If the variance is 34 kg2 what is the standard deviation?

Standard deviation = 5.831 Kg.

Step-by-step explanation:

We are given that variance is 34 .

Standard deviation formula =

                                           = = 5.831 Kg .

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

y=mx+b

step-by-step explanation:

m slope, b y-intercept
