Answered Leven purple marbles, seven orange marbles and two pink marbles are in a bag. What is the probability of selecting a purple marble, not replacing it, and then selecting an orange marble?
Question 4 options:

19%

20%

21%

22%

20% (pls mark me brainliest)

Step-by-step explanation:

1. you have to figure out what percentage each marble is by dividing 100 by the total amount of marbles 100 ÷ 16 = 6.25%

2. you then take that sum and you multiply it times seven because there are seven purple marbles, 6.25 x 7 = 43.75% which is the probability that you'll pick a purple marble.

3. you would then have 15 marbles so you would have to do step 1. again but with 15 substituted instead of 16, 100 ÷ 15 = 6.67%

4. after that you would do step 2. again, this time taking 6.67 and multiplying it by seven because of the seven orange marbles: 6.67 x 7 = 46.69%

5. since for this to work you would need to choose the purple one in the first place you need to figure out what 46.69% is out of 43.75%: 20.426875% which rounds down to 20%

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
