123 students each gave 2 cupid to each student in school there's 6 council how many cupid did they evenly make for the 123 student

each made 20.5

Step-by-step explanation:

123/6 = 20.5

The notation for the uniform distribution is X ~ U(a, b), where a = the lowest value and b = the highest value In your case, X ~ U(66,89) µ = (b+a)/2 Ď = (b-a)²/12 In this case, a = 66 and b = 89 Thus, µ = (89+66)/2 = 77.5 Ď = (89-66)²/12 = 44.0833 Then, because we now know the true/population µ and Ď, we can use z-scores. z = (X-µ)/Ď In our case, X = 71. So, Z = (X-µ)/Ď Z = (71-77.5)/44.0833 = -0.15 P(Z>-0.15) = P(Z<0.15) = 0.5596
