The spinner shown is divided into 8 equal sections. What is the probability that the arrow will land on a section labeled with a
Oxana [17]

The probability of the arrow will land on a section labeled with the number greater than 3 is \frac{5}{8}

Step-by-step explanation:

Given,

The spinner is divided into 8 sections say named 1, 2, 3, 4, 5, 6, 7, 8

To find the P : probability of the arrow will land on a section labeled with the number greater than 3

Formula

<u>P = (the number of possible outcomes) ÷ ( the number of total result)</u>

We will count the probability when the arrow land on either 4 or 5 or 6 or 7 or 8 = 5 times

Total number of result = 8

Hence the probability = \frac{5}{8}

Find the equation of a line that contains the points (−3,−1) and (−4,−7). Write the equation in slope-intercept form
BARSIC [14]

Answer:

y =6x+17

Step-by-step explanation:

First we need to find the slope

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

   = (-7- -1)/(-4 - -3)

   = (-7+1)/(-4+3)

   -6/-1

   6

The slope intercept form of the equation is

y = mx+b  where m is the slope and b is the y intercept

y = 6x+b

Substitute a point into the equation

-1 = 6(-3) +b

-1 = -18+b

Add 18 to each side

17 =b

The equation is

y =6x+17
