Answer:
367.57 in³
Step-by-step explanation:
The formula for the volume of a cylinder is [tex]V = h\pi r^2[/tex], where V is the volume, h is the height, and r is the radius. The picture shows you that r = 3 in and h = 13 in.
Plug these into the formula to find the answer:
[tex]V = (13)\pi 3^2=(13)(9)\pi =117\pi => 367.566[/tex]
Round that to the nearest hundredth to get 367.57. The units for the answer should be in cubic inches.
For the surface area, imagine laying the cylinder out. You'd see two circles, for the top and bottom, and then a rectangle, which is the side. The formula is A=2πrh+2πr². Try to do this yourself! You only need to plug in the values: r = 3 in and h = 13 in.

(c) Find the probability that at least one of the two adults thinks most celebrities are good role models. The probability that at least one of the two adults thinks most celebrities are good role models ______? (Round to three decimal places as needed.)
Answer:
A) 0.062
B)0.564
C)0.436
Step-by-step explanation:
There are 800 US adults sampled and 199 think that most celebrities are good role models.
Now, two are selected without replacement.
Thus;
A) Probability that both adults think most celebrities are good role models would be = (199/800) × (198/799) = 39402/639200 = 0.062
B) we want to find probability that neither adult thinks most celebrities are good role models.
Now, since 199 out of 800 think that most celebrities are good role models..
Thus, number that doesn't think most celebrities are good role models = 800 - 199 = 601
probability that neither adult thinks most celebrities are good role models. would be = (601/800) × (600/799)= 180300/319600 = 0.564
C) We want to find the probability that at least one of the two adults thinks most celebrities are good role models.
Now, since we already have the probability that neither of them thinks most celebrities are good role models, we will just subtract that probability from 1.
Thus;
probability that at least one of the two adults thinks most celebrities are good role models = 1 - 0.564 = 0.436
what is the Transformation of a function?
Answers
Answer:A function transformation takes whatever is the basic function f (x) and then "transforms" it (or "translates" it), which is a fancy way of saying that you change the formula a bit and thereby move the graph around. Moving the function down works the same way; f (x) – b is f (x) moved down b units.

f(x) = -×-3
find f(-4)
Answers
Answer:
Hey there!
Original function: f(x)=-x-3
Substituting -4: f(-4)=4-3
Simplify: f(-4)=1
Let me know if this helps :)
F(x) = -x - 3
F(-4)
Replace x with -4 and solve:
F(-4) = -(-4) -3
-(-4) = positive 4
So you have 4-3
4-3 = 1
F(-4) = 1

A city council consists of six Democrats and seven republicans. If a committee of four people is selected, find the probability of selecting two Democrats and two Republicans.
Answers
Answer:
[tex]\bold{\dfrac{63}{143}}[/tex]
Step-by-step explanation:
Number of Democrats = 6
Number of Republicans = 7
Total number of members = 6+7 = 13
To find:
Probability of selecting two Democrats and two Republicans if 4 members are selected in the committee = ?
Solution:
This is a selection problem.
Total number of ways to select 4 members in the committee out of total 13 = [tex]_{13}C_4 = \dfrac{13\times 12\times 11\times 10}{4\times 3\times 2} = 715[/tex]
Number of ways to select 2 Democrats = [tex]_{6}C_2 = \dfrac{6\times 5}{2} = 15[/tex]
Number of ways to select 2 Republicans = [tex]_{7}C_2 = \dfrac{7\times 6}{2} = 21[/tex]
Number of ways to select 2 Democrats and 2 Republicans = 15 [tex]\times[/tex] 21 = 315
Formula for probability of an event E can be observed as:

We need to find the value of given limit problem.
Taking limit, we get

In which situation is it best to use a line graph?
A): when the values on both axes are numbers
B): when a grade distribution is displayed
C): when showing trends
D): when representing parts of a whole
Answers
Answer: C): when showing trends
Step-by-step explanation:
A Line graph connects different points such that it appears as a line. For this reason it is very useful in showing the trend in the movement of values overtime.
When plotting line graphs the independent variable for example 'months' is usually put on the x-axis and a dependent variable such as 'temperature' will be on the y-axis.
When plotted, the line will be able to show just how things have changed overtime such that the change is quite easy to see through the movement of the line.

Step-by-step explanation:
If the investments were in the ratio 3:5, the returns on those investments were ...
3×0.08 +5×0.10 = 0.74 . . . . . ratio units
This return is $92,000, so each ratio unit of investment is ...
$92,000/0.74 = $124,324.32 (and change)
The total investment was 8 ratio units, so was ...
$124,324.32 × 8 = $994,594.59 . . . . total amount invested.
_____
Check
3/8 of the invested amount earned 8%, so that interest was ...
$994,594.59×(3/8)×(0.08) = $29,837.84
5/8 of the invested amount earned 10%, so that interest was ...
$994,594.59×(5/8)×(0.10) = $62,162.16
The total interest earned was $29,837.84 +62,162.16 = $92,000.

The correct answer is D. 73 • 5 • 74
Explanation:
In mathematics, multiplication can be represented by using the symbol × or the symbol ·. Moreover, multiplication can be also represented just by leaving the numbers or values side by side without any symbol. For example, the expression 5x + y implies 5 should be multiplied by x. In this context, the expression (73)5 • 74 indicates 5 should be multiplied by 74, and the result of this should be multiplied by 73 as the lack of symbol indicates multiplication. Therefore, this is equivalent to 73 • 5 • 74.

Rosa had 4 dozen beads. She split them into 6 equal groups and gave two groups to her friend. How many beads did Rosa have then?
Answers
Answer: 32
Step-by-step explanation:
4 dozen beads is 48 beads. Divide 48 into 6 groups, and your answer is 8. If Rosa gave 2 groups to her friend, she gave 16 beads, which leaves her with 32 beads.
Answer: 32
Step-by-step explanation:
1 dozen = 12.
4 dozen x 12 = 48.
48 ÷ 6 = 8
If she gave two groups of 8 beads, that is 16 beads.
48 beads - 16 beads = 32 beads.
The answer is 32 beads.
