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:
4m is the answer.
Step-by-step explanation:
a = 3m
b = ?
c = 5m
According to the Pythagoras theorem,
a² + b² = c²
3² + b² = 5²
9 + b² = 25
b² = 25 - 9
b² = 16
b = 4m
∴ The distance between the ladder and the bottom of the slide is 4m.
Domain is all x-values
Range is all y-values
When comparing fractions it is important to note the numerator and denominator. If the denominators are the same, the largest numerator is the larger number (because it represents more pieces of the same size). If the numerators are the same, then the smaller denominator is the larger number (because the pieces are bigger).
So in your problem,
5/8 is more than 3/8 So more muffins had blueberries.
Answer:
y = 2/5x + 39/5
Step-by-step explanation:
point slope form is y = mx + b
so far we have y = 2/5x + b
m is slope which is given. We need to find b which is y-intercept.
They give us the point (-2,7). We can plug this into the equation to find b.
7 = 2/5(-2) + b
7 = -4/5 + b
b = 39/5
The equation now looks like y = 2/5x + 39/5
