I believe the first quartile would be 24 and the third would be 8. Sorry if this wasn't correct. I haven't done this in a while.
Hope it helps
Answer:
Yes they are proportional because he is selling cars at the same rate
Step-by-step explanation:
Answer:
1.79553
Step-by-step explanation:
Step 1: Write expression
log₁₀(√(69.5² - 30.5²))
Step 2: Evaluate square root
log(√(4830.25 - 930.25))
log(√3900)
log(62.45)
Step 3: Find log
log₁₀ (or log)
log(62.45) = 1.79553
-------------------------------------
To use the table method. we find values that are easily evaluated by log₁₀
log₁₀(10) = 1
log₁₀(50) = 1.69897
log₁₀(100) = 2
So we know that log₁₀(62.45) is between 1 and 2 and greater that 1.69897.
You can divide 100 by 4 to find out how many lunches you can buy
or multiply 4 by the number of lunches you have had
100 - that number^=money remaining
Answer:
Now we can find the p value based in the alternative hypothesis and we got:
Step-by-step explanation:
Information given
represent the sample mean
represent the population standard deviation
sample size
represent the value to verify
z would represent the statistic
represent the p value
System of hypothesis
We want to verify if the true mean for this case is 64 or no, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
The statistic for this case is given by:
Now we can find the p value based in the alternative hypothesis and we got:
