Please help, no link or scams Describe the center and spread of the data using the more appropriate statistics, either
the mean and standard deviation or the five-number summary.
{1, 12, 2, 9, 2, 3, 7, 3, 3, 6}
F mean = 4.8; standard deviation ≈ 3.4
G mean = 4.8; standard deviation ≈ 3.6
H median = 3; range: 1–12; interquartile range: 2-7
J median = 3; range: 2–7; interquartile range: 1-12

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

y -5 = (-1/4)(x + 8)

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

answer: group b.
