Answer:
The probability of Dan making less than $255 is 0.5987 or 59.87%
Step-by-step explanation:
Given that:
Mean = μ = $240
SD = σ = $60
We have to find the probability that Dan will make less than $255
First of all, we have to find the z-score of 255
z-score is denoted by z and is given by the formula
Here,
x = 255
Putting the values
Now we have to look at the z-score table to find the probability of 0.25
P(x<255) = 0.5987
Converting into percentage
59.87%
Hence,
The probability of Dan making less than $255 is 0.5987 or 59.87%
Answer:
Reactive power is 1.152 VARs
Step-by-step explanation:
We are given that in a parallel circuit,,R=47kΩ and
=50kΩ.
reactive power means the dissipating power resulting from inductive and capacitive loads measured in volt-amperes reactive(VAR).Since our circuit has inductor only, reactive power will be power dissipated from inductor.
Current through inductor=milli amps=0.0048 A
Reactive power = (current flowing through inductor)X (Voltage across inductor)
Hence reactive power = 0.0048 X 240=1.152 VARs
Answer: 0.0014
Step-by-step explanation:
Given : Number of entries in horse race = 13
Number of horses owned = 4
We assume that there are no ties .
Then , the probability that those four horses finish first, second ,third ,and fourth is given by :-
Hence, the required probability = 0.0014
