A large set was collected and analyzed for the U. S. college population based on college majors. From the scatter plots produced, the following associations were observed. The linear model p = 2,376t + 73,219 can be used to estimate the number of college seniors p who graduated with a bachelor's degree in psychology t years after 2000. The equation b = 2,414t + 56,545 models the number of college seniors b who graduated with a bachelor's degree in biology t years after 2000.

4 and 5)16.97 or 12√2

< 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)

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
