This is a simple velocity question.

Keep in mind that: (distance/time)=velocity.

So, we can write a very simple equation:

(262.5/3.5)=Speed/Velocity

Dividing, we find out that the car's average speed is 75 miles per hour.

Answer:

Slope: \frac{3}{5}

Y-Intercept: (0,-5)

Step-by-step explanation:

1. To find the slope, we need to have the equation in slope-intercept form, which is y=mx+b. In this case, our equation is already in this form. m is what your slope is. In this case, our

2. To find the y-intercept we look at value b that is in y=mx+b. In this case, b is -5. So, our ordered pair is (0,-5).

Petra jogs 5 miles in 40 minutes. At this rate, how long would it take her to jog 7 miles?
Wittaler [7]
(40 min)/(5 mi) = (time)/(7 mi) . . . . . the rates are the same
(7/5)*(40 min) = time = 56 min

At the same rate, it would take Petra 56 minutes to jog 7 miles.

A local grocery store chain has a sushi stand. That sushi stand makes samples for store customers to entice customers to purchas
Liula [17]

Answer: 0.99822

Step-by-step explanation:

Our inter-arrival time follows Poisson distribution with parameter 14 which is in hour so first we have to calculate this in minutes as we have to calculate probability in minutes.

So converting 14 into minutes will give  \frac{14}{60}=0.233

Let X=inter-arrival time between two customers

and here \lambda = 0.233

Probability(X is less than or equal to 2 minutes) = P(X=0) + P(X=1) + P(X=2)

Now the Poisson distribution has PDF = \frac{\exp ^{-\lambda }\times \lambda ^{X}}{X!}

So P(X = 0) = \frac{\exp ^{-0.233}\times 0.233^{0}}{0!} = 0.79215

P(X= 1) = \frac{\exp ^{-0.233}\times 0.233^{1}}{1!} = 0.18457

P(X=2) = \frac{\exp ^{-0.233}\times 0.233^{2}}{2!} = 0.02150

Now adding all three probability gives =  0.79215 +0.18457 + 0.02150=0.99822
