The value of x is to be randomly selected from the integers from 1 to 10, inclusive, and then substituted into the equation y = x2 – 4x + 3. what is the probability that the value of y will be negative?

======================================

Explanation:

Plug the values from this set {1,2,3,4,5,6,7,8,9,10} into the given equation y = x^2 - 4x + 3. You should get the table of values you see in the attached image below. Only one y value is negative, and that is y = -1 which happens when x = 2 (marked as point B). Otherwise, the y values are either 0 or positive. So we have 1 negative y value out of 10 y values total giving us the final answer 1/10.

answer: 40.95

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
