t hits the square dartboard shown below at a random point. Find the probability that the dart lands in the shaded circular regio
masha68 [24]

Given:

Required:

To find the probability that the dart land will be in the shaded region.

Explanation:

Area of the circle is given by the formula:

A=\pi r^2

Where r = radius

Thus the area of the circular region

\begin{gathered} =(3.14)\times(2)^2 \\ =3.14\times4 \\ =12.56\text{ square in.} \end{gathered}

The area of the square is given by the formula:

=(side)^2

Thus the area of the given square

\begin{gathered} =(6)^2 \\ =36\text{ square in.} \end{gathered}

The probability of an event is given by the formula:

P=\frac{number\text{ of possible outcomes}}{Total\text{ number of outcomes}}

The probability that the dart land will be in the shaded region

=\frac{Area\text{ of the shaded region}}{Area\text{ of the square}}

Thus probability

\begin{gathered} P=\frac{12.56}{36} \\ P=0.3488 \\ P=0.349 \end{gathered}

Final answer:

Thus the probability that the dart land will be in the shaded region is 0.349.

2 1/5 /10 = x/4, using proportions, solve for x, and explain.
lisov135 [29]

Answer:

x = 22/25

Step-by-step explanation:

Given

2 1/5            x

---------- = -----------

10              4

Using cross products

2 1/5 * 4 = x*10

Change 2 1/5 to an improper fraction

2 1/5 =(5*2+1)/5 = 11/5

11/5 *4 = 10x

44/5 =10x

Multiply each side by 1/10 to isolate x

44/5 *1/10 = 10x * 1/10

44/50 = x

Divide top and bottom by 2

22/25 = x
