W=4N+10
N+4N+10=90
5N=80
N=80/5=16
Okay so the probability of drawing a blue bean is
8 / 29 = .276
29 is the total number of jelly beans
When we have replacement, we do not reduce the number of total jelly beans, so the probably of drawing blue stays the same.
But to find the probability of drawing a blue two times in a row, we must square the probability .
(.276) • (.276) = 0.076
Your answer is 7.6% !

Answer:
A 60m steel pole is cut back into 2 areas, in the ratio 11:4. at first, you upload the figures in the ratio, 11 and four, to be sure what the linked fee of one section equals. 11 + 4 = 15 60/15 = 4. So one section equals 4m. Substituting this back into the ratio, 11(4):4(4) 44m:16m The longer pole is 44m and the shorter one is 16m. the version between the two is 40 4 - sixteen = 28m The longer one is 28m longer than the shorter one. desire that helps. =D
