Answer:
Step-by-step explanation:
1. cannot be determined. We don't have all the numbers so you can't find the mean (average).
2. True. The median is the line in the middle of the box. The median for movie 1 is greater than 600 and the median for movie 2 is less than 600.
3. True. Interquartile range is the biggest number of the box minus the smallest number of the box. Movie 1 is approximately 200 and movie 2 is approximately 70.
4. True. Q3 is the last line of the box.
Answer:
The answer would be 6.7b + 2
Step-by-step explanation:
In order to simplify this, simply add the like terms together.
3.8b + 2.9b = 6.7b
-7 + 9 = 2
Now just put those two together
6.7b + 2
Answer:
x = 4
Step-by-step explanation:
all angles in triangle add to 180
90+70=160
180-160=20
20÷5=4
F1 . . . 100% of it = 900N is in the +x direction.
F2 . . . 70.7% of it (cos45°, 530.3N) is in the +x direction,
and 70.7% of it (sin45°, 530.3N) is in the +y direction.
F3 . . . 80% of it (520N) is in the -x direction,
and 60% of it (390N) is in the +y direction.
Total x-component: 900 + 530.3 - 520 = 1,950.3 N
Total y-component: 530.3 + 390 = 920.3 N
Magnitude of the resultant = √ (x² + y²)
= √(1950.3² + 920.3²)
= √4,650,070.09
= 2,156.4 N .
Angle of the resultant, measured counterclockwise
from the +x axis, is
tan⁻¹ (y / x)
= tan⁻¹ (920.3 / 1950.3)
= tan⁻¹ (0.4719)
= about 25.3° .
