Lets take 6/9. 9 is a multiple of 27, multiply 9 times 3 for a denominator of 27. Whatever we to do the bottom, we do to the top. So multiply 6 by 3 as well for numerator of 18. This gives us our answer, 18/27.
The ratio of shots made to shots took is 6:10
Answer:
The 95% confidence interval for the population mean height of males of this country is between 67.136 inches and 74.864 inches.
Step-by-step explanation:
For the country, we only have the standard deviation of the sample, so we use the t distribution to build the confidence interval.
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 = 45 - 1 = 44
Now, we have to find a value of T, which is found looking at the t table, with 44 degrees of freedom(y-axis) and a confidence level of 0.95(). So we have T = 1.68
The margin of error is:
M = T*s = 1.68*2.3 = 3.864
In which s is the standard deviation of the sample. So
The lower end of the interval is the sample mean subtracted by M. So it is 71 - 3.864 = 67.136 inches
The upper end of the interval is the sample mean added to M. So it is 71 + 3.864 = 74.864 inches
The 95% confidence interval for the population mean height of males of this country is between 67.136 inches and 74.864 inches.
The answer is B bc 8 time is the radius squared times pi
So 15% is out of 100%, and the cab company has sent 30 cabs out of x?(x is the total number of cabs).
So, by setting up that data we already know, we can make this equation to figure out how many cabs total the company actually has:
<span>15x = 100 * 30
</span>
We do the multiplication on the right side
15x = 3000
And divide to isolate the "X" variable
x = 200
So, the cab company has 200 cabs total, and they sent out 30 of them.
