You look over the songs in a jukebox and determine that you like 1414 of the 5252 songs. (a) What is the probability that you l

enyata [817]

Answer:

Step-by-step explanation:

given that you look over the songs in a jukebox and determine that you like 14 of the 52 songs

Here each song is independent of the other song

i.e. p = Probability that you like any song = $\frac{14}{52} =0.2692$

q = Prob you do not like = 1-0.2692 = 0.7308

a) the probability that you like the next four songs that are played

= $0.2692^4\\=0.00525$

b) the probability that you do not like the next four songs that are played

= $0.7308^4\\=0.2852$

Find the coordinates of the three points on the graph of y = (1/2)x² -2x whose x-values are −2, 0, and 4.

MaRussiya [10]

Answer:

y = 6

y = 0

Step-by-step explanation:

$y=\frac{1}{2}x² -2x$

When, x = -2

$y=\frac{1}{2}\times (-2)^2-2\times(-2)\\\Rightarrow y=\frac{1}{2}4+4\\\Rightarrow y=2+4\\\Rightarrow y=6$

y = 6

When, x = 0

$y=\frac{1}{2}\times (0)^2-2\times(0)\\\Rightarrow y=0+0\\\Rightarrow y=0$

y = 0

When, x = 4

$y=\frac{1}{2}\times (4)^2-2\times(4)\\\Rightarrow y=\frac{1}{2}16-8\\\Rightarrow y=8-8\\\Rightarrow y=0$

y = 0
