Everyone knows that cats are nocturnal.
In light of this fact, it is best if the firm adjusts its hurdle rate (i.e., cost of capital) upward to compensate for this fact.
<h3>What is hurdle rate?</h3>
A hurdle rate is known to be the lowest rate of return that is needed on a project or any kind of investment.
Note that Some projects do take an undoubtedly result in zero and as such, In light of this fact, it is best if the firm adjusts its hurdle rate (i.e., cost of capital) upward to compensate for this fact.

The probability that X is greater than 70 and less than 90 is; 0.85
<h3>How to find the probability?</h3>
Let X be the binomial random variable with the parameters:
n = 200
p = 0.4
Then, the random variable Z defined as:
Z = (X - np)/(√(np(1 - p)
The probability that X is greater than 70 and less than 90 is expressed as; P(70 < X < 90)
At X = 70, we have;
Z = (70 - (200*0.4))/(√(200 * 0.4(1 - 0.4))
Z = -1.44
At X = 90, we have;
Z = (90 - (200*0.4))/(√(200 * 0.4(1 - 0.4))
Z = 1.44
Thus, the probability would be expressed as;
P(-1.44 < Z < 1.44)
From online p-value calculator, we have;
P(-1.44 < Z < 1.44) = 0.85
Complete question is;
Suppose that X is a binomial random variable with n = 200 and p = 0.4 Approximate the probability that X is greater than 70 and less than 90.

The terminology for a preset command that is used in a spreadsheet is a: function.
<h3>What is a spreadsheet?</h3>
A spreadsheet refers to a to a document which comprises cells that are arranged in a tabulated format with rows and columns. Also, a spreadsheet is typically used in various field to do the following on a data:
<h3>What is a function?</h3>
In Computer technology, a function refers to a named portion of a block of executable code that can be used as a preset command to perform a specific task, which is usually a single, related action.
In this context, we can infer and logically deduce that a function is the terminology for a preset command that is used in a spreadsheet.
