Answer:the anser is a
Step-by-step explanation:
To check all the events (6), we label the chips. Suppose one chip with 1 is labeled R1 and the other B1 (as if they were red and blue). Now, lets take all combinations; for the first chip, we have 4 choices and for the 2nd chip we have 3 remaining choices. Thus there are 12 combinations. Since we dont care about the order, there are only 6 combinations since for example R1, 3 is the same as 3, R1 for us.
The combinations are: (R1, B1), (R1, 3), (R1, 5), (B1, 3), (B1, 5), (3,5)
We have that in 1 out of the 6 events, Miguel wins 2$ and in five out of the 6 events, he loses one. The expected value of this bet is: 1/6*2+5/6*(-1)=-3/6=-0.5$. In general, the expected value of the bet is the sum of taking the probabilities of the outcome multiplied by the outcome; here, there is a 1/6 probability of getting the same 2 chips and so on. On average, Miguel loses half a dollar every time he plays.
The slope of a line is the rate of change of the line
The slope of the line is -3/2
The points on the line are given as:
The slope (m) is calculated as:
So, we have:
Rewrite as:
Hence, the slope of the line is -3/2

Answer:
-3 over 2
Step-by-step explanation:
I took the test and got it right and just wannted to verify. Also because since 1,1 is that it would be proportional if it wwas 3,3 but it is -3,2.
PLEASE MAKE BRANLIEIEST AND 5.0
In ∆ ABC, a =32, b = 44, and m < A = 68*
How many distinct triangles can be drawn given these measurements?
Answer:
None (zero)
Step-by-step explanation:
32/sin(68) = 44/sinB
sinB = 1.2748778
Not possible
Solve for a
3b=10b-49
Solve for b
Answer:
The first answer is a = 10, The second answer is b = 7
Step-by-step explanation:
Equation 1: 5a = a + 40
To solve for a, you want to isolate a on one side of the equation. You can do this by subtracting "a" from both sides of the equation:
5a - a = a - a + 40
This simplifies to:
4a = 40
Now, divide both sides by 4 to solve for a:
4a/4 = 40/4
a = 10
So, a = 10.
Equation 2: 3b = 10b - 49
To solve for b, you want to isolate b on one side of the equation. First, let's get the "b" terms on one side by subtracting 10b from both sides:
3b - 10b = 10b - 10b - 49
This simplifies to:
-7b = -49
Now, divide both sides by -7 to solve for b:
(-7b) / (-7) = (-49) / (-7)
b = 7
So, b = 7.

Answer: A. cm
Step-by-step explanation: The formula for the volume of a hexagonal prism is, volume = [(3√3)/2]a2h cubic units where a is the base length and h is the height of the prism. We can also use the other formula V = 3abh, where a = apothem length, b = length of a side of the base, and h = height of the prism.
121 gallons of gas
25 gallons of gas
115 gallons of gas
Answer:
Step-by-step explanation:
To calculate how many gallons the van needs to travel 550 miles you should multiply the number of miles by the relationship between the number of gallons of gas it needs to travel 220 miles, (it is important to put the quantity in miles on the denominator) as follows:
Therefore the van needs 25 gallons of gas to travel 550 miles
