Distance between 2 points
\( = \sqrt{(x1 - x2)^{2} + (y1 - y2)^{2} } \)
☆ (x₁, y₁) is the first coordinate while (x₂, y₂) I'd the second coordinate.
Length of RS
\( = \sqrt{ {[ - 1 -( - 4)] }^{2} + (9 - 1)^{2} } \\ = \sqrt{( - 1 + 4)^{2} + 8^{2} } \\ = \sqrt{ {3}^{2} + 64 } \\ = \sqrt{73} \\ = 8.54 \: (3 \: s.f.)\)

the number of accidents in a certain city is modeled by a poisson random variable with average rate of 10 accidents per day. suppose that the number of accidents in different days are independent. find the approximate probability that there will be more than 3800 accidents in a certain year. assume that there are 365 days in a year.
Answers
The approximate probability that there will be more than 3800 accidents in a certain year is 0.0063.
We are given that;
Rate of accidents =10
Days= 365
Now,
Plugging in the values of μ and σ, we get:
P(σY−μ>σ3800−μ)=P(60.41Y−3650>60.413800−3650)
Simplifying, we get:
P(60.41Y−3650>60.413800−3650)=P(60.41Y−3650>2.49)
Let Z be a standard normal random variable. Then we have:
P(60.41Y−3650>2.49)=P(Z>2.49)
To find this probability, we can use a normal table or a calculator. Using a calculator, we get:
P(Z>2.49)≈0.0063
Therefore, by probability the answer will be 0.0063.

The value of the system in which newton's law of motion is applicable is (a) 25 (b) 10 (c) if output is x , 4y -x-15 =0
What about newton's law of motion?
Newton's laws of motion are three fundamental laws in classical physics that describe the behavior of objects in motion. They were first presented by Sir Isaac Newton in his work "Philosophiee Naturalis Principia Mathematica" in 1687. The three laws are:
The Law of Inertia: An object at rest will remain at rest, and an object in motion will continue in a straight line with constant velocity, unless acted upon by an external force.The Law of Acceleration: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, F = ma, where F is the net force, m is the mass of the object, and a is the acceleration.The Law of Action-Reaction: For every action, there is an equal and opposite reaction. This means that when an object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.According to the given information:
a) When input is 10.
output= 10×4 - 15 =25
b) From the question output is 25
Because input* 4 -15= output. So (output +15) / 4= input
so input =\((25+15)/4\) =10
c) if output is x. So y × 4 - 1 5 = x , 4y - x - 15 = 0

Joanne wants to buy a dishwasher. The dishwasher costs £372. Joanne will pay a deposit of £36. She will then pay the rest of the cost in 4 equal monthly payments. How much is each monthly payment?
Answers
Answer:
£84
Step-by-step explanation:
The total cost of the dishwasher is: £372
The deposit she makes is: £36
Thus, she still has to pay the following amount:
£372 - £36 = £336
And this amount will be divided into 4 equal monthly payments. So, we must divide the amount that she still has to pay by 4.
Each one of this monthly payments will have a value of:
£336 ÷ 4 = £84
the answer is that each monthly payment will be of £84

9Step-by-step explanation:
Just multiply the numerator together using a calculator (for ease) then multiply the denominators including the powers. Once you did this part properly you should get,
531441/59049
= 9
3^8 x 3^4 is 3^8+4= 3^12 (this is the numerator)
3^2x3^8 is 3^ 2+8= 3^10 (this is the denominator)
Now since there is a division bar we obviously have to divide the numerator: 3^12 by the denominator: 3^10. [Remember division requires subtraction of powers] therefore:
3^12 \ 3^10 = 3^12-10
= 3^2. (=9)
And is not given as 9 since it is not in index form therefor answer is 3 power of 2 (3^2)

Which is the initial value that shrinks an exponential growth function by 50%? One-fifth One-fourth One-third One-half
Answers
Answer:
One-half
Step-by-step explanation:
Given
Exponential function
Required
The initial value that shrinks the function by \(50\%\)
An exponential function is represented as:
\(y = ab^x\)
Where the growth function is:
\(r = b^x\)
\(a \to\) initial value
For the growth function to shrink by x%, then:
\(a =1 - x\%\)
In this case; x = 50. So, we have:
\(a =1 - 50\%\)
Express as fraction
\(a =1 - \frac{50}{100}\)
Take LCM
\(a =\frac{100 -50}{100}\)
\(a =\frac{50}{100}\)
Reduce fraction
\(a =\frac{1}{2}\)

Answer:
Step-by-step explanation:
Discussion
The numbers on each die are 1 to 6.
They are all equally likely to turn up. There are 36 possibilities in all 6*6
So getting a 10 can be done in 3 ways.
6 + 4 = 10
4 + 6 = 10
5 + 5 = 10
You can't get 10 any other way.
So of the 36 ways of throwing 2 dice, only 3 will work.

What is probability?
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.
