Answer:
d(t) = 60t
Step-by-step explanation:
When d = 0, t = 0 as well, so the y-intercept in 0. The slope of the line would be 60.
Hope this helps!
Answer:
For a normal distribution 68% of data falls within one standard deviation from mean on both sides of mean
Step-by-step explanation:
A normal distribution's graph is a bell shaped curve that is completely described by its mean and standard deviation. Standard deviation is measured in terms of distance from mean.
34% of data is covered in one standard deviation from mean on one side.
Therefore, for a normal distribution 68% of data falls within one standard deviation from mean on both sides of mean ..
Answer:
Step-by-step explanation:
If you are looking for a missing angle measure, you use the 2nd button and the cos button. Make sure, first off, that your calculator is in "degree" mode by hitting the "mode" button and making sure that the "degree" is highlighed and not the "radian". Then hit "clear". Once you know that you are in the correct mode, hit "2nd" then "cos" and you will see this on your screen:

Inside the parenthesis you will enter your decimal, so it looks like this now:

You do NOT have to close the parenthesis, but you can if you want to. Then hit "enter" to get that the angle that has a cosine of .7431 is 42.0038314 or, to the nearest degree, 42
You would subtract 15 on both sides and then you would have 2x=-14 then you divide both sides by 2 and x would equal -7
