Answer:

- 25

Step-by-step explanation:

Step 1:

3/5m = - 15      Equation

Step 2:

m = - 15 ÷ 3/5     Divide

Step 3:

m = - 15/1 × 5/3       Multiply

Answer:

m = - 25

Hope This Helps :)

Answer:

m=-25

Step-by-step explanation:

To solve, make the variable "m" by itself. To do that, multiply the fraction "5/3" (or divide 3/5) to both sides.

3/5(5/3)m=-15(5/3)<--- 3/5 and 5/3 are reciprocals and cancel out. -15 times 5/3 equals -25.

m=-25

Answer:

y = -4/3x +4

Step-by-step explanation:

6y + 8x = 24

Subtract 8x from each side

6y + 8x-8x = -8x+24

6y = -8x+24

Divide each side by 6

6y/6 = -8x/6 +24/6

y = -4/3x +4

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:

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.

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.

Your Answer will be:

The ship from the shore is 250 Km away by most direct path.

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.

Answer:

Domain: {  3 , 4 , 5 , 6 }

Range:  { 0 , 1 , 2 , 3 }

Step-by-step explanation:

The domain is the set of all the values of  x . The range is the set of all the values of  y .

The range is set of all y values so the range is {0,1,2,3}.

For the domain, it's the set of all x values.

The Answer is

2059.0 and (2000,50,9)---------------------------

Answer:

Consider one of eight positions separately from all others. There are 10 possible ways to choose

a digit to place on this position since there are ten digits from 0 to 9, and this choice is

independent of all other positions since each digit can be repeated and there is no restriction on

how to choose digits.

So, we have 8 positions and each one is filled by a digit in 10 ways independently from each other,

therefore the total number of possible codes equals to ways it can be done for each independent

position multiplied altogether. This is 10 × 10 × … × 10 = 108

(100 million).

Answer: 108 different codes.

Answer:

the first one is 713/100

the second one is a reapeating decimal

Step-by-step explanation:

Answer:

Step-by-step explanation:

We observe that first differences of the given numbers are ...

  10 -3 = 7

  24 -10 = 14

  52 -24 = 28

That is, each difference is 2× the previous one. This suggests an exponential relation that has a base of 2.

We notice that doubling a term doesn't give the next term, but gives a value that is 4 less than the next term. So, we can get the next term by doubling the previous one and adding 4.

Then our recursive relation is ...

  f[1] = 3 . . . . the first term

  f[n] = 2×f[n-1] +4 . . . . double the previous term and add 4

The next term is 2·52 +4 = 108.

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
