Answer:17.3964 males 7.6035 females
Step-by-step explanation:
The first way to calculate the expected uses the marginal percentages. If sex is not related to flavor preference, you would expect the same percentages of males to prefer the same flavors as females. Since overall 20.71% prefer vanilla, you would expect 20.71% of males to prefer vanilla. Now, 20.71% of 84 people is 17.3964, so this is how many males you would expect to prefer vanilla. You would also expect 20.71% of the females to prefer vanilla, which is 17.6035. So you'd expect 17.3964 males and 17.6035 females to prefer vanilla.
So 3x=6+4y
divide both of the equations by 3
x=2+4y÷3
x=2+4/3 y
your answer
x=2+4/3 y hope this will help
I just wrote the answer on paper as it would’ve been too confusing just typing it
When we have exponents like such (x^-6)^-2 , the numbers are multiplying, so we have x^12, then we take that value and, because it is dividing with the same base, we substract the numbers, so x^12-(-4) = x^16.
I got -5 & 2/5 because
2/3x and 3/5 can be made into
20/30x and 18/30
And then by adding 2 to -2
And adding 2 to 4
The equation becomes
20/30x + 6 = 18/30
Then I subtracted 6 from 18/30 and got
20/30x = -5 & 2/5
Then simplified that to
2/3x = -5 & 2/5
That's just what I think you should do.
