Answer it pls and explain too

Answer:

y-intercept: (0, 5); slope: 1/4

Step-by-step explanation:

The slope (m) is found from ...

m = (y2 -y1)/(x2 -x1)

Using the first two points in the table, this is ...

m = (8 -6)/(12 -4) = 2/8 = 1/4 . . . . . eliminates choices A and C

Then, the point-slope form of the equation of the line can be written as ...

y -y1 = m(x -x1)

y -6 = (1/4)(x -4) . . . fill in known values

y = 1/4x -1 +6 . . . . . add 6

y = 1/4x +5

Then the value of y when x=0 is ...

y = 0 +5 = 5

So, the y-intercept is (0, 5) and the slope is 1/4, matching the last choice.

Answer:

a. 0.6899

b. 0.1642

Step-by-step explanation:

a. Given the probability of success is 0.94 for an expert and that the number of pairs, n=6:

-Each attempt is independent and therefore the probability of the events is calculated as:

$P(A \ and \B )=P(A)\times P(B)\\\\P(6)=0.94\times0.94\times0.94\times0.94\times0.94\times0.94\\\\=0.6899$

Hence, the probability of correctly identifying the 6 matches is 0.6899

b.Given the probability of success is 0.74 for a novice and that the number of pairs, n=6:

-Each attempt is independent and therefore the probability of the events is calculated as:

$P(A \ and \B )=P(A)\times P(B)\\\\P(6)=0.74\times0.74\times0.74\times0.74\times0.74\times0.74\\\\=0.1642$

#Hence, the probability of correctly identifying the 6 matches is 0.1642

*I have used the sample size of 6(due to conflicting info/question size).
