Answer:m<c=120
Step-by-step explanation:
You set the two expressions equal to each other solve for x and then plug in x to one expression to get the angle.
After that add the two angles together and subtract them from 360 divide by two and you’ll get the other two angles.
This usually only applies to parallelograms.
I hope this helps it’s been awhile since I’ve done this so if it sounds like gibberish I worked out the problem as a better explanation.
Answer:
11.70% probability that the mean outstanding credit balance exceeds $700
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution
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.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation
In this problem, we have that:
In an SRS of 100 couples, what is the probability that the mean outstanding credit balance exceeds $700?
This is 1 subtracted by the pvalue of Z when X = 700. So
By the Central Limit Theorem
has a pvalue of 0.8830
1 - 0.8830 = 0.1170
11.70% probability that the mean outstanding credit balance exceeds $700
