Make a table with integer values of x from 1 to 4
Jet001 [13]
So we see our equation, clear:
y=8^x
Let's just plug in values of x from 1-4.
y= 8^1=8; So, it would be (1,8).
y= 8^2=64; So, it would be (2, 64).
y = 8^3= 512; So, it would be (3,512).
y= 8^4 = 4096; So, it would be (4, 4096).

Sandra worked 6 hours on Wednesday, 5 hours on Thursday, and 4 hours on Friday. What is the mean number of hours she worked over
gladu [14]

Answer:

The mean should be D. 5

Step-by-step explanation:

The mean means the average which in this order (4, 5, 6) The direct middle is 5, making it the average since there are only 3 numbers in the first place.

You can mark out A (2) and B (3) instantly because they are lower than any of beginning numbers, and it's not C (4) as 'mean' doesn not mean the lowest, which leaves you with D (5)

May I have brainliest please? :)

How would you characterize the relationships between the hours spent on homework and the test scores?
uysha [10]

Answer:

There is a positive correlation between the number of hours spent on homework and the test scores.  So, the more homework you do, the better your test score.  

Step-by-step explanation:

The data given is representative of a scatter plot, which shows a relationship with two sets of data that, when using a line of best fit, will show either a positive correlation (increasing), a negative correlation (decreasing) or no correlation (the data shows no overall pattern).  In this case, you can see that the overall pattern of data is increasing, or a positive correlation.  Which means that, in general, the more hours of homework you do, the more likely you are to receive a better test score.
