the sample space is as follows:
[tex]S = \{(1,1), (1,5), (1,10), (5,1), (5,5), (5,10), (10,1), (10,5), (10,10)\}[/tex]
[tex]n(S) = 9[/tex]
Solving (a): [tex]P(Same\ Bill)[/tex]
This means that the first and second bill selected are the same.
The outcome of this are:
[tex]Same = \{(1,1),(5,5),(10,10)\}[/tex]
[tex]n(Same\ Bill) = 3[/tex]
The probability is:
[tex]P(Same\ Bill) = \frac{n(Same\ Bill)}{n(S)}[/tex]
[tex]P(Same\ Bill) = \frac{3}{9}[/tex]
[tex]P(Same\ Bill) = \frac{1}{3}[/tex]
Solving (a): [tex]P(Second < First\ Bill)[/tex]
This means that the second bill selected is less than the first.
The outcome of this are:
[tex]Second < First = \{(1,5), (1,10), (5,10)\}[/tex]
[tex]n(Second < First) = 3[/tex]
The probability is:
[tex]P(Second<First\ Bill) = \frac{n(Second<First\ Bill)}{n(S)}[/tex]
[tex]P(Second<First\ Bill) = \frac{3}{9}[/tex]
[tex]P(Second<First\ Bill) = \frac{1}{3}[/tex]
Solving (c): [tex]P(Both\ Even)[/tex]
This means that the first and the second bill are even
The outcome of this are:
[tex]Both\ Even = \{(10,10)\}[/tex]
[tex]n(Both\ Even) = 1[/tex]
The probability is:
[tex]P(Both\ Even) = \frac{n(Both\ Even)}{n(S)}[/tex]
[tex]P(Both\ Even) = \frac{1}{9}[/tex]
Solving (e): [tex]P(Sum < 10)[/tex]
This question has missing details.
The correct question is to determine the probability that, the sum of both bills is less than 10
The outcome of this are:
[tex]One\ Odd = \{(1,10), (5,10), (10,1), (10,5)\}[/tex]
[tex]n(One\ Odd) = 4[/tex]
The probability is:
[tex]Pr(One\ Odd) = \frac{n(One\ Odd)}{n(S)}[/tex]
[tex]Pr(One\ Odd) = \frac{4}{9}[/tex]
Solving (d): [tex]P(One\ Odd)[/tex]
This question has missing details.
The correct question is to determine the probability that, exactly one of the bills is 0dd
The outcome of this are:
[tex]Sum < 10 = \{(1,1), (1,5), (5,1)\}[/tex]
[tex]n(Sum < 10) = 3[/tex]
The probability is:
[tex]P(Sum < 10) = \frac{n(Sum < 10)}{n(S)}[/tex]
[tex]P(Sum < 10) = \frac{3}{9}[/tex]
[tex]P(Sum < 10) = \frac{1}{3}[/tex]

Jay places $3200 in an investment account earning 4.1% interest compounded weekly. How much money would he have in the account after 5 years, if he made no deposits or withdrawals during that time?
Answer:
A = $3,926.71
Step-by-step explanation:
Given: Principal (P) = $3200, Annual Rate (R) = 4.1%, Time = 5 years
To find: How much money would he have in the account after 5 years, if he made no deposits or withdrawals during that time?
Formula: [tex]A = P(1 + r/n)^nt[/tex]
Solution: Compound interest is one of the most important concepts to understand when managing your finances. It can help you earn a higher return on your savings and investments, but it can also work against you when you're paying interest on a loan
First, convert R as a percent to r as a decimal
r = R/100
r = 4.1/100
r = 0.041 rate per year,
Then solve the equation for A
A = P(1 + r/n)[tex]^{nt}[/tex]
A = 3,200.00(1 + 0.041/12)[tex]^{(12)(5)}[/tex]
A = 3,200.00(1 + 0.003416667)[tex]^{(60)}[/tex]
A = $3,926.71
Hence, Jay would have $3,926.71 after 5 years is if he made no deposits or withdrawals during that time.
calculate the discount percent on an article which cost ¢60,000 but was reduced to ¢45,00
Answer:
Assuming you mean from $60 to $45, that would be 25%.
Step-by-step explanation:
We can use the simple formula: [tex]\frac{NEW-OLD}{OLD} *100[/tex]
In this case: [tex]\frac{45-60}{60} *100 = -25[/tex]
Which means there is a 25% discount.

Based on the table, which function models this situation?
a. f(n) = -3n + 24
b. f(n) = -(1/3)n + 16
c. f(n) = -3n + 64
d. f(n) = -(1/3)n + 8
please show how you got the answer!
Answer:
A is correct. f(n) = -3n + 24
Step-by-step explanation:
We can see in the first two steps that two meals have been served, and six cups of pet food consumed. In other words, six cups are consumed in two meals, therefore three cups are consumed in each meal.
If we look at the remaining numbers on the chart, we can see that this carries through. This tells us that the correct answer must be either a or b, as "-3n" represents the consumption rate. If it were (1/3)n, then only a third of a cup would be consumed per meal.
Finally, we can figure out which of those two equations is correct simply by plugging a value pair into them. Starting with a:
f(1) = -3(1) + 24
= 24 - 3
= 21
correct.
To be certain, let's check with answer c:
f(1) = -3(1) + 64
= 64 - 3
= 61
incorrect.
So we can clearly say that the correct answer is "a". You can plug the other values into it to test that too:
f(3) = -3(3) + 24
= 24 - 9
= 15
correct
So we definitely have the right answer.

Which group forms a rectangle of
[tex]Length = 15[/tex]
[tex]Width = 11[/tex]
First, calculate the area of the big rectangle
[tex]Area = Length * Width[/tex]
[tex]A_{Big} = 15 * 11[/tex]
[tex]A_{Big} = 165[/tex]
Next, calculate the area of each rectangle A to E.
[tex]A_A = 11 * 7[/tex]
[tex]A_A = 77[/tex]
[tex]A_B = 2 * 11[/tex]
[tex]A_B = 22[/tex]
[tex]A_C = 6 * 6[/tex]
[tex]A_C = 36[/tex]
[tex]A_D = 6 * 5[/tex]
[tex]A_D = 30[/tex]
[tex]A_E = 13 * 4[/tex]
[tex]A_E = 52[/tex]
Then consider each option.
(a) 3E + 2B
[tex]3E + 2B = 3 * 52 + 2 * 22[/tex]
[tex]3E + 2B = 156 + 44[/tex]
[tex]3E + 2B = 200[/tex]
(b) A + B + C + D
[tex]A + B + C + D = 77+22+36+30[/tex]
[tex]A + B + C + D = 165[/tex]
(c) 2C + 2D + 2B
[tex]2C + 2D + 2B = 2 * 36 + 2 * 30 + 2 * 22[/tex]
[tex]2C + 2D + 2B = 72 + 60 + 44[/tex]
[tex]2C + 2D + 2B = 176[/tex]
(d) A + 4B
[tex]A + 4B = 77 + 4 * 22[/tex]
[tex]A + 4B = 77 + 88[/tex]
[tex]A + 4B = 165[/tex]
(e) E + C + D + 3B
[tex]E + C + D + 3B = 52 + 36 + 30 + 3 * 22[/tex]
[tex]E + C + D + 3B = 52 + 36 + 30 + 66[/tex]
[tex]E + C + D + 3B = 184[/tex]
Recall that:
[tex]A_{Big} = 165[/tex]
Only options (b) and (d) match this value.
[tex]A + B + C + D = 165[/tex]
[tex]A + 4B = 165[/tex]
Hence, options (b) and (d) are correct
