Let us calculate the median; the 6th observation is 20, so it is 20. We need the 6th observation so that out of the 11 observations we have 5 above the median and 5 below (or equal). We also have that then Q1 is the median of the lowest 5 observations, hence 19 (14,16,19,19,20, the 3rd observation is 19). Similarly, we get that the median for the upper half of the observations, Q3 namely, is 22 (21,21,22,22,23, the 3rd observation is 22). Thus, the interquartile range is 3=Q3-Q1. According to our calculations, all observations are wrong.

12. What is the value of x?

Vanyuwa [196]

Answer:

$x=3.75\ units$

Step-by-step explanation:

we know that

$(AE)(EB)=(CE)(ED)$ ----> by Intersecting Chords Theorem

substitute the given values

$(6)(5)=8x$

solve for x

$x=\frac{30}{8}$

$x=3.75\ units$

Datguy323 is going to complain again. What's the variables for: <img src="https://tex.z-dn.net/?f=x%5E2%2By%5E2%3D29%5C%5Cx%2By%

Korolek [52]

Answer: :o I FINALLY MADE IT

(5, 2)

x = 5

y = 2

Step-by-step explanation:

First, I graphed both equations. They meet at the points (5,2) and (2,5). Because y < 5, the solution is (5, 2)

Hope it helps <3

What is the equation of the sinusoid shown in the graph?

ololo11 [35]

Answer:

Answer: C

Step-by-step explanation:

The Cosine Function

The graph of a cosine function is a sinusoid that starts at its maximum value of 1 at x=0 and takes x=2π radians to complete a full cycle. The function of the parent cosine function is:

$y=\cos x$
