To decrease something at 100% by 7% is:
100% - 7% = 93%
You multiply the original value by 0.93 to decrease it from it's original value by 7%
The marginal distribution for gender tells you the probability that a randomly selected person taken from this sample is either male or female, regardless of their blood type.
In this case, we have total sample size of 714 people. Of these, 379 are male and 335 are female. Then the marginal probability mass function would be
![\mathrm{Pr}[G = g] = \begin{cases} \dfrac{379}{714} \approx 0.5308 & \text{if }g = \text{male} \\\\ \dfrac{335}{714} \approx 0.4692 & \text{if } g = \text{female} \\\\ 0 & \text{otherwise} \end{cases}](https://tex.z-dn.net/?f=%5Cmathrm%7BPr%7D%5BG%20%3D%20g%5D%20%3D%20%5Cbegin%7Bcases%7D%20%5Cdfrac%7B379%7D%7B714%7D%20%5Capprox%200.5308%20%26%20%5Ctext%7Bif%20%7Dg%20%3D%20%5Ctext%7Bmale%7D%20%5C%5C%5C%5C%20%5Cdfrac%7B335%7D%7B714%7D%20%5Capprox%200.4692%20%26%20%5Ctext%7Bif%20%7D%20g%20%3D%20%5Ctext%7Bfemale%7D%20%5C%5C%5C%5C%200%20%26%20%5Ctext%7Botherwise%7D%20%5Cend%7Bcases%7D)
where G is a random variable taking on one of two values (male or female).
Answer:
3 1/4
Step-by-step explanation:
You can do a equation:
133x=432 1/4
Which would give you 3.25 but in fraction form it is 3 1/4
Hope this helped!
Answer:
105 11/12
Step-by-step explanation:
With mixed numbers you can also write them as functions so 5 11/12 could also be written as 5+11/12.
Once you have rewritten the mixed number it's simply a matter of addition: 100+5+11/12
X= -3
-3+-3=-6 +1= -5 and there are 5 red squares
