Answer:
A is true.......................b is false....................and c is false
Step-by-step explanation:
The probability that the transistor will last between 12 and 24 weeks is 0.424
X= lifetime of the transistor in weeks E(X)= 24 weeks
O,= 12 weeks
The anticipated value, variance, and distribution of the random variable X were all provided to us. Finding the parameters alpha and beta is necessary before we can discover the solutions to the difficulties.
X~gamma(
)
E(X)=
=
=6 weeks
V(x)=
=24/6= 4
Now we can find the solutions:
The excel formula used to create Figure one is as follows:
=gammadist(X,
,
, False)
P(

P(
)
P(
)
P= 0.424
Therefore, probability that the transistor will last between 12 and 24 weeks is 0.424

No I do not want to have fun I’m jus typing this cuz I need points
Wow matrixes gg
a)[ 1 1 4 ]
[-7 -6 -1 ]
[ 0 4 0 ]
b)[ 15 12 12 ]
[-12 -12 0 ]
[3 6 0 ]
c)[ 7 4 12 ]
[ -18 -16 -2 ]
[ 1 10 0 ]
d) I forgot how to do d lol so heres all I got.
A) 0.59 uses 2 sig figs
B) 100.6 uses 4 sig figs (the zeros in this case are significant)
C) 98.42 uses 4 sig figs
D) 1.045 uses 4 sig figs (the zero is between other sig figs so it's significant)
Every choice but choice A has 4 sig figs. So the answers are B, C, and D
