At the beginning, there are 15 pigs without ribbons. one of the pigs receives a ribbon. how many are left ribbonless?
<span>14. when another pig is given a ribbon, there are 13 left. after all the ribbons have been given out, 3 of the 15 pigs have ribbons. </span>
<span>if any one of the 15 at the beginning is given a ribbon, there are 15 possible combos. for the second ribbon, there are 14 combos- but each of those combos has to go through the first 15. for the third ribbon, there are 13 combos, going through 14 and 15. </span>
<span>simply put, 15 x 14 x 13.</span>
since the area of the rectangle is 13 square inches and the length is 3.25 inches subtract 3.25 from 13

which makes your width 9.75
to find the perimeter you add
9.75 + 3.25 + 9.75 + 3.25= 26.5
The perimeter of the rectangle is 26.5
Answer:
Step-by-step explanation:
Let X be the IQ
IQ is normally distributed with a mean of 100 and a standard deviation of 15.
a) the probability that this person has an IQ greater than 95
=
=62.93%
b) the probability that this person has an IQ less than 125

=4.75%
c) Sample size =500

No of people = 0.2486(500) =124.3
d) 
No of persons = 0.0047(500) = 2.35
Answer:
y=3-2x
Step-by-step explanation:
Parallel to y = 3 − 2 x => y=c-2x
Through (3,1) => 1=c-2(1) <=> c=3
Line is y=3-2x
