timama [110]2 years ago
3 0

Answer:

1.581

Step-by-step explanation:

Given the data:

13 15 14 16 12

The point estimate of the standard deviation will be :

√Σ(x - mean)²/n-1

Mean = Σx / n = 70 / 5 = 14

√[(13 - 14)² + (15 - 14)² + (14 - 14)² + (16 - 14)² + (12 - 14)² / (5 - 1)]

The point estimate of standard deviation is :

1.581

Solve the literal equation for the indicated variable. P= 2(l+w) for w
Lorico [155]

Answer:

P=2(l+w)

divide the both sides by 2

make w the subject of the formula

P/2 - l =w

w = P/2 - l

Alik [6]

Answer:

Option D.) 236 degrees

Step-by-step explanation:

Angle GFE is half of the central angle. Measure of central angle is congruent to it's intersecting arc, therefore;

<em>2 * ∠GFE = Arc GE (?)</em>

2 * 118 = Arc GE (?)

<u>236 = Arc GE (?)</u>

Hope this helps!

Factor completely 81x8 − 1. (9x4 − 1)(9x4 1) (3x2 − 1)(3x2 1)(9x4 − 1) (3x2 − 1)(3x2 1)(9x4 1) (3x2 − 1)(3x2 1)(3x2 1)(3x2 1).
mojhsa [17]

Answer:

(3x^2 - 1)(3x^2 + 1)(9x^4 + 1).

Step-by-step explanation:

Using the identity for the difference of 2 squares;

a^2 - b^2 = (a - b)(a + b)  

we put a^2 = 81x^8 and b^2 = 1  giving

a = 9x^4 and b = 1, so:

81x^8 − 1 =   (9x^4 - 1)(9x^4 + 1)

Applying the difference of 2 squares to 9x^4 - 1:

= (3x^2 - 1)(3x^2 + 1)(9x^4 + 1).
