2 x 32
4 x16
8 x 8 m
are all possible
520 is 2 standard deviations below the mean (600-520)/40=2
2 standard deviations below the mean for second tes would be 400- 2(40)=320
No ......it would be +144 (though that is incorrect number)
216-12= 204
Time drivin = 3 2/3 hr
average = 165/(3 2/3) mph =......
5xy +. (13x+x). + (-8+2)
5xy + 14x -6 Or. x(5y+14)-6
Agreed.... not really much fun any longer.....just repetitive homework Q's looking only for 'answers'. Rarely does anyone f/u with a 'thanx' or wanting more info..... too bad..
.. I am almost gone as are others....
Hour hand moves .5 degree per minute and starts at 270 degrees at nine o'clock
So hour hand is at. 270 + (20*.5)= 280o
Minute hand is at 120 degrees at 20 after
280-120=160o between the hands....
D= daught age now. 10 years ago. D-10. And mother was M-10= 7 (D-10)
NOW. M= 2D. Sub this into the fjest equation
2D - 10 = 7D-70
60=5D. D = 12.
Then M = 2D= 24. ( Mom was preggo @ 11 y/o ! )
The RDA is the recommended daily allowance of the vitamin. If you get more than this amount it is more than 100% of the RDA....
The angle that has tan = a/b. (Remember tan= opp/adj) Is the angle at the lower right....cos of this angle would be adj/ hyp =b/ ((sqrta2+b2))
