Answer:

C

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (8, - 14), thus

y = a(x - 8)² - 14

To find a substitute (5, 13) into the equation

13 = a(5 - 8)² - 14

13 = a(- 3)² - 14

13 = 9a - 14 ( add 14 to both sides )

27 = 9a ( divide both sides by 9 )

a = 3

Thus

y = 3(x - 8)² - 14 → C

Use the spinner below to find the probability of getting the following number after 1 spin. P(multiple of 3) = (Round to 4 decim
Talja [164]

The value of the probability P(multiple of 3) is 0.3333

<h3>How to determine the probability?</h3>

The spinner that completes the question is added as an attachment

From the attached spinner, we have:

  • Total section = 12
  • Multiples of 3 = 4

The probability is then calculated as:

P(multiple of 3) = Multiples of 3/Total

This gives

P(multiple of 3) = 4/12

Evaluate

P(multiple of 3) = 0.3333

Hence, the value of the probability is 0.3333
