a) The probability of having at least 1 rotten strawberry among the 5 is 0.262.
b) 1 strawberry must be picked so that the probability of having exactly 2 rotten strawberries among them equals 2/35.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.
The probability that Kyle selects exactly k rotten strawberries among the five she randomly picks is -
P( exactly k rotten strawberries) = [tex]\frac{(^2c_k)(^{34}c_{5-k}) }{^{36}c_5}[/tex]
since if she picks k of the 2 rotten strawberries, Kyle must also select 5 - k of the 36 -2 = 34 good strawberries.
Therefore, the probability that Kyle picks at least one rotten strawberry is -
P(at least 1 rotten strawberry) = P(exactly 1 rotten strawberry) + P(exactly 2 rotten strawberries)
P(at least 1 rotten strawberry) =[tex]\frac{(^2c_1)(^{34}c_{4}) }{^{36}c_5} + \frac{(^2c_2)(^{34}c_{3}) }{^{36}c_5}[/tex]
P(at least 1 rotten strawberry) = [(2 × 46376) / 376992] + [(1 × 5984) / 376992]
P(at least 1 rotten strawberry) = (92752 / 376992) + (5984 / 376992)
P(at least 1 rotten strawberry) = 0.246 + 0.016
P(at least 1 rotten strawberry) = 0.262
The probability of selecting exactly 2 rotten strawberries among n is
P(exactly 2 rotten strawberries) = [tex]\frac{(^2c_2)(^{34}c_{n-2}) }{^{36}c_n} = \frac{(^{34}c_{n-2}) }{^{36}c_n}[/tex]
The value for n is 2/35.
P(exactly 2 rotten strawberries) =[tex]\frac{(^{34}c_{\frac{-33}{35}}) }{^{36}c_{\frac{2}{35} }}[/tex]
P(exactly 2 rotten strawberries) = 1 / 1
P(exactly 2 rotten strawberries) = 1
Therefore, the probability is 0.262 and 1 strawberry must be picked.

what are the advantages of using a bar chart over a pie chart
The advantages of bar charts over pie charts while graphing the given data are discussed below.
What are the advantages of using a bar chart over a pie chart?A bar chart or bar graph is a visual representation of categorical data that uses rectangular bars with heights or lengths proportional to the values they represent. The possibility of a bar plot, both vertical and horizontal, exists. Vertical bar graphs are also referred to as column charts.
A circular statistical image known as a pie chart uses slices to represent numerical proportions. Each slice's arc length in a pie chart varies depending on the amount it represents.
Any numbers can be chosen for the numeric value axis in a bar chart.
Pie charts can only be used if the sum of the various parts equals a meaningful whole because they are intended to illustrate how each portion contributes to the whole.
Hence bar chart is more advantageous over pie chart when more information is to be presented through charts.

finding the domain of f(g(x)) (precalculus)
The domain of f(g(x)) is the set of all real numbers x for which g(x) is defined and lies in the domain of f(x).
What are the functions?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
Given f(x) = 1/(x + 1) and g(x) = 1/(x+2)
First, let's find the domain of g(x). The function g(x) = 1/(x+2), so the denominator of this fraction must be non-zero. This means that x + 2 must be non-zero, or x must not equal -2. Thus, the domain of g(x) is all real numbers except for x = -2.
Next, let's find the domain of f(x). The function f(x) = 1/(x + 1), so the denominator of this fraction must also be non-zero. This means that x + 1 must be non-zero, or x must not equal -1. Thus, the domain of f(x) is all real numbers except for x = -1.
So, for f(g(x)) to be defined, g(x) must be in the domain of f(x), or g(x) must not equal -1. Since g(x) = 1/(x+2), this means that x + 2 must not equal 0, or x must not equal -2.
Combining these two conditions, the domain of f(g(x)) is all real numbers except for x = -2 and x = -1.
Therefore, the domain of f(g(x)) is all real numbers except for x = -2 and x = -1.

The Sandwich TheoremThe Sandwich Theorem states that if f(x) < g(x) < h(x) for all x in an interval, then g must have a value that is equal to either f or h at some point in that interval.
In this case, 2x - 2 < g(x) < x^2 + 2x - 3 for all x in some interval.

Answer:
A. 1008 square inches
Step-by-step explanation:
You want the lateral area of a triangular prism with base edge lengths 10 in, 10 in, and 8 in, and a height of 36 in.
Lateral areaThe lateral area of the prism is the area of the three rectangular sides. The area of each rectangle is the product of its length and width. All have the same length, so we can sum the widths before multiplying:
LA = Pl
LA = (10 in + 10 in + 8 in)(36 in) = 28·36 in² = 1008 in²
The lateral surface area of the prism is 1008 square inches.

The general form of the equation of a hyperbola can be determined from the given information. The vertices of the hyperbola are given as (-2, 5) and (6, 5). The foci of the hyperbola are given as (-3, 5) and (7, 5). The first step in finding the equation of the hyperbola is to determine the center of the hyperbola. The center of the hyperbola can be calculated by taking the average of the x-coordinates of the vertices and then the average of the y-coordinates of the vertices. The center of the hyperbola is then (2, 5). The distance between the foci of the hyperbola is 4. This distance can be calculated by subtracting the x-coordinates of the foci and then subtracting the y-coordinates of the foci.

3
So Isaiah has a total of 6 gallons of paint and each bookcases takes 1/3 gallon. How many bookcases can he paint?
Alright to solve this problem, we can simply take the total gallons of paint Isaiah has and divide that by 1/3
So 6 divided by 1/3 should give us the answer.
But how do we divide fractions? Remember this useful tip for all throughout your school life when you don't have a calculator: Keep, Change, Flip
Keep the first fraction, change the sign to a multiplication sign, and flip the second fraction.
This should give us 6 x 3/1 or 3, which is 18.

if a is a set of real numbers which is bounded above and b is a set of real numbers which is bounded below then there is at most one real number in both a and b?
If a is a set of real numbers that is bounded above and b is a set of real numbers that is bounded below, there is at most one real number that can exist in both sets.
A real number is any number that can be expressed as a decimal or fraction and exists on the number line.
If a set of real numbers, represented by a, is bounded above, it means that there exists a real number, represented by M, such that all the numbers in the set are less than or equal to M. Similarly, if a set of real numbers, represented by b, is bounded below, it means that there exists a real number, represented by m, such that all the numbers in the set are greater than or equal to m.
Now, let's consider a real number, represented by x, that exists in both sets a and b. If x exists in a, it must be less than or equal to M and if x exists in b, it must be greater than or equal to m. Hence, x must satisfy both conditions: M >= x >= m.
From these conditions, it can be deduced that M and m must be equal to x. In other words, there can only be one real number that is simultaneously the greatest value in a and the smallest value in b.

In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the height of the building be represented as ED = H
Let the distance of mirror from the building be CD = 11.15 m
