a number cubes tolled 450 times. the number 3 comes up 67 times. what I's the theoretical probability of rolling a 3 ? WRITE YOU
zvonat [6]
Assuming number cube has 6 sides

probablity is (desiredoutcomes)/(total possible ouctomes)


since it is 450 times
total possible outcomes=450

experimiental probablity is the one actaully obtained by doing it
theoretical is the predicted amount

so theoretical probablity of rolling a 3 is 1 number out of 6 or 1/6 or 75 times out o 450 times

experimiental is the actaull one so67 out of 450 or 67/450

theoretical is 1/6 or 75/450
experimental is 67/450

The population of Linton is 12 times as great as the population of Elmore the combined population of both towns is 9,646 people
zysi [14]
Let the population of Elmore be "X".
Since that the population of Linton is 12 times as great as the population of Elmore, then it is considered to be "12x".
Since that the sum of both Elmore and Linton is 9.646, then "X + 12x = 9464" x+12x is 13x , so it should be "13x = 9464". Now, it is easy to find the population of Elmore which is 9464 / 13 = 742. Since that the population of Linton is 12 times the population of Elmore, then the population of Linton is "742 * 12 = 8904".

every day, kojo write 3 pages

number of days he has written his story= d days

from the final sentence,

3d= 81

<h3>(a) the equation to describe the situation: </h3><h3>3d= 81</h3>

(b) number of days kojo has been writing his story

3d= 81

dividing through by d

3d/3= 81/3

d = 27

<h3>therefore number of days = 27</h3>
