Answer:
B
Step-by-step explanation:
all you need is to solve the first term
2x² - (-3x²) = 5x² ,
b is the only answer with 5x² in it
Answer:B or C
Step-by-step explanation:
I did the test
The table and the plotted data are in the attachment.
Answer and Step-by-step explanation: A line of best fit is the best approximation of the given data. It is used to show the relation of two variables and it can be determined, more accurately, by the Least Square Method.
To use the method, follow the steps:
1) Calculate the mean of the two variables:

2) The Slope of the line is given by:

3) The y-intercept is found by the formula:

For the ripening of bananas, the least square method gives the line:
y = -0.142x + 5.56
The rate of change of a line equation is its slope, so
Rate of change = -0.14
The rate of change of ripening time with respect to exposure time is -0.14, which means the more expose the fruit is, the less time it needs to ripe.
When an event is independent of the other, it means Event A does not influence Event B.
For example, if one was to find the probability of someone owning a car and what there neighbour eats, there is no correlation. In this situation, the events are independent.
