Answer:
2.5
Step-by-step explanation:
We can see that the original length of RS is 2 units. The length of R'S' is 5 units.
2 * x = 5
2x = 5
x = 5/2
x = 2.5
(1,2)
The solution is where the lines intersect so you can see they intersect at (1,2)
Answer:
x = 63.9
Step-by-step explanation:
We have:
= 
=> QR × sin90 = 78 × sin35
=> QR × sin90 = 44.7
=> QR = 44.7
But, we also have: 
+ 
= 
<=> + 
= <=> = 6084 - 1998.09
=> = 4085.91
=> x = 
= 63.9211.. = 63.9
<3 Have a nice day!!
Answer:
-$2.63
Step-by-step explanation:
Calculation for the expected profit for one spin of the roulette wheel with this bet
Based on the information given you bet $50 on 00 while the standard roulette has 38 possible outcomes which means that the probability or likelihood of getting 00 will be 1/38.
Therefore when we get an 00, we would get the amount of $1,750 with a probability of 1/38 and in a situation where were we get something other than 00 this means we would lose $50 with a probability of 37/38.
Now let find the Expected profit using this formula
Expected profit = sum(probability*value) -sum(probability*value)
Let plug in the formula
Expected profit =($1,750 * 1/38) - ($50 * 37/38)
Expected profit=($1,750*0.026315)-($50×0.973684)
Expected profit= 46.05 - 48.68
Expected profit = - $2.63
Therefore the expected profit for one spin of the roulette wheel with this bet will be -$2.63
