Answer:

Option d (convenience sample) is the right solution.

Step-by-step explanation:

  • An unlikely sample wherein the investigator chooses such individuals closest and therefore most approachable for the particular investigation, would be termed as a Convenience sample.
  • It's a way to gather information or data with the use of sampling advantageously positioned around a place or broadband internet.

The altitude (i.e., height) of a triangle is increasing at a rate of 2 cm/minute while the area of the triangle is increasing at
s344n2d4d5 [400]

Answer:

A = 1/2 B H       area = 1/2 base X height

B = 2 A / H = 2 * 99 / 12 = 16.5 cm

dA / d t = 1/2 * (B dH / dt + H dB / dt)

dB / dt = (2 dA / dt - B dH / dt) / H

dB / dt = (2 * 1.5 cm^2 / min - 16.5 cm * 2 cm / min) / 12 cm

dB / dt = (3 - 33) / 12 cm/min = -2.5 cm/min

What do the differences between the points (as shown on the graph) represent?
artcher [175]
The first one 7/2 represents the change in y over change in x.

For those kinds of questions I would refer to the change in y over change in x method.

Bullet 3 would work because 7/2 doesn’t result to 1. So that’s not the answer.

I hope that helps
