Answer:
I’M GONNA GO WITH (B) BECAUSE IF YOU WERE TO DO IT ON A GRID YOU WOULD MARK IT (X,Y) SND THEN DO THE MATH FROM THER
Step-by-step explanation:
HOPE I COULD HELP✌
Degree is the highest power of the polinomail
since higest poer is p^3, 3 is higest poer=degree
3rd degree

By the way, I'm doing the same exam for Geometry as well. There's a lot of proof questions on there which I'm not good at doing for the reasoning part. If you finish the exam before I do, maybe you can message me what the answers are for some of the questions on there so I know if my answers for the questions are incorrect or not.
Besides that, hope the answer above is correct for you.

Answer:
Approximately 6 observations are more than 74
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
![\mu = 50, \sigma = 12](https://tex.z-dn.net/?f=%5Cmu%20%3D%2050%2C%20%5Csigma%20%3D%2012)
Approximately how many observations are more than 74?
First step is finding the percentage of observations which are higher than 74, which is 1 subtracted by the pvalue of Z when X = 74. So
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![Z = \frac{74 - 50}{12}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B74%20-%2050%7D%7B12%7D)
![Z = 2](https://tex.z-dn.net/?f=Z%20%3D%202)
has a pvalue of 0.9772
1 - 0.9772 = 0.0228
Out of 250
0.0228*250 = 5.7
Approximately 6 observations are more than 74
