(b) Team batting averages for major league baseball in 2005 are represented below. Find the variance and standard deviation for each league. Calculate standard deviation and compare the results. NL Frequency AL Frequency
0.252-0.256 4 0.256-0.261 2
0.257-0.261 6 0.262-0.267 5
0.262-0.266 1 0.268-0.273 4
0.267-0.271 4 0.274-0.279 2
0.272-0.276 1 0.280-0.285 1

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
