Answer: σ: 2.76

Step-by-step explanation:

Count, N: 5

Variance, σ2: 7.6

Steps

look at attached pic for formula

σ^2 = $\frac{Σ(xi - μ)^{2} }{N}$

$\frac{(21 - 25)2 + ... + (29 - 25)2}{5}$

⇒ $\frac{38}{5}$

⇒ 7.6

σ = $\sqrt{7.6}$

⇒ 2.756809750418

⇒ or 2.76

Tami spins a spinner with 7 sections. The sections are numbered 1 through 7 and all sections are the same size

dexar [7]

Answer:

1 / 7

Step-by-step explanation:

Number of sections on spinner = 7

Section is numbered 1 to 7

Since the probability of landing on each section is the same:

Probability that spinner lands on 4 :

Probability, p = Required outcome / Total possible outcomes

Required outcome = landing on 4 = 1

Total possible outcomes = (1 to 7) = 7

P(landing on 4) = 1 /7
