Answer:
3.25 pounds
Step-by-step explanation:
Starting with 25 pounds we trim off 35%:
25 X .35 = 8.75 trimmed off
This leaves 25 - 8.75 pounds of trimmed meat:
25 - 8.75 = 16.25 of trimmed meat.
During cooking we lose another 80% of the weight of the meat:
16.25 X .80 = 13 pounds "cooked off"
So the remaining weight of meat is 16.25 - 13:
16.25 - 13 = 3.25 pounds of trimmed cooked meat.
How sad is that?

Answer:
0.9127
Step-by-step explanation:
We solve using this z score formula
z = (x-μ)/√n
where x is the raw score
We are told that:
The sample mean would differ from the population mean by less than 231 miles
μ is the population mean = 49360
Hence,
(x-μ) = 231 Miles
σ is the population standard deviation.
We were given variance = 6,568,969
Standard deviation = √variance
= √6,568,969
= 2563
n = random number of tires = 247 tires
z = 231/256/√247
z = 1.41648
Probability value from Z-Table:
P(x < 49591) = 0.92168
≈ 0.9217
The probability that the sample mean would differ from the population mean by less than 231 miles in a sample of 247 tires if the manager is correct is 0.9127
Alright, lets get started.
Suppose previously I was selling product per week = x
As per question, I have decreased my average number of product by 15 %
Means I have decreased number of product by : x * 15 % = x * 0.15 = 0.15 x
So, the new average product = x - 0.15 x = 0.85 x
As per given question, the new average product = 21.25
0.85 x = 21.25
Dividing by 0.85 in both sides
0.85 x / 0.85 = 21.25 / 0.85
x = 25
Hence it means, 25 products were selling previuosly. : Answer
Hope it will work :)
