Do the Pythagorean theory to find the unknown side by doing:
c^2 = a^2 - b^2
Then you’ll have two sides and two angles.
Do sine law.
Sin(angle) / side (opposite to it) = Sin(angle) / side (opposite to it)
I’m working on the same thing in school! For number 2, what i would do is start by setting up the scatter plot by using the X and Y table and create origins to place on the graph. ( ex. (1,30) for your first one ). Also, remember to write in the laps completed and calories burned. Next, estimate a line that meets as many points as possible. ( I would use the completed scatter plot in number 3 for an example for how to draw the line ). And that’s all I can help you with :( I forgot how to do the equation part because I just started with this on Monday. Hope this helps!

Answer:
Mean of these n = 23 observations is 16.21 .
Step-by-step explanation:
We are given with the one‑sample t statistic from a sample of n = 23 observations for the two‑sided test of H0 : μ = 15 versus Hα : μ > 15 has the value t = 2.24 . Also, the standard deviation from the sample is 2.4.
So, Null Hypothesis,
:
= 15
Alternate Hypothesis,
:
> 15
The test statistics that is used here is One sample t-test statistics;
T.S. =
~ ![t_n_-_1](https://tex.z-dn.net/?f=t_n_-_1)
where,
= sample mean
= population mean = 15
s = sample standard deviation = 2.4
n = sample size = 23
So, test statistics =
~ ![t_2_2](https://tex.z-dn.net/?f=t_2_2)
2.24 =
1.21 =
- 15
= 1.21 + 15 = 16.21
Therefore, mean of n = 23 observations is 16.21 .
The exponent indicates how many times you multiply the base number by itself.
The answer is <u>143 miles.</u>
<h3>
EXPLANATION</h3>
The ratio between Dory's miles and Karly's miles is 11:1. This means that we need to <em>divide 156 by 12, </em>which is <u>13.</u>
Because Dory's miles make up 11/12 of the total miles, we need to take 1/12 (which is 13) from the 156 to get the final answer of <u>143 miles.</u>
