Answer:

3/4

Step-by-step explanation:

To add fractions, they must have common denominators

convert them to common denominators

4/7 × 4/4 = 16/28

now their denominators are the same

16/28 + 5/28

add the numerators

16 + 5 = 21

21/28

Both the numerator and the denominator can be divided by 7

3/4 is the simplest form

Answer:

$-\left|7+3\right|$

Step-by-step explanation:

Solve each expression and then compare the results

case 1) we have

$15-\left|-5\right|\\ \\=15-(5)\\ \\=10$

case 2) we have

$\left|-4\right|+6\\ \\=(4)+6\\ \\=10$

case 3) we have

$-\left|7+3\right|\\ \\ =-(7+3)\\ \\=-10$

case 4) we have

$\left|-10\right|\\ \\ =-(10)\\ \\=10$

Determine the marginal distribution of Gender. In paragraph form, how you calculated the marginal distribution. Include your cal

Furkat [3]

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

$\mathrm{Pr}[G = g] = \begin{cases} \dfrac{379}{714} \approx 0.5308 & \text{if }g = \text{male} \\\\ \dfrac{335}{714} \approx 0.4692 & \text{if } g = \text{female} \\\\ 0 & \text{otherwise} \end{cases}$
