The experimental probability of winning a free gallon of milk will be calculated as under -
It is given that, total number of outcomes = 156
Non-winning customers = 147 (it is given in the question)
Thus, the winning customers will be = Total outcomes - Non-winning customers
Expected winning customers = 156 - 147 = 9
The probability is calculated as -
Probability (Winning customer) = [tex] \frac{Winning Customers}{Total Customers} [/tex]
Probability (Winning customer) = [tex] \frac{9}{156} [/tex] = [tex] \frac{3}{52} [/tex]

Lincoln Technical College has 856 students. They expect 700 guests for a special speaker. The custodian has set up 1,500 chairs. How many more chairs are needed if everyone is to have a seat? 3. Draw a picture or a chart that shows the information and the question
57 chairs are needed if everyone is to have a seat
To calculate the number of additional chairs needed, we first need to determine the total number of seats required. This is the sum of the students, guests, and speaker. Then, we subtract the number of chairs already set up to find out the additional chairs needed.
Let's break it down step by step:
1. Total number of seats required:
- Students: 856
- Guests: 700
- Speaker: 1 (assuming the speaker needs a seat)
Total seats required = 856 (students) + 700 (guests) + 1 (speaker) = 1,557 seats
2. Number of chairs already set up: 1,500
3. Additional chairs needed:
Total seats required - Chairs already set up = 1,557 - 1,500 = 57
So, Lincoln Technical College needs 57 more chairs to accommodate everyone if all students, guests, and the speaker are to have a seat.
Lincoln Technical College has 856 students and expects 700 guests for a special speaker, making the total number of attendees 1,557. The custodian has already set up 1,500 chairs. To find out how many more chairs are needed, we subtract the number of chairs already set up from the total seats required. This calculation reveals that 57 additional chairs are needed to ensure that everyone has a seat. It's essential to consider all attendees, including students, guests, and the speaker, to accurately determine the total seating requirements.
Complete question:
Lincoln Technical College has 856 students. They expect 700 guests for a special speaker. The custodian has set up 1,500 chairs. How many more chairs are needed if everyone is to have a seat?

A. (2x + 3)(x + 1)
B. (x + 3)(x + 3)
C. (x + 3)(x + 1)
D. (2x + 3)(x + 3)
Answer:
Factorization of 2x²+5x+3 is:
A. (2x + 3)(x + 1)
Step-by-step explanation:
We have to factorize the expression:
2x²+5x+3
We will solve this expression by splitting the middle term method
2x²+5x+3
=2x²+2x+3x+3
=2x(x+1)+3(x+1)
=(2x+3)(x+1)
Hence, factorization of 2x²+5x+3 is:

2,400 principal earning 2%, compounded annually, after 7 years. Find the balance in the account
The balance in the account after 7 years will be approximately $2,747.70.
How did we get the value?To calculate the balance in the account after 7 years with a principal of $2,400 earning 2% interest compounded annually, you can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the future balance
P = the principal amount ($2,400)
r = the annual interest rate (2% or 0.02 as a decimal)
n = the number of times the interest is compounded per year (annually, so n = 1)
t = the number of years (7 years)
Plug these values into the formula:
A = 2400(1 + 0.02/1)^(1*7)
A = 2400(1 + 0.02)⁷
A = 2400(1.02)⁷
A = 2400(1.144877)
A ≈ $2,747.70
So, the balance in the account after 7 years will be approximately $2,747.70.

The flower garden has the shape of a right triangle. 68 ft of a perennial border forms the hypotenuse of the triangle, and one leg is 28 ft longer than other leg. find the lengths of the legs.
The shorter leg of the triangle is 32 feet long.
The longer leg of the triangle is 60 feet long.
In this case, we are given that the hypotenuse of the triangle is 68 feet, and one leg is 28 feet longer than the other leg. Let's call the length of the shorter leg "x". Then, the length of the longer leg is "x + 28".
Using the Pythagorean theorem, we can write the following equation:
68^2 = x² + (x + 28)²
Simplifying this equation, we get:
4624 = 2x² + 56x + 784
Solving for x, we find that:
x = 32 or x = -60
Since the length of a side of a triangle cannot be negative, we reject the solution x = -60. Therefore, the length of the shorter leg is 32 feet, and the length of the longer leg is 32 + 28 = 60 feet.

Find the total area of the regular pyramid.
Answer:
Area of the regular pyramid = 16.64 square units.
Step-by-step explanation:
Given : Regular pyramid .
To find: Find the total area of the regular pyramid.
Solution : We have given that regular pyramid.
Area = 4 ( area of triangle ) + area of base .
Area of the regular pyramid = 4 ( [tex]\frac{1}{2} * base * height + side * side[/tex].
Area of the regular pyramid = [tex]4(\frac{1}{2}* 2* \sqrt{10} + 2*2[/tex]
Area of the regular pyramid = [tex]4( \sqrt{10} ) + 4[/tex]
Area of the regular pyramid = (4 [tex]( \sqrt{10} ) \+\ 1[/tex].
Area of the regular pyramid = 16.64 square units.
Therefore, Area of the regular pyramid = 16.64 square units.

From the graph we can conclude that it is a sine or cosine function. In their standard form, these functions are given by the following equations:
[tex]y(t)=Acos(\omega t +\phi)\\\\or\\\\y(t)=Asin(\omega t+ \phi)[/tex]
Where:
[tex]A=Amplitude=\frac{|A_m_i_n-A_m_a_x|}{2}\\\omega=Angular\hspace{3}frequency\\\phi=Initial \hspace{3}phase[/tex]
And:
[tex]A_m_a_x=Maximum\hspace{3}amplitude\\A_m_i_n=Minimum\hspace{3}amplitude[/tex]
On the other hand, we can define the midline of these kind of functions as the halfway between the maximum and minimum amplitude of the function, Therefore:
[tex]Midline=M_l=\frac{A_m_a_x+A_m_i_n}{2}[/tex]
From the graph you can see that the maximum value of the function(maximum amplitude) is 2 and the minimum value of the function (minimum amplitude) is 0, thus:
[tex]A=\frac{|A_m_i_n-A_m_a_x|}{2} =\frac{|0-2|}{2} =\frac{|-2|}{2} =\frac{2}{2} =1[/tex]
And:
[tex]M_l=\frac{A_m_a_x+A_m_i_n}{2}=\frac{2+0}{2} =\frac{2}{2} =1[/tex]
