lindsey measures the length of 100 beetles and gets a mean of 2.56 inches with a standard deviation of 0.34 inches. She then realizes that her ruler was off and each measurement was 0.5 inches too long. Also, she decides it would have been better to measure in centimeters (2.54 cm = 1 in) because that is what scientists are supposed to do. If Lindsay takes each measurement and subtracts 0.5 inches and than multiplies by 2.54, what would the new mean and standard deviation be?

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
