Answer:
y = 10
Step-by-step explanation:
<u>Since all sides are equal, that means all angles are 60 degrees. 60 + 60 + 60 = 180</u>
<u />
5y + 10 - 10 = 60 - 10
5y / 5 = 50 / 5
y = 10
Answer: y = 10
Just scan it, there’s an answer for it already I’m pretty sure
You can do:
16 - 10 and then + 1 (thats 7)
9+ ? is 16 ? ( 7)
Answer:
Top 3%: 4.934 cm
Bottom 3%: 4.746 cm
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:

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:

Top 3%
Value of Z when Z has a pvalue of 1 - 0.03 = 0.97. So X when Z = 1.88.




Bottom 3%
Value of Z when Z has a pvalue of 0.03. So X when Z = -1.88.




The square root of 63 is about 7.9, which is between 7 and 8
