Answer:
50% of the scores were above 75
Step-by-step explanation:
Problems of normally distributed(bell-shaped) 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:
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:
What percent of the scores were above 75?
This is 1 subtracted by the pvalue of Z when X = 75. So
has a pvalue of 0.5
1 - 0.5 = 0.5
50% of the scores were above 75
C) 30, 60, 90 because right off the bat, the largest angle is 90 degrees and it is the ONLY answer in which it’s other 2 angles are summed up to equal to it. And the rest of the facts match up. 60 degrees is twice as 30
The slope of the line is
It can be found from any two points that fall on a line by using the formula
2 is x or y from the second point and 1 is x or y from the first point
For example in that problem the first point is -2,0 and the second one is 0,3
Answer:
reagain and none that I know about the other day and none that I know that you are
Answer:
<h2>I think that is a FORMULA.</h2>
it can't be solved if we don't know the values of atleast one of the x and y.
Hope this helps.
Good luck ✅.
