The total area of the three triangles is
square units.
The area of the figure is
square units.
The total area of the three triangles is square units is 36 and the area of the figure is square units is 60.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
From the figure, the area of triangles can be calculated using the:
Area = (1/2)height×base length
Area of three triangle = 1/2(4×6) + 1/2(6×4) + 1/2(4×6)
Area of three triangle = 1/2(24×3) = 36 square units
Area of the figure = area of three triangle + area of the rectangle
= 36 + 6×4
= 60 square units
Thus, the total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

15 people working 5 hourse per day can make 30 units of a product in 10 days. Assuming all other factors remaining constant and people of same efficiency are used to make the same products, in how many days can 10 people make 10 units of the product if each of them works 10 hours per day?
- 2.5 days
- 7.5 days
- 12 days
- 26 days
Answer:
2.5 days
Step-by-step explanation:
To solve this problem, we can use the concept of work rate. The work rate is defined as the amount of work done per unit of time.
Given:
15 people working 5 hours per day can make 30 units of the product in 10 days.
From this information, we can calculate the work rate of these 15 people:
Work rate = Total units of the product / (Number of people × Number of hours × Number of days)
Work rate = 30 units / (15 people × 5 hours × 10 days)
Work rate = 0.04 units per person per hour
Now, we need to find how many days it will take for 10 people, working 10 hours per day, to make 10 units of the product.
Using the work rate formula:
Number of days = Total units of the product / (Number of people × Number of hours × Work rate)
Number of days = 10 units / (10 people × 10 hours × 0.04 units per person per hour)
Number of days = 2.5 days
Therefore, 10 people, working 10 hours per day, can make 10 units of the product in 2.5 days.
The correct answer is:
2.5 days
you and a friend have created a carnival game for your classmates. you plan to charge $1 for each time a student plays, and the payout for a win is $5. according to your calculations, the probability of a win is .05 what is your expected value for this game?
Answer:
The expected value for this game is -$0.75, indicating that, on average, players would expect to lose $0.75 per game.
Step-by-step explanation:
Expected Value = (Probability of Winning * Payout for Win) - Cost of Playing
In this case:
Probability of Winning = 0.05
Payout for Win = $5
Cost of Playing = $1
Expected Value = (0.05 * $5) - $1
Expected Value = $0.25 - $1
Expected Value = -$0.75

TRUE/FALSE. like the edges of a filled-in area, the endpoints of a polygon do not need to conform to snap points.
False is the statement, "Polygon endpoints need not conform to snap points, like the boundaries of a filled-in region."
The surface's perimeter is defined by the edge of a filled-in area. An area is a two-dimensional space that any surface can cover. Typically, the edges of the space serve as the surface's boundary. To create a closed area or surface, the edges or the boundary must link.
Similar to end points, snap points are the ends of a polygon's sides. A closed figure can only be formed when these endpoints are connected. A closed polygon is one that has n sides.

Answer:
The relation (13,14), (13,5). (16,7). (18,13) is not considered a function
Step-by-step explanation:
Relations are only considered functions if each x value, which is the first number in each ordered pair or set of parentheses, has only one corresponding y-value, which is the second number in each ordered pair. The third option has two y-values, 14 and 5, for one x-value, 13. This means that it does not satisfy the requirements to be a function and therefore it is not a function.

Answer:

H1 : service subscription and age are not independent
Observed values :

Expected Values:

The Chisquare values :
4.15172__ 5.7569__ 10.8438
6.74518_ 9.35307 __ 17.6176
χ² = 4.15172 + 5.7569 + 10.8438 + 6.74518 + 9.35307 + 17.6176 = 54.46827
Degree of freedom = (row-1)*(column-1) = (2-1)*(3-1) = 1*2 = 2
Pvalue at df = 2 ; Pvalue = 0
α = 0.05
Pvalue < Α ; Hence, we reject H0 ; and conclude that service subscription and age are not independent
10. Prime numbers from 1 to 100 are running a restaurant - PRIME SPOT, near a tourist point. On a winter holiday, 1 and the composite numbers up to 100 enter the restaurant for dinner after their picnic at the same point. The dining hall has tables with seating capacity 15 for each. If they occupy tables without leaving any chair free, how many tables are required? If each prime number attender has to serve equal number of customers, how many customers should each one get to serve?
6 tables are required. Each prime number attender should serve 3 customers each.
The prime numbers between 1 and 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
All the numbers other than prime numbers are composite numbers.
The composite numbers from 1 to 100 are: 1, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.
Now, as there are 25 primes and 75 composites in the group that visited the restaurant, we can calculate the number of tables required by dividing the number of people by the seating capacity of each table.
Each table has a seating capacity of 15, so the number of tables required will be: Number of tables = (Number of customers)/(Seating capacity of each table)Number of customers = 25 (the number of primes) + 75 (the number of composites) = 100Number of tables = 100/15 = 6 tables
Therefore, 6 tables are required.
Now, as each prime number attender has to serve an equal number of customers, we need to calculate how many customers each one should serve.
Each prime attender has to serve 75/25 = 3 customers each, as there are 75 composites and 25 primes.
Thus, each prime number attender should serve 3 customers each.

a) Based on the given information, the best location in Buffalo for Subway to open the new restaurant is (1) , with a total weighted score of
. (Enter your response rounded to two decimal places.)
b) If the weights for Space and Traffic density are reversed, the best location in Buffalo for Subway to open the new restaurant will be (2) , with a total weighted score of . (Enter your response rounded to two decimal places.)
(1) Northside Mall Maitland Baptist Church
(2) Maitland Northside Mall Baptist Church
a) The best location is the Baptist Church, with a weighted score of 69.5.
b) The best location will be the Baptist Church, with a weighted score of 70.5.
How to obtain the best location?The best location is obtained considering the location that has the highest score.
The scores are computed using the weighted mean, which is the sum of each score by it's weight.
The score for Maitland is given as follows:
Maitland = 0.30 x 60 + 0.25 x 40 + 0.20 x 50 + 0.15 x 50 + 0.10 x 80 = 53.5.
The score for Baptist Church is given as follows:
Baptist Church = 0.30 x 70 + 0.25 x 80 + 0.20 x 80 + 0.15 x 70 + 0.1 x 20 = 69.5. (highest score).
The score for Northside Mall is given as follows:
Northside Mall = 0.30 x 80 + 0.25 x 30 + 0.20 x 60 + 0.15 x 40 + 0.10 x 90 = 58.5.
Then for item b, the weights for Space and Traffic Density are reversed, and thus the scores are given as follows:
Maitland = 0.20 x 60 + 0.25 x 40 + 0.30 x 50 + 0.15 x 50 + 0.10 x 80 = 52.5.Baptist Church = 0.20 x 70 + 0.25 x 80 + 0.30 x 80 + 0.15 x 70 + 0.1 x 20 = 70.5. (still highest).Northside Mall = 0.20 x 80 + 0.25 x 30 + 0.30 x 60 + 0.15 x 40 + 0.10 x 90 = 56.5.More can be learned about the weighted mean at https://brainly.com/question/24398353
