Answer:
The mean of W is 55 ounces.
The standard deviation of W is 4.33 ounces.
Step-by-step explanation:
Let X: weight of a red delicious apple, and B: the weight of the box and packing material.
The distribution that will represent W: the total weight of the packaged 5 randomly selected apples will be also normally distributed.
Applying the property of the mean: 
, the mean of W will be:
Applying the property of the variance: 
, the variance of W will be:
The mean standard deviation of W will be the squared root of V(W):
The mean of W is 55 ounces.
The standard deviation of W is 4.33 ounces.
I assume you're looking for the value of x?
Combine like terms: 8x+5x+2x-11+6=180 -> 15x-5=180
Add 5 to both sides: 15x=185
Divide both sides by 15: x=12 1/3
So x is 12 1/3 or 37/3
Hope this helped!
<span>The expression for the total price paid for all snacks (P pence)= 4n Pence
will be; P=4n.
Calculation:
let the total price for the four snacks be P pence.
let the four snacks be s1,s2,s3, and s4;
their prices are:
s1=n pence; s2= n pence; s3=n pence; s4= n pence.
therefore;
the total price paid for all snacks (P pence)= s1 price +s2 price +s3 price +s4 price = n+n+n+n= 4n
hence; P=4n
i.e. the total price paid for all snacks (P pence)= 4n Pence</span>
