Answer:

h = $\frac{25}{b+r}$

Step-by-step explanation:

Given

bh + hr = 25 ← factor out h from each term on the left side

h(b + r) = 25 ← divide both sides by (b + r)

h = $\frac{25}{b+r}$

densk [106]

a. The population for the study is a total of 1000 adults, so the 50% that favored the plan made up a total of 500 people, since 500 is 1/2 (or 50%) of 1000.

b. The percentage provided is an inferential statistic. Inferential statistics are made by taking a sample of a population and using that sample as data used to make inferences/predictions. Since the percentage provided is a sample of a population being used to make a prediction, it is an inferential statistic.

Given through: (2,4), and slope=4 how do you write the slope-intercept?

Anna11 [10]

Steps
1. Do the point slope form
Y-Y1=4(X-X1)
Y-4=4(x-2)
Y-4=4x + (-8)
2. Add 4 on both sides
Y= 4x-4
3. Your answer is
Y=4x-4

Complete the table shown to the right for the population growth model for a certain country.

marta [7]

The size of the population increases when the growth rate is positive and

decreases for a negative growth rate.

The completed table is presented as follows;

$\begin{array}{|c|c|c|}2003 \ Population (millions)&Projected \ 2029 \ Population \ (millions)&Growth \ rate \ K \\40.5&20.9&-2.255\%\end{array}\right]$

Reasons:

The table is presented as follows;

$\begin{array}{|c|c|c|}2003 \ Population (millions)&Projected \ 2029 \ Population \ (millions)&Growth \ rate \ K \\40.5&20.9&\end{array}\right]$

The population in growth rate is given by the following formula;

P = a·(1 + r)ˣ

Where;

a = The initial population in 2003 = 40.5 million

P = The population in 2029 = 20.9 million

x = The number of years = 2029 - 2003 = 26

Therefore;

20.9 = 40.5 × (1 + r)²⁹

$\left (1 + r\right)^{29} = \dfrac{20.9}{40.5}$

$r = \left(\dfrac{20.9}{40.5} \right)^{\dfrac{1}{29} } - 1 \approx -0.02255$

The population growth rate is r ≈ -0.02255 = -2.255 %

The completed table is therefore;

$\begin{array}{|c|c|c|}2003 \ Population (millions)&Projected \ 2029 \ Population \ (millions)&Growth \ rate \ K \\40.5&20.9&-2.255\%\end{array}\right]$
