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.

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables
