To be a function, for any X value( input) you can only have one Y(output value).

In A) there are two x values of 2, but each one has a different Y value, so this cannot be a function.

In C, there are two x values of 1, each with a different Y value, so also cannot be a function.

D) has two X values of 0, and each has a different Y value so cannot be a function.

The correct answer would be B.

How to write y-6=-5/2 (x+4)
coldgirl [10]

Answer:

In point slope form, this is y = (-5/2)x + 2.  In standard form, it's (5/2)x + y = 2.

Step-by-step explanation:

y-6=-5/2 (x+4) has already been written in point-slope form.  The slope of the line is -5/2 and the point on the line is (-4,6).

In slope-intercept form:  add 6 to both sides of the original equation, obtaining y = 6 - (5/2)(x + 4), or y = 2 - (5/2)x, or y = (-5/2)x + 2

Approximately 40% of the calls to an airline reservation phone line result in a reservation being made. (round to three decimal
IRISSAK [1]

Answer:

The probability that none of the 10 calls result in a reservation is 0.60%.  In turn, the probability that at least one call results in a reservation being made is 99.40%.

Step-by-step explanation:

Since approximately 40% of the calls to an airline reservation phone line result in a reservation being made, supposing an operator handles 10 calls, to determine what is the probability that none of the 10 calls result in a reservation, and what is the probability that at least one call results in a reservation being made, the following calculations must be performed:

0.6 ^ 10 = X

0.006 = X

0.006 x 100 = 0.60%

Therefore, the probability that none of the 10 calls result in a reservation is 0.60%.

100 - 0.60 = 99.40

In turn, the probability that at least one call results in a reservation being made is 99.40%.
