The expected value after 10 game at a carnival is 16.1 tickets.
Given the probabilities that bag lands into the outer ring, middle ring, center are 0.64, 0.11 and remaining. 1 ticket awarded for the outer, 2 for middle and 3 for middle.
We have to find the expected value we will get if we play the game 10 times.
Probability is the chance of happening an event among all the events possible. Value of probability lies between 0 and 1. The formula of probability is as under:
Probability=number of items/ total items in consideration.
Probability that bag lands in center is 1-0.64-0.11=0.25.
Expected value when game is played 1 time=1*0.64+2*0.11+3*0.25
=0.64+0.22+0.75
=1.61
Expected value when the game is played 10 times=10*1.61
=16.1 tickets.
Hence the expected value when game is played 10 times is 16.1 tickets.

Subtract 6x^{2}-7x-2 from 6x^{2}-2x+6
Hello!
Let's subtract!
⇒ 6x² - 2x + 6 - (6x² - 7x - 2)
⇒ 6x² - 2x + 6 - 6x² + 7x + 2
⇒ 5x + 8
∴ The difference will be equal to 5x + 8.
Answer:
Your answer is 5x+8
Step-by-step explanation:
= 6x^2-2x+6 - (6x^2-7x-2)
= 6x^2-2x+6 - 6x^2+7x+2
= 6x^2- 6x^2-2x+7x+6+2

For choice A, order matters. This is because of the positions of first place and second place are different from one another. Since order matters, we have a permutation for choice A and can rule it out.
Choices C and D are ruled out for the same reason.
Choice B is a combination. It doesn't matter what the order of the CDs are. All that matters is the group overall rather than the individual CDs.

Lower bound = 41.3
Upper bound = 41.5
===========================================================
Explanation:
49.15 is the smallest f can be while 49.24 is the largest it can be. Well technically we could have something like 49.2499 or 49.24999 and so on. We slowly approach 49.25 but never actually get there
So the variable f is between 49.15 and 49.25 inclusive of the first value but excluding the second value. We can write it as [tex]49.15 \le f < 49.25[/tex]
For similar reasoning, [tex]7.75 \le g < 7.85[/tex]
-----------------
If we wanted to subtract those variables and get the smallest result possible, then we need to pick values that are closest together. It might help to set up a number line.
This means we'd go for f = 49.15 and g = 7.85
The lower bound for f-g is f-g = 49.15-7.85 = 41.3
In contrast, the upper bound is when the two variables are spaced as far apart as possible. The upper bound is f-g = 49.25 - 7.75 = 41.5
Answer:
See below
Step-by-step explanation:
49.2 could be 49.15 <= f < 49.25
7.8 could be 7.75 <= f < 7.85
Lower bound of f- g would then be 49.15 - 7.85 > 41.3
upper bound 49.25 - 7.75 < 41.5
41.3 < f-g < 41.5

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The line l and the line m are parallel to each other.
The angle ∠7 = 4x – 3 and angle ∠14 = 5x – 8.
Then the measure of angle ∠16 will be
The angle ∠14 and angle ∠16 are the supplementary angles. Then we have
∠14 + ∠16 = 180°
5x – 8 + ∠16 = 180°

One car travels 30 meters east in 5 seconds. A second car travels 42 meters west in 7 seconds. During their respective periods of travel, the cars must have had the same _______________.
The cars must have had the same Average Speed
Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speed, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.
The average speed of a body is equal to the total distance covered, divided by the total time taken. The formula for average speed is given as:
[tex]\frac{Total distance covered by the object}{Total time taken}[/tex]
Given :-
Distance covered by A = 30 metersTime taken by A = 5 secondsDistance covered by B = 42 metersTime taken by B = 6 secondsSubstituting the given values in the formula for A and B respectively we get
Average Speed of A = [tex]\frac{30}{5}[/tex] m/s = 6 m/s
Average Speed of B = [tex]\frac{42}{7}[/tex] m/s = 6m/s
Thus the cars must have had the same Average Speed.

2x+11 = x +44
First we need to find x

2x+11-x = x+44
x +11 = 44
Subtract 11 from each side
x+11-11 = 44-11
x =33
Now we can find the exterior angle
2x+11 = 2(33)+11 = 66+11 = 77

The completed construction of regular hexagon is shown below explain why act is a 30-60-90 triangle
In a 30°-60°-90° triangle, the length of the longer leg is √3 times the length of the shorter leg and length of the hypotenuse is twice the length of the shorter leg.
How to explain the reasonACF is a 30º-60º-90º triangle because of the following reasons;
Based on a theorem, in a 30°-60°-90° triangle, it is said that the length of the longer leg is √3 times the length of the shorter leg and length of the hypotenuse is twice the length of the shorter leg,
1 → short leg = 1
2 → hypotenuse = 2
√3 → long leg = √3
Using the Pythagorean theorem., we have that
a² + b² = c²
1² + b² = 2²
b² = 2² - 1²
b² = 4 - 1
b² = 3
√b² = √3
b = √3
