Question isn't well formatted ;

If the question meant that choosing a marble for five hundred times ; then the calculation is stated below:

Answer:

214

Step-by-step explanation:

Given that :

Probability of picking a red out of a bag of colored marble = 3 : 7 ; that is 3 / 7

P(red) = 3 / 7

If the number of picks (with replacement) = 500

Then, the approximate number of red marbles chosen will be :

P(red) * number of picks

3/7 * 500 = 214.285

Approximate Number of red marbles chosen = 214

dem82 [27]

Answer:

The other dimension of the pasture (width) is 1.625\ mi

Step-by-step explanation:

In this problem I assume that the pasture has the shape of a rectangle.

Let

x -----> the length of the pasture

y -----> the width of the pasture

we know that

The area of the pasture (rectangle) is equal to

A=xy

we have

A=0.65\ mi^{2}

x=0.4\ mi

substitute and solve for y

0.65=0.4y

y=0.65/0.4

y=1.625\ mi

Answer:

Step-by-step explanation:

5/6 of an estate is to be divided among relatives

Remaining estate = 1 - 5/6

= 6-5/6

= 1/6 of the estate

Of the remaining a state 1/3 goes to the American cancer society

what fraction of the estate goes to the American Cancer Society

= 1/3 × 1/6

= 1/18

The fraction of the estate that goes to the American Cancer Society = 1/18
