Police response time to an emergency call is the difference between the time the call is first received by the dispatcher and th
Marizza181 [45]

Answer:

\mu = 8.8\\\sigma = 1.9

Now we are supposed to find probabilities that the response time is between 5 and 10 minutes i.e P(5<x<10)

Formula : z= \frac{x-\mu}{\sigma}

at x = 5

z= \frac{5-8.8}{1.9}

z=-2

at x = 10

z= \frac{10-8.8}{1.9}

z=0.6315

P(-2<z<0.6315)=P(z<0.6315)-P(z<-2)

Refer the z table

P(-2<z<10)=0.7357-0.0228=0.7129

So, the probability that response time is between 5 and 10 minutes  is 0.7129

b)the response time is less than 5 minutes

at x = 5

z= \frac{5-8.8}{1.9}

z=-2

P(x<5)=P(z<-2)=0.0228

So, the probability that  the response time is less than 5 minutes is 0.0228

c)the response time is more than 10 minutes

at x = 10

z= \frac{10-8.8}{1.9}

z=0.6315

P(x>10) = 1-P(x<10) = 1-P(z<0.63) = 1-0.7357 = 0.2643

So, The probability that  the response time is more than 10 minutes is 0.2643

A circle is divided into 9 equal parts. What is the angle measured of two of those parts?What is the degrees
Anika [276]

Answer:

Angle of 1 part: 40°

Angle of 2 parts: 80°

Step-by-step explanation:

Angles in a circle / Equal parts of a circles = Angle of 1 part

360/9 = 40°

40 x 2 = 80

Write the standard form of the line that passes through the point (-2, 4) and is parallel to x - 2y = 6. Type your answer in the
san4es73 [151]
Rewrite the equation: 2y=x-6, y=x/2-3, so slope is 1/2 which is also the slope of the parallel line.
It will have the equation y=x/2+a where a is found by plugging in the given point: 4=-1+a, so a=5.
Therefore y=x/2+5. (This can also be written 2y=x+10 or x-2y+10=0)
