P(2 or H) = P(2) + P(H) - P(2 and H)  

What is the probability of getting a 2 P(2)?  = 1/6

What is the probability of getting heads P(H)?  = 1/2

P(2 and H) is the product of those two events since the events are independent. = 1/6 * 1/2 = 1/12

P(2 or H) = P(2) + P(H) - P(2 and H)  

P(2 or H) = 1/6 + 1/2  - 1/12 = 7/12

tekilochka [14]

Answer:

<h2>           y - 2 = -⁶/₅x</h2>

Step-by-step explanation:

The point-slope form of the equation of the line passing point <em>(x₁, y₁)</em> and with the slope of <em>m</em> is:  y - y₁ = m(x - x₁)

m = -⁶/₅

Y-Intercept = 2  ⇒  point (0, 2)  ⇒  x₁ = 0,  y₁ = 2

Point-Slope Form:  <u>  y - 2 = -⁶/₅(x - 0)</u>

What is the value of a in this function’s equation?
bazaltina [42]

Answer:

a=-10/9

Step-by-step explanation:

vertex=(0,10)  (h,k)

y=a^2x+bx+c

y=c=10 when x=0

the x intercepts are (0,3) and (0,-3)

y=a (x-h)^2+k

y=a(x-0)+10

y=ax^2+10

find a  at point (3,0)

y=a(3)^2+10

0=9a+10

9a=-10

a=-10/9

y=-10/9 x^2+10

check with points(-3,0)

0=-10(-3)^2/9+10

0=-90+90=0 correct
