True, sound waves are created when vibrated and they travel through transverse waves
Answer:
19) 28°
20) 60°
21) 17°
Step-by-step explanation:
19)
Supplementary angles:
(x + 12)º + 140º = 180º
x + 12 + 140 = 180
x = 180 - 140 - 12
x = 28º
20)
Angles at a point:
(- 24 + x)° + 24° + 300° = 360°
- 24 + x + 24 + 300 = 360
x = 360 - 300
x = 60°
21)
Vertically opposite angles:
(1 + 3x)° = 52°
1 + 3x = 52
3x = 52 - 1
3x = 51
x = 17°
The deviation σ in the art book =15.4, the σ in the Science =7.9
Consequently the art book has data further away from the mean when compared to the science book. It will be difficult to have a valid inference.
No, because there is a lot of variability in the art book data
I believe the answer is 5:6
<em>The x and y intercept of 5x + 5y = -30 are (-6, 0) and (0, -6) respectively.</em>
<h2 /><h2>
Explanation:</h2>
The Standard Form of the equation of a line is given by:
So:
is written in Standard Form. The x and y intercepts are:
So:
FOR X-INTERCEPT:
FOR Y-INTERCEPT:
Finally,<em> the x and y intercept of 5x + 5y = -30 are (-6, 0) and (0, -6) respectively.</em>
