Answer:

<em>The range of the data set would be 12.</em>

Step-by-step explanation:

We need to arrange all the numbers in the data set from least to greatest.

21, 24, 26, 27, 29, 33

Range: Highest value - Lowest value = final answer

21, 24, 26, 27, 29, 33

Range: 33 - 21 = 12

Which of the following best describes the solution to the system of equations below?

liraira [26]

For this case we have the following system of equations:

$6x + 3y = 6\\6x + 3y = 14$

We multiply the first equation by -1:

$-6x-3y = -6$

We have the following equivalent system:

$-6x-3y = -6\\6x + 3y = 14$

We add the equations:

$-6x + 6x-3y + 3y = -6 + 14\\0 = 8$

Equality is not fulfilled, so the system of equations has no solution.

If sec theta = - √30 / 3, find cos theta.<br> if sin(-theta) = -0.97, find cos (π/2 - theta).

Cloud [144]

Step-by-step explanation:

$\cos \theta = \frac{1}{ \sec\theta } = - \frac{3}{ \sqrt{30} } = - \frac{3 \sqrt{30} }{30} = - \frac{ \sqrt{30} }{10}$

$\cos( \frac{\pi}{2} - \theta )= \cos \frac{\pi}{2} \cos \theta + \sin \frac{\pi}{2} \sin \theta$

Note that

$\sin( - \theta) = - \sin \theta$

$\cos \frac{\pi}{2} = 0 \: \: \: \: \: \sin \frac{\pi}{2} = 1$

Therefore,

$\cos( \frac{\pi}{2} - \theta ) = 0.97$
