The experimental probability of an odd number other than 9 being generated is 38%.
Explain the term experimental probability?A probability that has been established by a series of tests is called an experimental probability. To ascertain their possibility, a random experiment is initiated and iterated over a number of times; each iteration is referred to as a trial. The goal of the experiment is to predict the likelihood that an event will occur or not.For the stated question-
150 numbers altogether.Odd numbers in total: 72There are 15 nines.Other odd numbers outside nine are as follows: 72 - 15 = 57
Probability = (number of odd numbers except nine)]/(total number)
Probability = 57/150
Probability = 0.38.
Thus, the experimental probability of an odd number other than 9 being generated is 38%.

In winter, apple prices suddenly increase by €0.75 per kilogram. Sam bought 3 kilograms of apples for the new price of €5.88.
Answer:
p represents the original per pound price
3p represents the cost of three pounds
3p + 3(0.75) = 5.88 multiply
3p + 2.25 = 5.88 subtract 2.55 from both sides
3p = 3.63 divide both sidesby 3
p = 1.21
The original price was $1.21 per pound.
1.21 = 0.75

The probability that one of the first five customers agrees to take the survey is 71%
Here we have to use binomial distribution.
What is binomial distribution?
A common probability distribution known as the binomial distribution simulates the likelihood of getting one of two outcomes given a set of parameters. It provides a summary of the number of trials when each trial has an equal chance of producing a particular result.
A binomial distribution with the following formula could be used to represent the proportion of clients who agree to participate in the survey out of 5:
X ~ Bin (n = 5, p = 0.22)
Thus the probability is computed as:
P(X >= 1) = 1 - P(X = 0) = [tex]1 - (1-0.22)^5[/tex]
= 0.71
The required probability in this case is therefore 71%.

An employee at a paint manufacturing plant is mixing highly pigmented paint with some paint that is less pigmented. In addition to a large supply of 27%-pigment paint, he also has 160 liters of 12%-pigment paint. How many liters of the 27%-pigment paint should he add to the 12%-pigment paint to generate a batch of 15%-pigment paint?.
With the help of unitary method , we can say that ,To create a batch of 15%-pigment paint, he needs to mix 98.57 liters of the 27%-pigment paint with the 12%-pigment paint.
What is unitary method ?Area is the total amount of space that an object's shape or a flat (2-D) surface occupy.
Create a square on paper by using a pencil. Two dimensions make it up. A shape's area on paper is the space it takes up.
Imagine that your square is made up of smaller unit squares.
The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.
To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured.
According to our question-
Paint volume times pigment concentration equals pigment amount.
or
V × c = P
If the three options are referred to as 1, 2, and 3, then
P₁ + P₂ = P₃
V1c1 = V2c2 + V3c3
Let x equal the paint's 11% volume.
Then
230 × 21 % + x × 11 % = (230 +x) × 18 %
Add 4830 plus 11x to get 4140 plus 18x, then take 4140 away from each side.
690 + 11x = 18x Take 11 times off of each side.
Divide each side of 690 by 7 to get the answer.
x = 98.57 L
The worker needs to add 98.57 L of the paint with a 21% pigment.

What characteristics do related triangles share?When the ratio of two triangles' respective sides is equal in magnitude while their corresponding angles are congruent, two triangles are said to be comparable in geometry.Furthermore, two geometric forms are only regarded as congruent when their associated side lengths and angle magnitudes are congruent.We can now create an equation which can be used to calculate the height of the tree.Part a: Height of the tree;
We get the following mathematical formula (equation) since the ratio of a corresponding sides of similar triangles is equal in magnitude:
22.5/8.25 = x/5.5
In which
x is the height of the tree.
Then,
22.5/8.25 = x/5.5
Further simplifying;
8.25x = 22.5 × 5.5
8.25x = 123.75
x = 123.75/8.25
x = 15 feet. (height of the tree)
Part b: distance of tree from person;
These calculations can be used to determine how far away from the tree this individual is:
Distance equals the product of a person's shadow and a tree's shadow
Distance = 22.5 - 8.25
Distance = 14.25 feet.

Show your work and explain your reasoning.
Answer:To help read it step by step until you understand trust me you will get it!
Step-by-step explanation:
The total volume of the ice cream in and on top of the cone is (16/3)πd³.
What is a cone?It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.
The volume of a cone is 1/3 πr²h.
We have,
Volume of the hemisphere = 4 in³
The volume of ice cream.
= Volume of the hemisphere + Volume of the cone
= 4 + (1/3)π(d/2)²h
[ height = diameter ]
= 4 + (1/3) x π x d²/4 x d
= 4 + (1/3) x π x d³/4
= 4 + (4/3)πd³

out of 240 racers who started the marathon, 209 completed the race, 22 gave up, and 9 were disqualified. what percentage did not complete the marathon?
The percentage of racers that did not complete the marathon is 12.9 %
What is arithmetic?
Arithmetic is an elementary a part of mathematics that consists of the study of the properties of the normal operations on numbers—addition, subtraction, multiplication, division, involution, and extraction of roots
Main Body:
Total racers = 240
racers that completed race = 209
so racers that did not complete the marathon = 240 - 209
= 31
percentage of racers that did not complete the marathon = (31/240)*100
= 12.9 %
Hence percentage of racers that did not complete the marathon is 12.9%

a farmer wants to fence an area of 3750 square feet in a rectangular field and then divide it in half with a fence parallel to one of the sides of the rectangle. what should the lengths of the sides of the rectangular field be so as to minimize the amount of fencing needed?
The lengths of the sides of the rectangular field so as to minimize the amount of fencing needed is 30 feet by 20 feet
Let x represent the length of the fence and y represent the width of the fence.
Since the area is 3750, hence:
Area = length * width = x * y
3750 = xy
y = 3750/x
A fence divide the field in half and is parallel to one of the sides of the rectangle. Hence:
Amount of fencing needed (P) = x + x + y + y + y = 2x + 3y
Amount of fencing needed (P) = 2x + 3(3750/x) = 2x + 1800/x
To minimize the amount of fencing needed, dP/dx = 0, hence:
dP/dx = 2 - 1800/x²
2 - 1800/x² = 0
2 = 1800/x²
2x² = 1800
x² = 900
x = 30 feet
y = 600/x = 600/30 = 20 feet
Hence, the lengths of the sides of the rectangular field so as to minimize the amount of fencing needed is 30 feet by 20 feet

In a coordinate plane, a line has two points A and B with the coordinates A(4,n) and B(10,6n). In the same coordinate plane, a different line has two points C and D with coordinates C(−3,−6) and D(9,8n). For what value of n are the two lines parallel?
For the two lines to be parallel, the value of n must be 3
How are two lines parallel in a coordinate?When two straight lines are plotted on the coordinate plane, we can tell if they are parallel from the slope, of each line. If the slopes are the same then the lines are parallel.
The slope of each line is calculated as (y2-y1)/x2-x1
for line AB, the slope = (6n-n)/10-4 = 5n/6
for line CD, the slope= 8n-(-6)/9-(-3)=( 8n+6)/12
for AB and CD to be parallel,
5n/6 = (8n+6)/12
multiply both sides by 12
10n= 8n+6

the sum of the height and radius of a right cylinder is 12 inches. what is the maximum volume of this cylinder
The maximum volume of this cylinder = 256π cubic inches
What is volume?
In three-dimensional space, volume is the area occupied by an object within its borders. Another name for it is an object's capacity.
Let h be the height and r be the radius.
Then, h+r = 12
=> h=12-r
Volume of the cylinder (V):
V=πr²h
=> h= πr² ( 12-r )
=> h= π ( 12r² - r³ )
Differentiate with respect to r , we get
dv/dr = 24 πr - 3πr²
Find r by taking dv/dr=0
24 πr - 3πr² = 0
3π ( 8r - r² ) = 0
8r = r²
r=8
Again differentiating, we get
d²V/dr² = 24π - 6 π r
When r=8, 24π - 48 π <0
So, V is maximum at r= 8 inches
And h= 12-8= 4 inches
Hence, the required volume of the cylinder = π8²*4 = 256π cubic inches
