Answer:
By an online search, i found that the options are:
Option A. A(10)
Option B. A(11)-A(9)
Option C. A(10)/10
Option D. A’(10)
Let´s start by defining the concept of a derivative.
When we have a function f(x), the derivative, f´(x), is a measure of the rate of change of f(x) with respect to the variable x.
Then if A(t) represents the area covered by the oil, A´(t) is the rate of change of this area as a function of t.
Particularly, A´(10), will be the rate of change at t = 10.
Then the correct option is: Option D. A´(10)
So on the first one, check the first picture, solve for "x" and "y" respectively
on the second one, check the second picture, the left-half, solve for "x"
on the last one, are they similar? check the second picture, right-half
Answer:
The opening price of the stock in the beginning of the day was $4.
Step-by-step explanation:
To be able to calculate the price of the stock at the beginning of the day, you have to consider that the equation to calculate the final price is equal to the opening price multiply for the result of one plus the increase or decrease percentage, which is:
final price=opening price*(1+0.04)
Now, you know that the final price is $4.16, so you can replace this value in the formula and solve for the opening price:
4.16=opening price*1.04
opening price=4.16/1.04
opening price=4
According to this, the answer is that the opening price of the stock in the beginning of the day was $4.
A sample of size n taken from a population with mean = µ and standard deviation = σ has sample mean = µ and sample s.d. = σ/√n.
If the final exam scores are normally distributed, and X is a random variable for the mean of a sample, then
Pr[X < 70] = Pr[(X - 73) / (7.8/√24) < (70 - 73) / (7.8/√24)]
… ≈ Pr[Z < -1.8842]
… ≈ 0.0298
(where Z is normally distributed with µ = 0 and σ = 1).
