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:
0.9236 or 92.36% of laptops are overweight
B^2=9^2
9^2=81.
81 = answer
Answer:
k = 5
Step-by-step explanation:
-2k = k - 7 - 8
Combine like terms
-2k = k - 15
add 15 to both sides
-2k + 15 = k
Add 2k to both sides
15 = 3k
Divide both sides by 3
k=5
Hope this helps!
