Answer:
where x denotes height of Allie
Step-by-step explanation:
An inequality compares two values. One value is less than, greater than, or not equal to another value.
Given: Allie is waiting to be tall enough to ride the thunder dragon roller coaster. You have to be at least 60 inches to ride.
To write: an equality
Solution:
Let the height of Allie be x inches.
As a person has to be at least 60 inches to ride,
the inequality can be
Answer:
C.
Step-by-step explanation:
It is linear because it have two variables (x and y) and the highest powers that they are raised to are 1
180 - 15w < $60
w = week
Subtract 180 from each side
-15w < -120
Divide each side by -15
w > 8
This means that the weeks have to be more than 8.
Let sin be a
3a^2-17a+10=o
A =5 or 2/3
Sin =5rej
Sun=2/3 = 41.8 or138
Answer:
The minimum score required for an interview is 73.4.
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:
If test scores are normally distributed, what is the minimum score required for an interview?
Top 25%, which is at least the 100-25 = 75th percentile, which is the value of X when Z has a pvalue of 0.75. So it is X when Z = 0.675.
The minimum score required for an interview is 73.4.
