Sorry.....67.33  inches

Mrs. Hall records the heights of 50 students in a spreadsheet. The mean height is 68 inches. After looking at the data again, she realized that two of the 50 observations were outliers that must have been typos, 82 and 86 inches. She deleted these two observations. What is the new mean, rounded to the nearest hundredth? show work

To get the new mean, we have :

 [ 50(68) - 82 - 86] / 48 =  67.33

No way to tell since we don't know what f(x) is......

Not quite, HelpMeWithThisPlease.....but....good try.....

Going from

2^(2x+2)=64  equate  bases

2^(2x + 2)  = 2^6   solve for the exponents

2x+ 2  = 6      divide through by 2

x + 1  = 3   →   x  = 2

The nth term is given by :

a_n  =  -17 + 7 (n - 1)

Sum of 1st 17 terms  ??? 

S₁₇  =  7(1 - 2^17 ) / ( 1 - 2)  =  917,497

Good job....!!!

M = 66 + 6.3w + 12.7h − 6.8a   for  M { w, h, a }  =  { 136, 72, 16 } =

66 + 6.3(136) + 12.7(72) - 6.8(16)    =  1728.4   cal

4cos^2ϴ = 0  divide both sides by 4

cos^2ϴ = 0    take the sq rt of both sides

cosϴ = 0     at   90°  and 270°
