Final answer:
The probability of independent events A, B, and C all occurring together is found by multiplying their individual probabilities: P(A AND B AND C) = P(A) × P(B) × P(C) = 0.090528.
Explanation:
The question involves calculating the probability of all three independent events happening simultaneously. To find the combined probability of independent events A, B, and C occurring at the same time, we use the multiplication rule of probability.
This rule states that if the events are independent, the probability of all events occurring is the product of their individual probabilities.
Here are the probabilities for each event:
Probability of event A (P(A)) = 0.43
Probability of event B (P(B)) = 0.32
Probability of event C (P(C)) = 0.66
The probability of events A, B, and C all occurring together is:
P(A AND B AND C) = P(A) × P(B) × P(C) = (0.43) × (0.32) × (0.66) = 0.090528

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.
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.

Circle O is shown below. The diagram is not drawn to scale.
If m∡R = 28°, what is m∡ O?
Please Explain.
Answer:
Measure of angle O is 56 degrees.
Step-by-step explanation:
We can see from diagram that NQ is minor arc and NRQ is major arc. Our angle R (inscribed angle) and O (central angle) are corresponding to minor arc NQ. We will use inscribed angle theorem which states that measure of inscribed angle is one-half the measure of central angle.
We are given that measure of inscribed angle R is 28 degrees. To find measure of our central angle O we will multiply 28 by 2.
[tex]28*2=56[/tex]
Therefore, measure of angle O will be 56 degrees.

Larry's lemons is a street vendor business that sells lemonade and lemon bars. A cup of lemonade sells for $2 and a lemon bar sells for $1.50. When all related business expenses are included, a cup of lemonade costs $0.25 to prepare and a lemon bar costs $0.20 to prepare. Last Monday, one of the vendors selling Larry's Lemons sold at least $500 worth of lemonade and lemon bars and its expenses were no more than $100. At least 150 cups of lemonade were sold. Let x be the number of cups of lemonade sold last Monday and y be the number of lemon bars sold last Monday. Which ordered pair representing a combination of cups of lemonade and lemon bars could have been sold last Monday and make sense in the context of the situation?
The one possible ordered pair that satisfies all conditions is (x, y) = (150, 134).
The ordered pair (x, y) that satisfies the following conditions:
1. The total revenue from selling x cups of lemonade and y lemon bars is at least $500. This gives us the inequality:
[tex]\[ 2x + 1.50y \geq 500 \][/tex]
2. The total expenses for preparing x cups of lemonade and y lemon bars is no more than $100. This gives us the inequality:
[tex]\[ 0.25x + 0.20y \leq 100 \][/tex]
3. At least 150 cups of lemonade were sold, which gives us the inequality:
[tex]\[ x \geq 150 \][/tex]
To find a combination of x and y that satisfies all these conditions, we can start by considering the minimum number of lemonade cups sold, which is 150. We can then calculate the revenue and expenses for this minimum number and see how many lemon bars would be needed to meet the revenue requirement while keeping the expenses within the limit.
Let's start with the minimum number of lemonade cups:
[tex]\[ x = 150 \][/tex]
The revenue from lemonade alone would be:
[tex]\[ 2 \times 150 = \$300 \][/tex]
The expenses for lemonade alone would be:
[tex]\[ 0.25 \times 150 = \$37.50 \][/tex]
Now, we need to find out how many lemon bars (y) would be needed to make up the remaining revenue to at least $500 while keeping the total expenses at or below $100.
Let's denote the remaining revenue needed as R and calculate it:
[tex]\[ R = 500 - 300 = \$200 \][/tex]
The revenue from selling y lemon bars is $1.50y, so we have:
[tex]\[ 1.50y \geq 200 \][/tex]
[tex]\[ y \geq \frac{200}{1.50} \][/tex]
[tex]\[ y \geq 133.33 \][/tex]
Since we cannot sell a fraction of a lemon bar, we round up to the nearest whole number, so at least 134 lemon bars must be sold.
Now let's check the expenses for the lemon bars. We have $100 - $37.50 = $62.50 left for expenses. The cost to prepare each lemon bar is $0.20, so we calculate the maximum number of lemon bars (y) that can be prepared with the remaining expenses:
[tex]\[ 0.20y \leq 62.50 \][/tex]
[tex]\[ y \leq \frac{62.50}{0.20} \][/tex]
[tex]\[ y \leq 312.5 \][/tex]
Combining the two conditions for y, we find that y must be at least 134 but no more than 312.
Therefore, one possible ordered pair that satisfies all conditions is (x, y) = (150, 134). This means that at least 150 cups of lemonade and at least 134 lemon bars were sold last Monday to meet the revenue and expense conditions.

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.
