0
Step-by-step explanation:
We are told that if the Captain's ship has been hit, he will always miss and since the pirate is shooting first, the captain's ship could be hit. So the probability that both of them hit each other's ship is 0 because if the pirate hits the Captain's ship, he will always miss. 1/2 * 0 = 0
There is no way for both of them to hit each other's ships because if their ships have been hit, they will always miss.

Kip walks 5/9 mile in 5/8 hour. What is kips rate of speed? How far can kip walk in one hour?
Step-by-step explanation:
5/8 hr = 5/9 mile
1 hr = 5/9 ÷ 5/8
= 8/9 mile
Speed = distance / time
= 5/9 mile / 5/8 hr
= 8/9 miles per hr?

A ship left shore and sailed 240 kilometers east, turned due north, then sailed another 70 kilometers. How many kilometers is the ship from shore by the most direct path?
Your Answer will be:
The ship from the shore is 250 Km away by most direct path.
What is Pythagoras theorem?The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
Given:
Base= 240
Perpendicular= 70
so, distance between ship from shore by the most direct path
= √70² + 240²
=√ 4900+ 57600
= √62500
= 250
Hence, The ship from the shore is 250 Km away by most direct path.

Mr. Wagner is on a diet. He currently weighs 250 pounds. He loses 3 pounds per month. Write an equation that represents his weight after m months. After how many months will Mr. Wagner reach his goal of 220 pounds.
Answer:
y=mx+b
Step-by-step explanation:
In this case, x is represented by m. B is how much he weighs at the start which is 250. How many pounds does he lose per month ? 3. Thus, we conclude:
220=3x+250
Answer:
10 months
Step-by-step explanation:
220+3m = 250
Subtract 220 from both sides, now it is 3m=30. So now divide 3 on both sides. So now we have our answer m=10.
(Geometry: area of a regular polygon)
A regular polygon is an n-sided polygon in which all sides are of the same length and all angles have the same degree (i.e., the polygon is both equilateral and equiangular). The formula for computing the area of a regular polygon is
area = (n * s^2) / (4 * tan(PI / n)
Here, s is the length of a side. Write a program that prompts the user to enter the number of sides and their length of a regular polygon and displays its area.
Sample Run
Enter the number of sides: 5
Enter the side: 6.5
The area of the polygon is 72.69017017488385
ANSWER SHOULD BE IN PYTHON CODING
Answer:
Follows are the python code to this question:
import math as m #import package
n=int(input('Enter the number of sides:'))#defining n variable for input number of side
s= float(input('Enter the side: '))#defining s variable for input side value
area = (s*s *n)/(4 * (m.tan(m.pi/n)))#defining formula for calcaulting area
print (area)#print area
Output:
please find the attached file.
Step-by-step explanation:
In the above code, firstly, we import the math package as m, and after that, two-variable "n and s" is defined, which uses for input integer and float value from the user end.
In the next step, we use the area formula that is already in the question.In this formula, we modify some value and put the user input into the area formula, and print its value.

Step-by-step explanation:
[tex]\frac{2}{3}x + 6 = 9[/tex]
2/3 of x is (2/3x)
6 added to that makes it (2/3 +6).
Saying this is 9 means it is equal to 9.
2/3x +6 = 9

a random sample of 21 students from the U and at A&T were surveyed about their music listening habits. Their responses (in hours, each square represents 0.5 hour) were recorded and displayed using the following histograms. The left represents U. The right represents SHSAT. Which data set(U or SHSAT students) has a larger standard deviation? Explain.
Answer: U
Step-by-step explanation:
Looking at the graphs, U is skewed right and SHSAT is more of a normal distribution. Generally, this means the standard deviation would be greater for the data set that is skewed.
Let's find the standard deviation for each data set to confirm our theory.
Step 1) Find the mean number of hours
Step 2) Subtract each data value from the mean
Step 3) Find the mean of Step 2
U
hours x frequency: 1(3) + 2(5) + 3(4) + 4(3) + 5(3) + 6(2) + 9(1) = 72
Step 1: mean = (hours x frequency)/frequency = 72/21 = 3.4
Step 2: 2.4(3) + 1.4(5) + 0.4(4) + 0.6(3) + 1.6(3) + 2.6(2) + 5.6(1) = 33.2
Step 3: standard deviation = (sum from step 2)/ frequency = 33.2/21 = 1.58
SHSAT
hours x frequency: 1(1) + 2(3) + 3(4) + 4(5) + 5(3) + 6(3) + 7(2) = 86
Step 1: mean = (hours x frequency)/frequency = 86/21 = 4.1
Step 2: 3.1(1) + 2.1(3) + 1.1(4) + 0.1(5) +0.95(3) + 1.9(3) + 2.9(2) = 28.5
Step 3: standard deviation = (sum from step 2)/ frequency = 28.5/21 = 1.36
The calculations confirm that U has the greater standard deviation

Mr. Ratchett, an elderly American, was found murdered in his train compartment on the Orient Express at 7 AM. When his body was discovered, the famous detective Hercule Poirot noted that Ratchett had a body temperature of 28 degrees. The body had cooled to a temperature of 27 degrees one hour later. If the normal temperature of a human being is 37 degrees and the air temperature in the train is 22 degrees.
Required:
Estimate the time of Ratchett's death using Newton's Law of Cooling.
Answer: Mr. Ratchett died approximately at 2AM.
Step-by-step explanation: Newton's Law of Cooling shows the cooling rate between a body and the environment, by stating that the rate is proportional to the difference in temperatures between them.
Mathematically, it is represented as:
[tex]\frac{dQ}{dt}=\alpha.A.(T_{s}-T)[/tex]
This differential equation solved, gives the solution:
[tex]T(t)=T_{s}+(T_{0}-T_{s})e^{-kt}[/tex]
where
[tex]T_{s}[/tex] is temperature of the environment
[tex]T_{0}[/tex] is the initial temperature of the body
k is a parameter dependent of heat transfer coefficient, heat capacity and area of the body
t is time required to change the temperature
For the murder on the Orient Express, first determine parameter k.
In 1 hour, Mr. Ratchett's body decrease 1°:
[tex]27=22+(28-22)e^{-1k}[/tex]
[tex]5=6e^{-k}[/tex]
[tex]e^{-k}=\frac{5}{6}[/tex]
[tex]ln(e^{-k})=ln(0.834)[/tex]
k = 0.1823
Using the parameter, find estimate time:
[tex]28=22+(37-22)e^{-0.1823t}[/tex]
[tex]6=15e^{-0.1823t}[/tex]
[tex]ln(e^{-0.1823t})=ln(0.4)[/tex]
0.1823t = 0.9163
[tex]t=\frac{0.9163}{0.1823}[/tex]
t ≈ 5 hours
The body was found at 7AM. So, it took approximately 5 hours to cool down to 28° at that time. Therefore, Mr. Ratchett died at 2AM.
show your work : 17-8n=-2(4n-7)-3
Answer:
i think so
Step-by-step explanation:
17‒8n=‒2(4n‒7)‒3
17‒8n=‒8n+14‒3(add ‒17 on both sides)
‒8n=‒8n+14‒3‒17
‒8n=‒8n‒6
‒8n+8n=‒6
0=‒6
so the equation doesn't have solution
