Answer:

-4

Step-by-step explanation:

Use the equation for slope.

m=\frac{y_{2}-y_{1}  }{x_{2}- x_{1} }\\m=\frac{-4 - 8 }{2-(-1) }\\m=\frac{-4 - 8 }{2+1 }\\m=\frac{-12}{3}\\ m=-4

The slop is -4.

Answer:

-4

Step-by-step explanation:

The slope of a line given two points is given by

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

   = (-4-8)/(2 - -1)

   = (-4-8)/(2+1)

   = -12/3

   = -4

alexdok [17]

Answer:

P(120< x < 210) =  0.8664

Step-by-step explanation:

given data

time length = 20 year

average mean time μ = 165 min

standard deviation σ = 30 min

randomly selected game between = 120 and 210 minute

solution

so here probability between 120 and 210 will be

P(120< x < 210) = P(\frac{120-165}{30}< \frac{x-\mu }{\sigma }

P(120< x < 210) = P(\frac{-45}{30}< \frac{x-\mu }{\sigma }

P(120< x < 210) = P(-1.5< Z < 1.5)

P(120< x < 210) = P(Z< 1.5) - P(Z< -1.5)

now we will use here this function in excel function

=NORMSDIST(z)

=NORMSDIST(-1.5)

P(120< x < 210) = 0.9332 - 0.0668

P(120< x < 210) =  0.8664
