107,600 115,220 104,910 median, mode, mean

san4es73 [151]

Answer:

1. Mean = 342.7 (Rounding to the nearest tenth)

2. Median = 167.5

3. Mode = There isn't a mode for this set of numbers because there isn't a data value that occur more than once.

Step-by-step explanation:

Given this set of numbers: 107, 600, 115, 220, 104, 910, find out these measures of central tendency:

1. Mean = 107 + 600 + 115 + 220 + 104 + 910/6 = 342.7 (Rounding to the nearest tenth)

2. Median. In this case, we calculate it as the average between the third and the fourth element, this way:

115 + 220 =335

335/2 = 167.5

3. Mode = There isn't a mode for this set of numbers because there isn't a data value that occur more than once. All the data values occur only once.

A space vehicle deploys its re-entry parachute when it's traveling at a vertical velocity of -150 meters/second (negative becaus

Arlecino [84]

The initial velocity is -150m/s.
Remember that:
V(t) = Vi + at, where v(t) is velocity at time t, Vi is initial velocity, and a is acceleration.
We know that the vehicle stopped after 30 seconds, so V(30) = 0.
Let's plug the useful info into our function and solve for a:
0 = -150 + a*30 Add 150 to both sides
150 = 30a Divide both sides by 30
a = 5 m/s²
The average acceleration is 5 meters per second squared.
