Abag contains 15 marbles. the probability of randomly selecting a green marble is 5. the probability of rand
green marble, replacing it, and then randomly selecting a blue marble is 75. how many blue marbles are int

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

none cuz there are no "following statements" regarding the question

step-by-step explanation:

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
