0.4% of $4,800 is $19.2, otherwise written as $19.20 in terms of money, apparently. This is based off the calculations of a calculator, though if you prefer to do the rough work, be my guest. The work for finding it on raw work is below.

(EX.) EQUATION : y = p% × x
EQUATION : y = 0.4% × 4800

To make this work, you gotta convert that percent into a decimal, by dividing the percentage by 100. 0.4 ÷ 100 = 0.004

EQUATION : y = 0.004 × 4800.

Once you multiply them, you get : 19.2 (otherwise known as $19.20)

Answer:

The sample size will be " $102.5494 \sim 102$ ". A further explanation is given below.

Step-by-step explanation:

Let the sample size will be:

= n

The given values are:

Standard deviation,

= 1.4

ME,

= 0.3

As we know,

⇒ $n=(Z \frac{a}{2}\times \frac{SD}{E})^2$

On putting the estimated values, we get

⇒ $=(2.17\times \frac{1.4}{0 .3})^2$

⇒ $=(\frac{3.038}{0.3})^2$

⇒ $=102.5494 \sim 102$

John and Karen plan on building a garden in their new home. They plan on designing a rectangular garden with a perimeter of 70 f

valentinak56 [21]

Answer:

Length of the garden= 7 feet while the width =28 feet

Step-by-step explanation:

Let the length of the garden be L while the width represented as W

From the question, we deduce the following:

W = 4L

Perimeter = 2(L + W) = 70 feet .... substituting W = 4L into this equation gives

70 = 2(L + 4L)

70 = 2(5L)

70 = 10L ... dividing both sides by 10 gives

L = 7

Recall from the first equation that W = 4L

W = 4 * 7 =28
