A 5-column table has 3 rows. The first column has entries hardcover, paperback, total. The second column is labeled Fiction with entries 28, 4, 32. The third column is labeled biographies with entries 2, 1, 3. The fourth column is labeled Reference with entries 10, 15, 25. The fifth column is labeled Total with entries 40, 20, 60.
What is the probability that a randomly selected reference book is hardcover?
0.25
0.4
0.6
0.75
Answers
The probability that a randomly selected reference book is hardcover is 0.4.
The two-way table depicts the distribution of books in Eliza's home by type (hardcover, paperback, biographies, fiction, and reference), as well as the number of books in each category (32 fiction books, 3 biographies, and 25 reference books).
There are a total of 25 reference books, of which 10 are hardcover.
So the probability that a randomly selected reference book is hardcover is:
10/25 = 0.4
Therefore, the probability is: 0.4.

Jeff modeled the number of minutes that he read each day during the first week of the summer. The recursive function, f(x), can be used to determine the number of minutes that he had read after a certain number of days, where x represents the number of days. f(1) = 28 f(x) = f(x - 1) + 8 Use the recursive function to find the number of minutes that Jeff read after 3 days of summer.
Answers
9514 1404 393
Answer:
44 minutes
Step-by-step explanation:
We are given f(1) = 28.
Using the recursive formula ...
f(2) = f(1) +8 = 28 +8 = 36
f(3) = f(2) +8 = 36 +8 = 44
Jeff read 44 minutes after 3 days of summer.
Find the values of a and b so that the linear system has the given solution.
Given Solution: (2, 1)
Equation 1: ax - by'= 4
Equation 2: bx - ay = 10
Answers
Answer:
The values are a=6, b=8
Step-by-step explanation:
System of Equations
We are given the system of equations:
ax - by = 4
bx - ay = 10
And it's known the solutions are: x=2, y=1.
Plugging in the solutions:
2a - b = 4 [1]
2b - a = 10 [2]
Now we have to solve the system above. Multiply [1] by 2:
4a - 2b = 8
Now we add with [2]:
3a = 18
a = 18/3 = 6
a = 6
From [2]:
2b - 6 = 10
2b = 16
b = 16/2 = 8
b = 8
The values are a=6, b=8

to compound 50% solution in which proportion must 95% sol and 30% sol be mixed to make
500 ml
Answers
Answer:
4/9
Step-by-step explanation:
Let the amount of 95% sol = a ml and
the amount of 30% sol = b ml.
So, the total amount of the compound=a+b=500 ml
As the compound is 50% solution, so
95% of a + 30% of b= 50% of (a+b)
(95/100)a+(30/100)b=(50/100)(a+b) [from equation (i)]
95a + 30b = 50(a+b)
95(a/b)+30 = 50(a+b)/b [dividing both sides by b]
95(a/b)+30 = 50(a/b+1)
95(a/b)+30 = 50(a/b)+50
95(a/b)-50(a/b)=50-30
45(a/b)=20
a/b=20/45
a/b=4/9
Therefore, a:b=4:9
As a+b= 500 ml, so the amount of 95% sol = [tex]\frac {500}{13}\times 4=\frac{2000}{13}=153.85[/tex] ml
and the amount of 95% sol = [tex]\frac {500}{13}\times 9=\frac{4500}{13}=346.15[/tex] ml
Hence, the proportion of 95% sol and 30% sol to make a compound of 50% sol must be 4/9.

Answer:
Store A
Step-by-step explanation:
Store A
50/100=0.5
0.5×5=2.5
The watch will be 50-2.5=47.5
Store B
60/100=0.6
0.6×20=12
The watch will be 60-12=48
So the watch price in store A is better
Answer:
You should buy from Store A because you're paying $0.50 less than if you were to buy from Store B.
Step-by-step explanation:
First, don't subtract if it's a percentage. You will want to multiply to get the amount you're removing from the original price.
Let's look at Store A. $50 and 5% discount. 50 * 0.05 = 2.5. Remove 2.5 from 50.
50 - 2.5 = 47.5
When you buy from Store A, you will pay $47.5
Let's look at Store B. $60 and 20% discount. 60 * 0.20 = 12. Remove 12 from 60.
60 - 12 = 48
When you buy from Store B, you will pay $48
Ultimately, Store A is the best option because you're paying less.
