<span>P(liberal | State A) means that probability of liberal candidates to be voted for within state A. This probability could be calculated by the pattern: number of successful events/total events. The successful events referred here is the number of liberal votes in state A. That is equal to 22. The total events is the total number of votes in state A which is 40. 

Thus, the probability is 22/40 = 0.55</span>

Orange box:

The incorrect statement is B. The theoretical probability is the probability of an event occurring that is expected. In this case, the theoretical probability of selecting a dime is 4/25.

Purple box:

The incorrect statement is C. The difference between the theoretical and experimental probability is not 1/10. The difference between the experimental and theoretical probability is 0.015 or 3/200.

6/25 = 0.24

9/40 = 0.225

0.24 - 0.225 = 0.015

Hope this helps!! :)

A rectangular box with a square base is open at the top and has a volume of 12 cubic feet. Each side of the base has a length of
Stolb23 [73]

We know that the side lengths of the square base are: x * x. The volume is 12, so for now, let's say that y is the other side length. Then, x * x * y = 12. We can solve for y: y = 12/x^2. Now, we find the surface area of the 5 sides.

Four of the sides have the same area: x * (12/x^2) = 12/x, so we multiply this by 4: 48/x.

The last side is the base: x * x = x^2.

We add 48/x to x^2:

x^2 + 48/x

So, the answer is the fourth choice, (d).

Which statement is correct? A) 13/ 3 &lt; 4.25 &lt; 43 /10 B) 43 /10 &lt; 13 /3 &lt; 4.25 C) 4.25 &lt; 13 /3 &lt; 43/ 10 D) 4.25
Ivan
D. 4.25 < 43/10 < 13/3 
     
4.25   = 4.25
43/10 = 4.3
13/3   = 4.33

4.25 < 4.3 < 4.33

For Bill's birthday his mom is bringing donuts to school.
kipiarov [429]

36 donuts (2 1/2 dozen) = $8.00

So, you divide 8 by 36 and you get about 22¢ for each donut. Then, you do .22 x 12 which equals $2.64.

One dozen donuts = $2.64
