Answer:
a) 18.98%
b) -0.2142
c) (183000,407000)
d) (127000,463000)
Step-by-step explanation:
We are given the following in the question:
Mean, μ = $295,000
Standard Deviation, σ = $56,000
a) Coefficient of variation
b) z-score
x = $283,000
Formula:
Putting the value, we get,
c) 95% interval
Empirical Rule:
- According to this rule almost all the data lies within three standard deviation of mean for a normal distribution.
- About 68% of data lies within one standard deviation of mean.
- About 95% of data lies within two standard deviation of mean.
Thus, the price of 95% of the homes lies between $183,000 and $407,000.
d) 90% interval
Chebyshev's Rule:
- For a non normal data atleast percent of data lies within k standard deviation of mean.
- For k = 3
Thus, 90% of prices will lies within three standard deviation of mean.
According to Chebyshev's Theorem 90% of prices will lie between $127,000 and $463,000.
I'm not too sure but I think it's option
1. No, because only one angle of the triangle is congruent.
Answer:
3:8 3 sodas for 8 drinks
Step-by-step explanation:

3/8
So pythagrorean theorem is the ideal way and easiest way to solve this
a^2+b^2=c^2
8.5^2+11^2=x^2
72.25+121=193.25
square root of 193.25=13.9014 or 13.9 in
9.5^2+15^2=x^2
90.25+225=315.25
square root of 315.25=17.7553 or 17.8 ft
