For the question of total area of the cuboid is 200cm^.
I understand where we divide 150 by 4.
But why do I need to multiply by 5, when there are 6 faces.
You need to multiply by 5 instead of 6 because each pair of opposite faces on a cuboid has the same area, so by considering one face from each pair, you ensure that you don't count any face twice.
When calculating the total surface area of a cuboid, you need to understand the concept of face pairs.
A cuboid has six faces, but each face has a pair that is identical in size and shape.
Let's break down the reasoning behind multiplying by 5 instead of 6 in the given scenario.
To find the surface area of a cuboid, you can add up the areas of all its faces.
However, each pair of opposite faces has the same area, so you avoid double-counting by only considering one face from each pair. In this case, you have five pairs of faces:
(1) top and bottom, (2) front and back, (3) left and right, (4) left and back, and (5) right and front.
By multiplying the average area of a pair of faces by 5, you account for all the distinct face pairs.
Essentially, you are considering one face from each pair and then summing their areas.
Since all the pairs have the same area, multiplying the average area by 5 gives you the total surface area.
When dividing 150 by 4 (to find the average area of a pair of faces), you are essentially finding the area of a single face.
Then, by multiplying this average area by 5, you ensure that you account for all five pairs of faces, providing the total surface area of the cuboid.
Thus, multiplying by 5 is necessary to correctly calculate the total surface area of the cuboid by accounting for the face pairs while avoiding double-counting.

How many more 41+ year olds have a preference for Enterprise Content Management in comparison to 18-25 year olds (as a %)?
The solution is Option B.
The percentage increment in the preference for Enterprise Content Management is given by the equation A = 366 %
What is Percentage Error?The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage error is the difference between the measured value and the true value , as a percentage of the true value
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Given data ,
Let the percentage increment be represented as A
Now , the equation will be
The number of 41+ year olds having a preference for Enterprise Content Management = 3,215
The number of 18-25 year olds having a preference for Enterprise Content Management = 690
So , the difference in number of preference = 3,215 - 690
On simplifying the equation , we get
The difference in number of preference = 2,525
And , the percentage increase A = ( difference in number of preference / number of 18-25 year olds having a preference for Enterprise Content Management ) x 100
Substituting the values in the equation , we get
The percentage increase A = ( 2525/690 ) x 100
The percentage increase A = 3.659 x 100
The percentage increase A = 366 %
Therefore , the value of A is 366 %
Hence , the percentage increment is 366 %

What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of first line be = A
Let the equation of second line be = B
Now , the value of A is
y = 3x - 8
The value of B is
y = -2x - 3
The slope of the equation A is 3 and the y intercept is -8
The slope of the equation B is -2 and the y intercept is -3
The equations are solved graphically below , and the point of intersection is P ( 1 , -5 )
Since , the point of intersection of two lines is at P , the point P will be the solutions to the system of equations A and B
So , the point is P ( 1 , -5 ) and the solution is
The value of x = 1
The value of y = -5
Substitute the value of x and y in the equation A , we get
y = 3x - 8
-5 = 3 ( 1 ) - 8
-5 = 3 - 8
-5 = -5
So , the equation of line satisfies the point P ( 1 , -5 )
Substitute the value of x and y in the equation B , we get
y = -2x - 3
-5 = -2 ( 1 ) - 3
-5 = -2 - 3
-5 = -5
So , the equation of line satisfies the point P ( 1 , -5 )
Hence , The system of equations are solved graphically and the point of intersection is P ( 1 , -5 )

A blue boat and a red boat are on the same side of a lake and are 18 miles apart. The blue boat is 30 miles from a lighthouse on the opposite side of the lake. The angle formed by the boats and the lighthouse, and whose vertex is at the blue boat, measures 120°. Find the distance from the red boat to the lighthouse. What is the angle made from the lighthouse to the two boats?
9514 1404 393
Answer:
red boat distance: 42 milesangle at lighthouse: 22°Step-by-step explanation:
The Law of Cosines can be used to find the distance from the red boat to the lighthouse.
b² = l² +r² -2lr·cos(B)
b² = 18² +30² +2·18·30·cos(120°) = 1764
b = √1764 = 42
The distance from the red boat to the lighthouse is 42 miles.
__
The angle at the lighthouse can be found using the law of sines.
sin(L)/l = sin(B)/b
L = arcsin(l/b·sin(B)) = arcsin(18/42·sin(120°)) ≈ 21.79°
The angle between the boats measured at the lighthouse is about 22°.

what is the approximate probability that in a random sample of 1000 individuals who have purchased fries at McDonald’s, at least 40 can taste the difference between the two oils? (2.5 pts.)
Complete Question
In response to concerns about nutritional contents of fast foods, McDonald's has announced that it will use a new cooking oil for its French fries that will decrease substantially trans fatty acid levels and increase the amount of more beneficial polyunsaturated fat. The company claims that only 3 out of 100 people can detect a difference in taste between the new and old oils. Assuming that this figure is correct (as a long-run proportion), what is the approximate probability that in a random sample of 1000 individuals who have purchased fries at McDonald's, at least 40 can taste the difference between the two oils? (2.5 pts.)
Answer:
The probability is \(P(\^ p \ge 0.04 ) = 0.03216\)
Step-by-step explanation:
From the question we are told that
The population proportion is \(p = \frac{3}{100} = 0.03\)
The sample size is n = 1000
Generally the mean of this sampling distribution is \(\mu_{x} = 0.03\)
Generally the standard deviation of this sapling distribution is mathematically evaluated as
\(\sigma = \sqrt{\frac{p (1 - p)}{n} }\)
=> \(\sigma = \sqrt{\frac{0.03 (1 - 0.03)}{1000} }\)
=> \(\sigma = 0.0054\)
Generally the sample proportion when the number of those that can taste the difference is 40 is mathematically represented as
\(\^ p = \frac{40}{1000} = 0.04\)
Generally the approximate probability that in a random sample of 1000 individuals who have purchased fries at McDonald's, at least 40( \(\^ p = 0.04\)) can taste the difference between the two oils is mathematically represented as
\(P(\^ p \ge 0.04 ) = 1 - P(\^ p < 0.04 )\)
Here
\(P(\^ p < 0.04 ) = P(\frac{ \^ p - \mu_{x}}{\sigma } < \frac{0.04 - 0.03}{0.0054} )\)
\(\frac{\^ p -\mu}{\sigma } = Z (The \ standardized \ value\ of \ \^ p )\)
=> \(P(\^ p < 0.04 ) = P(Z < 1.85 )\)
From the z table the probability of (Z < 1.85 ) is
\(P(Z < 1.85 ) = 0.96784\)
So
\(P(\^ p < 0.04 ) = 0.96784\)
So
\(P(\^ p \ge 0.04 ) = 1 - 0.96784\)
=> \(P(\^ p \ge 0.04 ) = 0.03216\)

The length of the hypotenuse is 12.52 yards.
Given that a right triangle, we need to find the value of the hypotenuse x,
Trigonometric ratios can be calculated by taking the ratio of any two sides of the right-angled triangle.
We can evaluate the third side using the Pythagoras theorem, given the measure of the other two sides. We can use the abbreviated form of trigonometric ratios to compare the length of any two sides with the angle in the base.
Let us consider a right-angled triangle with one of its acute angles to be x. Then the cosine formula is, cos x = (adjacent side) / (hypotenuse), where "adjacent side" is the side adjacent to the angle x, and "hypotenuse" is the longest side (the side opposite to the right angle) of the triangle.
We know that, the cosine of the angle is the ratio of the base to the hypotenuse,
So,
Cos 37° = 10 / x
x = 10 / Cos 37°
x = 12.52
Hence the length of the hypotenuse is 12.52 yards.
