Corresponding sides of similar shapes or figures are proportional to each other. Since ∆LMN ~ ∆OPQ, the ratio of their corresponding sides would therefore be equal. Thus:
Since the data is insufficient. Let us denote that n1 = 100, n2 = 100X1 = 38. X2 = 40 So looking for the p value: p = (38+ 40) / (100 + 100) = 0.39 z = (38/100 - 40/100)/√ (0.39*(1-0.39)*(1/100 + 1/100))= -0.2899 P-value = P (|z| > 0.2899) = 0.7718
No, because if you work with fraction and do (3 eggs for every 2 cups) then you would be multiplying 3x4 and now you have tot do that to the demominator so she would need 8 cups of sugar
