No, the order does not matter.
Sometimes, depending on the question being asked there can be an order that is easier to use (for example if the plane is represented in a drawing it can sometimes be nice to name the points from left to right or top to bottom as they appear in the drawing, or you might like to name the points alphabetically) but this is NOT required and is not "more correct" than any other order.
Answer:
The correct answer is 10 units.
Step-by-step explanation:
Profit function of a small business is given by P(x) = 0.3 + 7x - 40, where x is the number of units sold.
The small business intend to make a profit of $60.
To find out the number of units the business has to sell in order to have a profit of $60 is given by,
P(x) = 0.3 + 7x - 40 = 60
⇒ 0.3 + 7x - 100 = 0
⇒ 3 + 70x - 1000 = 0
⇒ x = -70 ± ×
⇒ x = -70 ± 130 ×
⇒ x = 10 or -
Quantity sold cannot be negative giving us the value of x as 10 units.
Answer:3 and 7
Step-by-step explanation:
Answer:
And we can use the z score formula given by:
And if we find the z scores for the limits of the interval we got:
And we want to find this probability:
And we can use the foolowing excel command and we got:
=NORM.DIST(0.878;0;1;TRUE)-NORM.DIST(-0.4;0;1;TRUE)
And we got:
Step-by-step explanation:
For this case we know the following parameters:
We select a sample size of n =59. So then the sample size is large enough to use the central limit theorem and the distribution for the sample mean is given by:
We want to find the following probability:
And we can use the z score formula given by:
And if we find the z scores for the limits of the interval we got:
And we want to find this probability:
And we can use the foolowing excel command and we got:
=NORM.DIST(0.878;0;1;TRUE)-NORM.DIST(-0.4;0;1;TRUE)
And we got:
