Answer:
Depositing means that you added 50$ to your account. This means that you account increased by an amount of 50.
The integer describing this is +50.
Then, withdrawing means that you took money from the account. This means that your account decreased by an amount of 20.
This can be expressed as a -20 integer.
It would be -145 if its below sea level.
Answer:
1.
E(3) = 0.29
2. See Below
Step-by-step explanation:
1.
According to the formula we would need the derivative, so lets first calculate the derivative of f(p) given.
The rules to use would be 
Also, remember to use chain rule if there is a function inside a function. So we differentiate the "inside" function again.
Now, lets differentiate:
Now, the E(p):
We find E(3) by substituting 3 into "p":
2.
When E(p) = 1, it means the price elasticity of demand is "1". It is the called Unitary Elastic Demand. It means that for every unit change in price, there is the same unit change in demand. The changes of demand and price are proportional to each other.
According to a center for disease control. We can’t compute the probability.
<u>SOLUTION:
</u>
Given that, According to a center for disease control,
The probability that a randomly selected person has hearing problems is 0.157.
The probability that a randomly selected person has vision problems is 0.096.
We have to find whether we can compute the probability of randomly selecting a person who has hearing problems or vision problems by adding these probabilities or not?
The answer is no, because hearing and vision problems are not mutually exclusive.
So, some people have both hearing and vision problems.
These people would be included twice in the probability.
Hence, we can’t compute the probability.
To find the amount of feet in 4 miles you will need to take the amount of feet in 1 mile and multiply that by 4 to receive your answer hope this helps. 5280(feet per mile)*4=21120
