The number 18 is decreased to 16. What is the percentage by which the number was
decreased, to the nearest tenth of a percent?
Answer:
11.1 %
Step-by-step explanation:
2/18 = 11.1%
The percentage of the number decreased is 11.1%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Initial number = 18
Final number = 16
The change in the value of the number.
= 18 - 16
= 2
The percentage decreased.
= (Change in the number / Initial number) x 100
= 2/18 x 100
= 200/18
= 11.11%
= 11.1 %
Thus,
The percentage decreased is 11.1%.

The volume of a cylinder is 980 in cubed.
The height of the cylinder is 20 in. What is the radius of the cylinder?
Express your answer to the nearest hundredth.
9514 1404 393
Answer:
3.95 in
Step-by-step explanation:
The volume is given by ...
V = πr²h
Solving for radius, we get ...
r = √(V/(πh))
For the given numbers, the radius is ...
r = √(980 in³/(π·20 in)) = 7/√π in ≈ 3.95 in
The radius of the cylinder is about 3.95 inches.

A 4-column table with 3 rows. Column 1 has entries bad weather, good weather, total. Column 2 is labeled heavy traffic with entries 25, 55, 80. Column 3 is labeled Light traffic with entries 5, 15, 20. Column 4 is labeled Total with entries 30, 75, 100. The columns are titled daily traffic and the rows are titled weather conditions.
Suppose a day from this city is selected at random. Let event A = heavy traffic and event B = bad weather. Are events A and B independent?
No, P(A) = P(B|A).
No, P(A) ≠ P(A|B).
Yes, P(A) = P(A|B).
Yes, P(A) ≠ P(B|A).
Answer:
I believe the answer is (B).
Both are not independent, and the probability of A is 30/100.
While the probability for A|B is like 30/100(80/100) which does not equal 30/100.
I've been trying to figure out how to do it and stuff, and this seems the most reasonable answer. I'm taking it now. Goodluck

The two events are not independent as the traffic is affected by the weather conditions.
What is independent probability?Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B).
Let event A = heavy traffic and event B = bad weather.
P(A)= 25/30 and P(B)=25/30
Two events are said to be independent only when the change in one event affect the other event.
Here the two given events are not independent.
Band weathers such as heavy rainfall, snowfall etc. leads to failure of traffic management system and thereby causes heavy traffic. This is easily seen in all major urban cities.
Hence, the two events are not independent as the traffic is affected by the weather conditions.

Write the equation of the line that passes throught the points (-1, 6) and (5, -4).
Answer:
y = -5/3x + 13/3
Step-by-step explanation:
(-1, 6) and (5, -4).
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-4 - 6) / (5 - (-1))
Simplify the parentheses.
= (-10) / (5 + 1)
= (-10) / (6)
Simplify the fraction.
-10/6
= -5/3
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = -5/3x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (5, -4). Plug in the x and y values into the x and y of the standard equation.
-4 = -5/3(5) + b
To find b, multiply the slope and the input of x(5).
-4 = -25/3 + b
Now, add 25/3 to both sides to isolate b.
-4 ⇒ -12/3
-12/3 + 25/3 = 13/3
13/3 = b
Plug this into your standard equation.
y = -5/3x + 13/3
This is your equation.
Check this by plugging in the other point you have not checked yet (-1, 6).
y = -5/3x + 13/3
6 = -5/3(-1) + 13/3
6 = 5/3 + 13/3
6 = 18/3
6 = 6
Your equation is correct.
Hope this helps!

Answer:
Read answer below :)
Step-by-step explanation:
So you know that the height is 12 cm, and the base is 27 cm at full. When they show you half, that's 13.5. So, having three sides in the entire base-length of 27 cms, you'll divide 27 by 3, in which case you get 9. Each the the base lengths are 9.
So the formula for volume is length * width * height. Knowing the width (13.5), the length (9), and height (12), multiply them. Your final answer is 1458 for all of it. For one side, divide by 6.
