I got -19/655 and i know for sure this isnt the correct answer.
Answer:
Roman
Step-by-step explanation:
An easy way to solve this is looking at whether the line has a positive or negative slope. We read graphs from left to right so <u>if the line is increasing from left to right, it has a positive slope while a line decreasing from left to right has a negative slope</u>. Since the line shown is decreasing from left to right, it will have a negative slope and Roman is the only one out of the two that shows a negative slope. To check to see if he's correct, we can check the y-intercept. The y-intercept of the line is 8 and Roman also has 8 written in the expression. Hence, meaning Roman is correct.
Best of Luck!
Answer:
The larger wheel is 10979.04098 more than the smaller wheel.
Step-by-step explanation:
Given that,
The circumference of the great wheel was twelve thousand and forty-one thousandth inches.
C = 12000.041 inches
The circumference of the lesser wheel was only one thousand twenty-one and two hundred-thousand inches.
C' = 1021.00002 inches
We need to find how much larger was the great wheel. To find it, take the difference of C and C'.
C-C' = 12000.041 inches - 1021.00002 inches
= 10979.04098 inches
Hence, the larger wheel is 10979.04098 more than the smaller wheel.
Answer:
We need a sample size of at least 719
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
How large a sample size is required to vary population mean within 0.30 seat of the sample mean with 95% confidence interval?
This is at least n, in which n is found when 
. So
Rouding up
We need a sample size of at least 719
