A circular running track is 1/4 mile long. Jamie runs on this track, completing each lap in 1/20 of an hour. What is Jamie’s run

Grace [21]

Answer: The running speed of Elena is 5 miles/hour and this can be determined by using the formula of speed.

Step-by-step explanation:

A circular running track 1/4 is a mile long.

Elena runs on this track, completing each lap in 1/20 of an hour.

Speed formula is used to determine the speed of Elena. The formula of speed is given by:

----- (1)

where S is the speed, D is the distance and T is the time taken by Elena to run a circle.

Now, put the value of distance D and time T in the equation (1).

Speed = 5 miles/hour

Therefore, the running speed of Elena is 5 miles/hour.

Suppose the number of residents within five miles of each of your stores is asymmetrically distributed with a mean of 25 thousan

ohaa [14]

Answer:

$P(\bar X\:>27.8\:thousand)=3.07\%$

Step-by-step explanation:

Since the number of residents within five miles of each of your stores is asymmetrically distributed, the distribution of the sample means will be approximately normal with a mean of 25 thousand.

The standard deviation of the sample means is:

$\sigma_X=\frac{\sigma}{\sqrt{n} }$

$\implies \sigma_X=\frac{10.6}{\sqrt{50} }=1.4991$

The z value is $z=\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n}} }$

We plug in the values to get:

$z=\frac{27.8-25}{1.4991}=\frac{2.8}{1.4991}=1.87$

The area to the right of 1.87 is $1-0.96926=0.03074$ .

The probability that the average number of residents within five miles of each store in a sample of 50 stores will be more than 27.8 thousand is 3.07%

Review the graph of complex number z.

vredina [299]

9514 1404 393

Answer:

$6\sqrt{2} (\cos(135^{\circ})+i\sin(135^{\circ}))$

Step-by-step explanation:

The angle to the point in the second quadrant is measured from the positive real axis (the x-axis). Second quadrant angles are between 90° and 180°, leaving the 135° choices as the only ones that make sense.

The magnitude of z is the root of the sum of the squares of its components:

|z| = √((-6)^2 +6^2) = 6√2

So, the polar form of z is ...

$\boxed{6\sqrt{2} (\cos(135^{\circ})+i\sin(135^{\circ}))}$

this matches the first choice
