Answer:
A) reduction
Step-by-step explanation:
The arrow goes from the original object to the dilated object. The dilated object is smaller than the original object, so the dilation is a reduction.
Answer: A) reduction
Answer:
These questions focus on how the proportion of females will vary in random samples if we assume that 0.60 of the population of part-time college students is female.
1. Before we use a simulation to simulate the selection of random samples from this population, let’s make sure we are clear about who is in the population. For this situation which statement best describes the population? part-time college students
2. What are we assuming to be true about the population? The proportion of the population that is female is 0.60
3. Which of the following sequences of sample proportions is the most likely to occur in random samples of 25 students from this population? 0.56, 0.60, 0.44, 0.68, 0.76
Answer:
2

5
Step-by-step explanation:
Start by multiplying 2 and -4/5 as fractions
2 -4 -8
------ x ------ = -------
1 5 5
Then multiply 6 and 1/3 as fractions
6 1 6 2
------ x ------ = ------- = -----
1 3 3 1
Lastly,add the two results after converting 2/1 to 10/5 to use the Greatest Common Factor so you can add.
-8 10 2
------- + ------ = -------
5 5 5
f(2)=36
Basically, the x becomes two so it changes to six squared
Answer:
The percentage of inter-rater reliability is 80%.
Step-by-step explanation:
The rate of inter-rater reliability is the division of the number of intervals in which they agreed number of total intervals.
In this problem, we have that:
There are 10 intervals.
The observers agreed on 8 of them.
So the rate of agreement is 8/10 = 0.8.
As a percentage, we multiply the rate by 100, so 0.8*100 = 80%.
The percentage of inter-rater reliability is 80%.
