Answer: 14.48000 . . . ≤ t < 15.0000
Step-by-step explanation:
"Truncated by a hundreths of a second" means that the time was rounded to the nearest 0.0X second. That would mean the reported time of 14.48 seconds was shortened from a time period having more digits to the right. For example, If the time were actually 14.48223 seconds, the time was truncated to just 14.48 seconds. The term used here. truncated, means that the digits after the hunredth place are simply dropped. It doesn't say rounded, just truncated. Brutal. So that would mean that times between 14.48000 . . . and 14.48999 . . . would all be reported as 14.48 seconds.
So the time could actually be 14.48000 . . . ≤ t < 15.0000
B is the answer i had this on my test the other day
AB and WX because the length is directly the same
so we know that 24% of the students buy their lunch at the cafeteria, and 190 students brownbag.
well, 100% - 24% = 76%, so the remainder of the students, the one that is not part of the 24% is 76%, and we know that's 190 of them.
since 190 is 76%, how much is the 24%?
![\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 190&76\\ x&24 \end{array}\implies \cfrac{190}{x}=\cfrac{76}{24}\implies 4560=76x \\\\\\ \cfrac{4560}{76}=x\implies 60=x \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{total amount of students}}{190+60\implies 250}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20amount%26%5C%25%5C%5C%20%5Ccline%7B1-2%7D%20190%2676%5C%5C%20x%2624%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B190%7D%7Bx%7D%3D%5Ccfrac%7B76%7D%7B24%7D%5Cimplies%204560%3D76x%20%5C%5C%5C%5C%5C%5C%20%5Ccfrac%7B4560%7D%7B76%7D%3Dx%5Cimplies%2060%3Dx%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20%5Cstackrel%7B%5Ctextit%7Btotal%20amount%20of%20students%7D%7D%7B190%2B60%5Cimplies%20250%7D)
