Problem 2 Charlie estimates the height of a building to be 924 feet. Charlie's father tells him that his estimate has a 20% error. Explain why this is not enough information for Charlie to find the actual height of the building. Based on this information, what are the two possible values for the actual height of this building?
The actual height of the building is 739.2 feet.
Given the height of a building estimated by Charlie is 924 feet.
His father said that there is 20% error in the estimation.
we should determine 20% of the estimated height.
⇒ height = 924 feet
⇒ error = 20%
⇒ 924 × 20/100
⇒ 924/5
= 184.8 feet
Subtract the error in height with the height given.
⇒ estimated height - error in height
⇒ 924 - 184.8
= 739.2 feet.
hence the actual height is 739.2 feet.

-4, -1/2, 3, 13/2, 10,… represents an arithmetic sequence.
An arithmetic sequence progresses with a common difference which is the difference of consecutive terms.
So for each of the number sequences, we will try to check if the consecutive terms has a common difference.
A) 32, 16, 8, 4, 2,...
16-32 = -16
8-16 = -8

if test scores for an exam were normally distributed with a mean of 75 and a standard deviation of 5, find the probability that a randomly selected student scored less than 82
The probability that a randomly selected student in the class test scored marks which is less than 82 is 0.9192
It is given that in a test, the scores for an exam normally distributed has a mean of 75 and a standard deviation of 5. We have been asked to find the probability that a randomly selected student scored less than 82.
From the question we have,
Mean = 75
Standard deviation (SD) = 5
Therefore, the probability that a randomly chosen student has a score of less than 82 is represented as:
(P) Probability ( X < 82) = P { Z < [tex]\frac{82-75}{5}[/tex] }
= P {Z < 7/5}
= P {Z <1.4}
= Area from - ∞ to 1.4
= 0.9192
From the z table the area under the normal curve that corresponds to 1.4 is 0.9192
Hence the required probability of that a randomly selected student scored less than 82 is 0.9192

A line with a perpendicular slope with have a slope that is the negative inverse of the reference line. If the reference line is -(2/3), the perpendicular line will have a slope of (3/2).
The line formed by ab: y = (3/2)x + b
We have one given point on line ab with one coordinate known, (3,4), so let's use it to find b:
y = (3/2)x + b
4 = (3/2)*3 + b for (3,4)
4 = (9/2) + b
b = 4 - (9/2)
b = - 0.5
The equation is y = (3/2)x - 0.5
The slope of (3/2) is equal to the Rise/Run of two points on the line: (3,4) and (w,-5):
Rise = (4 - (-5)) = 9
Run = (3 - w)
Slope = 9/(3-w)
(3/2) = 9/(3-w)
(3/2)(3-w) = 9
(9/2) - (3/2)w = 9
9 - 3w = 18
-3w = 9
w = -3
Point b is (-3, -5)

The slope is the rate of change. It tells us how fast y increases.
slope = rise/run = 20 = 20/1
rise = 20 = increase the earnings by 20 dollars

If we know the time, we can plug in the value for "t" in the above derivative and find how much water drained for the given point of t.
Given:
V =2000( 1- (1/40)t)^2 , where 0≤t≤40.
Here we have to find the derivative with respect to "t"
We have to use the chain rule to find the derivative.
V'(t) = 2 (2000)(1- (1/40)t)d/dt(1- (1/40)t)
V'(t) = 2(2000)(1-(1/40)t(-1/40)
When we simplify the above, we get
V'(t) = -250(1-(1/40)t)
If we know the time, we can plug in the value for "t" and find how much water drained for the given point of t.

The percentage increase in the cost of the airline tickets is 38%.
What is the percentage increase?Percentage is the fraction of a number out of hundred. The sign that is used to represent percentages is %. Percentage is a measure of frequency. In order to convert a value to a percentage, multiply the value by 100.
in order to determine the percentage increase, multiply the fraction of the change in price and the initial price by 100.
Percentage increase = (change in price / initial price) 100
Change in price = new price - initial price = $310 - $225 = $85
Initial price = $225
($85 / $225) x 100 = 38%
