Match each number in scientific notation with the number written in standard form. (3 points)
6.82 x 107 0.682
6.82 x 10-6 6,820,000
6.82 x 106 68,200,000

25. apply the properties of integer exponents to identify all of the expressions equivalent to 18. (3 points)
a) 2-3

b) 23

c) 123

d) 22x 2-5

e) 2-2x 25

the number 23 is an irrational number because the square root of 23 is 4.795831523…. explain why this is not a true statement. (3 points)

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
