Allushta [10]

Answer:

The average speed is 9.8 meter per second in the first two seconds

Step-by-step explanation:

Complete Question

What is the average velocity of the rock in first 2 secs?

Solution

Distance travelled in first two seconds

$4.9 t^2 = 4.9*2*2 = 19.6$ m

Average speed = $S2-S1/2 = 19.6-0/2 = 9.8$ meter per second

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 72.6 Mbp

Lapatulllka [165]

Answer:

a. 54.05 Mpbs.

b. 2.745... standard deviations.

c. The z-score is 2.745....

d. The carrier's highest data speed is significantly high.

Step-by-step explanation:

a. The difference between the highest measured data speed and the mean is 72.6 - 18.55 = 54.05 Mbps.

b. The amount of standard deviations of 54.05 Mbps is equal to this value divided by the standard deviations, so we yield $\frac{54.05}{19.69} = 2.745...$ standard deviations.

c. The z-score is equal to the difference between the mean and a data point in standard deviations, so the z-score is 2.745....

d. 2.745... is not between -2 and 2, so the carrier's highest data speed is not insignificant - so it's significantly high.
