It’s Julio
If they’re asking for a break down on what happens Julio is def the answer
Let's write the general form of the sine curve:
, where,
- A is the amplitude. Also, if A is negative, curve reflects about x axis
- B is the compression/stretching factor. It changes the period when it is a value other than 1.
- C is the phase shift. It translates curve left or right. Negative value shifts right and positive value shifts left.
- D is the vertical shift. It translates curve up or down. Negative value shifts down and positive value shifts up.
Let's check the 4 choices.
A.
Since this curve's A is -2, its amplitude is 2 and range is from -2 to 2. BUT since D value is -3, it shifts vertically 3 units down making the range from -1 to -5. Clearly choice A is not true.
B.
This graph is the graph of shifted 3 units DOWN since D is negative. This choice isn't true.
C.
Because of the - (minus) sign in front of the function, the function is reflected about x-axis, but amplitude doesn't change. Since A value is 2, amplitude is 2. This is true.
D.
Period depends on the B value. Here, B value is 1, so period is normal as the parent function of a sine curve, which is , NOT . So this is not correct.
ANSWER: C is true
OK. So they sold 200 raffle tickets, and Jennie bought 5 of them.
What has to happen now in order for Jennie to win both prizes ?
-- First drawing. Jennie wins.
Probability = (5 tickets) / (200 possible draws) = 5/200
Now there are 199 tickets left in the barrel, and Jennie has 4 .
-- Second drawing. Jennie wins.
Probability = (4 tickets) / (199 possible draws) = 4/199 .
The probability of it happening just this way is
(5/200) x (4/199)
= (5 x 4) / (200 x 199)
= 20 / 39,800
= 2 / 3,980 = 1 / 1,990
= 0.0005025... = 0.05 % (rounded)
