The given inequality is
First we need to remove the absolute sign , and when we do so , we will get a compound inequality, that is
To solve for x, first we need to get rid of 10. and for that, we have to do subtraction
Now we need to get rid of 9, and for that, we do division
So the required solution is
Answer:
An we can use the normal standard table and the following difference and we got this result:
Step-by-step explanation:
Assuming this statement to complete the problem "with a standard deviation 5 mpg"
We have the following info given:
represent the mean
represent the deviation
We have a sample size of n = 54 and we want to find this probability:
And for this case since the sample size is large enough >30 we can apply the central limit theorem and then we can use this distribution:
And we can use the z score formula given by:
And replacing we got:
An we can use the normal standard table and the following difference and we got this result:
Answer:
Step-by-step explanation:
There aren't any factors that cancel (except 3x). The best you can do is multiply it out.
