Answer:

1: 2, 2: 3

Step-by-step explanation:

1 is 2 because if you count the total students, (25), divide by 2 to get 12.5 and round down. we want to find the 12th number. For the second one, do the similar thing, but now we have 13. Add the 13th and 14th numbers and divide by 2 to get 3.

Im not sure how to find the answer to this.

Brut [27]

BGH and GHD make a total of 180
a ratio of 2:3 means there are a total of 2+3=5 portion,
each portion is 180/5=36
so angle BGH is 36*2=72, and angle GHD is 36*3=108

the first-serve percentage of a tennis player in a match is normally distributed with a standard deviation of 4.3%. if a sample

miss Akunina [59]

It is now possible to find the margin of error, the reason being that the confidence level is not given. However the 'standard error' of the sample mean can be found as follows:
$Standard\ error=\frac{\sigma}{ \sqrt{n} }=\frac{0.043}{ \sqrt{15} }=0.011103$
Converted to a percentage, we get 1.11% which is the third choice of answer.
