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
Answer:
45/100 or 9/20.
Step-by-step explanation:
Divide 45 by100. This can simplify to 9/20
Answer:i think its 15 because if you take the km numbers and subtract them
Step-by-step explanation:
Answer:
coefficients: 1, -5
constant: 6
Step-by-step explanation:
The coefficients are the numbers in front of the variables* in each variable term. Here, they are 1 and -5. The coefficient of x² is 1; the coefficient of x in the term -5x is -5.
As you can see, a coefficient of 1 is rarely written.
__
The constant is the value of the term with no variables. Here, the constant is +6.
_____
* Please note that a coefficient can appear anywhere in the product that is a term: -5x = (x)(-5). This means the term x2 that you have written could also be interpreted as meaning 2x. If you mean the 2 in x2 to be an exponent (as we have assumed), then it should be written x^2 or as a superscript: x².
