Answer:
Lateral Area = 906.3
Surface Area = 461.8
Step-by-step explanation:
1. Find Values:
Diameter = 14
Radius = 7
Height = [tex]\sqrt{19^{2}-7^{2} }[/tex]=17.7
2. Find Lateral Area:
LA= [tex]\frac{1}{3}[/tex] * PI * [tex]r^{2}[/tex] * h
LA = 906.3
3. Find Surface Area:
SA = PI * r * slant height + (2 * PI * r)
SA = 461.8

Can someone please solve this? When I put it in the calculator the slope is wrong.
Answers
Answer:
y=6
Step-by-step explanation:
When you put the points on a plane, you can see it is a horizontal line, therefore the slope is 0
Remember that 0 times any other number is 0
So, instead of having y=0x+6 you can simplify the 0x and you have y=6
Tammy cuts four identical circles from a square piece of black poster board as shown. What is the area of the leftover poster board?
a) 6.240 square feet
b) 5.375 square feet
c) 18.760 square feet
d) 19.625 square feet
Answers
Answer:
B) 5.375
Step-by-step explanation:
The circles are half the square so their diameter will be half the length of the square
d=5/2=2.5
the formula is
area of shaded portion-area out unshaded portion
area of a square= l×l
5×5=25
area of a circle=πr^2
but since there are 4 circles it becomes 4πr^2
r=d/2=2.5/2=1.25
area of unshaded portion= 4×3.14×1.25×1.25
=19.625
area of leftover=25-19.625
= 5.375

Step-by-step explanation:A table can be completed by plugging x-values into an equation or by graphing.
Plug in x-values
First, plug 0 into the equation to find the first y-value.
y=5(0)y=0Next, plug in 1 for x
y=5(1)y=5Finally, plug in 2
y=5(2)y=10Additionally, each of these y-values increases by 5. So, once we found the first y-value, 0, we can just add 5 to find the next y-values.
Graphing
Also, you can use a graph to find the missing values. The y-intercept is 0 and the slope is 5. Using this information you can graph the equation. Then, find the x-values on the graph and match these values to y-values.

Answer:
1.3
Step-by-step explanation:
To find what x equals, you need to first divide by 48 and 37.
This is because that x is being multiplied by 37.
48 ÷ 37 = 1.297.......
The 97 in 1.297 is repeating and goes on forever.
Rounding the the nearest tenth would create the number 1.3 as the correct answer.

How does your Web browser get a file from the Internet?Your computer sends a request for the file to a Web server, and the Web server sends back a response.
For one particular Web server, the time X (in seconds) after the start of an hour at which a randomly selected request is received has the uniform distribution shown in the figure.
The probability of finding value less than the X is,
[tex]P(X < x)=\dfrac{x-a}{b-a}[/tex]
Here, a and b are two bonds of uniform distribution.
The probability distribution of X can be modeled by a uniform density curve on the interval from 0 to 3600 seconds, as shown in the given figure.
The probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour has to be found out. Thus,
[tex]P(X < x)=\dfrac{300-0}{3600-0}\\P(X < x)=0.0833\\P(X < x)=8.33\%[/tex]
Thus, the probability that the request is received by this server within the first 5 minutes (300 seconds) after the hour is 0.0833 or 8.33%.

How to write the recursive functionGiven the following parameters
a is the initial values = 30,000
If the amount doubles each year then b = 2
Let n be the number of years such that if the numbe r keeps doubling then:
an = 2n
First term a = 30000 (iniital value)

Answer: Choice C
Mean = 37.1
==================================================
Explanation:
Refer to the table below. The colum labeled "M" is the midpoint for each age interval. To find the midpoint, add up the endpoints and divide by 2. For example, the midpoint of 18 and 24 is (18+24)/2 = 42/2 = 21. Notice how the values of M are increasing by 7 each time.
The column labeled fM refers to multiplying the frequency f with the midpoint M. Example: fM = 6*21 = 126 in the first row.
Add up everything in the column labeled fM and you should get 1484. Divide this over the sum of the frequencies (40) and the mean is 1484/40 = 37.1

Every second, an elevator either has a 50% chance of going up and a 50% chance of going down. If the elevator starts at floor 15, what is the probability that, after 5 seconds, the elevator is at floor 18?
Answers
Using it's concept, it is found that there is a 0.1563 = 15.63% probability that, after 5 seconds, the elevator is at floor 18.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Starting at floor 15, these are the following outcomes that result in the elevator being at floor 18 in 5 seconds, each with [tex]0.5^5[/tex] probability:
4 up, 1 down.3 up, 1 down, 1 up.1 down, 4 up.1 up, 1 down, 3 up.2 up, 1 down, 2 up.5 outcomes, hence the probability is:
[tex]p = 5 \times (0.5)^5 = 0.1563[/tex]
0.1563 = 15.63% probability that, after 5 seconds, the elevator is at floor 18.

A circle is drawn inside a square.
20 cm
The square has a height of 20 cm.
Work out the shaded area.
Give your answer in terms of T.
Answers
So basically first you have to find the area of both the square and the circle which is 400 cm^2 and 100pi cm^2 respectively.
Then we subtract the area of circle from the square
So that becomes 400 - 100pi
Taking 100 common, 100(4 - pi)
Now this is for the 4 remaining corners
To get the area of the shaded region, divide the remaining area by 4
Now we get 25(4 - pi)
