Below is a probability distribution for the number of failures in an elementary statistics course. X 0 1 2 3 4 P(X=x) 0.41 0.18
faust18 [17]

Answer:

a) P(X=2)= 0.29

b) P(X<2)= 0.59

c) P(X≤2)= 0.88

d) P(X>2)= 0.12

e) P(X=1 or X=4)= 0.24

f) P(1≤X≤4)= 0.59

Step-by-step explanation:

a) P(X=2)= 1 - P(X=0) - P(X=1) - P(X=3) - P(X=4)= 1-0.41-0.18-0.06-0.06= 0.29

b) P(X<2)= P(X=0) + P(X=1)= 0.41 + 0.18 = 0.59

c) P(X≤2)= P(X=0) + P(X=1) + P(X=2)=0.41+0.18+0.29= 0.88

d) P(X>2)=P(X=3) + P(X=4)=0.06+0.06= 0.12

e) P(X=1 or X=4)=P(X=1 ∪ X=4) = P(X=1) + P(X=4)=0.18+0.06= 0.24

f) P(1≤X≤4)=P(X=1) + P(X=2) + P(X=3) + P(X=4)=0.18+0.29+0.06+0.06= 0.59

Which of the following rational numbers is equal to 2 point 8 with bar over 8 ? twenty two over nine, twenty four over nine, twe
alina1380 [7]
Just to remove ambiguities, the bar over the expression means it's repeating itself to infinity.

\bf 2.888\overline{8}\impliedby \textit{now say, let's make }x=2.888\overline{8}&#10;\\\\\\&#10;\textit{and multiply it by 10, to move over the 8 to the left}&#10;\\\\\\&#10;\begin{array}{llll}&#10;10x&=&10\cdot 2.888\overline{8}\\&#10;&&28.88\overline{8}\\&#10;&&26+2.888\overline{8}\\&#10;&&26+x&#10;\end{array}\implies 10x=26+x&#10;\\\\\\&#10;9x=26\implies x=\cfrac{26}{9}

notice, the idea being, you multiply it by 10 at some power, so that you move the "recurring decimal" to the other side of the point, and then split it with a digit and "x".

now, you can plug that in your calculator, to check what you get.
