On solving the provided question, we can say that Probability(A and B) = P(A)P(B|A) and P(E or F) = P(E) + P(F) - P(E and F)
What is probability?Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur. Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1. the percentage of occurrences in a complete set of equally likely possibilities that result in a certain occurrence compared to the total number of outcomes.
Probability(A and B) = P(A)P(B|A).
P(A and B) = P(B and A), this may also be written as P(A and B) = P(B)P(A|B).
Using the general multiplication rule, we have
P(E and F) = P(E)P(F|E)
.392 = P(E)(.7)
P(E) = .56
P(E and F) = P(F)P(E|F)
.392 = P(F)(.56), so
P(F) = .7
P(E or F) = P(E) + P(F) - P(E and F)

A zoologist recorded the speed of two cheetahs. Cheetah A ran 17 miles in 8 minutes. Cheetah B ran 56 miles in 20 minutes. Which statement is correct?
Cheetah A has a higher ratio of miles per minute than Cheetah B because 17 over 8 is less than 56 over 20.
Cheetah B has a higher ratio of miles per minute than Cheetah A because 17 over 8 is greater than 56 over 20.
Cheetah B has a higher ratio of miles per minute than Cheetah A because 17 over 8 is less than 56 over 20.
Both cheetahs have the same ratio of miles per minute.

High school track athlete sprints 100 yards in 15 seconds if there are 5280 feet in a mile and 3600 seconds in an hour, determine the runner speed in miles per hour. Round to the nearest 10th.
The runners speed in miles per hour is 13.6 mph .
In the question ,
it is given that
the high school track athlete sprints 100 yards in 15 seconds
we remember that 1 yard = 3 feet
So, 100 yard = 3*100 = 300 feet
in the question it is given that
5280 feet = 1 mile
1 feet = 1/5280 mile
So, 300 feet = 300/5280 mile
and 3600 second = 1hour
1 second = 1/3600 hour
15 seconds = 15/3600 hour
So, the speed of the runner = (300/5280 mile ) / (15/3600 hour )
= (300/5280) * (3600/15)
On simplifying further ,
we get
= 13.636363
≈ 13.6
Therefore , The runners speed in miles per hour is 13.6 mph .

In the diagram, A is a point on the circumference of a circle with center O and radius r. A circular are with center A meets the circumference at B and C. The angle O A B is θ radians. The shaded region is bounded by the circumference of the circle and the are with center A joining B and C. The area of the shaded region is equal to half the area of the circle.
The area of the shaded region is equal to half the area of the circle.
What is the area of the circle?
The approximating parallelograms arbitrarily close and approximate the area of the circle by cutting it into ever-increasing slices.
The radius of the arc BC is |AB|=2rcosθ, and ∡AOB=π−2θ.
Dashed area= Area of sector BAC+ 2(Area of sector BOA−Area of triangleBOA)
= 1/2|AB|²(2θ)+2[1/2r²(π−2θ)−1/2r²sin(π−2θ)]
On the other hand, the area of the dashed surface is 1/2πr², then
1/2|AB|²(2θ)+2[1/2r²(π−2θ)−1/2r²sin(π−2θ)] = 1/2πr²
(2rcosθ)2(θ) + r²[π−2θ−sin(π−2θ)] = 1/2πr²
4θcos2θ+π−2θ−sin2θ = 1/2πr²
2θ(2cos2θ−1) = sin2θ−1/2π
2θcos2θ = (2sin2θ−π)/2
cos2θ = (2sin2θ−π)/4θ
Hence, the area of the shaded region is equal to half the area of the circle.

Procedures that help organize or describe data collected from a sample or a population are called Descriptive statistics.
Hence, option D is correct answer.
Descriptive statistics and examples: what are they?Data can be meaningfully and effectively described or summarised using descriptive statistics. For instance, knowing that everyone in our scenario wore blue shoes wouldn't be helpful. It would be helpful to know how evenly distributed their anxiety scores were. Measures of central tendency and measurements of variability make up descriptive statistics (spread).
The mean, median, and mode are measurements of central tendency, while the standard deviation, variance, minimum and maximum variables, kurtosis, and skewness are measures of variability.
Why do we utilise descriptive statistics?
In order to emphasise potential correlations between variables and to give basic information about the variables in a dataset, descriptive statistics can be helpful for both of these aims.

Answer:

Step-by-step explanation:
find the perimeter of the rectangle: 4m and 4m
Given data
Lenght = 4m
Breadth = 4m
The formula for the perimeter of a rectangle
\(\begin{gathered} \text{Perimeter = 2}\times\text{ Length + 2 }\times\text{ breadth} \\ =\text{ 2 }\times\text{ 4 + 2 }\times\text{ 4} \\ =\text{ 8 + 8} \\ =\text{ 16 meters} \end{gathered}\)The result of the perimeter is 16 meters (m).
Step-by-step explanation:To solve, we must first know that the perimeters in this problem should only be added to each side, which is 4, where it gives a result of 16 meters (m).
¿What are the perimeters?First of all we must know that in geometry, the perimeter is the sum of all the sides. A perimeter is a closed path that encompasses, surrounds, or skirts a two-dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.
With this we can say that the perimeters are those that are added from each side, so, what we need to do in this problem is just just add each side, each side is four, so we can add it by 4 since it asks us for that.
\( \bold{4 + 4 + 4 + 4 = \boxed{ \bold{16m}}}\)
But we also have another step to solve this problem, which is just squaring it where it also gives us the same result, let's see:
\( \bold{2 {}^{4} = \boxed{ \bold{16 \: meters \: (m)}}}\)
So, as we see, each resolution gives us the same result, therefore, the result of the perimeter is 16 meters (m).

The events are independent because P(blue). P(green) = P(blue and green).
The events are independent because P(blue). P(green) + P(blue and green).
The events are dependent because P(blue). P(green) = P(blue and green).

Two events are said to be dependent if the outcome of the second is affected by the outcome of the first thereby causing the probability to change.
For probability without replacement, the probability for the second event changes. Therefore, the events are dependent
For B and G to be dependent events, we would assume the Ist marble wasn't replaced before picking another, thereby reducing the total marbles for the 2nd event from 4 to 3.
The probability of both events occurring is the product of the probabilities of the individual events = 1/4 ×1/3 = 1/12
Two events are said to be independent if the outcome of the second event is not affected by the outcome of the first event. Probability with replacement falls under this (in thus case, that is the 1st marble is replaced before picking another)
For B and G to be independent events, the probability of both events occurring is the product of the probabilities of the individual events = 1/4 ×1/4 = 1/16
Therefore, the events are dependent because P(blue). P(green) = P(blue and green) (C)
