A card game goes like this: you draw a card from a 52-card deck. if it is a face card (jack, queen or king), you win $4; otherwi
GREYUIT [131]
Your expected value is -$0.62.

We multiply the probability of winning by the amount won.  There are 12 face cards out of 52 cards, and the amount won is 4:

12/52(4)

We also multiply the probability of losing by the amount lost.  There are 40 cards that are not face cards out of 52, and the amount lost is 2:

40(52)(-2)

Adding these, we have: 

(12/52)(4)-(40/52)(2) = -0.62.

HI HELP ASAP PLEASE EXPLAIN HOW TO DO STUFF LIKE THIS PLEASE HELP
statuscvo [17]

Given:

∠A = 66°

AB = 5 mi

To find:

The distance from point B to point C.

Solution:

Using trigonometric ratio formula:

$\tan \theta=\frac{\text { Opposite side of } \theta}{\text { Adjacent side of } \theta}

$\tan A =\frac{\text { Opposite side of } A }{\text { Adjacent side of } A}

$\tan 66^\circ =\frac{BC}{AB}

$2.25 =\frac{BC}{5}

Multiply by 5 on both sides.

$5\times 2.25 =5\times \frac{BC}{5}

$11.2 = BC (nearest tenth)

The distance from point B to point C is 11.2 mi.

Your teacher gave you 2/3 a bag of candy, but she only gave your friend 1/8 of a bag.
Mrrafil [7]

Answer:

Step-by-step explanation:

We can convert the 2/3 bag of candy that we got to 16/24, by multiplying both the top and bottom by 8. Similarly, we multipy the 1/8 bag of candy that our friend got by 3 on the top and bottom to get 3/24.

We find the difference between these two:

(16/24) - (3/24) = (16-3)/24 = 13/24

So we get 13/24 more of the bag of candy than our friend did. (That's more than half!)
