The probability would be zero that both the pirate and the captain hit each other's ships.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Captain Ashley has probability 1/2 of hitting the pirate ship.
Dread pirate Umaima has a 1/3 probability of attacking the Captain's ship if it hasn't already.
The captain must miss if the pirate hits, and the requirement that both hits are not satisfied. The requirement that both hits cannot be satisfied if the pirate misses.
Therefore, the probability would be zero that both the pirate and the Captain hit each other's ships.

Miss Tyrrell catches the 9:45am bus from Leeds to London.
The distance between the two cities is 195 miles.
The bus travels at an average speed of 52 mph.
What time should she arrive in London?
Answer:
The time she would arrive in London is 1:20 pm
Step-by-step explanation:
Recall
Speed= Distance/Time
But we want to find the time taken, so:
We cross multiply:
Speed *Time = Distance
Make time the subject of formula
Time= Distance/Speed
195/52
= 3.75 hours
Therefore, 9:45 am + 3.75 hours
= 13.20 pm
Which is equivalent to 1:20 pm

if the pressure in the right tire is found to be 22 psi, what is the probability that the left tire has a pressure of at least 25 psi?
Considering the given probability distribution, we have that there is a 0.349 = 34.9% probability that the left tire has a pressure of at least 25 psi.
What is the probability distribution?The probability distribution for the air pressure of the tires of the car(X right, Y left) is given as follows:
f(x,y) = K(x² + y²), 18 ≤ x ≤ 28, 18 ≤ y ≤ 28.f(x,y) = 0, otherwise.The pressure in the right tire is found to be 22 psi, hence y = 22 and:
f(x,y) = K(x² + 484), 18 ≤ x ≤ 28.f(x,y) = 0, otherwise.The value of K is found considering that the sum of all probabilities has to be 1, hence:
[tex]\int_{18}^{28} K(x^2 + 484) dx = 1[/tex]
[tex]\frac{Kx^3}{3} + 484Kx\lbracket|_{x = 18}^{x = 28} = 1[/tex]
Applying the Fundamental Theorem of Calculus:
7317.33K + 13552K - 8712K - 1944K = 1
10213.33K = 1
K = 1/10213.33
K = 0.000098.
The probability that the left tire has a pressure of at least 25 psi is:
[tex]P(X \geq 25) = \int_{25}^{28} 0.000098(x^2 + 484) dx[/tex]
[tex]P(X \geq 25) = 0.000098\int_{25}^{28} (x^2 + 484) dx[/tex]
[tex]P(X \geq 25) = 0.000098\left(\frac{x^3}{3} + 484x\right)_{x = 25}^{x = 28}[/tex]
[tex]P(X \geq 25) = 0.000098(7317.33 + 13552 - 5208.33 - 12100)[/tex]
[tex]P(X \geq 25) = 0.349[/tex]

I WILL CHOOSE THE BRAINLIEST ANSWER!!! What is the area of the backyard that the grass takes up?
The area of the backyard that the grass takes up is 34x² - πx². The correct option is B. 34x² - πx²
Calculating areaFrom the question, we are to determine the area of the backyard that the grass takes up
Area of the backyard that the grass takes up
= Area of the backyard - Area of the rectangle pool deck - Area of the circle pool
Area of the backyard = 6x × 6x
= 36x²
Area of the rectangle pool deck = 2x × x
= 2x²
Area of the circle pool = πx²
Thus,
Area of the backyard that the grass takes up = 36x² - 2x² - πx²
Area of the backyard that the grass takes up = 34x² - πx²

Solve the system by elimination 2x - y = 1 and x - 2y = -1
Answer:
x = 1 and y = 1
Step-by-step explanation:
Let's solve your system by elimination.
2x − y = 1 and x − 2y = −1
Multiply the second equation by -2, then add the equations together.
(2x−y=1)
−2(x−2y=−1)
Becomes:
2x−y=1
−2x+4y=2
Add these equations to eliminate x:
3y=3
Then solve3y=3for y:
3y=3
3y3=33(Divide both sides by 3)
y=1
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:

If f(x + 3) = x^2 + 4x − 7, find f(2).
The complete statement is that if the equation of the function f(x + 3) = x^2 + 4x − 7, the value of the function f(2) is -10
What are quadratic equations?Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
How to determine the solution to the quadratic equation?A quadratic equations can be split to several equations and it can be solved as a whole
In this case, we have
f(x + 3) = x^2 + 4x − 7
To find f(2), we make use of the following comparison
f(2) = f(x + 3)
This means that
2 = x + 3
Evaluate
x = -1
Substitute x = -1 in f(x + 3) = x^2 + 4x − 7
f(-1 + 3) = (-1)^2 + 4(-1) − 7
This gives
f(2) = -10
Hence, the complete statement is that if the equation of the function f(x + 3) = x^2 + 4x − 7, the value of the function f(2) is -10

x meters =
4x meters =

(Type integers or decimals.)
4x meters
(8x - 3) meters
x meters
The sides of the triangle are as follows:
a = 43 meters
b = 172 meters
c = 341 meters
Given, we have the perimeter of the triangle as 556 meters.
The sides of the triangle are:
a = x meters
b = 4x meters
c = (8x - 3) meters.
we know that perimeter of the triangle = a + b + c
therefore, a + b+ c = Perimeter
x + 4x + (8x - 3) = 556
x + 4x + 8x - 3 = 556
13x - 3 = 556
13x = 556 + 3
13x = 559
x = 559/13
x = 43
hence we get the value of x as 43.
substitute x value in the sides of the triangle to get the orignal values of the sides.
a = x = 43 meters.
b = 2x = 4 × 43 = 172 meters.
c = 8x - 3 = 8(43) - 3 = 341 meters.
Hence the sides of the triangle are 43 meters , 172 meters and 341 meters.

wire 19 cm long is cut into two pieces. the longer piece is 3 cm longer than the shorter piece. find the length of the shorter piece of wire
The shorter piece of wire is 8 cm long when the total length of the wire is 19 cm long.
We are given that:
a wire's length is 19 cm.
We have to cut the wire into two pieces.
We are also given that the longer piece of wire is 3 cm longer than the shorter piece.
Let the shorter piece of wire be x cm
Longer piece = x + 3 cm.
So, the equation formed will be:
x + x + 3 cm = 19 m
2 x + 3 cm = 19 cm
2 x cm = 19 cm - 3 cm
2 x cm = 16 cm
x = 16 / 2 cm
x = 8 cm.
Therefore, the shorter piece of wire is 8 cm long.

The midpoint of segment EF is M(4, -1). Find endpoint F if the other endpoint E is at E(2, 3).
The x and y coordinates of the endpoint F are (6,-5)
The midpoint of a line segment is a point that is situated exactly at the middle from the two ends of the line segment
The coordinate of the mid-point or any other point can be found using the section formula.
For a point P with coordinates, the section formula is as follows: (x,y)
which divides the line segment A(x1,y1), B(x2,y2) in the ratio m:n, is given by the equation
Px=mx2+nx1/m+n Py=my2+ny1/m+n
Because the midpoint divides the line segment equally, m and n are both 1 in the midpoint case.
Thus the formula becomes
Px=1*x2+1*x1/1+1 Py = 1*y2+1*y1/1+1
where Px and Py are x and y co-ordinates of the point x and y
It is now assumed that midpoint M has coordinates (4,-1)
Point E is given by (2,3)
We are required to find F
Thus using section formula,
Mx=2+x/2 My=-3+y/2

If 25% of a number is 75 and 35% of the same number is 105, find 10% of that number.
Answer:
30
Step-by-step explanation:
to find 10%, find 100% first
because we know what 25% is, the easiest way we can work this out is multiply 25% by 4
so:
[tex] 4 \times 25\% = 100\%\\\\ 75 \times 4 = 300[/tex]
this means that 100% is 300.
now to find 10% all we have to do is divide the number by 10.
[tex]300 \div 10 = 30[/tex]
so 10% is 30
to check we're right, we make sure that 25% and 10% = 35%
75 + 30 = 105, meaning our percentages are correct
