Answer:
A
Step-by-step explanation:
A linear function increases/decreases by a certain amount every year. As it changes 1500 over the first 5 years (300 per year) and 3000 over the next 5 (600 per year), this cannot be liner
A quadratic function goes down then up, or vice versa. This consistently goes up, and is therefore not quadratic
A trigonometric function also goes up and down, so it is not trigonometric
Therefore, as an exponential function can keep going up at different rates over time, this is an exponential function
Answer:
D. negative
Step-by-step explanation:
Let's analyze each answer choice.
A. Zero
A line with a zero slope is a horizontal line. The x values change, but the y values stay the same.
B. Undefined
A line with an undefined slope is a vertical line. The x values don't change and the y values vary.
C. Positive
When a line has a positive slope, the line increases from left to right.
D. Negative
When a line has a negative slope, the line decreases from left to right.
When we move from left to right on the graph, the line moves down. Therefore, this line must have a negative slope and D is correct.
The answer is 4
Since 3.3x 4 is 13.2 and plus 3.0 is 16.2
You can't have a square root of a negative number
The mean absolute deviation is the average of the average. It shows the average distance of the numbers in a data set from the mean. After finding the mean, you find the absolute value of the distance between each number, and find the mean of those numbers to find the mean absolute deviation.
