Answer:
Hi!
Around 2208.97 dollars
Step-by-step explanation:
A=P(1+r/n)^nt This is the compound interest rate equation.
According to the problem, Principal is 2000 with annual rate of 2.5%, it was being compounded semiannually(twice a year).
Thus,
P=2000. r/n=2.5%/2 nt=2*4, 8
A=2000(1+0.0125)^8
A=2208.97
Answer:
(1/2)X - 5
Step-by-step explanation:
Answer:
Step-by-step explanation:
Solving for x:
In this form is easy to identify the factors of the quadratic function: 
. The two solutions are the values that make each of the factors equals to zero.
Answer: 76 baseballs and 24 bats were ordered.
Step-by-step explanation:
Let x represent the number of baseballs that were ordered for the summer basketball camp.
Let y represent the number of bats that were ordered for the summer basketball camp.
Bakersfield parks and recreation department ordered a total of 100 baseballs and bats for the summer basketball camp. This means that
x + y = 100
Baseballs cost $4.50 each and bats cost $20 each. The total purchase was $822. This means that
4.5x + 20y = 822 - - - - - - - - - - -1
Substituting x = 100 - y into equation 1, it becomes
4.5(100 - y) + 20y = 822
450 - 4.5y + 20y = 822
- 4.5y + 20y = 822 - 450
15.5y = 372
y = 372/15.5
y = 24
x = 100 - y = 100 - 24
x = 76
We need to find the mean of a set of five values.
In order to do so, we need to add all the values, and then divide the result by the total number of values.
So, adding those values, we obtain:
Notice that since they are all negative values, the result is the sum of their absolute values with the minus sign.
Now, since the total number of values in the given set is 5, we need to divide the previous result by 5. We obtain:
