Answer:






Step-by-step explanation:
We are given the following in the question:

We have to find the growth rate z(t) in each of the following cases:
(a) z = xy

(b) z=x/y

(c) z=y/x

(d) z=x^(1/2) y^(1/2)

(e) z=(x/y)^2

(f) z=x^(-1/3)y^(2/3)

Linear equations are represented by straight line.
The required graph is graph (a).
The given parameters are:

Let x represents the number of weeks, and y represents the number of words in week x.
So, we have:

Substitute 15 for Rate


The above equation means that:

The graph that represents the above ordered pair is graph (a).

6 = 3(x - 2)
6 = 3x - 6
3x = 12, x = 4
Solution: D
Answer:
1/8
Step-by-step explanation:
This is actually pretty easy.
First, you have the sample of the children.
You know that the family with 3 children, can only have the following children:
MMM: all males
MMF: 2 males, 1 female
MFF: 1 male, 2 females
MFM: 2 males, 1 female (different order)
FMM: 1 female, 2 males
FFM: 2 females, 1 male
FMF: 2 females, 1 male
FFF: 3 females
If you count all of these possibilities, we have 8 possible cases of family with the childrens.
In only one of them, we have only females and no males, which is the last one, all 3 females.
Therefore, the probability to select a family with no male, is only 1/8.
