Yup I found that the surface area is very brown
Answer:

Step-by-step explanation:
Use the following equation the find the slope:

Rise over run is the change in the y-axis over the change in the x-axis from one point to the other. This is also known as the "slope". Insert the known values:

Solve:

Simplify. Two negatives make a positive:

Simplify fraction by dividing top and bottom by 5:

The slope is 3.

It depends on what is being referred to by "this."
The description of the activity is that 10 drops are added twice and two readings are taken. If you do *that* 4 times, then a total of 20*4 = 80 drops will have been added.
If the activity referred to by "this" is the pair of acts {add 10 drops, read the volume}, then four repetitions will have added 10*4 = 40 drops.
Probably the expected interpretation is that "this" is {add 10 drops, read}, so 40 drops is likely the expected answer.
Answer:
z = - .5
Step-by-step explanation:
z = (x - μ)/ σ
z = 56 - 60/8 = -.5
g(x) = x^2 + 1(3x - 5)
<em><u>Replace all x's with 4.</u></em>
g(4) = 4^2 + 1(3 * 4 - 5)
g(4) = 16 + 1(12 - 5)
g(4) = 17(7)
g(4) = 119 (This is your answer.)
