in an experiment, what is the probability than even A occurs is 0.2 and the probability that event b occurs is 0.5
Answers
Answer: In an experiment, if the probability that event A occurs is 0.2 and the probability that event B occurs is 0.5, then the probability that either event A or event B (or both) will occur is the sum of their individual probabilities, which is 0.2 + 0.5 = 0.7.
It should be noted that the sum of the individual probabilities of two events is less than or equal to 1. If the sum of the probabilities is greater than 1, it means that the events are not mutually exclusive and that means that they can happen at the same time.
It's important to mention that the above answer is based on the assumption that events A and B are mutually exclusive events, which means that they cannot happen at the same time. If they are not mutually exclusive, the probability of both occurring at the same time would have to be calculated using the formula P(A and B) = P(A) * P(B|A) where P(A) is the probability of event A occurring and P(B|A) is the probability of event B occurring given that event A has already occurred.

Use the Distributive Property to rewrite each algebraic expression
15(2 + r)
Answers
The algebraic expression 15(2 + r) by the distributive property can be written as 30 + 15r.
What is distributive property?This property states that multiplying the sum of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the algebraic expression is 15(2 + r). The expression by using the distributive property can be written as:-
E = 15(2 + r)

What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given that ΔXYZ, y = 500 inches, mm∠Y=117° and mm∠Z=10°.
We have to find the length of z.
By using sine rule we find the length of z.
sin117/500=sin10/z
0.891/500=0.174/z
Apply cross multiplication
0.891z=0.174×500
0.891z=87
z=87/0.891
z=97.64 inches
Hence, if in ΔXYZ, y = 500 inches, mm∠Y=117° and mm∠Z=10° then length of z is 97.64 inches.

we determined median = 140 and lower quartile = 105.
What is median and quartile in a statistics data?Median is the middle value of a set of data. Median is determined by the formula, median = 2/4 (N+1)th term, where N is the number of data set.
Quartile is a statistics terms defines that a list of data is divided into four parts. There are three quartiles in the statistics data such as lower quartile, middle quartile and upper quartile.
lower quartile = 1/4(N+1)th term
upper quartile = 3/4(N+1)th term
the median is called the middle quartile.
What is the median and lower quartile for the above histogram?From the histogram we obtain the data below
80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200
number of data, N = 13
median = 2/4 (N+1)th term= 1/2 ×14 = 7th term
we find 7th term is 140.
median = 140
lower quartile= 1/4× (N+1)th = 1/4 × 14 = 3.5 th term
that means average of 3 and 4th term.

Evaluate the iterated integral. 1 0 s5 cos(s6) dt ds 0
Answers
The value of the evaluated iterated integral is = 0.002
As per the given data the iterated integral is, [tex]I[/tex] = [tex]\int\limits^1_0[/tex] [tex]\int\limits^s_0[/tex] cos ([tex]s^{6}[/tex] ) [tex]dt ds[/tex]
Here we have to evaluate the given iterated integral.
The definite integral of a real-valued function f(x) with respect to a real variable x on an interval [a, b] is expressed as,
[tex]\int\limits^a_b f({x} )\, dx[/tex] = f(b) - f(a)
Where,
a = Lower limit
b = Upper limit
f(x) = Integrand
dx = Integrating agent
Thus, [tex]\int\limits^_[/tex] ab f(x) dx is read as the definite integral of f(x) with respect to d x from a to b.
Indefinite integrals are implemented when the boundaries of the integrand are not specified.
[tex]I[/tex] = [tex]\int\limits^1_0[/tex] [tex]\int\limits^s_0[/tex] cos ([tex]s^{6}[/tex] ) [tex]dt ds[/tex]
Integrate the given iterated integral.
We get:
= [tex]\int\limits^1_0[/tex] cos ([tex]s^{6}[/tex] ) ([tex]\int\limits^5_0dt[/tex] ) ds
= [tex]\int\limits^1_0[/tex] cos ([tex]s^{6}[/tex] ) [t][tex]0 to s^{5}[/tex] ds
= [tex]\int\limits^1_0[/tex] cos ([tex]s^{6}[/tex] ) [tex](s^{5} -0)[/tex] ds
= [tex]\int\limits^1_0[/tex] [tex]s^{5}[/tex]cos ([tex]s^{6}[/tex] )ds
Then,
[tex]s^{6}[/tex] = t when s = 0
[tex]\frac{dt}{ds}[/tex] = 6[tex]s^{5}[/tex] t = 0
[tex]\frac{dt}{6}[/tex] = [tex]s^{5}[/tex] ds when s = 1..... t = 1
Replace the assumed terms.
Then we get:
[tex]I[/tex] = [tex]\int\limits^1_0[/tex] cos(t) [tex]\frac{dt}{6}[/tex]
[tex]I[/tex] = [tex]\frac{1}{6}[/tex] [tex]\int\limits^1_0[/tex] cos(t) dt
[tex]I[/tex] = [tex]\frac{1}{6}[/tex] [sin(t)][tex]0to1[/tex]
[tex]I[/tex] = [tex]\frac{1}{6}[/tex] [ sin(1) - sin(0) ]
[tex]I[/tex] = [tex]\frac{sin(1)}{6}[/tex]
[tex]I[/tex] = 0.002

If the graph of a distribution of data shows that the graph is symmetric then the:
a) Midrange is a better measure of central tendency
b) Mean is a better measure of central tendency
c) Mode is a better measure of central tendency
d) Median is a better measure of central tendency
Answers
The correct option is:
d) Median is a better measure of central tendency
When a graph of a distribution of data is symmetric, it means that the left and right sides of the graph are mirror images of each other. This indicates that the data is evenly distributed around the center and that there are no extreme outliers. In such cases, the median is the best measure of central tendency, because it is the middle value of the dataset and it represents the center of the data distribution. The median is not affected by outliers.
The mean, mode, and midrange are also measures of central tendency, but they may not be as representative of the center of the data distribution when the data is symmetric. The mean is sensitive to outliers, the mode is the value that appears most frequently in the data, and the midrange is the average of the maximum and minimum values.

what is interest ?By dividing the principal by the interest rate, the passage of time, and other factors, simple interest is determined. Simple return equals principal plus interest plus hours is the formula used in marketing. The easiest way to compute interest is by using this method. The most typical method for calculating interest is as a portion of the principal amount. For example, if he borrows $100 from a buddy and agrees to pay back the loan at 5% interest, he will only pay his share of the 100% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and you must charge interest when you lend it. Typically, interest is determined as an annual percentage of the loan total. The loan's interest is the name given to this percentage.

Write two equations showing the Transitive Property of Equality. Justify your reasoning.
Answers
x + 5 = 9 and 9 = y - 2
x + 5 = y - 2
a^2 + 2ab + b^2 = (a+b)^2 and (a+b)^2 = a^2 + 2ab + b^2
a^2 + 2ab + b^2 = a^2 + 2ab + b^2
In both examples, by using the transitive property, we can conclude that x = y and (a+b)^2 = (a+b)^2 which both are same expressions.
In the first equation, we start with x + 5 = 9 and then 9 = y - 2. Since both sides of the first equation are equal to 9, we can substitute 9 for x + 5 in the second equation, giving us 9 = y - 2. This shows that the left side of the first equation is equal to the right side of the second equation, which is the Transitive Property of Equality.
In the second equation, we start with a^2 + 2ab + b^2 = (a+b)^2 and then (a+b)^2 = a^2 + 2ab + b^2, since both sides are the same then we can substitute (a+b)^2 for a^2 + 2ab + b^2 in the second equation, which results in (a+b)^2 = (a+b)^2. This shows that the left side of the first equation is equal to the right side of the second equation, which is the Transitive Property of Equality.
In summary, The transitive property states that if you have two expressions are equal to each other, and the second expression is equal to the third, then the first and the third expressions are equal to each other.

Answers
14) Probability that exactly 5 of the students will graduate is 0.1636.
15) Probability that atleast 8 of the students will graduate is 0.2405.
We have , In a college,
The freshmen graduate enters = 64%
Probability of sucess , p = 64% = 0.64
Probability of failure , q = 1 - 0.64 = 0.36
Randomly selected entering = 10 , i.e, n = 10.
This follows a Binomial probability distribution with the parameters, n = 10 and p = 0.64.
Using Binomial probability formula,
P(X = x) = ⁿCₖ pᵏ (1 - p)ⁿ⁻ᵏ
(14) Probability that exactly 5 of the students will graduate = P(x = 5),
P( x = 5) = ¹⁰C ₅ (0.64⁵) (0.36⁵)
