Answer:
Hours of television because it is the explanatory variable.
Step-by-step explanation:
For me, I am assuming the more time spent watching television would cause lower reading scores. I imagine this would be a bar graph, the vertical y-axis would be labeled the reading scores and the horizontal x-axis would be the amount of hours spent watching television. This is because when you graph, you move right then up to get to the unit, meaning the hours of television affect the reading scores. hope this helpss
Answer:
180
Step-by-step explanation:
Answer:
Correct answer: second quadrant angle is 3π/4
fourth answer (2√2 + π) / 4
third quadrant angle is 5π/4
first answer (-2√2 + π) / 4
Step-by-step explanation:
Your question does not define the quadrant in which the angle is of the
cos⁻¹ (- √2/2).
If it is in the second quadrant then the angle is 3π/4 and if it is in the third quadrant then the angle is 5π/4
1) second quadrant angle is 3π/4
sin ( cos⁻¹ (- √2/2)) + tan⁻¹ ( sin ( π/2)) = sin ( 3π/4) + tan⁻¹ 1 =
= √2/2 + π/4 = (2√2 + π) / 4
2) third quadrant angle is 5π/4
sin ( cos⁻¹ (- √2/2)) + tan⁻¹ ( sin ( π/2)) = sin ( 5π/4) + tan⁻¹ 1 =
= - √2/2 + π/4 = (-2√2 + π) / 4
