You can give random values such as <span> (1,2.5) (2,9) (-1,2.5) (-2,9) and it is a parabola. You'll see that the range is (-infinte, 0] and the domain is (-infinit, infinite). </span>I hope that this is the answer that you were looking for and it has helped you.
Answer:
1. 2/4 = 1/2
2. 9/24= 3/8
3. 56/64= 7/8
Step-by-step explanation:
Answer:
0.1587
Step-by-step explanation:
Here, mean=μ=100 and standard deviation=σ=16.
We have to find P(average MDI scores of 64 children > 102)=P(xbar>102).
n=64
μxbar=μ=100
σxbar=σ/√n=16/√64=16/8=2
P(xbar>102)=P((xbar-μxbar)/σxbar>(102-100)/2)
P(xbar>102)=P(z>1)
P(xbar>102)=P(0<z<∞)-P(0<z<1)
P(xbar>102)=0.5-0.3413
P(xbar>102)=0.1587
Thus, the probability that the average is greater than 102 is 15.87%
6 is in the hundredths place (1/100) in 4.768... so 6 has the value of 0.06
