You spin a spinner divided into 6 equal sections and then flip a coin. if the spinner lands on 8, what is the probability that the coin will land heads up?
a. 0
b.1/8
c.1/6
d.1/2

1/2(i think)

Step-by-step explanation:

since a coin has two sides

the denominator would be 2

since the coin has 1 chance of it landing on heads and 1 chance of it landing on 2

the probability the coin will land on heads is 1/2

hope this helps!

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

answer: c

(2, -4)

goes 7 to the

(9, 4)
