Answer:

The probability that the next color will be red is: \dfrac{2}{3}

Step-by-step explanation:

The probability of an event is defined as:

Probability=(Total number of favourable outcomes)/(Total number of outcomes )

Here we have to find the probability that the next colour is red is given by:

<em>The recordings are given as:</em>

B  R  Y  R  R  R  R  Y  R  B  R  R

Number of outcomes that red will come up=8

Total number of outcomes=12

Hence the probability is given by:

Probability=\dfrac{8}{12}=\dfrac{2}{3}

A spotlight is mounted on the eaves of a house 30 feet above the ground. A flower bed runs between the house and the​ sidewalk,
never [62]

Answer:

The ladder should be 34 feet long.

Step-by-step explanation:

The height of the spotlight above ground = 30 feet

The base of the ladder will be = 16 feet from the base of house

We can easily assume this to be a right triangle with perpendicular as 30 feet and base as 16 feet and we have to find the hypotenuse.

Lets say the length of the ladder or hypotenuse is = x

We will apply Pythagoras theorem here.

30^{2} +16^{2} =x^{2}

=> 900+256 =x^{2}

=> 1156 =x^{2}

=> x=\sqrt{1156}

So, x = 34

Hence, the ladder should be 34 feet long.
