Answer:
Step-by-step explanation:
The factored form of a quadratic is given by:
Where <em>p</em> and <em>q</em> are the zeros, and <em>a</em> is the leading coefficient.
The quadratic relation has zeros of 5 and 6, and it has a y-intercept of 30.
Since the zeros are 5 and 6, <em>p </em>and <em>q</em> are 5 and 6. Thus:
The y-intercept is 30. In other words, when <em>x </em>= 0, <em>f(x)</em> = 30:
Solve for a:
Therefore, our quadratic in factored form is:
To find the standard form, expand:
Answer:
Probability is 64%
Step-by-step explanation:
Given the smaller circle which is shaded whose radius is denoted by r and the largest circle whose radius is denoted by R
r = 3 inches
R = 5 inches
Step 1 : To calculate the area of shaded region.
Area of circle =
⇒ Area =
= square inches
Step 2 : To calculate the area of larger circle.
Area of circle =
⇒ Area =
= square inches
Step 3 : Calculate the probability that a point chosen from shaded region
Probability = Area of shaded region/Area of larger circle.
= /
=
= 0.36 = 36%
Step 4 : calculate the probability that a point chosen inside the larger circle is not in shaded region.
Probability = 1 - 0.36
= 0.64 = 64%
Hence the probability is 64%
