What is the first quartile, Q1, of the following distribution?

Mathematics

3 0

Answer:

26.5

Step-by-step explanation:

the median is 37 due to there being 17 data points in the set. So the first quartile wouldn't contain 37 so you find the other point. The point is in between 26 and 27, so you add those 2 points together and divide it by 2 to get your answer.

Lets get started :)

We need to isolate t from x = \frac{1}{2}at²

Take 2 to the left-hand side { Do multiplication since you see division }
2x = at²

Take a to the left-hand side { Do division since you see multiplication }
\frac{2x}{a} = t² 

Take square root since t is to the power of 2
\sqrt{ \frac{2x}{a} } = t

Can someone help me with number 10? Thank you.

Answer:

  • east 95 km
  • south 89 km

Step-by-step explanation:

SOH CAH TOA can remind you of the relationships between triangle measures. The distance east is the side of the right triangle that is opposite the angle, so is related to the hypotenuse (ship's travel distance) by the sine function.

  sin(43°) = (travel distance)/(distance east)

So, ...

  (distance east) = (travel distance)·sin(43°)

Likewise, the cosine function can be used to find the distance south.

Then we have ...

  east = (130 km)sin(43°) ≈ 95 km

  south = (130 km)cos(43°) ≈ 89 km
