How to calculate percentage :
To determine the percentage, we have to divide the value by the total value and then multiply the resultant by 100Percentages have no dimension. Hence it is called a dimensionless number. If we say, 50% of a number, then it means 50 per cent of its whole.Percentages can also be represented in decimal or fraction form, such as 0.6%, 0.25%, etc.The formula used to calculate percentage is: (value/total value)×100%.To find 15% of 100, rewrite the 15% as 0.15. Then just multiply 0.15 x 100, to get the solution of 15.To learn more about Calculating rent refer :

yoonie is a personnel manager in a large corporation. each month she must review 16 of the employees. the time that takes to do a review has a bell shaped distribution with a mean of four hours and a standard deviation of 1.2 hours. what is the probability that the average time of 16 reviews will take yoonie from 3.5 to 4.25 hours?
The probability that the mean of a month's reviews will take Yoonie from 3.5 to 4.25 hours is 0.7492.
The random variable X is defined as the time it takes her to complete one review.
The random variable X follows a Normal distribution with parameters μ = 4 hours and σ = 1.2 hours.
A random sample of n = 16 reviews are selected as a set.
Compute the probability that the mean of a month’s reviews will take Yoonie from 3.5 to 4.25 hours as follows:
P(3.5 < X < 4.25) = P(3.5-4/1.2√16 < x- μ /σ/√n < 4.25-4/1.2/√16)
=P(-1.67 < Z < 0.83)
= P(Z < 0.83) - (P(Z < -1.67)
= 0.7967 - 0.0475
= 0.7492
Thus, the probability that the mean of a month’s reviews will take Yoonie from 3.5 to 4.25 hours is 0.7492.

The weight of the truck, When a loaded truck pulls onto it, the boat sinks an additional 5.00cm into the river is 11,788 N.
To discover the weight of the truck, we ought to utilize the concept of buoyancy.
When the truck pulls onto the vessel, it uproots a sum of water that breaks even with its claimed weight. The weight of this uprooted water makes an upward buoyant constraint on the pontoon.
The watercraft sinks an extra 5.00 cm, which suggests that the buoyant constraint breaks even with the weight of the truck furthermore the weight of the uprooted water, and this adds up to the weight causing the boat to sink assist.
Let's accept that the thickness of water is 1000 kg/m³ (this can be ordinary esteem for new water). The volume of water uprooted by the pontoon is rise to its length times its width times the profundity it sinks into the water:
V = (6.00 m)(4.00 m)(0.05 m) = 1.20 m³
The weight of this uprooted water is:
Wwater = Vρg = (1.20 m³)(1000 kg/m³)(9.81 m/s²) ≈ 11,788 N
where ρ is the thickness of water and g is the speeding up due to gravity.
Since the buoyant drive is broken even with the weight of the truck furthermore the weight of the uprooted water, we have:
Wtruck + Wwater = Fbuoyant
where Wtruck is the weight of the truck and Fbuoyant is the buoyant drive. Ready to improve this condition to illuminate for the weight of the truck:
Wtruck = Fbuoyant - WWater
The buoyant drive is broken even with the weight of the water uprooted by the watercraft, which we calculated prior to being around 11,788 N. In this manner:
Wtruck = 11,788 N - 0
Wtruck ≈ 11,788 N
So, the weight of the truck is around 11,788 N.

convert million gallons per day to cubic feet per second
The flow rate of 5 MGD is equivalent to 7.73615 cfs
To convert million gallons per day (MGD) to cubic feet per second (cfs), we need to use the conversion factor between the two units. The conversion factor is 1 MGD = 1.54723 cfs.
Therefore, to convert MGD to cfs, we can multiply the given value of MGD by the conversion factor. For example, if we have a flow rate of 5 MGD, we can convert it to cfs as follows:
5 MGD x 1.54723 cfs/MGD = 7.73615 cfs
So, the flow rate of 5 MGD is equivalent to 7.73615 cfs. Similarly, we can convert any given flow rate in MGD to cfs by using the same conversion factor.
It is important to note that these units are commonly used in the context of water supply and distribution systems, where flow rates are a crucial factor in the design and operation of such systems. Therefore, knowing how to convert between different flow rate units is essential for engineers and technicians working in this field.

The slope of the line that contains these points is 0.75.
The slope of a line is the change in y-values divided by the change in x-values. In other words, it is the rise over the run. We can use the points given to calculate the slope.
Let's take the first two points (9, -24) and (13, -21) and use the formula for slope:
slope = (y2 - y1) / (x2 - x1)
slope = (-21 - (-24)) / (13 - 9)
slope = (3) / (4)
slope = 0.75
We can do the same with the other two points (17, -18) and (21, -15):
slope = (-15 - (-18)) / (21 - 17)
slope = (3) / (4)
slope = 0.75
Since the slope is the same for both sets of points, we can conclude that the slope of the line that contains these points is 0.75.

Use implicit differentiation to find an equation of the tangent line to the curve at the given point. x2/3+y2/3=4;(−3√3,1)�2/3+�2/3=4;(−33,1)
To find the equation of the tangent line to the curve at the given point, we need to use implicit differentiation. This involves differentiating both sides of the equation with respect to x, treating y as a function of x.
Taking the derivative of both sides of the equation, we get:
(2/3)x^(-1/3) + (2/3)y^(-1/3)*dy/dx = 0
Now we can solve for dy/dx:
dy/dx = -(y^(1/3)/x^(1/3))
To find the equation of the tangent line, we need to find the slope of the tangent line at the given point. Plugging in the coordinates (-3√3,1) into our expression for dy/dx, we get:
dy/dx = -(1^(1/3)/(-3√3)^(1/3)) = -(1/3)
So the slope of the tangent line is -1/3.
Next, we need to find the y-intercept of the tangent line. To do this, we can use the point-slope form of a line:
y - y1 = m(x - x1)
Plugging in the values we have so far, we get:
y - 1 = -(1/3)(x + 3√3)
Simplifying this equation, we get:
y = -(1/3)x - √3 + 1
So the equation of the tangent line to the curve x^(2/3) + y^(2/3) = 4 at the point (-3√3,1) is y = -(1/3)x - √3 + 1.
To start, we'll use implicit differentiation to find dy/dx (the derivative of y with respect to x). Differentiating both sides of the equation with respect to x, we get:
(2/3)x^(-1/3) + (2/3)y^(-1/3)(dy/dx) = 0.
Now, we can solve for dy/dx:
(2/3)y^(-1/3)(dy/dx) = -(2/3)x^(-1/3).
dy/dx = -[x^(-1/3)/y^(-1/3)].
Next, plug in the given point (-3√3, 1) into the expression for dy/dx:
dy/dx = -[(-3√3)^(-1/3) / 1^(-1/3)] = -(-1/3).
Therefore, dy/dx = 1/3 at the given point.
Now, we have the slope of the tangent line (1/3) and the point (-3√3, 1). Using the point-slope form of a linear equation, we can find the equation of the tangent line:
y - 1 = (1/3)(x + 3√3).
Thus, the equation of the tangent line to the curve x^(2/3) + y^(2/3) = 4 at the point (-3√3, 1) is y - 1 = (1/3)(x + 3√3).

How many grams of sugar would he need to bake 10 cookies
The amount of sugar that will be needed is 35g.
What quantity will be required?To solve the question we need to express the values in such a way that they are proportional to each other. First, we are told that baking 100 cookies will require 350 grams of sugar. This can be expressed thus:
100 cookies = 350g
Next, we are to determine how many grams will be needed to bake 10 cookies. A simple analogy will show that the required grams will be lesser than the original since the value is smaller.
So, if 100 cookies = 350g,
10 cookies will be equal to:
10 cookies × 350g/100
3500/100
=35g
Thus, 35 grams of sugar will be needed.
