Probabilities of Q are 1,4, 16, 64 are 312 2 8181818 , E(Q)=20.88 and 12.5% information revealed. Wheel is spin twice 0.2815.
When we are not sure about the outcome we can make possible probabilities about the situation. Therefore, it is the maximum and possible chances of something to be happen.
Step 1
Angle of one complete spin = 360°
Q=16=90° Q=6490"
Q=4-450
Q=1=135°
Here
P(Q16) = P(Q= 64)
=90/36
=1/4
Step 2
Expected value E(Q) = xP(x) E(Q) = 1x+4x+16x+64 x2/8
Step 3
c)
We learn Q=4
P(Q=4)=1/8=0.125
12.5 % information is revealed.

<span>1) The number of subscribers to magazine A in 2000 is 5,000 more than the number of subscribers to magazine B in 2000.
2) Which of the following describes the number of subscribers represented by the tables?
The number of subscribers to both magazines are decreasing.
3) As the number of years since 2000 increases, the number of subscribers both magazines approach zero.</span>
The simplified version of this expression is -4x.
Work
1. 1x-7x-(-2x)
2. 1x-7x+2x
Now just combine the terms.
3. -6x+2x
4. -4x
Answer:
1. 24+40+48+24=136 2. 384
Step-by-step explanation:
for 1- first you find the area of the triangles or whatever you like i did that, together it was 24. then you find the rest of the sides area which are 40, 48, and 24 considering the dimensions. The Volume is 136 cm cubed.
2. 384- you multiply all the numbers together and get 384, pretty self explanatory.
