Answer:
76 percent done.
Step-by-step explanation:
Reasoning for this if its 76/100 you know that it will be 76. Or im Just got confused.
2 3/4 + 1 3/8 = 4.125 and there is your answer
5T < 10,000 lb
16T > 6,400 lb
A median is 65 inches and a standard deviation is 1.7:
a. 65 + 1 SD = 65 + 1.7 = 66.7 in
It means that there are : 100% - ( 50% + 34% ) = 100% - 84% = 16% students taller than 66.7 inches.
b. Heights between 61.6 in and 68.7 in are within 2 standard deviations:
13.5% + 34% + 13.5% + 34% = 95%
0.95 * 300 = 285
There are 285 students between 61.6 in and 68.7 in tall.
