Answer:
Minimum: $25,200
Maximum: $44,800
Step-by-step explanation:
When the distribution is normal, we use 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 question:
What are the minimum and the maximum starting salaries of the middle 95% of the graduates
Minimum: 50 - (95/2) = 2.5th percentile.
Maximum: 50 + (95/2) = 97.5th percentile
2.5th percentile:
X when Z has a pvalue of 0.025. So X when Z = -1.96.
The minimum is $25,200
97.5th percentile:
X when Z has a pvalue of 0.975. So X when Z = 1.96.
The maximum is $44,800
Answer:
$614.62
Step-by-step explanation:
The monthly payment is calculated using the formula:
where:
- M= monthly payments
- P= the amount borrowed
- r= annual interest rate
- n=total number of monthly payments.
Given the amount borrowed is $7,000, r=9.75% and n=1*12=12 months, the monthly payments can be calculated as:
Hence, the monthly payments are $614.62
The pattern is times 4, minus 2. So, 22 x 4 = 88-6 = 86, then 86 x 4 = 344-2 = 342
So,
1, 2, 6, 22, 86, 342 is your answer
I am not sure, but i think its root of 3 bcs tan of the angle given is the slope
