For this case we have that by definition, the point-slope equation of a line is given by:
We have the following points:
We chose a point:
Substituting in the equation we have:
Finally, the equation is:
Answer:
OPTION C
Answer:
yo have to think very hard about it
Answer:
<em>42.7716% of the variation in the number of bags of trash collected can be explained by differences in the number of volunteers.</em>
Step-by-step explanation:
The correlation coefficient (r) between the number of volunteers x and the number of bags of trash collected y is 0.654
<u>For finding the percent of the variation</u> in one variable explained by the other variable, we just <u>need to take square of the correlation coefficient</u>.
Here,
So,
Now, for converting it into percentage, we will multiply it by 100.
So,
Thus, 42.7716% of the variation in the number of bags of trash collected can be explained by differences in the number of volunteers.
Answer:
1e+300
Step-by-step explanation:
I counted with my fingers
60% of 20 is (0.6 x 20) = 12 passes
There are a further 30 quizzes remaining (50 total during the year minus 20 already written)
80% of 30 is (0.8 x 30) = 24 passes
The student has passed (12 + 24) = 36 quizzes out of 50 total, giving an overall pass percentage of ((36 / 50) x 100)) = 72%.
