Answer:
I would’ve worked it out but it’s been years
Step-by-step explanation:
Using the information given we can set up a simple math equation.
(1.6 x 4) + 0.8 + (0.3 × 2) = Paint used
6.4 + 0.8 + 0.6 = Paint used
7.8 = Paint used.
Finally you end up with your answe being B. 7.8 gallons of paint used.
The degree of dispersion in your data collection is indicated by variance.
It is given by the formula:
To determine the values of a certain set of scattered data, the standard deviation formula is utilized. The dispersion of the quantities or data from the mean is how the standard deviation is simply defined. The conclusion drawn from a lower standard deviation is that the results are fairly near to the average. Higher values, on the other hand, indicate a significant dispersion from the mean. The standard deviation number can never be negative, it should be positive.
It is given by the formula:
We have that the mean of the values is:
at 8 AM
at 12 AM
Using the above definitions we have that
at 8 AM
at 12 AM
In general, represents the mean of the differences from the population of matched data.

P=2w+2l
We know that P=90 and l=15 so we can plug in and solve for w:
90=2w+2(15)
90=2w+30
60=2w
30=w
The width is 30.
(you could draw a diagram by labelling the two shorter sides 15 and the other sides w)
Hope this helps!!
Answer: y = -20x + 1
Step-by-step explanation:
The larger the m value is in y = mx + b is, the steeper the slope is.
