0, 5/4
Step-by-step explanation:
If , you get 0=0, which is obviously true.

Answer:
To represent this operation as circles, we first graph what's in the parenthesis, which represents two circles with two circles each, that will give us the blur circle with 4 elements.
Then, each blue circle must be reproduced for times, because the expression 2x2 is multiplied by 4, giving as a result 16 circles in total. 4 groups containing 2 groups of 2 circles each.

Answer:
The 95% confidence interval for the difference in mean profile height and mean actual height of online daters is between 0.27 and 0.87 inches.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 30 - 1 = 29
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 29 degrees of freedom(y-axis) and a confidence level of . So we have T = 2.0452
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 0.57 - 0.3 = 0.27 inches.
The upper end of the interval is the sample mean added to M. So it is 0.57 + 0.3 = 0.87 inches.
The 95% confidence interval for the difference in mean profile height and mean actual height of online daters is between 0.27 and 0.87 inches.
