Answer: The answer that is false is “Initially, Cassie has $20 dollars in her account.”
Step-by-step explanation: The reason why this is false is because the first statement that the slope of the line is -20 is true. The formula for slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Next the initial value is 275 because in these problems the y-intercept is technically the starting value in these problems. So since the initial value is 275 the last statement is false.
Have a nice day!
The answer is B :)
The mean is the average of the set of data.
The best choice from the ones viewable in your picture is B) 1.
With that being said, 1 is used to indicate a perfect fit, which there is not one for this plot.
However, 0 would not be correct either, as 0 implies no correlation. We can see from the graph that there is a correlation.
-0.95 would not work either, as the line appears to trend upward; a negative correlation coefficient indicates it trends down.
A: High School P, because it has the lowest <span>σ
B: High School N, because it has the highest mean</span>
Answer:
Tina ate 3/4 of the whole pan of cornbread.
Step-by-step explanation:
Let the amount of cornbread in the initial pan be <em>x.</em>
<em />
After the dinner party, Tina has 1/2 of x left; That is 1/2x
If she eats 1/2 of the leftover, that will be 1/2 of 1/2x that is eaten. This will be 1/4x that is eaten.
To find the potion of the whole pan that Tina ate, we will add the potion she ate during the party to the portion of the leftover she ate the next night.
That will be 1/2x + 1/4x =3/4x
Therefore, Tina ate 3/4 of the whole pan of cornbread.
