Answer:
Simplified radical form of 4√32 + 6√50 is 46√2
Step-by-step explanation:
Given,
4√32 + 6√50
This can be simplified as:
4√32 + 6√50
{Since √32 = 4√2 and √50 = 5√2}
So we can write
or 4×4√2 + 6×5√2
or 16√2 + 30√2
or 46√2 , this is the answer.
Hence we get simplified radical form as 46√2.
Correlation coefficient of the data is 0.9.
Answer: Option C.
<u>Explanation:</u>
Correlation is the relation of one variable with the other variable. It shows the effect on one variable because of the other variable. The coefficient of the correlation varies from 1 to -1.
The correlation coefficient of this scatterplot is 0.9 because the data points are not scattered in this scatterplot and are rather clustered. Moreover the slope is from left to right which is in the upward direction. So the coefficient is positive.
Answer:
28,54
Step-by-step explanation:
there are two 59's so that would go right and 19 , 27 just go to left
