Suppose an article reported that 16% of unmarried couples in the united states are mixed racially or ethnically. consider the population consisting of all unmarried couples in the united states.
when n = 100, what is the probability that the proportion of couples in the sample who are racially or ethnically mixed will be greater than 0.17? (round the answer to four decimal places. type none if it is not appropriate to use the normal distribution.)

step-by-step explanation:

c) yes, because of asa or aas

the first option is the answer.

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
