7 0

Answer:

0.028

Step-by-step explanation:

The equation for opposite probabilities is 1 - P(A)

This means 1 minus the probability of event A which in this question is the event of the washing machine working properly.

So to find the chance that it will not work properly:

1 - 0.972 =0.028

I hope this helped!

What are the slope and the y-intercept of the linear function that is represented by the table?

natka813 [3]

Slope is 2/5 and the y into is -1/3

I just went with the slope. So I am not sure about the y-int.

Slope= y2 -y1 over x2-x1

(-2/15–1/30) =-.1
—————————- (over)
(-1/2- -3/4) =. -.75

- 0.1 / - 0.25 = .4 = 2/5
