The answer would be mercury.
2(sv) is the answer for the question
A) (12 ft)/(2 3/8 ft) = 5 1/19
The maximum height of a stack of boxes is 5 boxes.
b) (1/19)*(2 3/8 ft) = 1/8 ft is the room left at the top of the stack.
Take the number "of" divided by the other number then multiply it by 100% to get the percentage.
(21/33.5) ×100%= 62%
The probability of Erin not having a heart attack according to her family history would be 30%.
The probability of the test predicting correctly is 67%.
Therefore, the probability of the test correctly predicting that Erin will not have a heart attack would be (0.30)(0.67) = 0.201 or 20.1%.
