Answer: 16) (17)
(18)
(19) 3x - 18
<u>Step-by-step explanation:</u>
Inverse is when you swap the x's and y's and then solve for y
16) Given: y = x²
Swapped: x = y²
17) Given: y = 2x + 4
Swapped: x = 2y + 4
x - 4 = 2y
18) Given: y = (x + 2)²
Swapped: x = (y + 2)²
√x = y + 2
19) Given:
Swapped:
3(x - 6) = y
3x - 18 = y
Answer:
Here, 16 % of the total population of a large country is hopelessly romantic.
.
Assuming events are independent,
Probability of a person who is hopelessly romantic = 16% = 16/100
(a) Probability of both will be hopelessly
romantic =
= 0.0256...ans
Probability that are not hopelessly
romantic = 100% - 16%= 84%
= 0.7056
(b) So, the probability of atleast one is hopelessly romantic = 1 - 0.7056
= 0.2944...ans
.
Hope it helps!
