Check Your Understanding Are you more likely to win a random drawing if you crinkle the paper that contains your name before putting it into the drawing box? A curious student conducted a study to investigate. The student took 100 equal sized slips of paper and crinkled 25 of them before putting them all into a box. After mixing well, they asked an uninformed person to select a winner at random. The student noted if the slip was crinkled. The slip was returned to the box, mixed well, and asked another uninformed person to select a winner at random. This process was repeated 10 times. Let Y = the number of times that a crinkled paper was selected.
Answer: hello your question to the given scenerio is missing below is the missing question
question: Does this setting represent a Binomial distribution ?
answer : Yes the setting represents a Binomial distribution
Step-by-step explanation:
The setting represents a Binomial distribution, because the criteria's for a Binomial distribution is all present which are
The random variable ( number of times a crinkled paper is picked ) is represented as Y Each sample is drawn independently and with replacement there are only two outcomes ( success or failure )Number of trials is given as 10 probability of success = 25 / 100 = 0.25yes, this setting represent the binomial distribution.
Given that,
The student took 100 equal sized slips of paper and crinkled 25 of them before putting them all into a box.
After mixing well, they asked an uninformed person to select a winner at random.
We have to determine,
Does this setting represent a Binomial distribution.
According to the question,
Let Y = the number of times that a crinkled paper was selected.
The setting represents a Binomial distribution, because the criteria's for a Binomial distribution is all present .
These are the points which represents the given representation is a binomial distribution.
The random variable ( number of times a crinkled paper is picked ) is represented as Y.
Each sample is drawn independently and with replacement.
There are only two outcomes ( success or failure ).
Number of trials is given as 10 times repeated.
The probability of the success,
[tex]Probability\ of \ success = \dfrac{25}{100} = 0.25[/tex]
Hence, yes this setting represent the binomial distribution.

Mackenzie made 38 of 50 free throws. What is the
experimental probability that Mackenzie will NOT
make the next free throw she attempts?
A- 6/25
B- 12/25
C- 19/25
D- 21/25
A I believe because Against the odds of 38/50 would be 12/50 that is not an option so split in half this would be A cause its an equivalent fraction
Which set of side lengths or angle measures can be used to construct a triangle A. 50 inches, 90 inches, 35 inches B. 60 inches, 25 inches, 95 Inches C. 45,45,80 D. 60, 45,75
Answer:
D. 60, 45,75
Step-by-step explanation:
For options C and D
For a triangle the sum of the angles must always be equal to 180 degrees
So 180 ≠45+45+80
and
60 +45+ 75= 180
For option A and B
The length of the longer side is equal to the square root of the sum of squares of the other two sides in a triangle.
According to Pythagorus theorem
hypotenuse²= base² + perpendicular²
c²= a²+ b²
90²= 50² + 35²
8100= 2500+1225
8100≠3725
95²= 60²+ 25²
9025= 3600+ 625
9025≠4225
Therefore only D is the correct option
PLEASE HELP!!!
Give an example showing why one of the methods is not correct.
Answer:
Brandon's methot is not correct
for example: x=9 9×1/2=4.5
Here's why:
Let's use his method to find the square root of 36. That means we multiply 36 by 1/2 = 0.5 to get 36*0.5 = 18; however, 18 is not the square root of 36. We can see that 18*18 = 324. Instead, the square root of 36 is 6 because 6*6 = 36.
As another example, let's say we want to find the square root of 64. With Brandon's method, we would get to 64*0.5 = 32, but 32*32 = 1024. Ashley's method is correct and 8*8 = 64 shows that 8 is the square root of 64.
As a visual approach, think of a square with side lengths 8 feet each. The area would be 8*8 = 64 square feet. If you didn't know the side length, but you knew that the area was 64 square feet, then you could apply the square root operation to find the side length to be 8 feet (or you could effectively use Ashley's guess-and-check method to arrive at 8 feet). In short, the square root operation is the opposite of squaring a number. We consider these inverse operations.
Multiplying by 1/2 is the same as dividing by 2. Division is the opposite of multiplication, and division is not the inverse of squaring a number. It's just a coincidence that Brandon's method happened to work on the value 4. But as shown earlier, it doesn't work in general.
When three squares are joined at their vertices to form a right triangle, the combined area of the two smaller squares is the same as the area of the largest square. Which three squares will support this statement?
Answer:
J
Step-by-step explanation:
Area of a square = L x W
F:
(5 x 5) + (4 x 4) = 81
25 + 16 = 81
41 = 81 INCORRECT =( X
H:
64 + (5 x 5) = (13 x 13)
64 + 25 = 169
89 = 169 INCORRECT =( X
G:
(6 x 6) + (5 x 5) = (7 x 7)
36 + 25 = 49
61 = 49 INCORRECT =( X
J:
144 + (5 x 5) = 169
144 + 25 = 169
169 = 169 CORRECT =)

Step-by-step explanation:
You have to add 2 to the other side and shade to the left because it’s less than 18.
Answer:
Letter E
Step-by-step explanation:
To solve this, all you need to do is add two to both sides to isolate the x, and that will result in x ≤ 18. In a number line, it is a closed circle (because it has the line below the sign), and it points to the left because it is less than or equal to.

Answer:
You need to use the angles as a waypoint such as the one opposite b is equal to b then you need to use the angles on a straight line
Step-by-step explanation:
Answer:
∠A= 111.75°
Step-by-step explanation:
Please see the attached picture.
∠B +∠C= 180° (adj ∠s on a str. line)
(x +35)° +∠C= 180°
∠C= 180° -(x +35)°
∠C= 145° -x°
∠A= ∠C (corr. ∠s)
∠A= 145° -x°
Given that ∠A is (3x +12)°, equate this expression to the expression we found.
145° -x°= 3x° +12°
3x° +x°= 145° -12°
4x°= 133°
x°= 133° ÷4 (÷4 on both sides)
x°= 33.25°
Substitute the value of x back into the expression for ∠A:
∴∠A= 3(33.25°) +12°
∠A= 111.75°

factorise x squared - 3x
Answer:
x squared -3× =x(x-3)
Step-by-step explanation:
Since the common factor is x,one comes out to multiply the other to give it x squared and since one x has been written outside already we just write the 3 so that when we multiply it we will get the answer we were asked to factorise

When a farmer harvests apples he expects 6% of the apples to be rotten how many apples would the farmer expect to be rotting when harvesting apples
The question is incomplete had the number of harvested apples isn't given.
Answer:
0.06n
Step-by-step explanation:
When a farmer harvests apples he expects 6% of the apples to be rotten how many apples would the farmer expect to be rotting when harvesting apples
The expected percentage of rotten apples when harvesting = 6%
The expected number of rotten apples can be obtained by taking the product of the expected percentage and the number of apples to be harvested.
Since the number of harvested apples isn't given,
Let the number of harvested apples = n
Therefore, the expected number of rotten apples will be :
6% * n
0.06n
Note : you can easily substitute the actual number of harvested apples for n in the equto get the actual answer
