Pamela has 15 different books. In how many ways can she place her books on two selves so that there is at least one book on each shelf? (Consider the books in each arrangement to be stacked one next to the other, with the first book on each shelf at the left of the shelf.)
Initially, I thought that this would be fairly straight forward. There are two cases where either shelf could be empty and so we would subtract 2 from the total number of permutations which is obviously 15!. It is obvious now that both of these statements are false.
My previous thoughts didn't take into account the fact that there are two shelves and that the books could be stacked in such a way that 5 are on the top shelf and 10 are on the bottom, or 8 on top with 7 on bottom, or any number of other ways. I believe there are 214 ways the books can be distributed amongst the two shelves (keep in mind that each shelf has to have at least one book, 15−1=14) if the ordering of the books didn't matter, but it does. Is this correct?
six times jason collection of books and one third of nathan collection add up to 134 books. one third of jason collection and nathans entire collection add up to 31 books
Answer:
j = 21 and n = 14
Step-by-step explanation:
we have the equations:
6j + n/3 = 134
j/3 + n = 31
54j + 3n = 1206
j + 3n = 93
53j = 1113
j = 21
(21)/3 + n = 31
7 + n = 31
n = 14

Step-by-step explanation:
The local monsters are currently throwing a bash
known as the Monster Mash. At the beginning of the
party, there were 5 monsters attending. At the end
of the party there were 225 monsters. If an average
4 monsters came to the bash every minute of the
party, how long did this Graveyard Smash last?
Answer: 55 minutes
Step-by-step explanation:
First, you would have to subtract 5 from 225 because there are already 5 monsters there.
225-5= 220
Next, you would have to divide 220 by 4 to find the amount of minutes.
220/4= 55

a-2=3+6a/3
What’s the value of a?
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Linear Algebra
a-2= 3+6a/3
=> 3(a-2)= 3+6a
=> 3a-6= 3+6a
=> -6-3=6a-3a
=> -9=3a
hence, a=-3
Over spring break, Shane works as a lifeguard at his community pool.He works 16.25 hours every week of his 2-week break. He puts
2
5
of his earnings toward a new computer. If he makes $13 per hour, how much money does he save for his computer?
Answer:
$169
Step-by-step explanation:
Multiply 16.25 x 2 so you can find how many hours he worked
32.50 hours, so now you multiply that by 13 so you know how much money he earned
$422.50, so now you multiply 2/5 x 422.50
Your answer will be 169 dollars
Answer:
169
Step-by-step explanation:
(-12,8), (9,1)
What is the point-slope form of the equation of the line?
Answer:
y-y1 = m (x-x1)
where
m is the slope
and (x1,y1) is one of the points given.
You have been given 2 points (-12,8) and (9,1). You can call one of them (x1,y1) and the other (x2,y2). It doesn't matter which one is which.
But before we go further, we need to determine the slope.
We can do this from the points as well.
y2-y1
m = ---------
x2-x1
Let's say
(x1,y1) = (-12,8)
(x2,y2) = (9,1)
This gives us a slope of
y2-y1 1-8 -7 -1
m = --------- = ---------- = ---- = ---
x2-x1 9-(-12) 21 3
Now that we have everything we need
y-8 = (-1/3)[x-(-12)]
Distribute the -1/3
y-8 = (-1/3)x -4
If we add 8 to both sides we have the equation in the slope intercept form (y=mx+b)
y = (-1/3)x + 4

f(x) = 2x + 7 - x^2 over 4
f(2) = ?
f(x) = [tex]\frac{2x + 7 - x^2}{4}[/tex]
f(2) just means we substitute 2 in for x.
f(2) = [tex]\frac{2(2) + 7 - (2)^2}{4}[/tex] = [tex]\frac{4 + 7 - 4}{4}[/tex] = [tex]\frac{7}{4}[/tex]

Answer:
1.80 + 3.72 (0.25 x b) = 13.02
Step-by-step explanation:
First, combine the "one-time" costs (the medium pendant and the medium chain)
1.80 + 3.72 = 5.52
Now, multiply the cost of the beads by the amount of beads you want
0.25 x 30 = 7.50
Now combine both costs to get the total cost
5.52 + 7.50 = 13.02
It would cost Tamara $13.02 to make a medium length necklace
A delivery company is logging the number of miles each employee drives each day. The company found an average of about 85.6 miles. Assume that the standard deviation is 9.85 miles and that a random sample of 50 drivers was used to determine the average. Which statements are true about this situation?
The 99% confidence interval is from about 81.43 to 90.58 miles.
The 95% confidence interval is from about 82.87 to 88.33 miles.
The margin of error for 99% confidence is about 3.59 miles.
The sample isn’t large enough to use a normal distribution.
The margin of error for 95% confidence is about 2.52 miles.
Answer:
B. The 95% confidence interval is from about 82.87 to 88.33 miles.
C. The margin of error for 99% confidence is about 3.59 miles.

Which choice is a reasonable product for the expression 8 x 2.48 ?
O 1.984
19.84
198.4
0 1984
Explain why your choice is correct using words and numbers.
Answer:
8 x 2.48 = 19.84
Step-by-step explanation:
We need to find the product for the expression 8 x 2.48.
First no is 8 and second no is 2.48
Product means to multiply.
We can write 2.48 as [tex]\dfrac{248}{100}[/tex]
i.e.
[tex]8\times \dfrac{248}{100}\\\\=\dfrac{1984}{100}[/tex]
Now, apply decimal after 9. So,
8 x 2.48 = 19.84
Hence, the correct option is (b).
