Answer: −1.409
Step-by-step explanation:
Probability of drawing 3 hearts: 13/52 * 12/51 * 11/50 = 0.013
Probability of drawing 3 black cards: 26/52 * 25/51 * 24/50 = 0.118
Probability of other draw: 1 - 0.013 - 0.118 = 0.869
0.013 * (50 - 5) = 0.585
0.118 * (25 - 5) = 2.353
0.869 * (0 - 5) = -4.347
Expected value: 0.585+ 2.353 - 4.347 = -1.409
So first let me assume that the Total profit of the racquets are 8 percentage and not individually.
Now to find the profit we can do
20 x 100= 2000
Now
8=x/2000*100
X= 160
And now for loss
10x80=800
Now
15= x/800*100
X=120
Now profit =
160-120 = 40
The profit was only 40
Answer:
x = 37
Step-by-step explanation:
Power Theorem: 10 x (10 + 26) = 8 x (8 + x)
360 = 8 x (8 + x)
8 + x = 45
x = 37
What is an estimate of 23 times 67
1,500
Answer:
70.99
Step-by-step explanation:
Use Pythagorean Theorem to find the shortest distance.
80^2-50^2=3900
Square rt= 62.44
Subtract by 15
47.44
Next find half of the circular path it is (3.14 x 15)/2
23.55
Add 47.44+23.55=70.99
Hope this is correct
