Answer: y = (x +2)² + 5
<u>Step-by-step explanation:</u>
y = a(x - h)² + k <em>where "a" is the leading coefficient and (h, k) is the vertex</em>
Since we don't know "a", we need to plug in the point (x, y) and the vertex (h, k) to solve for "a": (x, y) = (0, 9) and (h, k) = (-2, 5)
y = a(x - h)² + k
9 = a(0 - (-2))² + 5
9 = a(0 + 2)² + 5
9 = a(2)² + 5
<u>-5 </u> <u> -5 </u>
4 = a(4)
<u>÷4 </u> <u> ÷4 </u>
1 = a
Next, plug in "a" and the vertex (h, k):
y = a(x - h)² + k
y = 1(x +2)² + 5
y = (x +2)² + 5
Answer:
90%
Step-by-step explanation:
Probability of households with one TV = 35% or 0.35
Probability of households with two sets = 39% or 0.39
Probability of households with three or more = 16% or 0.16
The probability of a household with no TV set = 0.10 or 10% (1 - 0.35 - 0.39 - 0.16)
Therefore, the probability of a household with at least one or more sets = 90% (35% + 39% + 16%) or 100% - 10%.
Probability is the chance that something may occur out of many events. To calculate probability, we divide the number of events by the number of possible outcomes.
