Answer:
im not exactly sure, but i think it would be PART A: either option B or D by going diagonal across the grid and then normal across the grid. PART B: option B because that is the shortest option going diagonal that matches with the options available

Answer:
13+x
Step-by-step explanation:
all you have to do is 9+4 which is 13 and leave the +x so you get 13+x as your answer
Answer:
5
Step-by-step explanation:
Hello There!
The mean is pretty much the average
So to find the mean we first add up all of the values
2+3+6+6+7+8+8=40
Then we count the amount of points
There are 8 points
our final step is to divide the total value by the total number of points
40/8=5
so the mean (average) would be 5
Answer:
a
The estimate is 
b
Method B this is because the faulty breaks are less
Step-by-step explanation:
The number of microchips broken in method A is 
The number of faulty breaks of method A is 
The number of microchips broken in method B is 
The number of faulty breaks of method A is 
The proportion of the faulty breaks to the total breaks in method A is


The proportion of the faulty to the total breaks in method B is

For this estimation the standard error is

substituting values


The z-values of confidence coefficient of 0.95 from the z-table is

The difference between proportions of improperly broken microchips for the two breaking methods is mathematically represented as
![K = [p_1 - p_2 ] \pm z_{0.95} * SE](https://tex.z-dn.net/?f=K%20%3D%20%5Bp_1%20-%20p_2%20%5D%20%5Cpm%20z_%7B0.95%7D%20%2A%20SE)
substituting values
![K = [0.08 - 0.07 ] \pm 1.96 *0.0186](https://tex.z-dn.net/?f=K%20%3D%20%5B0.08%20-%200.07%20%5D%20%5Cpm%201.96%20%2A0.0186)

The interval of the difference between proportions of improperly broken microchips for the two breaking methods is
