Answer: I think its C I hope this helps!!!!!!
Step-by-step explanation:
So,we have to work with the equation 3w-8= 7
We move eight to the other side as a positive number
3w= 8+7
3w=15
Divide both sides by three to get the value of w
15/3 = 5
Therefore, w is equal to five
Now that we have the value of w, we substitute it into 7w+7
7(5)+7
35+7= 42
Therefore the value of 7w+7 is 42
The mean is 8
Mean means average so do 6+10+6+10= 32
Then divided by 4 bc that’s the amount of numbers u added together
32/4 =8
Standardised z score = (16.075 - 16) / 0.2 = 0.375
which gives a probability of 0.1462 for selecting a package of weight 16.075
the probability of weight being excess of 16.075 = 0.5 - 0.1462 = 03538
Probability of picking 16 in excess of 16-075 = 0.3538^16 = 6.0273 * 10^-8
