Lynna [10]

Answer:

Step-by-step explanation:

A margin of error provides information on the percentage points ones results will differ from the real value.

If margin of error is 3% and estimated value is 6%, it means that the confidence interval would be within ±3 of the estimated value.

So, the confidence interval would be between 3% (6% - 3%) and 9% (6% + 3%)

timama [110]

Answer:

Pattern $x$ : $0,6,12,18$

Pattern $y$ : $1,2,4,8$

Step-by-step explanation:

Given:

Pattern x: start with 0 and add 6.

Pattern y: start with 1 and multiply 2.

To find: patterns $x$ and $y$

Solution:

Pattern $x$ : $0,0+6,0+6+6,0+6+6+6=0,6,12,18$

Pattern $y$ : $=1,1(2),1(2)(2),1(2)(2)(2)=1,2,4,8$

An open-top box with a square base is to have a volume of 4 cubic feet. Find the dimensions of the box (in ft) that can be made

Lemur [1.5K]

Answer:

The dimension of box= $2ft\times 2ft\times 1ft$

Step-by-step explanation:

We are given that

Volume of box=4 cubic feet

Let x be the side of square base and h be the height of box

Volume of box= $lbh=x^2h$

$4=x^2h$

$h=\frac{4}{x^2}$

Now, surface area of box,A= $x^2+4xh$

$A=x^2+4x(\frac{4}{x^2})=x^2+\frac{16}{x}$

$\frac{dA}{dx}=2x-\frac{16}{x^2}$

$\frac{dA}{dx}=0$

$2x-\frac{16}{x^2}=0$

$2x=\frac{16}{x^2}$

$x^3=8$

$x=2$

$\frac{d^2A}{dx^2}=2+\frac{32}{x^3}$

Substitute x=2

$\frac{d^2A}{dx^2}=2+\frac{32}{2^3}=2+4=6>0$

Hence, the area of box is minimum at x=2

Therefore, side of square base,x=2 ft

Height of box,h= $\frac{4}{2^2}=1 ft$

Hence, the dimension of box= $2ft\times 2ft\times 1ft$
