Answer:
s = 2/3t
Step-by-step explanation:
For some time (t) in minutes, Sarah can iron "s" shirts:
s = (12/18)t
s = 2/3t
_____
If you need to, you can start with a proportion:
shirts/minutes = s/t = 12/18
Then multiply by t to get the above equation.
Answer:
The first choice is correct. ii only.
Step-by-step explanation:
A rigid transformation changes the location of the shape without changing its size. There are three basic rigid transformations: reflections, rotations, and translations.
We are given these properties:
i. Increases or decreases the size of the figure
ii. Moves the location of the figure.
iii. Changes the shape of the figure.
Let's analyze each choice below:
O ii only
. This is true. The other two properties are non-rigid transformations. Correct
O i and ii
. This is not true. Increasing or decreasing the size of the figure is a non-rigid transformation. Incorrect.
O ii and iii. Changing the shape of the figure is a non-rigid transformation. Incorrect.
O i, ii, and iii. Properties i and iii are non-rigid transformation. Incorrect.
If you add 167 + 49 that = 216 then you just have the add 7 to 216 which = 223.
so your answer is 223
The answer will be 43. i hope this helps you out! :)
I assumed that 3 households are sampled.
Now, is the number in each of these households equal to 1, 3 and 8 people?
Next, the question says, samples of n=2 are randomly selected (with replacement) from these 3.
So are sample space is
11
13
31
33
18
81
38
88
83
88
This is done 9 times.
Is that how you understand the problem?
When they select the household with only 1 person, the variance is 0
When they select the household with 8 people, they variance will be from a discrete uniform distribution
Similarly for household with 3 individuals.
