Mathematics

marta [7]3 years ago

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]

Answer:

0.375, Terminating

Step-by-step explanation:

Mackenzie has 32 books and 12 of which are by her favorite author.

One of the easier ways to convert something to a decimal is to first start as a fraction. We need to have it be the number of books by her favorite author (12) out of the total number of books that she owns (32)

This in the form of a fraction would be \frac{12}{32}

Now, let us reduce this fraction.

Both terms can be divided by 4

\frac{12}{32}/\frac{4}{4} \\\\\frac{3}{8}

Recall that \frac{1}{8} =0.125

This means that

\frac{3}{8} =3*0.125=0.375

As you can see. this decimal stops after 3 places, which means that it is terminating.

nevsk [136]

Answer:

Cost of pencil is $0.35 and cost of pen is 0.75

Step-by-step explanation:

The cost of one pencil and one pen is required.

The cost of a pencil is $0.35 and a pen is $0.75.

The number of pens is 12.

The number of pencils is 20.

Let the cost of one pencil be  

A pen costs $0.40 dollar more than pen.

So, cost of a pen is  

Total cost of all the pens and pencils is $16.

Cost of pencil is $0.35 and cost of pen is 0.75

A Rasmussen Reports survey of 1,000 US adults found that 42% believe raising the minimum wage will help the economy. Construct a
vitfil [10]

Answer:

(0.3798, 0.4602)

Step-by-step explanation:

Let p be the true proportion of US adults who believe raising the minimum wage will help the economy. A point estimate for p is \hat{p}=0.42 and a good aproximation (because we have a large sample) for the standard deviation of \hat{p} is \sqrt{\hat{p}(1-\hat{p})/n}=\sqrt{0.42(0.58)/1000}=0.0156. Therefore, a 99% confidence interval for p is given by \hat{p}\pm z_{\alpha/2}\sqrt{\frac{\hat{p}(1-\hat{p})}{n}} where \alpha=0.01 and z_{\alpha/2} is the \alpha/2th quantile of the standard normal distribution, so we have, 0.42\pm z_{0.005}0.0156, i.e., 0.42\pm(-2.5758)(0.0156) or equivalently (0.3798, 0.4602).
