kozerog [31]

Reduce the fraction 6/12 to its lowest expression by extracting and canceling 6.

$\bf{ \dfrac{1}{2}+\dfrac{2}{3}+\dfrac{1}{6} }$

Convert 1/2 and 2/3 to fractions with denominator 6.

$\bf{\dfrac{1\times3}{2\times3}+\dfrac{2\times2}{3\times2}+\dfrac{1}{6} \ \ \to \ \ \ Multiply }$

$\bf{ \dfrac{3}{6}+\dfrac{4}{6}+\dfrac{1}{6} }$

Since 3/6, 4/6, and 1/6 have the same denominator, add their numerators to add them together.

$\bf{\dfrac{3+4+1}{6} \ \ \to \ \ \ Add }$

Add 3 plus 4 plus 1.

$\bf{\dfrac{8}{6} }$

Reduce the fraction 6/8 to its lowest expression by extracting and canceling 2.

$\bf{\dfrac{4}{3} \ \ \to \ \ \ Answer }$

The population mean annual salary for environmental compliance specialists is about $63 comma 500. A random sample of 31 specia

Nat2105 [25]

Answer:

0.0035289

Step-by-step explanation:

From the question;

mean annual salary = $63,500

n = sample size = 31

Standard deviation = $6,200

Firstly, we calculate the z-score of $60,500

Mathematically;

z-score = x-mean/SD/√n = (60500-63500)/6200/√(31) = -2.6941

So we want to find the probability that P(z < -2.6941)

We can get this from the standard normal table

P( z < -2.6941) = 0.0035289

Meldie made a cube whose side is (3x - 2) inches. Find its volume in cubic inches.

irinina [24]

Answer:

x^2(3x-2) cubic inches OR in^3

3x { 3 [ 3x ( x - 2 ) + 4 ] } - 8 cubic inches OR in^3

I AM UNAWARE IF YOU ASKED THAT ONE SIDE IS (3X-2) OR ALL. I WILL ANSWER BOTH PARTS

-

NOTE: '^' MEANS TO THE POWER OF..

-

Volume = v, abc = 3 sides of cube (height, width, length)

Using the formula for volume in a cube,

$v = abc$

We can solve this.

If one side is (3x-2)in,

(3x-2)(x)(x) = v.... x are the other two sides
x^2(3x-2) = v

x^2(3x-2) cubic inches OR in^3

If all sides are (3x-2)in,

Use the formula,

$(a - b) ^{3} = {a}^{3} + 3ab(b - a) - {b}^{3}$

We can solve this.

(3x-2)(3x-2)(3x-2) = v
(3x-2)^3 = v.... 3x = a and -2 = b
(3x)^3 + [(3)(3x)(2)][2-3x] - (2)^3 = v
27x^3 + 18x(2-3x) -8 = v
(27x^3 + 36x - 54x^2) - 8 = v.. Terms inside brackets - take 3x as common and leave out 8
3x(9x^2 -18x +12) = v... Take 3 as common again in the brackets
3x [ 3 ([3x^2 -6x] + 4) -8 = v....Take 3x common in the terms in square brackets
3x [ 3 [ 3x (x-2) + 4 ]] - 8 = v
3x { 3 [ 3x ( x - 2 ) + 4 ] } - 8 = v

3x { 3 [ 3x ( x - 2 ) + 4 ] } - 8 cubic inches OR in^3

5(x-19) In distributive property

AlexFokin [52]

So you would get 5(x) and 5(-19)

So 5x and -95

So 5x-95
