Answer:
Concept: Unit Price & Algebraic Representation
- You have 12 oz
- You have a total price of 2.10
- Hence you divide 2.10/12
- Your result to the nearest tenth is 0.2
- Rate positively and give brainlist
= (y+6) +y =10
= 2y + 6 = 10
= 2y = 4
Y= 2

Answer:
The probability is 0.017429
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)/SD/√n
In this case;
x = 273
mean = 276
SD = √(variance) = √81 = 9
n = 40
Substituting these values into the z-score formula, we have that;
z = (273-276)/9/√40
z = -2.11
So we proceed to get the probability
the probability in this case is;
P( z < -2.11)
We can use the normal distribution table for this
Our answer will be
P( z < -2.11) = 0.017429
