Answer: b and d

Step-by-step explanation:

Since the roots are x=2 and x=6, we can write the equation as

$f(x)=a(x-2)(x-6)$

Substituting in the coordinates of the vertex,

$-4=a(4-2)(4-6)\\\\-4=a(2)(-2)\\\\-4=-4a\\\\a=1$

So, the equation is $f(x)=(x-2)(x-6)$ .

On expanding, we get $f(x)=x^2 - 8x+12$

Step-by-step explanation:

g. (1/4 + 1/2) = 3/4

3/4 ÷ 3/2 = 1/2

h. (1/5 - 1/2) = 3/10

3/10 ÷ 3/5 = 1/2

I. (2/5 ÷ 5/6) = 12/25

12/25 × 7/8 = 21/50

A coin tosses 100 times 52 heads and 48 tail what is the probability of flipping a tail on the coin

Pie

Answer:

The answer is 48/100 or 12/25

Step-by-step explanation:

Since there is 48 tails and 100 times flipped the answer would be 48/100 and if you ask for the probability of flipping the heads that would be quite the same and its 52/100. So the <u><em>ANSWER IS 12/25</em></u>.
