A outlier is something spread out from the rest for example you have the numbers 12, 9, 3,10, 16, 89 obviously the outlier is 89 so the number spread from the rest

An outlier is a valve. It is much smaller or larger than most of the other valves in a set of data.

I need some help with this

masya89 [10]

Answer:

A, C, D

Step-by-step explanation:

Consider triangles NKL and NML. These triangles are right triangles, because

$m\angle K=m\angle M=90^{\circ}$

In these right triangles:

$\overline{NL}\cong \overline {NL}$ - reflexive property;
$\angle KLN\cong \angle MLN$ - given

Thus, triangles NKL and NML by HA postulate. Congruent triangles have congruent corresponding parts, so

$\overline{KN}\cong \overline{NM}\\ \\\overline{KL}\cong \overline{LM}\ [\text{option D is true}]$

Since

$\overline{KN}\cong \overline{NM},$

then

$7x-4=5x+12\\ \\7x-5x=12+4\\ \\2x=16\\ \\x=8\ [\text{option A is true}]\\ \\MN=KN=7\cdot 8-4=56-4=52\ [\text{option C is true}]$

Option B is false, because KN=52 units.

Option E is false, because LN is congruent KN, not LM

write and solve an equation to show thw average number of calendars her 3rd period class sold peer week during the four week cha

kari74 [83]

If they sold 89 calendars over 4 weeks, the 'equation' would look like (x = average calendars sold over 4 weeks):
$x = \frac{89}{4}$

If you solve it, you get:
$22 \frac{1}{4}$

Which is equal to 22.25. Hope this helps!
