Answer:
Well the answer to the first half of the question is 9.6 so.. 13 would be greater than that. :/
Step-by-step explanation:
Answer:the unknown leg is 7.5
Step-by-step explanation:
The given right angle triangle has a hypotenuse, a known leg and an unknown leg.
From the triangle,
The hypotenuse is 9
The known leg is 5
The unknown leg is x
The formula for Pythagoras theorem is expressed as
Hypotenuse^2 = opposite side^2 + adjacent side^2
Hypotenuse^2 = known leg^2 + unknown leg^2
Therefore
9^2 = 5^2 + x^2
81 = 25 + x^2
x^2 = 81 - 25 = 56
x = √56 = 7.5
Median is the central tendency of the data and always exists in the middle of the data set.
<h3>What is the median?</h3>
The Median is the middlemost value of the numbers arranged in the ascending orders. Median is the central tendency of the data and always exists in the middle of the data set.
The process of finding the median if the number of data points is even is as follows:
- Put the numbers or the data points in the order(increasing or decreasing i.e. ascending or descending order)
- Next cross of the high/ low pairs
- Add the leftover numbers
- and divide the number( as obtained in the above step by 2)
( if the number of data pints were even then we just need to arrange the numbers and cross the high/low pair and only one data point will be left which acts as the Median of the data set)

Answer:
The standard deviation for the sample mean distribution is 
Step-by-step explanation:
The central limit theorem states that if you have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population then the distribution of the sample means will be approximately normally distributed.
For the random samples we take from the population, we can compute the standard deviation of the sample means:
From the information given
The standard deviation σ = 136 dollars
The sample n = 45
Thus,
The standard deviation for the sample mean distribution is
