Answer: Hence, Option (6) and (8) are correct as their value is also "-8".
Step-by-step explanation:
Since we have given that
First we need to solve to get the value of 'x' :
Therefore, x=-8
Now, we will check all the options :
1) 4x+8=24
2) 9x+18=-24
3) 4x+12=-24
4) 18x+36/2=-24
5) 4x=-36
6) 4x=-32
7) x=-9
8) x=-8
Hence, Option (6) and (8) are correct as their value is also "-8".
Solution: We are given:
Let be the weight (oz) of laptop
We have to find
To find the this probability, we need to find the z score value.
The z score is given below:
Now, we have to find
Using the standard normal table, we have:

Step-by-step explanation:
Answer:
If you are <u>traversing squares</u> then 7 different paths can be taken
If you are <u>traversing edges </u> then 36 different paths can be taken
Step-by-step explanation:
I have attached a picture that would describe the grid which is 7 units long.
The solution to the general problem is if you have to take X right steps, and Y down steps then the number of routes is simply the ways of choosing where to take the down (or right) steps. Such that:
Basically its the combination of terms.
In this problem,
If you are <u>traversing squares</u> then there are 6 right steps and 1 down step,
7 C 1 = 7 C 6= 7
If you are <u>traversing edges </u> then there are 7 right steps and 2 down steps:
9 C 2 = 9 C 7= 36
