A coordinate plane with a line passing through the points (negative 4, negative 5) and (1, negative 1).
Ksju [112]

Answer:

4x - 5y - 9 = 0

\frac{9}{4}

\frac{-9}{5}

Step-by-step explanation:

The equation of a straight line passing through the points (-4,-5) and (1,-1) is given by \frac{y - (-5)}{-5-(-1)} =\frac{x-(-4)}{-4-1}

⇒ \frac{y+5}{-4} =\frac{x+4}{-5}

⇒ 5y + 25 = 4x + 16

⇒ 4x - 5y - 9 = 0 ....(1) (Answer)

Now, this above equation can be represented as

\frac{x}{\frac{9}{4} } + \frac{y}{\frac{-9}{5} } =1

Therefore, the x-intercept is \frac{9}{4} (Answer)

And the y-intercept is \frac{-9}{5}. (Answer)

suter [353]

Answer:

"Spin the spinner 5 times with 4 equal segments. One of the segment represents vanilla on either the spinner as well as three parts reflect certain flavors" would be the right answer.

Step-by-step explanation:

The actual probability of the given scenario will be:

⇒  (1-\frac{1}{4})^5

⇒  (1-0.25)^5

⇒  (0.75)^5

On solving the power, we get

⇒  (0.237304)

Now on multiplying the above value in 100, we get

⇒  23.73%

Approximately 23.73% chance vanilla was not chosen by either of the five. So that the above is the right answer.
