Reptile [31]

Answer:

3x - y = -5

<u>-3x -3x</u>

<u>-y</u> = <u>-3x</u> <u>-5</u>

-1 -1 -1

y = 3x + 5

Step-by-step explanation:

  1. subtract 3x from both sides. 3x cancel 3x, but it can't cancel -5 since it doesn't have any x.
  2. since y is negative, divide both sides by -1.
  3. the slope here is 3x, but the slope intercept form is y = 3x + 5

Find P(C|Y) from the information in the table. A 5-column table has 4 rows. The first column has entries A, B, C, Total. The sec
Monica [59]

The probability is the ratio of the favorable event to the total number of events. The P(C|Y) is 0.5. Then the correct option is B.

<h3>What is probability?</h3>

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

According to the problem, the table is made

                          X               Y               Z               Total

  A                    32              10             28                 70

  B                     6                5              25                 36

  C                    18               15              7                   40

Total                 56              30             60                146

Then the probability of will be

\rm P(C|Y) = \dfrac{15}{30}\\\\P(C|Y) = 0.5

The P(C|Y) is 0.5. Then the correct option is B.
