Aresearcher computes the definitional formula for ss, and finds that σ(x − m) = 44. if this is a sample of 12 scores, then what would the value of sample variance be using the computational formula?
a. 3.7
b. 4.0
c. 44
d. not possible to know because the scores are not given

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees

you

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract
