Each bag of cereal should contain 350 grams. A box was selected at random and weighed 342 grams. What is the percent error?

Hover for more information. In the given question, the accepted value is 350 grams; the experimental value is 342 grams. Therefore, the percentage error is % = % = 2.286% (to three decimal places). ... Therefore, the percentage error is 0.02286 x 100% = 2.286%.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
