Answer:
Option D is correct.
Step-by-step explanation:
Option D is correct.
y < 2 and y >= x
Because the dotted line shows that y < 2 and y >=x is shown is represented by diagonal line.
Answer:
24% chance
Step-by-step explanation:
First, find the total number of graduates in the table, that number is 2610, that will be your numerator.
You will look at the table for the total number of students, that is 10730, that will be the denominator.
Now divide the smaller number/numerator (2610) by the larger number/denominator (10730)
= 0.2432432...
Then, multiply by 100 to get the percentage: 24.32432...%
Now, round to the nearest percentage: 24%
Therefore, f(c) = 3c+5
OPTION B is the correct answer
Answer:
4
Step-by-step explanation:
Answer:
A person must get an IQ score of at least 138.885 to qualify.
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:

(a). [7pts] What IQ score must a person get to qualify
Top 8%, so at least the 100-8 = 92th percentile.
Scores of X and higher, in which X is found when Z has a pvalue of 0.92. So X when Z = 1.405.
