Answer:
19
Step-by-step explanation:
The equation has "absolute value" , "addition", "subtraction", "division", and "multiplication", and "parenthesis".
The order we follow here would be:
PEMDAS, which is "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction"
Also, note, we can do absolute value first, before these.
Now let's simplify using PEMDAS:
So the answer is 19 (note: i used "/" sign for "division")

Answer:
a) 14960 bottles
b) 502 bottles
Step-by-step explanation:
Given that:
Mean (μ) = 24 ounces, standard deviation (σ) = 0.14 ounces
a) From empirical rule (68−95−99.7%) , 68% of the population fall within 1 standard deviation of the mean (μ ± 1σ).
Therefore 68% fall within 0.14 ounces of the mean
the number of bottle = 22,000*68% = 14960 bottles
b) To solve this we are going to use the z score equation given as:
where x is the raw score = 23.72
From the normal probability distribution table: P(X < 23.72) = P (Z < -2) = 0.0228
The number of rejected bottles = 22000 × 0.0228 = 502 bottles
