AnnZ [12381]
Thus, there are five distinct flavors. A group of 180 individuals was surveyed. Accordingly, the null hypothesis suggests no significant difference, with each flavor receiving 180/5 = 36 counts. x^2 = \sum{\frac{(x_i)^2}{m_i}}-n. Here, mi indicates the expected frequency based on the hypothesis, which is 36, n = 180, and xi corresponds to the actual observations. By substituting the known values, we find that x^2 = 9. The level of association is expressed as \sqrt{X^2}/ \sqrt{N(n-1)}. This results in approximately 0.10, which surpasses our threshold.

"The difference between five-halves of a number<br> and 17 is 48."
Inessa [12570]
Let the number be x. The equation x/5 - 17 = 48 leads to (x - 85)/5 = 48. Multiplying gives x - 85 = 240, so x = 240 + 85, resulting in x = 325.
