Color-blindness is gender-based, with the majority of sufferers being males. roughly 8% of white males have some form of colorblindness, while the incidence among white females is only 1%. a random sample of 20 white males and 40 white females was chosen. let x be the number of males (out of the 20) who are color-blind. let y be the number of females (out of the 40) who are color-blind. let z be the total number of color-blind individuals in the sample (males and females together). which of the following is true about the random variables x, y, and z? x is binomial with n = 20 and p = .08. y is binomial with n = 40 and p = .01. z is not binomial. all of the above are true. only (a) and (b) are true.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
