Life sciences: weight. the average weight of a baby born in 1900 was 6 pounds 4 ounces. in 2000 the average weight of a newborn was 6 pounds 10 ounces. what is the rate of change of birth weight in ounces per year? what do we expect babies to weigh at birth in 2040

The expected weight of babies in 2040 is 136.4 ounces.

Step-by-step explanation:

Since we have given that

Average weight of a baby born in 1900 = 6 pounds 4 ounces =

Average weight of a baby born in 2000 = 6 pounds 10 ounces =

So, the rate of change of birth weight in ounces per year would be

Since slope = 0.06

Let x be the year and y be the weight in ounces.

So, the equation of line would be

Now, put x = 2040

So, it would become

Hence, the expected weight of babies in 2040 is 136.4 ounces.

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
