How many multisets of three positive integers have a mean of 9, a median of 11 and no mode? A multiset allows multiple instances for each of its elements. For example {1,2,2} and {2,1,2} are the same multiset.
Reminders:
• The Mean is equivalent to the average.
• The Median is the middle value when values are sorted by size.
• The Mode is the most often occurring value and is not set if no value is repeated.

Answers
Answer:

Step-by-step explanation:
we are given a logarithmic expression
we want to expand it
in order to do so we can consider using
exponent logarithm propertydivision logarithm propertyrecall that,
[tex] \displaystyle \sqrt{x} = {x}^{ \frac{1}{2} } [/tex]
thus rewrite
[tex] \displaystyle \log_{ \sigma} \bigg( \frac{57}{74} \bigg) ^{ \large\frac{1}{2} } [/tex]
use division logarithm property

A basketball player makes a free throw 82.6% of the time. The player attempts 5 free throws. Use a histogram of the binomial distribution to determine what is the most likely outcome.
Answers
Answer:
The most likely outcome is exactly 4 free throws
Step-by-step explanation:
Given
[tex]n = 5[/tex] --- attempts
[tex]p = 82.6\%[/tex] ---- probability of a successful free throw
[tex]p = 0.826[/tex]
Required
A histogram to show the most likely outcome
From the question, we understand that the distribution is binomial.
This is represented as:
[tex]P(X = x) = ^nC_x * p^x * (1 - p)^{n-x}[/tex]
For x = 0 to 5, where x represents the number of free throws; we have:
[tex]P(X = x) = ^nC_x * p^x * (1 - p)^{n-x}[/tex]
[tex]P(X = 0) = ^5C_0 * 0.826^0 * (1 - 0.826)^{5-0}[/tex]
[tex]P(X = 0) = ^5C_0 * 0.826^0 * (0.174)^{5}[/tex]
[tex]P(X = 0) = 1 * 1 * 0.000159 \approx 0.0002[/tex]
[tex]P(X = 1) = ^5C_1 * 0.826^1 * (1 - 0.826)^{5-1}[/tex]
[tex]P(X = 1) = ^5C_1 * 0.826^1 * (0.174)^4[/tex]
[tex]P(X = 1) = 5 * 0.826 * 0.000917 \approx 0.0038[/tex]
[tex]P(X = 2) = ^5C_2 * 0.826^2 * (1 - 0.826)^{5-2}[/tex]
[tex]P(X = 2) = ^5C_2 * 0.826^2 * (0.174)^{3}[/tex]
[tex]P(X = 2) = 10 * 0.682 * 0.005268 \approx 0.0359[/tex]
[tex]P(X = 3) = ^5C_3 * 0.826^3 * (1 - 0.826)^{5-3}[/tex]
[tex]P(X = 3) = ^5C_3 * 0.826^3 * (0.174)^2[/tex]
[tex]P(X = 3) = 10 * 0.5636 * 0.030276 \approx 0.1706[/tex]
[tex]P(X = 4) = ^5C_4 * 0.826^4 * (1 - 0.826)^{5-4}[/tex]
[tex]P(X = 4) = 5 * 0.826^4 * (0.174)^1[/tex]
[tex]P(X = 4) = 5 * 0.4655 * 0.174 \approx 0.4050[/tex]
[tex]P(X = 5) = ^5C_5 * 0.826^5 * (1 - 0.826)^{5-5}\\[/tex]
[tex]P(X = 5) = ^5C_5 * 0.826^5 * (0.174)^0[/tex]
[tex]P(X = 5) = 1 * 0.3845 * 1 \approx 0.3845[/tex]
From the above computations, we have:
[tex]P(X = 0) \approx 0.0002[/tex]
[tex]P(X = 1) \approx 0.0038[/tex]
[tex]P(X = 2) \approx 0.0359[/tex]
[tex]P(X = 3) \approx 0.1706[/tex]
[tex]P(X = 4) \approx 0.4050[/tex]
[tex]P(X = 5) \approx 0.3845[/tex]
See attachment for histogram
From the histogram, we can see that the most likely outcome is at: x = 4
Because it has the longest vertical bar (0.4050 or 40.5%)

shirt, and 147 students did not. What
percent of the students bought a school
shirt?
Answers
Answer:
80%
Step-by-step explanation:
Step 1: Add the given data
588 + 147 = 735
Step 2: Divide the number of students who bought a school shirt by the total number of students
588 ÷ 735
= [tex]\frac{735}{588}[/tex]
= 0.8
Step 3: Convert the decimal to fraction
0.8 = 80% (Move the zero 1 place behind the number and remove the ".")
Or
0.8 × 100 = 80%
Therefore, 80% of students bought a school shirt.

Your friend tosses a ball into the air at an initial velocity of 18 feet per second. The equation h = -8t^2 + 18t + 5 models the height h of the ball t seconds after it was thrown.
1. How long was the ball in the air?
2. How high did the ball get?
3. When did the ball hit its highest point?
Answers
Answer:
2.5 s15.125 ft1.125 sStep-by-step explanation:
The time and height of the highest point represent the vertex of the graph of the height equation. The positive zero of the equation represents the time the ball was no longer in the air.
__
These points are conveniently found from the vertex form of the equation.
h = -8(t² -9/4t) +5
h = -8(t² -9/4t +81/64) +5 +8(81/64)
h = -8(t -9/8)² +15 1/8 . . . . . . . . vertex is (9/8, 15 1/8)
__
Solving for the zeros, we find ...
0 = -8(t -9/8)² +15 1/8
121/64 = (t -9/8)² . . . . . . subtract 15 1/8, divide by -8
11/8 = t -9/8 . . . . . . . take the positive square root
t = 20/8 = 2.5 . . . . the time the ball hits the ground
__
1. The ball was in the air for 2.5 seconds
2. The ball got to a height of 15 1/8 feet
3. The ball was at its highest point 1.125 seconds after it was tossed.
Explain how the distance formula can be used to find the diameter of a circle.
Answers
The distance formula can be used to find the diameter of a circle is Diameter = √(x−h)²+(y−k)².
What is distance formula?The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is Distance = √[(x₂-x₁)²+(y₂-y₁)²].
A line segment connecting two points on the circle and going through the center is called a diameter of the circle.
Use the distance formula to find the equation of the circle.
√(x₂−x₁)²+(y₂−y₁)²=d.
Substitute (x₁, y₁)=(h, k),(x₂, y₂)=(x, y) and d=r
Where, (h, k) is one point of line on circle and (x, y) is another point of line on circle which passes through the circle
Diameter = √(x−h)²+(y−k)²
Therefore, the distance formula can be used to find the diameter of a circle is Diameter = √(x−h)²+(y−k)².

A cannon ball has been catapulted through the air and follows the path created by the
function f(t) = -16t2 + 30t + 7 where f(t) is the height of the cannon ball in
meters at any given time (t) in seconds.
Answers
Answer:
the cannon ball's maximum height is 21 meters rounded to the nearest whole number
Step-by-step explanation:
The maximum height of the cannonball will be 21.06 meters when the time t = 0.9375 seconds.
What is the parabola?It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.
A cannonball has been catapulted through the air and follows the path created by the function given below.
f(t) = -16t² + 30t + 7
where f(t) is the height of the cannonball in meters at any given time (t) in seconds.
Then the height of the cannonball will be given by the differentiation. Then we have
[tex]\rm \dfrac{d}{dx} f(t) = -16t^2 + 30 t + 7 \\\\\\\dfrac{d}{dx} f(t) = -32t + 30[/tex]
Then again differentiate to check whether the value is maximum or minimum.
[tex]\rm \dfrac{d^2}{dx^2} f(t) = -32t + 30\\\\\\\dfrac{d^2}{dx^2} f(t) = -32\\\\\\\dfrac{d^2}{dx^2} f(t) < 0[/tex]
Then the value of the height will be maximum for f'(t) = 0.
f'(t) = 0
-32t + 30 = 0
t = 30/32
t = 0.9375
Then the maximum height will be
f(t) = -16(0.9375)² + 30(0.9375) + 7
f(t) = -14.0625 + 28.125 + 7
f(t) = 21.0625
f(t) = 21.06 meters
