What is the slope of (-8, 2) and (1, -4).

Airida [17]

Answer:

-2/3

Step-by-step explanation:

To find the slope of two points

m = (y2-y1)/ (x2-x1)

= (-4-2)/(1--8)

= (-4-2)/(1+8)

= -6/9

Lie on a strought

Elenna [48]

Answer:

25°

Step-by-step explanation:

In $\triangle BCD$

BD = CD .....(Given)

$\implies m\angle CBD = m\angle BCD$

(By isosceles triangle theorem)

$m\angle BCD = 60\degree....(given)$

$\implies m\angle CBD = 60\degree$

Now,

$m\angle CBD + m\angle ABD= 180\degree$

(Angles in linear pair)

$\implies 60\degree + m\angle ABD= 180\degree$

$\implies m\angle ABD= 180\degree - 60\degree$

$\implies m\angle ABD= 120\degree$

Next, in $\triangle ABD$

$m\angle BAD + m\angle ABD+ m\angle ADB= 180\degree$

(By interior angle sum postulate of a triangle)

$\implies 35\degree + 120\degree+ x= 180\degree$

$\implies 155\degree+ x= 180\degree$

$\implies x= 180\degree-155\degree$

$\implies x= 25\degree$

7. 2+ 32 = 5+ 3z

SVETLANKA909090 [29]

Answer:

$z=9\frac{2}{3}$

Step-by-step explanation:

2 + 32 = 5 + 3z

34 = 5 + 3z

3z + 5 = 34

3z + 5 - 5 = 34 - 5

3z = 29

3z ÷ 3 = 29 ÷ 3

$z=9\frac{2}{3}$

romanna [79]

<span>Standard deviation shows the distribution present in a set. Range can be used to approximate this property. Therefore, Set b (100, 140, 150, 160, 200 10, 50, 60, 70, 110) has the largest standard deviation because it has a range of 190 (i.e. 200 - 10)</span>

PLZ HELP!!! 20 POINTS!!!

dangina [55]

$Answer: \\ Since \: \widehat{SRT} = \widehat{STR} \: \\and \: \widehat{RTU} = \widehat{STR} + \widehat{STU} = 180^{\circ} \\ \Rightarrow \widehat{SRT} + \widehat{STU} = 180^{\circ} \\ \Leftrightarrow 4x - 20 + 6x = 180 \\ \Leftrightarrow10x = 200 \\ \Leftrightarrow x = 20 \\ \widehat{SRT} = 4 \times 20 - 20 = 60^{\circ}$
