Mathematics

Answer:

Hello, from my calculations, this equation does not have a solution.

Step-by-step explanation:

-2(3x-1) = (-6x) - 1

-6x + 2 = -6x - 1

*+6x from the left side and +1 from the right side*

0=3

0=3 is incorrect and invalid. Plus, in the process of solving for x, the x variable was eliminated.

2x + 3x + 3x + 12 = 180° [Sum of all angles of a triangle is 180°]

=> 7 x = 180° - 12°

=> 7 x = 168°

=> x = $\frac{168}{7}$ °

=> x = 24°

$\\$

? = 2x + 3x

=> 2×24° + 3×24°

=> 48° + 72°

The normal monthly temperatures (°F) for Omaha, Nebraska, are recorded below.

Answer

$y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49$

Step by Step Explanation

Given

See attachment for table

Required

Determine the sinusoidal function

The sinusoidal function is represented as:

$y = A \sin(Bx + C) + D$

Where

$|A| = Amplitude$

And it is calculated as:

$A = \frac{1}{2}[Highest - Least]$

From the table:

Highest = 77 and Least = 21

So:

$A = \frac{1}{2}[77 - 21]$

$A = \frac{1}{2}[56]$

$A = 28$

B is calculated as:

$Period = \frac{2\pi}{B}$

The period is 12 i.e. 12 months

So:

$\frac{2\pi}{B} = 12$

$B = \frac{2\pi}{12}$

$B = \frac{\pi}{6}$

C is calculated as:

$\frac{C}{B} = -4$

$C = -4 * B$

$C = -4 * \frac{\pi}{6}$

$C = -2 * \frac{\pi}{3}$

$C = -\frac{2\pi}{3}$

Lastly, D is calculated as:

$D = Least + A$

So:

$D =21 + 28$

$D=49$

So, the function is:

$y = A \sin(Bx + C) + D$

$y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49$

A drawer contains nine white paper clips five green paper clips and six red paper clips one paper clip is selected at random wha

alexandr1967 [171]

Judging on the question I realized to find the probability of finding a white paperclip would be a fraction.
The numerator of the fraction should be (9) white paperclips. The denominator of the fraction should be (20) the TOTAL amount of paperclips (white+green+red).
The fraction should be 9/20. or 45%
