Find the variance and standard deviation of the given set of data to the nearest tenth. {530, 150, 320, 500, 200, 690, 770}

1) variance = 48,326.5, standard deviation = 219.8

2) variance = 56,381, standard deviation = 237.4

3) variance = 219.8, standard deviation = 48,326.5

4) variance = 48,326.5, standard deviation = 24,163.3

a) 15/7

step-by-step explanation:

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

r and t.

both are 64 degrees.
