Megan has a large packing box shaped as a cube with a volume of 216 cubic feet.
Flura [38]

Answer:

s = 6 feet

Step-by-step explanation:

Given that,

The volume of the cube, V = 216 feet³

We need to find the side length for the cubical box. We know that the volume of the cube is given by :

V=s^3, s is the side length of the box.

So,

s={V}^{1/3}\\\\s={216}^{1/3}\\\\s=6\ feet

So, the side length for the cubical box is equal to 6 feet.

Find the two Z-scores that separate the middle 73.72% on the Standard Normal Curve.
leonid [27]

Answer:

+1.12 and -1.12

Step-by-step explanation:

Let the two z scores be -z_1and+z_1.

Since  the two Z-scores that separate the middle 73.72% on the Standard Normal Curve, this can be represented by the equation:

P(-z_1

From the z table of the normal distribution, z₁ = 1.12. That is a z score of 1.12 gives 0.8686.

The two z scores are +1.12 and -1.12 = ± 1.12

Brainliest and 20 points!!!!
denis23 [38]

Answer:

A

Step-by-step explanation:

The n th term ( explicit formula) for a geometric sequence is

f(n) = a(r)^{n-1}

where a is the first term and r the common ratio

Here a = 2 and r = - 8 ÷ 2 = - 4, thus

f(n) = 2(-4)^{n-1}
