Daniel [21]

Mary worked 22 hours.

To solve first you would subtract the amount she made in tips from her total earnings (317-185)
= 132
Then you divide that answer by her hourly salary of $6 (132/6)

$\bf ~~~~~~~~~~~~\textit{middle point of 2 points }

PLSSSSSSSSSSSSSSSSSSS HELPPPPPPPPPPPPPPPPPPP!!!!GUARaNTEE REWARDAmanda earned a score of 940 on a national achievement test that

MrMuchimi

To solve this question, you¨ll need to use a table of the standardized Normal distribution, or you could use a graphing calculator. The answer will be the cumulative property which will be a number with decimals. However, this represents the students who had a lower score then her, You´ll need to subtract this from 1 in order to get the opposite number, which will be the kids who scored higher. Be sure to multiply the result by 100 to get a percentage. Your answer should be 0.806 hope this helped!
