Mass over volume g/mL: so it would be 5mL as tge volume and 2 g/mL as the density.
Answer:
0.2187
Step-by-step explanation:
Americans consume on average 92 pounds of chicken per year, with a standard deviation of 10.3 pounds. What is the probability that a sample of 50 people will have consumed an average of 100 pounds or more?
We to find
x ≥ 100 pounds
To solve for the above question, we use the z-score formula
z = (x-μ)/σ, where
x is the raw score = 100 pounds
μ is the population mean = 92 pounds
σ is the population standard deviation = 10.3
Hence:
z = (100 - 92)/ 10.3
z = 8/1.46
z = 0.7767
Probability value from Z-Table:
P(x<100) = 0.78133
P(x>100) = 1 - P(x<100) = 0.21867
Approximately = 0.2187
Therefore, the probability that a sample of 50 people will have consumed an average of 100 pounds or more is 0.2187
If it makes it any easier, when you see "a thousand liters," think of 260 gallons of milk. Which do you think could it fill up without going over?
In order to calculate the surface area of the given figure, use the following formula:
S = 2wl + 2wh + 2lh
where:
w: width = 7 in
h: height = 3 in
l: length = 4 in
replace the previous values of the parameters into the formula for S:
S = 2(7 in)(4 in) + 2(7 in)(3 in) + 2(4 in)(3 in)
S = 56 in² + 42 in² + 24 in²
S = 122 in²
Hence, the surface area of the given figure is 122 in²
