vodomira [7]
3x + 1 = y

x: 1 | 2 | 3  |
------|---|--- |----------------
y: 4 | 7 | 10|

so make points at (1,4) (2,7) and (3,10), and connect them to get the line

4x + 1

x: 1 | 2 | 3
----------------
y: 5 | 9 | 13

Make points at (1,5) (2,9) and (3,13)

IF they do not intersect yet, continue making points until they intersect. Make note of the point in which they intersect, and that is your answer

hope this helps

The question is: Write and solve an equation to determine the width 'w' of the flag. The length of an American flag is 1.9 times
AysviL [449]

So what is given is:

length = 1.9 * w, you want to convert this to w = ...

This is done by dividing left and right by 1.9, so you get:

length/1.9 = 1.9*w/1.9, which simplifies to w = length/1.9

Another approach is to replace the multiplication with a simpler one in your head. So in stead of reading "length = 1.9 * width, what is width?", you read "6 = 2*3, what is 3?". You'll immediately realize 3 = 6/2, and that shows you how to change the real equation, ie., width = length/1.9.

Open Tornadoes-HW6 data. Test if there is a significant difference between the number of tornadoes in August and the number of t
jenyasd209 [6]

Answer:

<u>Use Two sided t-test</u>

<u>Step-by-step explanation:</u>

Note that, there are other tools to test for significant difference such as simple regression or multiple regression<em> but when comparing the results of two groups in terms of which is higher or lower</em>, then a two sided t-test would be best appropriate.

Since we want to know if there is a significant difference between the number of tornadoes in August and the number of tornadoes in October on average we use the two sided t-test because a Two sided t-test can show the possibility of positive or negative differences.
