Using the 68-95-99.7 rule
PROBLEM: The random variable
* = the stopping distance of a randomly
selected emergency stop for a pickup
truck on dry pavement from a speed of
62 mph can be modeled by a normal
distribution with u = 155 ft and
o= 3 ft. Use the 68-95-99.7 rule
to approximate:
(a) P(x > 158)
(b) The probability that a randomly
selected emergency stop is between 149 ft
and 152 ft.
Using the Empirical Rule, it is found that the desired probabilities are given as follows.
a) P(x > 158) = 0.16.
b) P(149 < x < 152) = 0.135.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.Additionally, considering the symmetry of the normal distribution, 50% of the measures are below the mean and 50% are above.
Item a:
158 is one standard deviation above the mean, hence the probability is given by, considering that 32% of the measures are more than 1 standard deviation from the mean:
P(x > 158) = 0.5 x 0.32 = 0.16.
Item b:
Between one and two standard deviations below the mean, hence:

In the scenario described, the standard deviation would be 2.74.
What is the standard deviation?A measurement of a data set's deviation from the mean is referred to as "standard deviation".
Whereas a high standard deviation indicates that the data are more spread, a low standard deviation suggests that the data are clustered around the mean.
It displays the standard deviation of each score with respect to the mean.
A high standard deviation in a normal distribution indicates that values are frequently outside of the mean, whereas a low standard deviation indicates that values are clustered closely around the mean.
The standard deviation formula is as follows:
standard deviation = √np(1-p)
Assuming that p = 0.75 and n = 40, the following is the standard deviation:
standard deviation = √np(1-p)
standard deviation = √(40)(0.75)(1-0.75)
standard deviation = 2.74

12. A plot of land is used to grow flowers. of the land is allocated for orchids. 2 After the orchids have been planted, of the remaining land is allocated for roses. After orchids and roses have been planted, 0.75 of the remaining land is allocated for tulips. What fraction of the plot of land is not occupied by the flowers?
The fraction of the plot of land not occupied by the flowers is 0.0625 or 1/16.
Let's calculate the fraction of the plot of land that is not occupied by the flowers.
Given that initially, 1/4 of the land is allocated for orchids, we have 1 - 1/4 = 3/4 of the land remaining.
After planting the orchids, 2/3 of the remaining land is allocated for roses. Therefore, the fraction of land allocated for roses is (2/3) * (3/4) = 2/4 = 1/2.
Subtracting the land allocated for roses from the remaining land, we have 3/4 - 1/2 = 1/4 of the land remaining.
Finally, 0.75 of the remaining land is allocated for tulips. Therefore, the fraction of land allocated for tulips is 0.75 * (1/4) = 0.1875.
To find the fraction of the plot of land not occupied by the flowers, we subtract the fractions of land allocated for flowers from 1:
1 - (1/4 + 1/2 + 0.1875) = 1 - 0.9375 = 0.0625.
Therefore, the fraction of the plot of land not occupied by the flowers is 0.0625.

The amount of a pollutant (measured as parts per million) in a local lake can be modeled by the function of A(t)=14(2.71)^-.016*t, where t is the number of years since a government program was began to help clean up the lake. About how long will it take for the amount of pollutant to reach 7 parts per million?
Solving the exponential function, it is found that it will take 43.5 years for the amount of pollutant to reach 7 parts per million.
What is the exponential function for the amount of the substance?It is given by, after t years:
\(A(t) = 14(2.71)^{-0.016t}\)
It will reach an amount of 7 parts per million when A(t) = 7, hence:
\(A(t) = 14(2.71)^{-0.016t}\)
\(7 = 14(2.71)^{-0.016t}\)
\((2.71)^{-0.016t} = 0.5\)
\(\log{(2.71)^{-0.016t}} = \log{0.5}\)
\(-0.016t\log{(2.71)} = \log{0.5}\)

Each piece Measurement of an angle of 120 degrees cut into nine equal lengths with a kerf width of 0.125 would be 14.4583 degrees.
When a particular angle is cut into nine equal parts, the measure of each piece needs to be calculated.
Therefore, it is essential to first calculate the total angle measure and then divide it by the number of parts into which it is being cut.
What is an Angle?
An angle is a geometrical shape that consists of two rays sharing a common endpoint. The common endpoint is known as the vertex, and the two rays are known as the arms of the angle. An angle can be measured in degrees, radians, or gradians. Degrees are the most commonly used unit of measuring angles.How to Calculate Each Piece Measurement of an Angle if Cut into 9 Equal Lengths
To determine each piece measurement of an angle if cut into nine equal lengths, we will need to carry out the following steps:
Step 1: Calculate the total angle measure Suppose the angle being cut into nine equal lengths is an obtuse angle measuring 120 degrees. In that case, the total angle measure will be 120 degrees.
Step 2: Divide the total angle measure by the number of parts into which it is being cut.120 degrees ÷ 9 = 13.3333 degrees
Step 3: Add the kerf width to the piece measurements.0.125 x 9 = 1.125 degrees13.3333 + 1.125 = 14.4583 degrees
Therefore, each piece measurement of an angle of 120 degrees cut into nine equal lengths with a kerf width of 0.125 would be 14.4583 degrees.

A pound of rice has a mixture of two types of rice, each costing $10 and $30, if the average cost per is $24, what is the ratio of the different types of rice?
Answer:
3:7
Step-by-step explanation:
Let x = pounds of the $10 rice in the mixture
Let y = pounds of the $30 rice in the mixture
Total cost of the $10 rice = 10x
Total cost of the $30 rice = 30y
(10x + 30y) / (x + y) = 24
Solve this equation for y/x:
10x + 30y = 24(x + y)
10x + 30y = 24x + 24y
30y - 24y = 24x - 10x
6y = 14x
y/x = 6/14 simplify the fraction
y/x = 3/7
So, the ratio of the two different types of rice (y:x) is 3:7, meaning a pound of the rice mixture has 3 parts of the $30 rice to 7 parts of the $10 rice.

The horns are frequently used as a signal to indicate the end of a segment or a specific task. Hence, a horn blows is the noise that sounds at the end of a segment.
The noise that sounds at the end of a segment is A horn blows.
In geometry, a segment is a part of a line that connects two points.
For example, line segment AB, which is denoted by AB, connects point A and point B and can be visualized as a portion of a line.
In general, line segments are denoted by their endpoints.
A horn is a cone-shaped instrument that is often used as a warning signal or a musical instrument.
However, it is important to note that noise can occur at the end of a segment in certain contexts and situations.
For example, in the context of audio or video editing, you can apply fade-out effects or specific sound effects to signal the end of a segment.
However, these sounds are not universally applicable and depend on the specific creative choices and technical aspects of the project.
In the transportation sector, horns are commonly used to alert pedestrians and other drivers of an oncoming vehicle's presence.
The sound of a horn is usually a sharp and loud noise that is difficult to ignore.
As a result, horns are frequently used as a signal to indicate the end of a segment or a specific task. Hence, a horn blows is the noise that sounds at the end of a segment.
