Answer:
The median is 46
Step-by-step explanation:
To find the median, you must first order the numbers, from left to right, lowest to highest:
24, 27, 29, 38, 54, 61, 68, 74
Next, we have to find the number in the middle. We can do this by counting inwards one and crossing out each of the lowest and highest each time we get closer to the middle/center.
24, 27, 29, 38, 54, 61, 68, 74
, 27, 29, 38, 54, 61, 68,
, , 29, 38, 54, 61, ,
, , , 38, 54, , ,
Now, if there is no exact middle, we would add them add divide by 2. If there was an exact middle, that would be the answer. But there isn't.
38 + 54 = 92
92 / 2 = 46
The median is 46

What is the radius of a circle whose equation is x2 y2 8x−6y 21=0? 2 units 3 units 4 units 5 units
The center of the circle x² + y² + 8x − 6y + 21 = 0 is at (-4, 3) and the radius of the circle is 2 units.
What is a circle?It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The equation of the circle is given as
x² + y² + 8x − 6y + 21 = 0
The equation can be written as
x² + 8x + 16 + y² − 6y 9 = 4
(x + 4)² + (y − 3)² = 2²
Then the center of the circle is at (-4, 3) and the radius of the circle is 2 units.

The speed that a tsunami can travel is modeled by the equation s = 356 startroot d endroot , where s is the speed in kilometers per hour and d is the average depth of the water in kilometers. what is the approximate depth of water for a tsunami traveling at 200 kilometers per hour? 0.32 km 0.75 km 1.12 km 3.17 km
The approximate depth of water for a tsunami traveling at 200 kilometers per hour is 0.32 km.
What is speed?Speed can be calculated as the ratio of distance traveled to the time taken.
The speed that a tsunami can travel is modeled by the equation
s = 356√d, where s is the speed in kilometers per hour and d is the average depth of the water in kilometers.
S = 356√d
200 = 356√d
√d = 200/356
= 0.5618
d = 0.5618^2
= 0.316 km
d = 0.32 km.
Thus, The approximate depth of water for a tsunami traveling at 200 kilometers per hour is 0.32 km.

To find inverse, make x the subject
[tex]\rightarrow \sf f(x)+9 = 2x[/tex]

A company sells kayaks for $575. Each kayak costs them $480 to manufacture. Write a linear function that represents the profit generated from selling the manufactured kayaks.
A linear function that represents the profit generated from selling the manufactured kayaks is P(x) = $575x - $480x.
What is the linear function that represents profit?
Profit is the total selling price of an item less the cost price.
Profit = selling price - cost price.
A linear function is a function that has a single variable raised to the power of 1. An example is x + 2 The variable x is raised to the power of 1. 2 is the constant terms.
P(x) = $575x - $480x.
Where x represents the number of manufactured kayaks sold

Answer:
15/20 in simplest form is 3/4
Step-by-step explanation:
15/20 in simplest form is 3/4 cause if you divide 15 by 5 you get 3 and if you divide 20 by 5 you get 4
The simplest form of the given fraction 15/20 is 3/4.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Given that, Kenisha's dog ate 15/20 of a bag of dog food last week.
The simplest form is the smallest possible equivalent fraction of the number.
Here, simplest form of 15/20
Divide both the numerator and denominator by 5, we get
15÷5/20÷5 = 3/4
Therefore, the simplest form of the fraction is 3/4.

What is the chain rule in probability for two events?For two events A and B:

How to form two-way table?Suppose two dimensions are there, viz X and Y. Some values of X are there as [tex]X_1, X_2, ... , X_n[/tex] and some values of Y are there as [tex]Y_1, Y_2, ... , Y_n[/tex]
List them in title of the rows and left to the columns. There will be n \times k table of values will be formed(excluding titles and totals), such that:
Value(ith row, jth column) = Frequency for intersection of [tex]X_i[/tex] and [tex]Y_j[/tex] (assuming X values are going in rows, and Y values are listed in columns).
Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.
For n = 2, and k = 2, the table would look like:
[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]
where S denotes total of totals, also called total frequency.
n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.
The missing two-way table for this problem is given below:
[tex]\begin{array}{cccccc}&A&B&AB&O&\rm Total\\\text{Negative}&0.07&0.02&0.01&0.08&0.18\\\text{Positive}{&0.33&0.09&0.03&0.37&0.82\\\rm Total & 0.40&0.11&0.04&0.45&1 \end{array}[/tex]
Instead of frequencies, it contains ratio of frequency to total count of people surveyed (thus, relative frequency).
We want the probability that a person has a positive rh factor given that he/she has type O blood.
If we take:
E = event that a random person chosen has a positive rh factor
and F = event that a random person chosen has type O blood
Then, the needed probability is written symbolically as:
P(E|F).
Using the considered two-way table and the chain rule, we get this probability as:
[tex]P(E|F) = \dfrac{P(E \cap F)}{P(F)} = \dfrac{n(E \cap F)/ n(Total)}{n(F)/n(Total)}[/tex]
Since the two way table consists relative frequency with total count, so, we get:
[tex]n(E \cap F)/n(Total) = 0.37\\n(F)/n(Total) = 0.45[/tex]
[tex]P(E|F) = \dfrac{n(E \cap F)/ n(Total)}{n(F)/n(Total)} = \dfrac{0.37}{0.45} \approx 0.822 = 82.2\%[/tex]
Thus, the probability that a person has a positive rh factor given that he/she has type O blood is approximately 82.2 %
