Option c 71 3/4

Step-by-step explanation:

Step 1 :

The area of a rectangle is length * breadth

Step 2 :

Given length = 15 3/8 = 123/8 (converting mixed fractions into improper fractions)

Breadth = 4 2/3 = 14/3

Step 3 :

Hence the area of the rectangle = length * breadth

= 123/8 * 14/3 = 1722/24 = 71 3/4 (converting improper fractions into mixed fractions)

If point P is at the center of the circle, and the length of AB equals 12 inches, which is the length of AP?

Natasha2012 [34]

Answer:

B. 6 inches

Step-by-step explanation:

We know that the lenght of AB is 12 inches. Given that any two point that passes through the center P equals to the diameter, we know that AP is going to be half of diameter.

So, if AB = 12, then P = AB/2 = 6 inches.

The bucket containing orange tennis balls and yellow tennis balls from which 5 balls are selected at random, but assume that the

NeX [460]

(1)

Probability that all are yellow = $\frac{7\times6\times5\times4\times3}{16\times15\times14\times13\times12}=0.0048$

Probability that all are orange = $\frac{9\times8\times7\times6\times5}{16\times15\times14\times13\times12}=0.0288$

Sum of the two probabilities = 0048+ 0.0288=0.0336

Thus, the probability that at least one is orange and at least one is yellow = 1-0.0336= 0.9664= 96.64 %

(2) In addition to the above, we eliminate the "1 and 4" cases.

In these cases, any of the 5 can be taken out, so we multiply by 5.

1 yellow + 4 orange = $5\times \frac{(7 \times 9 \times 8 \times 7 \times 6)}{(16 \times 15 \times 14 \times 13 \times12)} = 0.2019$

1 orange + 4 yellow = $5 \times \frac{(9 \times 7\times 6 \times 5 \times 4)}{(16 \times 15\times 14 \times 13 \times 12)} = 0.0721$

Sum of two probabilities = 0.2019+0.0721=0.2740

Now adding 0.0336 to this probability =0.0336+0.2740= 0.3076

Subtracting that from 1.0000 = 1-0.3076=0.6924= 69.24 %

Thus, the probability that, of the 5 balls selected at random, at least two are orange and at least two are yellow= 69.24%
