The probability of 150 flips and 84 tails would be 84/66 or 56 percent
The equation of the line that passes through the points (7, 450) and (14, 401) is y + 7x = 499
<h3>How to find equation of a line?</h3>
The equation of a line can be represented as follows:
y - y₁ = m(x - x₁)
where
Therefore, (7, 450)(14, 401)
m = 401 - 450 / 14 - 7 = -49 / 7 = -7
Therefore, using (7, 450)
y - 450 = -7(x - 7)
y - 450 = -7x + 49
y + 7x = 49 + 450
y + 7x = 499

Apply the fraction rule:
2x x 1/4
Multiply the numbers: 2x 1 =2
2x/4
Factor the number: 4=2 x2
2x/ 2 x 2
Cancel the common factor: 2
Answer: x/2
Answer:
The vertex is (2,1)
Step-by-step explanation:
ƒ(x) = –x^2 + 4x – 3
Factor out the negative
= -(x^2 -4x+3)
Factor
What 2 numbers multiply to +3 and add to -4
-3*-1 = 3
-3+-1 = -4
f(x) = -( x-3)(x-1)
Find the zeros
0 = -( x-3)(x-1)
0 = x-3 0 = x-1
x=3 x=1
The x value of the vertex is 1/2 way between the two zeros
(3+1)/2 = 4/2 =2
To find the y value, substitute x=2 in
f(2) = -( 2-3)(2-1)
=-(-1)(1) = 1
The vertex is (2,1)
