ella [17]

Answer: Linear model H(t)=9t+100 and H'(t) = 9 units.

Step-by-step explanation:

Since we have given that

In 2000, amount spent = $100 billions

In 2010, amount spent = $190 billions.

So, rate of increase would be

\dfrac{190-100}{2010-2000}\\\\=\dfrac{90}{10}\\\\=9

So, linear model for H(t) would be

H(t)-190=9(t-10)\\\\H(t)=9t-90+190\\\\H(t)=9t+100

So, H'(t) would be 9.

Hence, linear model H(t)=9t+100 and H'(t) = 9 units.

A biology class conducts a bird count every week during the semester. Using the number of species counted each​ week, a student
luda_lava [24]

Answer:

A student finds a​ 95% confidence interval of​ (16.34,18.69) for the mean number of species counted. This is a valid interval because the mean number of species or any population mean does not necessarily have to be a whole number, as stated by the student.

This given confidence interval of (16.34,18.69) helps us to simply estimate the mean species counted.
