30. items produced by a manufacturing process are supposed to weigh 90 grams. the manufacturing process is
such, however, that there is variability in the items produced and they do not all weigh exactly 90 grams. the
distribution of weights can be approximated by a normal distribution with mean 90 grams and a standard
deviation of 1 gram. about what percentage of the items will either weigh less than 87 grams or more than
93 grams?
a 0.15%
b. 0.3%
c. 6%
d. 94%
e. 99.7%

Using elimination, what is -4x+2y=-12 4x+8y=-24

If the tip varies directly with the number of guest which equation represents between the tip,t, and the number of guest,g?

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
