Answer:
Step-by-step explanation:
We have the equation of the position of the object
We need to solve the equation for the variable a
Subtract and
on both sides of the equality
multiply by 2 on both sides of equality
Divide between on both sides of the equation
Finally
A unit rate simply means how many of one type of units you get per 1 other type of unit.
Examples of that:
This is rate of fluid flow of some pump for example. It pumps 300 liters every second.
Other example:
This is example for speed. Somebody is moving at 50 kilometers per hour (every hour he travels 50 kilometers)

Answer:
A. .1070
Step-by-step explanation:
For each customer, there are only two possible outcomes. Either they make a purchase, or they do not. The probability of a customer making a purchase is independent from other customers. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Forty-four percent of customers who visit a department store make a purchase.
This means that
What is the probability that in a random sample of 9 customers who will visit this department store, exactly 6 will make a purchase?
This is when n = 9. So
So the correct answer is:
A. .1070
