QUESTION 1 0.3
Last year in Bernardsville, there were 4,581 births. In reviewing their birth certificates, researchers found that
672 had low birthweights (<2,500 grams), and 1,580 had mothers who smoked during pregnancy. Of the
mothers who smoked during pregnancy, 290 had low birth weight babies.
Set up the two by two table for these data.

QUESTION 2
0.375 po

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
