PiR^2 is the area so R^2 = 4*4 = 16
16 * Pi = 50.265 the rug will take up 50.265 ft

What is the next term of the following sequence? <br><br><br> 20, 10, 5, 21/2, ...

ycow [4]

Answer:

1 $\frac{1}{4}$

Step-by-step explanation:

Note there is a common ratio between consecutive terms, that is

10 ÷ 20 = 5 ÷ 10 = 2 $\frac{1}{2}$ ÷ 5 = $\frac{1}{2}$

Thus to obtain the next term in the sequence multiply the previous term by $\frac{1}{2}$

2 $\frac{1}{2}$ × $\frac{1}{2}$ = 1 $\frac{1}{4}$

Suppose we are interested in bidding on a piece of land and we know one other bidder is interested. The seller announced that th

Alik [6]

Answer:

$P(X$

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 your bid will be accepted would be 0.41

Step-by-step explanation:

Let X the random variable of interest "the bid offered" and we know that the distribution for this random variable is given by:

$X \sim Unif( a= 10100, b =14700)$

If your offer is accepted is because your bid is higher than the others. 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 your bid will be accepted would be 0.41

A playing field is rectangular with a length of 100 yards and a width of 53 yards, 1 foot. If a player runs diagonally across t

musickatia [10]

First convert yards to feet.

1 yard = 3 feet.

100 x 3 = 300 feet long.

53 x 3 = 159 + 1 = 160 feet wide.

Now use the Pythagorean theorem to find the diagonal.

x^2 = 300^3 + 160^2

x^2 = 90000 + 25600

x^2 = 115600

x = √115600

x = 340 feet
