Answer:
Step-by-step explanation:
<u>According to the question we have:</u>
- Formula h = - 16t + s
- h = 0
- s = 555.427 ft
- t = ?
<u>Substitute the given values and solve for t:</u>
- 0 = - 16t + 555.427
- 16t = 555.427
- t = 555.427/16
- t = 34.714
Answer:
-8
Step-by-step explanation:
3+8+8-2=17
7+4+5+1=17
10+12+3+x=17
x=17-25
=-8
Answer:

Step-by-step explanation:
A bisector is the line that divides an angle (which in this case is
) exactly in half. Therefore,
and as such we can solve for
:

and we are done.

Answer:
The minimum score required for an A grade is 88.
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:

Find the minimum score required for an A grade.
Top 12%, which is at least the 100-12 = 88th percentile, which is the value of X when Z has a pvalue of 0.88. So it is X when Z = 1.175.




Rounding to the nearest whole number
The minimum score required for an A grade is 88.
