I do not know sorry I think I do do not know sorry
Let's call :
x=the number of downloaded standard version
y= the number of downloaded high-quality version
We have : -the high-quality version was downloaded three times as often as the
standard version => 3x=y
-standard version is 2.8 megabytes .the high-quality version is 4.6
MB.The total size downloaded for the two versions was 4482 MB
=> 2.8x+4.6y=4482
Solve for x,y
x=270 , y=810
Answer: The maximal margin of error is 4.822.
Step-by-step explanation:
Since we have given that
Number of bags = 38
Sample mean = 78 ounces
Standard deviation = 14.5 ounces
At 96% confidence interval for the true population mean bags of nut weight.
So, z = 2.05
As we know that formula for "Margin of error":

Hence, the maximal margin of error is 4.822.
Constant of proportionality is the same as the slope. So find two points on the line and then calculate the slope using rise/run
For this one, you should get 3
Percent means parts out of 100
140%=140/100=14/10=1.4/1=1.4
1.4>0.14
140% is bigger
