NO LINKS OR ELSE YOU'LL BE REPORTED! Only answer if you're very good at Math. No guessing please. On a quiz there are four multiple - choice questions worth 3 points and two true/ false questions worth 1 point each. Each multiple - choice question has five possible choices. If a student randomly guesses on each question, what is the expected value of the student's score on the test?

A: 1.8

B: 3.4

C: 5.4

D: 2.8
​

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

< 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)
