Answer:

3- False,
4- True

Step-by-step explanation:

<h3>Garden A</h3>

<u>Rectangle with sides</u>

Width ⇒ 2x - 3 feet
Length ⇒ 5(2x - 3) = 10x - 15

<u>Perimeter is</u>

2(w + l) = 2( 2x - 3 + 10x - 15) = 24x - 36

<h3>Garden B</h3>

<u>Triangle with sides</u>

5x + 5, 4x + 2, 8x - 8

<u>Perimeter is</u>

5x + 5 + 4x + 2 + 8x - 8 = 17x - 1

<h3>Statement 3</h3>

<u>The difference in perimeters is the difference is fencing:</u>

24x - 36 - (17x - 1) = 24x - 17x - 36 + 1 = 7x - 35

Since it is different from 7x - 37 the statement is FALSE

<h3>Statement 4</h3>

Garden A is surrounded by a path of 2.5 ft wide

It will have the perimeter added by 2.5*2*4 = 20 ft as each side is extended by 2*2.5 ft = 5ft

<u>So the perimeter is going to be:</u>

24x - 36 + 20 =
24x - 16

This statement is TRUE

part of the population of 4,500 elk at a wildlife preserve is infected with a parasite a random sample of 50 elk shows that 8 of

REY [17]

Answer:

A total of 720 elk are likely to be infected

Step-by-step explanation:

we shall be using the proportion by survey to estimate the number of infections

From the survey 8 out of 50 are infected. Thus the likelihood of infection is 8/50

We have 4,500 elk to consider. The number of elk likely to be infected will be 8/50 * 4500 = 720

namely, how many times does 3/4 go into 3½? Let's firstly convert the mixed fraction to improper fraction.

$\bf \stackrel{mixed}{3\frac{1}{2}}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{7}{2}\div \cfrac{3}{4}\implies \cfrac{7}{~~\begin{matrix} 2 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}\cdot \cfrac{\stackrel{2}{~~\begin{matrix} 4 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}}{3}\implies \cfrac{14}{3}\implies 4\frac{2}{3}$
