ergei wants to prove that Triangle A B C is similar to Triangle F G H. On a coordinate plane, triangle A B C has points (1, 1),

(3, 3), (3, 1). Triangle F G H has points (4, 4), (12, 12), (12, 4). Which would help him prove that? Check all that apply. Measure angles A and F to show they are congruent. Measure angles F and G to show they are congruent. Use the right angle marks to show that angles C and H are congruent. Use the grid or a ruler to show that A B = F G, B C = F G, and A C = F H. Use the grid or a ruler to show that StartFraction F G Over A B EndFraction = StartFraction G H Over B C EndFraction = StartFraction F H Over A C EndFraction.

Find the range, mean, and standard deviation of the data set (3, 6, 9, 11, 15, 16) The range is 13 (Type a whole number.) The me
iris [78.8K]

Answer: The range is 13.  The mean is 10. The standard deviation is 4.62 .

Step-by-step explanation:

The given data : 3, 6, 9, 11, 15, 16

Total number of data values : n = 6

The mean of data is given by :-

\overline{x}=\dfrac{\sum^6_{i=1}x_i}{n}\\\\\Rightarrow\overline{x}=\dfrac{60}{6}=10

The standard deviation is given by :-

\sqrt{\dfrac{1}{n}(\sum^6_{i=1}(x_i-\overline{x})^2)}\\\\=\sqrt{\dfrac{1}{6}(\sum^6_{i=1}(x_i-10)^2)}\\\\=\sqrt{\dfrac{1}{6}\times(49+16+1+1+25+36)}=4.61880215352\approx4.62

The range of the data : Maximum value -Minimum value
