Answer:

10 $\frac{1}{2}$

Step-by-step explanation:

to multiply, convert each fraction into an improper fraction. you do that by multiplying the denominator by the whole number and adding the numerator. so 3 $\frac{3}{4}$ will be $\frac{15}{4}$ and 2 $\frac{4}{5}$ will be $\frac{14}{5}$ . now you multiply the numerator by the numerator and the denominator by the denominator. your fraction will be $\frac{210}{20}$ . to simplify, you divide 210 by 20 and you will get 10 $\frac{1}{2}$ :)

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).

Canada Olympic Park features sports training and entertainment facilities.The monster Zip line produces average speed of 120 kil

alexgriva [62]

The first thing you should do in this case is to represent the distance of "the monster Zip line" by a function.
The function for this case is:
D = 120h
Where,
D: distance in kilometers.
h: time in hour.
Substituting the values we have:
D = 120 * (0.25) = 30 Km
answer:
You could travel on the Monster Zip line 30 Km in 0.25 hours
