What is the equation of this trend line? Enter your answers by filling in the boxes.

zhuklara [117]

Answer:

$k=-2j+24$

Step-by-step explanation:

Take two points from the graph

(0,24) and (6,12)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{k2-k1}{j2-j1}$

substitute

$m=\frac{12-24}{6-0}$

$m=\frac{-12}{6}=-2$ ---> is negative because is a decreasing function

Find the equation of the line in slope intercept form

$k=mj+b$

we have

$m=-2\\b=24$

Note: The y-intercept is given (0,24)

substitute

$k=-2j+24$

A spinner is broken into section labeled 1 to 38. What is the probability that.On your next spin, that you will spin a 1?

VashaNatasha [74]

Answer:

1/38

Step-by-step explanation:

Given :

Probability = required outcome / Total possible outcomes

Total possible outcomes = total Numbe rod sections = 38

Required outcome = number of 1's on the entire section = 1

Hence, the probability of spinning a one equals :

P(spinning a 1) = 1 / 38

I Need The Answer Plz Geometry Is Hard!!

tensa zangetsu [6.8K]

Answer:

6.0.

Step-by-step explanation:

The line marked 20 is 2 times the line marked 3x - 8 (because the last line cuts the 2 sides of the large triangle in 2).

2(3x - 8) = 20

6x - 16 = 20

6x = 36

x = 6.0.
