You take the top box and combine it with the bottom right hand box and remove the right stick on the bottom box to continue combination.
Answer:
The x coordinate would be 4.
Step-by-step explanation:
In order to find this, we'll make the y terms cancel. To do this, we need to multiply the whole second term by -1 and then add them together.
3x + 5y = 10
-x - 5y = -2
-----------------
2x = 8
Now that we have this, we can divide to get the answer.
2x = 8
x = 4
Answer:
9.06
Step-by-step explanation:
1. Add up all data values to get the sum:
-8 + 12 + 25.9 + -6.3 + 21.9 = 45.5
2. Count the number of values in your data set:
5
3. Divide the sum by the count:
45.4/5 = 9.06
4. You can round to 9.1
Answer:
Step-by-step explanation:
Given
----- variance
------------ sample
Required
Determine the S.E
The estimated standard error (S.E) for the sample mean is calculated using the following formula:
Where
So:
Hence: the estimated standard error for the sample mean is 2
39/69 = 13/23 is in simplest form
First you do 39 divide by 3 = 13 and do 69 divid by 3 = 23
