The probability is illustrated below.
How to illustrate the probability?1) Raffles game is a gambling competition in which people get numbered tickets and each number has an equal chance of winning.
2) When two dice are rolled then there will be totally 36 outcomes. Of those the outcomes with sum 8 are (2,6),(3,5),(4,4),(5,3),(6,2).
These are 5 in number.
So,P( sum =8)= 5/36.
3)This is a true statement.
4) Here win, lose, or tie is just the outcomes where their probabilities are different from each other and those values depend upon different situations.
5) Tossing a coin is a random experiment which means that the result of the experiment (ie head or tail) cannot be predicted.
6) If 60% said yes to " study during the week" then 40% will say yes to "either won't study or study at weekend".
7) When two coins are tossed, the outcomes are as follows
H,H
H,T
T,H
T,T.
So, P( head, tail ) =2/4 =1/2

The reasons for each incorrect statement are as follows;
The error in the statement is that, there might be other luckier numbers compared to number 7 and hence, the statement does not hold true for all numbers.The statement is incorrect because, there are 36 different possibilities and there are 5 possibilities of getting an 8.The statement is incorrect because, 93% does not necessarily represent a 93% chance of complete recovery as this is subject to other variables.The probability that they win is not 1/3 as it is subject to what the results have been over the years and not just the possible results.Since, the coin is unbiased, it follows that upon flipping the coin for the fifth time, it is not likely to have tails the next time it is flipped.The statement is incorrect because some students study during the week and weekends, hence, the conclusion is not correct.What is Probability?The term probability put simply is the ratio of the desired outcome to the possible outcomes. It therefore follows that probability as the name implies is used to predict the chance of an occurrence.

In the parallelogram below, solve for Y
Options
4
10
25
100
Answer:
x = 4
y = 4
Step-by-step explanation:
the front triangle has two 40° angles (sum of all ∡'s must be 180°)
the unlabeled lower-left angle then is 40°; this angle corresponds to the angle in the other triangle labeled as 10y°
therefore, 10y = 40 so y = 4
Since opposite angles in a parallelogram are congruent then we can write:
40° + 25x° = 100° + 10(4)°
25x° = 140 - 40°
25x = 100°
x = 4

To write in ascending order, means that the number must increase from left to right.
So, we have:
1. -5, 2, 1, -8
From left to right, we have:
[tex]-8 < -5 < 1 < 2[/tex]
Hence, the sorted list: -8 , -5 , 1 , 2
2. -4, -3, -5, 2
From left to right, we have:
[tex]-5 < -4 < -3 < 2[/tex]
Hence, the sorted list: -5, -4 , -3 , 2
3. -10, -15,-7
From left to right, we have:
[tex]-15 < -10 < -7[/tex]
Hence, the sorted list: -15, -10, -7

Determine if the angles are vertical, complementary, or supplementary, and then solve for x. *
x=5
x=16
x=14
x=45
Answer:
x = 14
Step-by-step explanation:
___________________________________________________________
FACTS TO KNOW :-
Linear Pair is a pair of adjacent angles on a straight line whose sum is 180°All linear pairs are supplementary angles (because their sum is 180°) but all supplementary angles are not linear pairs.___________________________________________________________
In the question , the given angles are supplementary angles because both (3x)° & (7x + 40)° are adjacent to each other and they are on a straight line.
As they are supplementary angles , their sum will be 180°.
So ,
[tex](3x) + (7x + 40) = 180[/tex]
[tex]=> 3x + 7x + 40 = 180[/tex]
[tex]=> 10x + 40 = 180[/tex]
Substracting 40 from both the sides ,
[tex]=> 10x + 40 - 40 = 180 - 40[/tex]
[tex]=> 10x = 140[/tex]
Dividing both the sides by 10 ,
[tex]=> \frac{10x}{10} = \frac{140}{10}[/tex]
[tex]=> x = 14[/tex]
A hot dog bun (volume 240cm3) with a density of 0.15g/cm3 is crushed in a picnic cooler into a volume of 195cm3. What is the density of the bun?
Answer:
weight of hot dog bun = 240 cm^3 x 0.15 g/cm^3 = 36 gram
36 gm / 195 cm^3 = 0.185 g/cm^3
Step-by-step explanation:
Density is mass/volume. The mass of the bun never changes, only its volume. Solve for the original mass.
Now think about it logically. Should the bun be more sense now that it has been crushed? Of course! The math proves it.
Therefore the answer is: 0.185 g/cm^3

Find the Area Please
Answer:
The area of this shape is super close/equal to 18.283 [tex]m^{2}[/tex]
Step-by-step explanation:
The area of this shape will be equal to the sum of the area of the trapezoid with the height being 4m and parallel lines being 2m and 4m long, and the area of the semi-circle with the radius of 2m. And so we get...
Let "A" be the total area of this shape, then...
[tex]A = \frac{(a + b)h}{2} +[/tex] π[tex]r^{2}[/tex]/2
[tex]A = \frac{(2 + 6)4}{2} +[/tex] π [tex]2^{2}[/tex]/2
[tex]A[/tex] ≈ 12 + 6.283
A ≈ 18.283 [tex]m^{2}[/tex]

After lunch, you see the bumper cars and want to ride them. Here’s what the sign says:
Bumper Cars:
6 minutes: 8 tickets
8 minutes:12 tickets
Which one gives you more time for your money?
Answer:
The option of 6 minutes with 8 tickets given more time for the money.
Step-by-step explanation:
Which one gives you more time for your money?
We have to find the time per ticket, which is the number of minutes divided by the number of tickets.
6 minutes: 8 tickets
6/8 = 0.(60/8) = 0.75 minutes per ticket.
8 minutes:12 tickets
8/12 = 2/3 = 0.(20/3) = 0.667 minutes per ticket.
So the option of 6 minutes with 8 tickets given more time for the money.

12. A staffs shadow is 8 feet and a tree's shadow is 16 feet. If the staff is 9 feet tall, how tall is the tree?
A. 15 ft
B. 18 ft
C. 12 ft
D. 9 ft
Answer:
18 ft
Step-by-step explanation
1. Put 8/16 like a fraction and since we do not know the height of the tree yet we put the height as 9/d.
2. We have to cross multiply so we multiply 8 by d and we get 8d. Then we multiply 9 by 16 and we get 144.
3. We divide both sides by 8 so we can get (d) by itself and we divide 144 by 8 also.
4. We get d = 18

Answer:
1. 38.7
2. 3.87
3. .387
Step-by-step explanation:
1. So when dividing by numbers with exponents specifically 10 which is the most common number to have an exponent with you can look at the exponent and that number is the amount of zeros. So in this question there is 10 to the zeroth power. The amount of zeros would be zero so it is actually 1.
So then 10 to the zeroth power is equivalent to 1. The problem then becomes this: 38.7 / 1 which obviously equals 38.7
2. As I explained earlier, 10 to the first power would be 10 because the exponent number is one so that means the amount of zeros is one.
Equation: 38.7 / 10 which to solve you need to move the decimal to the left which gives you the answer, 3.87
3. The exponent number is 2 so, 10 to the second power is 100.
Equation: 38.7 / 100
Move the decimal to the right twice and it will give you the answer .387
Please note that when multiplying by powers of 10 you move the decimal point to the left and when dividing by powers of ten you move the decimal to the right.

In a carnival game, there are six identical boxes, one of which contains a prize. A contestant wins the prize by selecting the box containing it. Before each game, the old prize is removed and another prize is placed at random in one of the six boxes. Is it appropriate to use the binomial probability distribution to find the probability that a contestant who plays the game five times wins exactly twice
Answer:
The probability that a contestant who plays the game five times wins exactly twice is [tex]16.08[/tex] %
Step-by-step explanation:
We will use binomial theorem here
[tex]C_{n,k}p^k(p')^{n-k}[/tex]
Substituting the available values in above equation, we get
[tex]C_{5,2} * \frac{1}{6}^2*\frac{5}{6}^3[/tex]
[tex]0.1608[/tex]
OR
The probability that a contestant who plays the game five times wins exactly twice is [tex]16.08[/tex] %
The flux hotel recently installed a triangular pool as shown below. If the hotel manager needs to order a cover for the pool and the cost is $35 per square foot, how much can he expect to spend?
Answer:
[tex]Total = \$6545[/tex]
Step-by-step explanation:
Given
[tex]Base = 17ft[/tex]
[tex]Height = 22ft[/tex]
[tex]Slant\ Height = 32ft[/tex]
[tex]Cost = \$35[/tex] per square ft
Required
Determine the expected spending
First, calculate the area of the pool.
[tex]Area = \frac{1}{2} * Base * Height[/tex]
[tex]Area = \frac{1}{2} * 17ft * 22ft[/tex]
[tex]Area = 17ft * 11ft[/tex]
[tex]Area = 187ft^s[/tex]
The total cost is:
[tex]Total = Cost * Area[/tex]
[tex]Total = 35 * 187[/tex]
[tex]Total = \$6545[/tex]
