Let's call the time it takes to install all the chairs from start to finish "t". The workers install 840 chairs per day, so in "t" days they will have installed 840 * t chairs.
At the end of 5 days, they still have 240 chairs to install, so they have installed 840 * 5 chairs so far. We can use this information to write an equation:
840 * t - 840 * 5 = 240
Expanding and simplifying the equation gives us:
840t - 4200 = 240
Adding 4200 to both sides gives us:
840t = 4440
Finally, dividing both sides by 840 gives us:
t = 5.2857142857...
So it takes approximately 5.29 days to install all the chairs from start to finish.

What is a number line?In Mathematics, a number line can be defined as a type of graph with a graduated straight line which comprises both positive and negative numbers that are placed at equal intervals along its length.
This ultimately implies that, a number line primarily increases in numerical value towards the right from zero (0) and decreases in numerical value towards the left from zero (0).
In this context, we can reasonably infer and logically deduce that all numerical values (numbers) to the left are always less than numerical values (numbers) located to the right of a number line such as the following:
-25 < 0.
-25 < 5.
-25 < -5.

Denton
When mapped on a coordinate plane, the coordinates of 2 of the towns are Albion (5, 5) and Denton (-7,-3). Beacon
is exactly in the middle of Albion and Denton, and Casper is exactly in the middle of Denton and Beacon.
What are the coordinates of Casper?
The coordinates of Casper which lies exactly in the middle of Denton and Beacon are (-4, -1).
What are the Coordinates?Coordinates are defined as the set of points in a coordinate plane or space, which describes the position of that point in that plane or space.
In a coordinate plane, the midpoint of two points (x₁, y₁) and (x₂, y₂) is the point (x, y) such that their measures are,
x = (x₁ + x₂) / 2
y = (y₁ + y₂) / 2
First, we can write the given measures.
Coordinates of Albion = (5, 5)
Coordinates of Denton = (-7, -3)
Given that, Beacon is lying exactly in the middle of Albion and Denton.
Let the coordinates of Beacon be (x, y).
Using the formula above,
x coordinate of Beacon = (5 + -7) / 2 = -1
y coordinate of Beacon = (5 + -3) / 2 = 1
Coordinates of Beacon are thus (-1, 1).
Casper is lying exactly in the middle of Denton(-7, -3) and Beacon (-1, 1).
Let (x' , y') be the coordinates of Casper.
Using the same formula,
x' = (-7 + -1) / 2 = -4
y' = (-3 + 1) / 2 = -1
Hence the coordinates of Casper are (-4, -1).

Surface area of a cube is 150m².The length of its edge is
Answer:
the length of the edge of the cube is 5 meters
Step-by-step explanation:
The surface area of a cube can be found using the formula:
Surface Area = 6 x (side length)^2.
Since the surface area of this cube is 150 square meters, we can set up an equation to solve for the side length:
150 = 6 x (side length)^2
Dividing both sides by 6, we get:
25 = (side length)^2
Taking the square root of both sides, we find the side length:
side length = sqrt(25) = 5 meters.
So the length of the edge of the cube is 5 meters.

A boat heading out to sea starts out at Point A, at a horizontal distance of 724 feet from a lighthouse/the shore. From that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 16 ∘ . At some later time, the crew measures the angle of elevation from point B to be 5 ∘ . Find the distance from point A to point B. Round your answer to the nearest foot if necessary.
The distance from point A to point B is 1496 ft.
What is distance?Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.
Given that, a boat is at point A which at 724 ft distance from a lighthouse making an angle of elevation to the lighthouse’s beacon-light of 16°, when moved to some distance B making an angle of elevation to the lighthouse’s beacon-light of 5°, we need to find the distance from point A to point B.
Refer to the figure attached,
The whole scene is creating two right triangles, rt Δ CDA and rt Δ CDB
Using the trigonometric functions, in rt Δ CDA,
We have,
tan 16° = CD/DA
CD = tan 16° × 724
CD = 207.6
Therefore, the height of the lighthouse is 207.6 ft
Now,
tan 5° = CD/DB
DB = CD / tan 5°
DB = 2373
The distance between A and B = DB-DA = 2373 - 724 = 1496
Hence, the distance from point A to point B is 1496 ft.

False.
It should be stated that the likelihood of the intersection of two events occurring is always less than the likelihood of the events occurring together.
It is always less likely than or equal to the likelihood of either event occurring alone for an intersection of two events, which is the chance that both occurrences take place.
In other words, the probability of the intersection and the probability of the union are subsets of one another.
The chance of the intersection of two events occurring can never be greater than the likelihood of the union of two events occurring, hence that is the right statement.

Question 10:
A plumber cut a
pipe into 5
equal pieces and had 27 cm of the pipe left. For a second
pipe 15m long, he cut 11 pieces of the same length as that of each piece cut from the
first pipe and had 15 cm of the second pipe left. What was the length, in cm, of each
shorter piece of the second pipe? What was the length of the first pipe originally?
If a plumber cut a pipe into 5 equal pieces and had 27 cm of the pipe left. the length of the first pipe originally is 702 cm.
How to find the length?Let's call the original length of the first pipe "L"
Let the length of each of the 5 equal pieces "x".
set up the equation:
5x + 27 = L
Each piece of the second pipe is "x" cm long. The second pipe is 15 m long, which is equivalent to 1500 cm. The plumber cut 11 pieces of the same length as each of the 5 equal pieces from the first pipe, so the total length of the 11 pieces is:
11x
The plumber had 15 cm of the second pipe left over after cutting 11 pieces, so we can set up another equation:
1500 - 11x = 15
Solving for "x" in the second equation:
11x = 1485
x = 135
So each piece of the second pipe is 135 cm long.
To find the original length of the first pipe, we can substitute x = 135 into the first equation and solve for L:
5x + 27 = L
5(135) + 27 = L
L = 702
Therefore, the original length of the first pipe was 702 cm.

An inappropriate fraction is created by adding the numerator to a mixed fraction after multiplying the denominator of the proper fraction by the whole number it is related to.
How change a fraction into a mixed fraction?
By denominator, divide the numerator.
Take the quotient as a whole number and use the remaining amount as the proper fraction's numerator while maintaining the original denominator.
Given that the thickness of the plate is 1 7/8 in.
Convert the mixed fraction into improper fraction:
1 7/8 = 15/8
The machine shaves of 7/32 in, thus after one pass we have:
15/8 - 7/32
Take the LCM:
60/32 - 7/32 = 53/32
Covert the fraction into mixed fraction:
53/32 = 1 21/ 32 in
After three passes through the machine the thickness of the plate is:
15/8 - 3(7/32)
60/32 - 21/32 = 39/32
Covert into mixed fraction:
39/32 = 1 7/32 in

1) The probability of picking more than 1 apple is 0.8. 2) the expected number of apples you can pick each year is 2.65. 3) the expected number of apples you can pick each year is 2.65.
To find the probability of picking more than 1 apple, we need to find the sum of the probabilities of picking 2, 3, and 4 apples. Using the table, we have P(N>1) = P(2) + P(3) + P(4) = 0.15 + 0.35 + 0.3 = 0.8. So, the probability of picking more than 1 apple is 0.8. The expected number of apples you can pick each year can be calculated using the formula: E(N) = ∑N * P(N), where the sum is taken over all possible values of N. Using the table, we have E(N) = (1 * 0.1) + (2 * 0.15) + (3 * 0.35) + (4 * 0.3) = 0.1 + 0.3 + 1.05 + 1.2 = 2.65. So, the expected number of apples you can pick each year is 2.65. To find the probability of picking 3 apples, given that your father picked more than 1 apple, we need to use the conditional probability formula. We have P(3|N>1) = P(3 and N>1) / P(N>1) = P(3) / P(N>1) = 0.35 / 0.8 = 0.4375. So, the probability of your father picking 3 apples, given that he picked more than 1 apple, is 0.4375

Bob is interested in examining the relationship between the number of bedrooms in a home and its selling price. After downloading a valid data set from the internet, he calculates the correlation. The correlation value he calculates is only 0.05.What does Bob conclude?
A correlation coefficient of 0.05 indicates a very weak positive correlation between the number of bedrooms and selling price.
When Bob calculates the correlation between the number of bedrooms in a home and its selling price and obtains a value of only 0.05, he can conclude that there is little to no linear relationship between the two variables.
Correlation is a statistical measure that indicates the degree to which two variables are related and the direction of the relationship. A correlation coefficient ranges from -1 to 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates a perfect positive correlation.
A correlation coefficient of 0.05 is very close to 0, indicating that there is almost no linear relationship between the number of bedrooms in a home and its selling price.
However, it is important to note that a low correlation coefficient does not necessarily mean that there is no relationship between the variables, as there could be a non-linear relationship or other types of relationships that cannot be captured by a correlation coefficient.
Therefore, Bob should further analyze the data set and explore other statistical measures or techniques to fully understand the relationship between the number of bedrooms in a home and its selling price.

The two numbers can be found by using basic algebra. To solve for the two numbers, we can set up two equations, one for the sum and one for the difference. For the sum, we can set up the equation: x + y = 147. For the difference, we can set up the equation: x - y = 25.
