The largest possible value for the probability of A4 is 0.3.
If events A1, A2, A3, and A4 are pairwise mutually exclusive with the exception that A1 and A2 occur simultaneously, then the probability of A1 and A2 occurring together is 0.1. This means that the probability of A1 occurring separately is 0.3 - 0.1 = 0.2, and the same is true for A2.
Since A1, A2, A3, and A4 are pairwise mutually exclusive, the probability that they all occur together is 0. Therefore, the sum of their individual probabilities is also 0. Therefore, the probability of A4 is the remaining probability after accounting for the probability of A1, A2, and A3. The largest possible value for the probability of A4 is the total probability minus the probability of A1, A2, and A3.
So, the largest possible value for the probability of A4 would be:
1 - (0.2 + 0.2 + 0.3) = 1 - 0.7 = 0.3
Therefore, the largest possible value for the probability of A4 is 0.3.

[tex]\sf =\dfrac{(7+y)(7-y)}{6y(y + 7)}=\dfrac{(7+y)(7-y)}{6y(7+y)}\\\\\\=\dfrac{7-y}{6y}[/tex]
y² - 10y + 21

Bicycles in the late 1800s looked very different than they do today.

a. How many rotations does each tire make after traveling 600 feet? Round your answers to the nearest whole number.
Note that where the diameter of the bicycles are 60 inches and 9 inches respectively, the rotation of each tire after traveling 600 feet would be:
Small Tire (9in Diameter ) = 188.4 Rotations.
Big Tire (60 in Diameter) = 3.2 rotations
Note that the above were arrived at using the knowledge of Circumference.
What is the circumference of a circle?Note that the circumference in geometry is the perimeter of a circle or ellipse.
This is calculated using the formula:
C = 2πr
or
C = πD
Where C = Circumference
R = radius
D = Diameter which is 2r
π = 3.14
To arrive at how many rotations each tire did, we'd have to divide the distance traveled by the circumference of each tire.
For the Small Tire, the diameter is 9 feet.
Thus, the circumference of Small Tire = 3.14 * 9
= 28.26 feet
Thus, the rotations by the small tire is:
600/28.26
= 21.2314225053
[tex]\approx[/tex] 21.2feet
Applying the same process to the big tire, we have:
C = 3.14 * 60
C = 188.4
The rotations by the big tire =

= 3.1847133758

Thus, the rotations by each tire over 600ft is given as:

what is the value of x in 12 ( x + 10 ) = 24
also explain
Answer: x = -8
Step-by-step explanation:
12 ( x + 10 ) = 24
First we divide the two sides of the exercise by 12.
[tex]\boldsymbol{\sf{x+10=\dfrac{24}{12} }}[/tex]
We divide 24 by 12..
x + 10 = 2
Subtract 10 from both sides.
x = 2 - 10
Subtract 10 from 2 to get. Since the number 10 is greater than 2, the result will be negative.
x = -8
Answer:
[tex] \sf \: x = - 8[/tex]
Step-by-step explanation:
Given equation,
→ 12(x + 10) = 24
Now the value of x will be,
→ 12(x + 10) = 24
→ 12(x) + 12(10) = 24
→ 12x + 120 = 24
→ 12x = 24 - 120
→ 12x = -96
→ x = -96 ÷ 12
→ [ x = -8 ]
Hence, the value of x is -8.
a jet travels 2964 miles against the wind in 4 hours and 3564 miles with the wind in the same amount of time. what is the rate of the jet in still air and what is the rate of the wind?
The rate of the jet in still air is 741 mph, and the rate of the wind is 150 mph.
What is rate ?
A rate is a ratio of two quantities, typically a change in one quantity over a corresponding change in another quantity, often over a specific time period. For example, the interest rate on a loan is the ratio of the interest paid to the amount of the loan. A speed is a rate at which an object covers distance, velocity is a rate of change of position, etc.
To find the rate of the jet in still air:
Rate = Distance / Time
The distance is 2964 miles, and the time is 4 hours. So the rate of the jet in still air is:
Rate = 2964 / 4 = 741 mph
To find the rate of the wind, you can use the formula:
Wind Rate = (Distance with wind - Distance against wind) / Time
The distance with the wind is 3564 miles, the distance against the wind is 2964 miles, and the time is 4 hours. So the rate of the wind is:
Wind Rate = (3564 - 2964) / 4 = 600 / 4 = 150 mph
So the rate of the jet in still air is 741 mph, and the rate of the wind is 150 mph.

the meaning of the rate of change in the context of this problem? Show all work.
The rate of change in this context refers to the change in the value of p, specifically between the peak and closing.This allows us to understand how much p changes on average between these two points in time.
What is the meaning of the rate of change in the context of this problem?It is a measure of how quickly or slowly the value of p is changing over time.
By calculating the average rate of change, we can understand the overall trend of the value of p and whether it is increasing or decreasing at a steady rate or if there are fluctuations.
This information can be useful for understanding the performance of a stock or investment, as well as predicting future trends.
Additionally, the rate of change can also help to identify any potential issues or opportunities within the market.
Overall, the rate of change provides a clear picture of the stock's performance over a certain period of time.
To calculate the average rate of change of p between peak and closing, we need to find the difference in p values (p(14) - p(8)) and divide that by the difference in time (14 - 8).
p(14) - p(8) = ? - ? = ?
(14 - 8) = ?
The average rate of change of p is ?/6.
The meaning of the rate of change in the context of this problem is the average change in the value of p per unit of time.
In this case, we are looking at the average change in p between the peak and closing, and expressing that change as a ratio of p(14) - p(8) to (14 - 8). This allows us to understand how much p changes on average between these two points in time.

Step-by-step explanation:
First you have to graph your y-intercept (1) *which is the red dot in the graph I made for you*
Then you must use your slope (-2) to graph the rest
Since your slope is negative you have to go down from your y-intercept. In your case you are going down 2 units from your intercept. And since your slope is a whole number instead of a fraction you just go to the right 1 unit to make the coordinate (1,-1).
That is how you graph your equation.

Formula to find the probability of an event:
"P(A) = n(A) / n(S)
where, n(A) is the number of favorable outcomes of an event A
n(S) is the total number of outcomes for an experiment"
"Information available from the question"
Total number of students are,
n(S) = 10 + 16
n(S) = 26
Let event A: selecting first stick with a boy name
n(A) = 16
So, the probability of a boy is,
P(A) = n(A)/n(S)
P(A) = 16/26
P(A) = 8/13
if the first stick is not replaced, then n(S) would be,
26 - 1 = 25
Let event A: selecting first stick with a boy name
n(B) = 10
So, the probability of a boy is,
P(B) = n(B)/n(S)
P(B) = 10/25
P(B) = 2/5

The set of mobile gaming apps in which the number of monthly users was greater than 12 million is {A, B}
How to find the set of mobile gaming apps with monthly users greater than 12 million?A set is a collection of distinct objects, called elements or members, that are brought together by a common property or rule.
Sets can be represented using set notation, which uses curly brackets {} to enclose the elements of the set. For example, the set of natural numbers less than 5 can be represented as {1, 2, 3, 4}.
The set of mobile gaming apps in which the number of monthly users was greater than 12 million can be determined by checking given the table for mobile gaming apps with value greater than 12 million.
You will notice that only A and B have values greater than 12 million. That is 23 million and 13 million for A and B respectively.
Thus, the set will be {A, B}

Mary ran 1 3/5 miles on Monday and 7 1/5 miles on Tuesday. How many times her Monday’s distance was her Tuesday’s distance?
Mary's Tuesday distance is 1/8 times her Monday distance
How to calculate the number of Mary's Tuesday distance that is her Monday's distance?
On Monday Mary ran 1 3/5 miles
= 8/5
On Tuesday Mary ran 1/5 miles
Therefore the number of times her Tuesday distance was her Monday distance can be calculated as follows
1/5 ÷ 8/5
= 1/5 ×5/8
= 1/8
Hence her Tuesday distance was 1/8 times her Monday distance

whats the parallel equation and perpendicular?
The equations of the lines are
Parallel lines: y = 4/3x + 2 and y = 4/3x - 2Perpendicular line: y = -0.75x + 8.5How to determine the equationsThe parallel lines
We have the points to be
(3, 6) and (0, 2)
A linear equation is represented as
y = mx + c
Where
c = y when x = 0
So, we have
y = mx + 2
Using the points, we have
6 = 3m + 2
So, we have
3m = 4
Divide
m = 4/3
So, the equation is
y = 4/3x + 2
For the other parallel line, we have
y = 4/3x - 2
Perpendicular line
The slopes of parallel and perpendicular lines are opposite reciprocals
So, we have
m = -3/4
This gives
y = -3/4x + c
We have the point to be (0, 8.5)
So, we have
y = -3/4x + 8.5
y = -0.75x + 8.5
