The probability that a point is chosen at random in the square is in the blue region is 0.8.

<h3>What is Probability?</h3>

The probability helps us to know the chances of an event occurring.

\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}

As we know that the area of the shaded region is the sum of the area of triangle A and the area of triangle B. Therefore, the area of the blue shaded region is,

\text{Area of shaded region} = (\dfrac{1}{2} \times 8 \times 8) + (\dfrac{1}{2} \times 4 \times 8)

                                  = (32) + (16)\\\\= 48\rm\ in^2

The area of the square can be written as,

\text{Area of Square} = \rm(Side)^2 = 8^2 = 64\ in^2

Now, the probability that a point is chosen at random in the square is in the blue region can be written as,

\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\

\rm Probability = \dfrac{\text{Area of blue region}}{\text{Area of square}}\\\\Probability = \dfrac{48}{60} = 0.8

Hence, the probability that a point is chosen at random in the square is in the blue region is 0.8.

Q2
RideAnS [48]

Answer:

264 miles

Step-by-step explanation:

Let's convert 3 hours and 40 minutes into hours first.

Recall that 1 hour = 60 minutes.

Therefore 40 minutes = 40/60 hours = 2/3 hours.

The car travelled 3 and 2/3 hours in total.

Recall that distance = speed times time.

The car has travelled 72 x 3 2/3 miles = 264 miles.

lesantik [10]
14.6 is the constant because no matter how many hours she will work (that number could change) it will always be a linear growth of 14.6.
