Answer:
The average rate of change in the balance over the interval t = 0 to t = 5 is of $20.82 a year. This means that the balance increased by $20.82 a year over the interval t = 0 to t = 5.
Step-by-step explanation:
Given a function y, the average rate of change S of y=f(x) in an interval 
will be given by the following equation:
In this problem, we have that:
Find the average rate of change in the balance over the interval t = 0 to t = 5.
Then
The average rate of change in the balance over the interval t = 0 to t = 5 is of $20.82 a year. This means that the balance increased by $20.82 a year over the interval t = 0 to t = 5.
Y + 3 = x - 1
- 3 - 3
y = x - 4
The slope-intercept form of the equation of the line is y = x - 4.
The correct answer would be C
Okay, the first thing to do is to make it so you're multiplying everything instead of dividing by that last fraction. To divide by a fraction, you just multiply by its reciprocal. So then, it's 15/124 x 230/30 x 124/230. After that, let's organize it into one single giant fraction since order of operations allows us to arrange division and multiplication however we want. Then it's 15x230x124 / 124x30x230. Then, you'll notice that the 230s and 124s can both be canceled out, leaving 15/30. After simplifying, your final answer is 1/2.
Answer: 83
Step-by-step explanation:
Since the student want to have a mean of 83 in the 7 tests, the total score of the tests will be:
= 83 × 7
= 581
Then, we add the value of the 6 tests and this will be:
= 88 + 73 + 81 + 83 + 79 + 94
= 498
We will now subtract 498 from 581 and this will be:
= 581 - 498
= 83
He needs to score 83 in the 7th test
