Answer:

Step-by-step explanation:

The area of a square is length*width.

We can square root the area to get the length of each side. Since the shape is a <em>square</em>, the lengths are the same.

$\sqrt{64}$ =8

One side is <u>8m</u>.

Answer:

The standard deviations is $\frac{-5}{3}$

Step-by-step explanation:"

Given mean female height = 64 inches and standard devaiton = 3 inches and 69 inches tall is Sally.

We know the distance of a data point from:

Z = $\frac{64-69}{3}$ = $\frac{-5}{3}$

So the standard deviations is $\frac{-5}{3}$

The cost c, for manufacturing x flags is given by c=x? -24x +39. Find the number of flags manufactured if the cost is $120.

IRINA_888 [86]

9514 1404 393

Answer:

Step-by-step explanation:

You want to find x when c = 120.

120 = x^2 -24x +39

x^2 -24x -81 = 0 . . . . . . subtract 120 to put in standard form

(x -27)(x +3) = 0 . . . . . .factor it

Solutions are ...

x = 27, x = -3 . . . . . values of x that make the factors zero

The number of flags manufactured for a cost of $120 is 27 flags.
