To find X, we can divide 5 into 40.
40 divided by 5 is 8.
Now we can do 5 x 8. That is 40.
X=40
OR we can do it another way.
40 divided by 5 is 8.
Cross out 5 divided by 5.
Now we have 8. Still.
X is 8
Answer: The answer is the 3rd one
Answer:
B: 280
Step-by-step explanation:
The regression line predicts that when x equals 5:

In order to find the value for y, one must simply apply the following logarithmic property:
if :
then: 
Applying it to this particular problem:

Therefore, the regression line predicts y will equal 280 when x equals 5.
Answer:
Step-by-step explanation:
<u>The data given:</u>
- 93, 81, 94, 71, 89, 92, 94, 99
<u>Put the data in the ascending order:</u>
- 71, 81, 89, 92, 93, 94, 94, 99
<u>Since the data size is even, the median is the average of middle two:</u>
- median = (92 + 93)/2 = 92.5
