Answer:

The statement makes conclusions about the proportion of citizens of the United States of America with respect to a particular opinion. These conclusions or inferences are obtained from the statistical analysis of a sample of said citizens, assuming a probabilistic distribution for the variable of interest (proportion). This type of analysis is part of the interval estimation theme that is part of the statistical inference or mathematical statistics.

Solve the equation.5/6=1/3+d
TiliK225 [7]
Solving a linear equation

We have the following equation

\begin{gathered} \frac{5}{6}=\frac{1}{3}+d \\  \end{gathered}

We substract 1/3 each side:

\begin{gathered} -\frac{1}{3}+\frac{5}{6}=-\frac{1}{3}+\frac{1}{3}+d \\ -\frac{1}{3}+\frac{5}{6}=0+d \\ -\frac{1}{3}+\frac{5}{6}=d \\  \end{gathered}

We multiply each side of the fraction 1/3 by 2:

-\frac{1}{3}=-\frac{1\cdot2}{3\cdot2}=-\frac{2}{6}

Then

\begin{gathered} -\frac{1}{3}+\frac{5}{6}=d \\ -\frac{2}{6}+\frac{5}{6}=d \\ \frac{3}{6}=\frac{1}{2}=d \end{gathered}<h2>Answer: d = 1/2</h2>

How do you find the midpoint of a trapezoid ?
FrozenT [24]
A trapezoid midsegment connects the midpoints of the two congruent sides of the trapezoid, and is parallel to the pair of parallel sides. The length of the midsegment is the sum of the two bases divided by 2. Remember that the bases of a trapezoid are the two parallel sides.

A rectangle swimming pool is 8 feet deep. One side of the pool is 4.5 times longer than the other. The amount of water needed fo
wel

The side lengths of the pool 10 ft and 45 ft.

<u>SOLUTION: </u>

Given, a rectangle swimming pool is 8 feet deep.  

One side of the pool is 4.5 times longer than the other.  

Let the length of pool be n feet, the width will be 4.5n feet

The amount of water needed for the swimming pool is 3600 cubic ft

We have to find the dimensions of the pool. Now, we know that,  

\begin{array}{l}{\text {volume of pool}=\text {depth} \times \text {length } \times \text {width}} \\\\ {\rightarrow 3600 \text { cubic } f t=8 \text { feet } \times \text { n feet } \times(4.5 n) \text { feet }} \\\\ {\rightarrow 8 n \times 4.5 n=3600} \\\\ {\rightarrow 36 n^{2}=3600} \\\\ {\rightarrow n^{2}=100}\end{array}

On taking square root on both sides we get,

\begin{array}{l}{\rightarrow\sqrt{n^{2}}=\sqrt{100}} \\\\ {\rightarrow n=10 \mathrm{ft}}\end{array}

So, the width will be 4.5 n=4.5 \times 10=45 \mathrm{ft}
