astraxan [27]2 years ago
4 0

Answer:

0.02 (the first option)

Step-by-step explanation:

This is because a proportion means there is division going on. If 5 out of the 250 students have red hair, this creates a fraction of \frac{5}{250} and when you divide this out: 5 ÷ 250, you get 0.02

A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the
IrinaVladis [17]

Answer:

Step-by-step explanation:

A) 16.13 = 12(1.03)ⁿ

   1.344 = (1.03)ⁿ

ln(1.344) = n(ln(1.03))

           n = (ln(1.344)) / ln(1.03)

           n = 10.0062...

so a domain of 0 ≤ n ≤ 10 is reasonable

B) y-intercept is the height of the plant on day 0 which would be 12 cm

C) f(3) = 12(1.03)³ = 13.11 cm

average rate of change = Δh/Δn = (16.13 - 13.11) / (10 - 3) = 3.02 / 7

= 0.43 cm/day  or average growth per day

When you Divide a whole number by a fraction with a numerator of one explain how you can find the quotient
kumpel [21]
Well for example: 10/1 divided by 1/2
What you will do you would flip 1/2 it would now become 2/1
Then you change the sign to multiplication so your equation will look like 10/1*2/1 then just multiply from there on out.
