Answer:
y = - 10
Step-by-step explanation:
Given
y - 3 = - 3y - 43 ( add 3y to both sides )
4y - 3 = - 43 ( add 3 to both sides )
4y = - 40 ( divide both sides by 4 )
y = - 10
The correct answer is A) y - 4 = -2/5(x + 1)
We know this because of the basic form of point slope form, which is shown below.
y - y1 = m(x - x1)
In which the point (x1, y1) is on the graph and m is the slope. When counting the slope, we can see that it is -2/5 based on the fact that for every two spaces the graph travels down, it moves to the right five. This eliminates options C and D and gives us this form to work with.
y - y1 = -2/5(x - x1)
Now we have the point (-1, 4), so we can plug this in to match it with a formula.
y - 4 = -2/5(x - -1)
y - 4 = -2/5(x + 1)
Answer:
Type I error occurs when the null hypothesis, H0, is rejected, although it is true.
Here the null hypothesis, H0 is:
H0: Setting weekly scheduled online interactions will boost the well being of people who are living on their own during the stay at home order.
a) A Type I error would be committed if the researchers conclude that setting weekly scheduled online interactions will not boost the well being of people who are living on their own during the stay at home order, but in reality it will
b) Two factors affecting type I error:
1) When the sample size, n, is too large it increases the chances of a type I error. Thus, a sample size should be small to decrease type I error.
2)A smaller level of significance should be used to decrease type I error. When a larger level of significance is used it increases type I error.

Look at the angles and the little tallies to match up the triangle. Or use the given: triangle DEF is similar to triangle KJI. If it’s like that in a given you know the order is equal. (D and K are similar, E and J, and F and I)
So if line FD is the 3rd and 1st letters of the first triangle, then it has to be equal to the 3rd and 1st letter of the 2nd triangle.
IK
Another way to do this is that when you find FD on the triangle you can set that the line has 3 tally marks. Then look at the other triangle and find a line in which there are 3 tally marks.
The order in which you put the letters does not matter. IK and KI should both be considered correct
Hope this helped
