Top right because 3 is the y intercept and it goes down by 2 for every 1 x

The amount of time, in minutes, that a woman must wait for a cab is uniformly distributed between zero and 12 minutes, inclusive
murzikaleks [220]

Answer:

P(X\leq x) =\frac{x-a}{b-a}, a \leq x \leq b

And using this formula we have this:

P(X

Then we can conclude that the probability that that a person waits fewer than 11 minutes is approximately 0.917

Step-by-step explanation:

Let X the random variable of interest that a woman must wait for a cab"the amount of time in minutes " and we know that the distribution for this random variable is given by:

X \sim Unif (a=0, b =12)

And we want to find the following probability:

P(X

And for this case we can use the cumulative distribution function given by:

P(X\leq x) =\frac{x-a}{b-a}, a \leq x \leq b

And using this formula we have this:

P(X

Then we can conclude that the probability that that a person waits fewer than 11 minutes is approximately 0.917

The expression -16t ^2+ 48t can be written as the product of -16t with which of the following?
Gelneren [198K]

Answer:

4) t -3

Step-by-step explanation:

-16t² = -16 * t * t

48t = (-16t) * (-3)

-16t² + 48t = (-16t) * t + (-16t) *(-3)

                = (-16t) [ t - 3]

Rotation 90 degrees counterclockwise about the origin​
nataly862011 [7]

Answer:

  • Point W = (-3, 3)
  • Point X = (-3, 2)
  • Point V = (-2, 3)

<em>The rotation rule states that rotation 90° counterclockwise means (x, y) = (-y, x)</em>

<u>The new points would be equal to:</u>

  • Point W' = (-3, -3)
  • Point X' = (-2, -3)
  • Point V' = (-3, -2)

Try graphing it to see if the new points make sense<em>(because I'm not too sure :\)</em>

At 3:20 the hands of a clock form an acute angle that measures exactly how many degrees
Goryan [66]

Answer:

The answer is 30°.

Step-by-step explanation:

The hand of a clock rotates a full 360°, let's say 12 o'clock is 0°/360°. The hour hand for this example is at 3, it moved 90° and the minute hand marks 20 minutes meaning it's positioned on the 2. From 12 to 2 the minute hand has moved 60°. 90-60= 30. Therefore 3:20 forms a 30° angle.
