What is the median for the following scores for Mr.smiths first test? 55,42,78,99,69,83,74,83,97
Answers
Answer:
78
Step-by-step explanation:
The median of a set is the middle number.
First, we have to put the numbers into numerical order.
42, 55, 69, 74, 78, 83, 83, 97, 99
Then, count the number of numbers, which is 9
Then, the middle of 9 is 5, because:
1, 2, 3, 4, 5, 6, 7, 8, 9
There are four numbers on either side of 5.
Lastly, find the 5th number in the set.
It is 78. So, the median of the set is 78.
Answer:
78
Step-by-step explanation:
to know the median you should first order the numbers from the smallest to the largest. that is
42,55,69,74,78,83,83,97,99
you take the number in the middle or if the number found in the middle are 2 then you add them up and divide them by 2 because they are 2. so in this case the number is only one which is 78 so that is the median.

A circle has a diameter of 8 inches. What is the area of this circle? Use 3.14 for pi.
(100 POINTS I NEED THE ANSWER SO I PASS THIS YEAR)
Answers
Given that a circle has a diameter of 8 inches and we are required to find its area using 3.14 as pi.
We know that the formula for calculating the area of a circle is A = πr², where A is the area, π is the mathematical constant pi (approximately 3.14), and r is the radius of the circle.
Since we are given the diameter of the circle, we can calculate its radius using the formula: radius (r) = diameter/2
Therefore, the radius of this circle is: r = 8/2 = 4 inches
Now, we can calculate the area of the circle using the formula: A = πr² Substituting the value of r, we get: A = 3.14 x 4² A = 3.14 x 16 A = 50.24 square inches
Therefore, the area of the circle is 50.24 square inches.
The answer is:
50.24 in²Work/explanation:
The formula for the circle's area :
\(\sf{A=\pi r^2}\)
where :
A = areaπ = 3.14r = radiusWe know the diameter, but the radius is one-half of that, so the radius is :
Radius = Diameter ÷ 2 = 8 ÷ 2 = 4 inchesHere's a diagram for better understanding:
\(\setlength{\unitlength}{1.1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\small 4\ in}\end{picture}\)
Now, plug in the data:
\(\large\begin{gathered}\bf{A=\pi r^2}\\\\\bf{A=3.14\times4^2}\\\\\bf{A=3.14\times16}\\\\\bf{A=50.24\:in^2}\end{gathered}\)
Therefore, the area is 50.24 in².I'm confused can someone help me!

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
Three research departments have 8 ,10 , and 7 members, respectively. Each department is to select a delegate and an alternate to represent the department at a conference. In how many ways can this be done?
Answers
We can conclude that exists 211680 ways.
How many ways can this be done?We know that the three research department is have 8, 10, and 7 members.
We choose a delegate and an alternate to represent the department.
First case: department have 8 members.
So, for a delegate, we have 8 options, and for a alternate 7, so a total of
\(8 \times 7 = 56 \ \text{options}\)
Second case: department have 10 members.
So, for a delegate, we have 10 options, and for a alternate 9, so a total of
\(10\times 9 =90 \ \text{options}\)
Third case: department have 7 members.
So, for a delegate, we have 7 options, and for a alternate 6, so a total of
\(7\times6 = 42 \ \text{options}\)
Therefore, we get:
\(56 \times 90 \times 42 = \bold{211680}\)
Hence, we conclude that exists 211680 ways.
For a similar problem about this, please click the link below:
https://brainly.com/question/30958797
For the first department with 8 members, there are 8 choices for selecting a delegate. After choosing a delegate, there remain 7 members, so there are 7 choices for selecting an alternate. Therefore, there are 8 × 7 = 56 ways to select a delegate and an alternate from the first department.
Similarly, for the second department with 10 members, there are 10 choices for selecting a delegate and 9 choices for selecting an alternate. Hence, there are 10 × 9 = 90 ways to select a delegate and an alternate from the second department.
For the third department with 7 members, there are 7 choices for selecting a delegate and 6 choices for selecting an alternate. Thus, there are 7 × 6 = 42 ways to select a delegate and an alternate from the third department.
To find the total number of ways to select delegates and alternates from all three departments, we multiply the number of choices for each department together:
56 × 90 × 42 = 211,680.
Therefore, there are 211,680 ways to select a delegate and an alternate from each department.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

(d) x = -3/4; y = -3 1/2
Step-by-step explanation:
You are asked for the coordinates of the point of intersection of the lines on the graph. This requires interpolation, because not all grid lines are marked, and the point is not on any grid line.
InterpolationThe idea of "interpolation" is figuring the value of a point that lies between points whose values are known. The answer choices here suggest that we are to interpolate to the nearest 1/4 unit. This requires that you mentally (or actually) divide the space between grid lines into 4 equal sections, and figure where the point lies relative to those divisions.
In the case of the x-coordinate, the first grid line left of the y-axis is not marked, but we notice it lies halfway between x=0 and x=-2. That means we can safely assume that the unmarked vertical grid line has a value of x=-1.
Applicationhorizontal coordinate
The location of the point of intersection of the two lines is horizontally closer to the -1 (unmarked) grid line than it is to the y-axis. Its x-value will be between -1 and 0. The answer choices tell us it is -3/4, consistent with it being about 3/4 of the distance toward -1 from 0.
x = -3/4
vertical coordinate
The location of the point of intersection of the two lines is vertically about halfway between -3 and -4. The answer choices tell us it is -3 1/2.
y = -3 1/2
