Well, do you know what 12+1 is? Because if she ended with 12 and ate 1 to begin with, you just add those numbers together, and that is your answer!
The ratio of nonwinners in group A to nonwinners in group B after the selections are made is 156 : 319.
<h3>What is the ratio?</h3>
Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).
Nonwinners in group A = (1 - 3/5) x 390 = 156
Winners in group B = (390 - 156) = 234
nonwinners in group B = 553 - 234 = 319
The ratio = 156 : 319

X = (22-10)/6 = 12/6 = 2 miles
Cos (Ф) = 0.9123
To calculate Ф, we have to find the arcos (0.9123) ≈ cos⁻¹ (0.9123)
cos⁻¹(0.9123) = Ф
cos⁻¹ (0.9123) = 24°.175
Ф = 24°.175
