Answer:
A. 133 degrees
Step-by-step explanation:
You add the two known interior numbers in the triangle to find the unknown exterior variable. In this case, the two known interior numbers are 83 and 50. 83 + 50 = 133
To answer this you need to read the stem and leaf lot and determine how many values were over 28., Or how many were less than or at 28 and subtract it from 30.
There are 10 teams at 28 or less, so 20 teams are above 28.
The number to the left of the | tells us the tens place of the set of number that come after it.
For example 2|4 7 8 stands for 24, 27, and 28.
If 20 out of 30 were above 28 homeruns, then your probability is 20/30 or 2/3 or 0.667.
Answer:
0.35% of students from this school earn scores that satisfy the admission requirement.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be 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.
The combined SAT scores for the students at a local high school are normally distributed with a mean of 1479 and a standard deviation of 302.
This means that 
The local college includes a minimum score of 2294 in its admission requirements. What percentage of students from this school earn scores that satisfy the admission requirement?
The proportion is 1 subtracted by the pvalue of Z when X = 2294. So



has a pvalue of 0.9965
1 - 0.9965 = 0.0035
0.0035*100% = 0.35%
0.35% of students from this school earn scores that satisfy the admission requirement.
Answer:
B
Step-by-step explanation:
When you double the dimensions of a triangle, the area is four times as large, so if you quadruple it, it would be 16 times as large
