Answer: P(22 ≤ x ≤ 29) = 0.703
Step-by-step explanation:
Since the machine's output is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = output of the machine in ounces per cup.
µ = mean output
σ = standard deviation
From the information given,
µ = 27
σ = 3
The probability of filling a cup between 22 and 29 ounces is expressed as
P(22 ≤ x ≤ 29)
For x = 22,
z = (22 - 27)/3 = - 1.67
Looking at the normal distribution table, the probability corresponding to the z score is 0.047
For x = 29,
z = (29 - 27)/3 = 0.67
Looking at the normal distribution table, the probability corresponding to the z score is 0.75
Therefore,
P(22 ≤ x ≤ 29) = 0.75 - 0.047 = 0.703
It has already given you the answer.

Answer:
<em>x</em> = 3.5
Step-by-step explanation:
P= 55
l= 2x+4
W= 3x+6
P= 2(L+W)
55= 2(2x+4+3x+6)
55=2(5x+10)
55=10x+20
35=10x
3.5=x
Answer:
Step-by-step explanation:

second: (-1/3 )x +1/4
third: (3/4)x +1/3
