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%
Divide 3/4 by 1/8 and you should get 6 hurdles.

easy find the LCM ,divide by the denominator and multiply by the numerator in every number and then you add them altogether
Answer:
False
Step-by-step explanation:
Usually there are three different lights on a stop light to consider
With three lights, the chance that the light is yellow would be about 33.334%
If it were to be a 50/50 chance then there would only be two lights
