Answer:

$\frac{1}{2}$

Step-by-step explanation:

Given

tan x = $\sqrt{3}$ , then

x = $tan^{-1}$ ( $\sqrt{3}$ ) = 60° ← related acute angle

Since 180° < x < 270° and tan x > 0 then x is in third quadrant

x = 180° + 60° = 240°

and

sin(x - 210)°

= sin(240 - 210)°

= sin30°

= $\frac{1}{2}$

Will mark as brainliest :)! Suppose that there were a strong correlation between the variables d and t.

Sonbull [250]

Answer:

Step-by-step explanation:

A strong correlations shows evidence of a relationship between the two quantities. It does not necessarily indicate that a change in one variable is causing a change in the other one. There MAY be a causal relationship, but the correlation, by itself, does not prove that.

First arrange in ascending order:

16, 16, 18, 19, 21, 25, 27, 30, 34, 49, 50, 58, 59, 71, 75.

There are a total of 15 numbers, so the median is the 8th number = 30.

The lower quartile is halfway alone the first 7 numbers which is the 4th number and it is 19.

The median which is the middle number
