Complete the equation of the graphed linear function. Write the slope in decimal form.
erma4kov [3.2K]

Every straight line graph has an equation in the same form:

             y  =  (slope of the line) x  +  (y-intercept) .


-- The slope of the line is

     (how far it goes UP, going left to right between any 2 points)
divided by
     (how far it goes left to right between the same 2 points) .

The line on this graph has a slope of  + 1/2 .


-- The y-intercept is the point where the line crosses the y-axis.
The line on this graph crosses the y-axis at  -1 .

                       y  =  (slope of the line) x  +  (y-intercept) .                     

                       y  =      ( 0.5 ) x                            ( - 1 ) .

Sue has one spin of the circular spinner shown below.
VARVARA [1.3K]

Answer:

Colour | Probability

YELLOW | 0.20

WHITE | 0.18

GREEN | 0.12

RED | 0.18

BLUE | 0.32

Step-by-step explanation:

The complete question is presented on the attached image to this solution.

From the image of the spinner and the given probabilities, the combination of YELLOW, WHITE and GREEN make up exactly half of the total space on the spinner.

0.2 + 0.18 + 0.12 = 0.50

Then, BLUE and RED make up the other half of the spinner.

Probability of landing on either BLUE or RED = 1 - 0.50 = 0.50

Let P(BLUE) = x and P(RED) = y

x + y = 0.50

Two of the lines shown on the diagram are diameters of the circle.

The first line that is a diameter splits the circle into two parts; (WHITE, YELLOW, GREEN) and (RED, BLUE).

From here, we have established that x + y = 0.50

The other line that is a diameter splits The circle into two part; (WHITE, BLUE) and (YELLOW, GREEN, RED)

From this other information,

P(WHITE) + P(BLUE) = 0.50

0.18 + x = 0.50

x = 0.50 - 0.18 = 0.32

P(YELLOW) + P(GREEN) + P(RED) = 0.50

0.20 + 0.12 + y = 0.50

y = 0.50 - 0.32 = 0.18

To check, x + y = 0.32 + 0.18 = 0.50 (Correct!!)

Hope this Helps!!!
