Police response time to an emergency call is the difference between the time the call is first received by the dispatcher and th

e time a patrol car radios that it has arrived at the scene. Over a long period of time, it has been determined that the police response time has a normal distribution with a mean of 6.4 minutes and a standard deviation of 1.7 minutes. For a randomly received emergency call, find the following probabilities.
a) between 5 and 10 min.

Answer:

  B.

Step-by-step explanation:

b is a long vector directed to the upper right. 1/3 of that will be a short vector (1/3 the length of b). When it is subtracted, its opposite is added. The vector diagram showing the subtraction will have a shorter vector directed to the lower left. Its tail will be at the nose of 2a. Only diagram B fits this description.

Simplify 1/x-3+4/x divided by 4/x-1/x-3
Alchen [17]
The answer is \frac{5x-12}{3x-12}

The expression is: \frac{ \frac{1}{x-3}+ \frac{4}{x}  }{ \frac{4}{x} - \frac{1}{x-3} }

Let's factorize it:
\frac{ \frac{1}{x-3}+ \frac{4}{x}  }{ \frac{4}{x} - \frac{1}{x-3} } = \frac{ \frac{x*1}{x(x-3)}+ \frac{4*(x-3)}{(x-3)*x}}{ \frac{(x-3)*4}{(x-3)*x}- \frac{x*1}{x*(x-3)}}= \frac{ \frac{x+4(x-3)}{x(x-3)} }{ \frac{4(x-3)-x}{x(x-3)} }

Since \frac{ \frac{a}{b} }{ \frac{c}{d} }= \frac{a}{b}/ \frac{c}{d}= \frac{a*d}{b*c}, then:
\frac{ \frac{x+4(x-3)}{x(x-3)} }{ \frac{4(x-3)-x}{x(x-3)} }= \frac{(x+4(x-3))*x(x-3)}{(4(x-3)-x)*x(x-3)}

Cancel x(x-3) and simplify:
\frac{(x+4(x-3))*x(x-3)}{(4(x-3)-x)*x(x-3)} = \frac{x+4(x-3)}{4(x-3)-x} = \frac{x+4x-12}{4x-12 -x} = \frac{5x-12}{3x-12}

Describe the steps you used to solve the equation and find the amount of Carrie’s allowance.
Sidana [21]
Multiply each of the fractions by 1 to get them to have the same denominator.
1/4 x 3/3 = 3/12
1/3 x 4/4 = 4/12
New Equation:
3/12a + 4/12a + 8 = 22
now add up similar terms
7/12a + 8 = 22
subtract 8
7/12a = 14
multiply each side by your denominator
12(7/12)a=12(14)
7a=168
divide by 7
a = 24
