You throw the bowling ball at the pins.You have two throws to knock down ten pins.
Procedure
The events are not independent. Before the first throw, there will be 10 pins to knockdown. Let the number of pins knocked down in the first throw is x.
In the second throw, there will not be 10 pins to knockdown. The number of pins to knockdown in the second throw depends on the number of pins being knocked down in the first throw. Hence, the number of pins to knockdown in the second throw is (10 - x). Thus, the events are dependent

Make x the subject of m=n+x/p
Step-by-step explanation:
m = n + x/p
to make x the subject means to transform this into an equation, where we have x alone on one side being expressed by the other terms.
e.g.
x = ...
remember, when we change one side of an equation, we have to do the same thing to the other side as well. otherwise the equation relation is broken. it is like a balance that we need to keep in balance.
so,
m = n + x/p | subtract n from both sides
m - n = x/p | multiply both sides by p
(m - n)p = x
or
x = (m - n)p
because it is an essential property of an equation relation that
a = b means that also b = a

Each of Polina's juice pouches holds 7 fluid ounces of juice. A equation that connects the quantity of juice in each pouch to the overall amount in fluid ounces is p-7j=0.
Given that,
Each of Polina's juice pouches holds 7 fluid ounces of juice.
We have to create a equation that connects the quantity of juice in each pouch (p) to the overall amount (j) in fluid ounces.
The equation is p=7j
p-7j=0

The value of the missing length √5
What Pythagoras Theorem?
The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a key relationship in Euclidean geometry between a right triangle's three sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Given,
Hypotenuse = 3cm
One side = 2cm
Let the one side given be Base
Then, base = 2cm
Now, by Pythagoras Theorem we can find out the missing length or Perpendicular of the triangle
By Pythagoras Theorem:
H² = P² + B²
If we have to find perpendicular then,
P² = H² - B²
or,
P = √H² - B²
Putting the values we get,
P = √(3)² - (2)²
P = √(9 - 4)
P = √(5)
P = √5
Hence, The missing length of the triangle is √5

A rectangular sheet of paper is folded at the corner. Find the value of x.
Value of x is 66°.
Define angle.Based on measurement, there are many kinds of angles in geometry. The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation. A geometrical shape called an angle is created by connecting two rays at their termini. In most cases, an angle is expressed in degrees.
Given Data
A rectangular sheet of paper is folded at the corner.
Right triangles characterize both the folded-over region and its void. In the bottom left corner, there is a right angle that is marked at 33 degrees. Thus,
180-(33+90)
= 180-123
= 57° is what is left.
The angles in the triangle that has been folded over are the same.
To the left of x, there are two angles that meet at a straight angle. The sum of all right angles is 180 degrees. The 57° measure is shared by the two angles that make up the straight angle with x. This results in:
180-(57+57)
= 180-114
= 66°
Value of x is 66°.

0 x>12
0 x<12
O
x<18
O x>16
The expression of the possible values of the number is x < 16
How to determine the possible values of the number?The statement is given as
Eight less than four times a number is less than 56.
Rewrite the statement as an expression
So, we have
4 * number - 8 is less than 56
Represent the number with x
So, we have
4 * x - 8 is less than 56
This gives
4 * x - 8 < 56
Add 8 to all sides
4 * x < 64
Divide both sides by 4
So, we have
x < 16
Hence, the number is all numbers less than 16

y 6 4 7 9
The equation which represent the relationship between x and y is x = 3y.
Given that:-
x 18 12 21 27
y 6 4 7 9
We can see that,
When x = 18, y = 6
Hence, 18 = 3*6
Hence,
x = 3y
Similarly,
When x = 12, y = 4
Hence, 12 = 3*4
Hence,
x = 3y
When x = 21, y = 7
Hence, 21 = 3*7
Hence,
x = 3y
When x = 27, y = 9
Hence, 27 = 3*9
Hence,
x = 3y
Hence, by observing all the data given in the question, we can say that,

Indian cricket team won 4 more matches than it lost with NewZealand. If it won 3/5 of its matches
,how many matches did India play?
As per the unitary method, the number of matches did India play is 20.
Unitary method:
Unitary method is the method in which we first find the value of a unit quantity and then use it to find the value of any required quantity.
Given,
Indian cricket team won 4 more matches than it lost with New Zealand.
Consider If it won 3/5 of its matches, then we need to find the number of matches did it played.
Let us consider the number of matches lost = x
Number of matches won = x + 4
Therefore, the total matches played
=> x + x +4
=> 2x + 4
So, we know that, it won 3/5 th of the matches,
Then it can be written as,
=> x + 4 = 3/5 (2x +4)
Cross multiply it,
=> 5(x + 4) = 3(2x + 4)
=> 5x + 20 = 6x + 12
=> x - 8 =0
=> x = 8
Then the total number of matches played by India is,
=> 2(8) + 4
=> 16 + 4
=> 20.
Therefore, 20 matches are played by India.

The perimeter of the triangle below is 89 units. Find the length of side BC.
Write your answer without variables.
Answer:
BC = 10 units
Step-by-step explanation:
Perimeter of triangle:Perimeter = Sum of all sides
y + 1 + 4y + 5y - 2 = 89 units
y + 4y + 5y + 1 - 2 = 89
Combine like terms,
10y - 1 = 89
Add 1 to both sides,
10y = 89 + 1
10y = 90
Divide both sides by 10,
y = 90 ÷ 10
y = 9 units
BC = y + 1
= 9 + 1
= 10 units

Key: 12|5 = 125
Part A: Describe the shape of each data set. (4 points)
Part B: Wyatt analyzed the data and stated that the better measure of center for the seniors is the mean. Is Wyatt correct? Explain your reasoning. (5 points)
Part C: Wyatt decided there are no outliers in the juniors' data set. Is he correct? Justify your answer mathematically. (5 points)
Considering the given stem-and-leaf plot for the distribution, it is found that:
a. The shape of each data-set is:
Juniors: Right-skewed.Seniors: Left-skewed.b. Due to the skewed distribution, the best measure is the median, and Wyatt is not correct.
c. Since all the values are within 1.5IQR of the first and of the third quartile, there are no outliers in the distribution and Wyatt is correct.
Stem-and-leaf plotThe plot lists all the measures in the data-set, following the format of the key, as follows:
4|5 = 45.
Hence, the Junior measures are:
112, 121, 125, 132, 134, 135, 146, 156, 195, 200.
The Senior measures are:
123, 166, 172, 175, 183, 186, 191, 194, 197, 201.
To classify the shape of the distribution, we need to find the mean and the median.
For the Juniors, these measures are given as follows:
Mean: 145.6.Median: 134.5.As the mean is greater than the median, the distribution is skewed to the right.
For the Seniors, these measures are given as follows:
Mean: 178.8.Median: 184.5.As the median is greater than the mean, the distribution is skewed to the left.
For item b, in skewed distributions we should use the median as the measure of center, hence Wyatt is not correct.
For item c, the quartiles of the Junior's data-set is given by:
Q1: 123.Q3: 175.5.Hence the interquartile range IQR is given by:
175.5 - 123 = 52.5.
Then the bounds of non-outlier values are given by:
123 - 1.5 x 52.5 = 44.25.123 + 1.5 x 52.5 = 201.75.All the measures are in this range, hence there are no outliers.

In other words, it is a relationship where the value of the entire is always assumed to be 100.A percentage is a ratio or fraction where the full value is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test. In ratio form, it is expressed as 30:100 and in fraction form as 30/100.Amount charged =$850
