Step-by-step explanation: When the a number is either added or subtracted on the inside (will be surrounded by parentheses if it is on the inside) the parent function is moved right and left. Since it is inside parentheses, though, everything that happens will be the opposite of what it shows. Even though it says -7, and you would assume it shifts left, it doesn't. It actually goes to the right.

Solve 6x + 8 = 2x + 11 Thanks

hammer [34]

The equation given in the question should be written down first and then the process should start for solving and finding the value of the unknown variable "x".
6x + 8 = 2x + 11
6x - 2x = 11 - 8
4x = 3
x = 3/4
The value of the unknown variable "x" comes out to be 3/4. I hope the procedure for solving this equation is clear enough for you to understand. In future you can always use this procedure to get to the solution of similar problems.

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

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

where G is a random variable taking on one of two values (male or female).
