Answer: B
Step-by-step explanation:
- If we add the numbers up, (47.6 + 7.32 + .0574 + 6) We get a answer of 60.9774.
Cot (x) = 3.2404
1/tan(x) = 3.2404
tan(x) = 1 / 3.2404
x = inverse tangent ( 1 / 3.2404 )
x = 72.8 degrees (3 s.f.)
Mean:
Add all the numbers:
13 + 17 + 15 + 18 + 21 + 13 + 20 + = 16.7
16.7 + 3.7 = 20.4
Mean = 20.4
Median:
Order the numbers:
13, 13, 15, 17, 18, 20, 21
The median, or middle number is 17.
17 + 3.7 = 20.7
Median = 20.7
Mode:
The number that repeats the most is 13.
13 + 3.7 = 16.7
Mode = 16.7
Range:
Highest Number = 21
Lowest Number = 13
21 - 13 = 8
Range = 8
The answer choice that matches is choice A.
Hope this helped☺☺
I’m so confused. Is there any other part to the question?
Y = 7x - 48
use slope formula so, y2 - y1 over x2 - x1 to get your m value or your slope which is 7. then plug in the slope and a random set of point so I used (6, -6). -6 = 6(7) + b, simplify.
-6 = 42 + b, subtract 42 which leaves you with b= -48. hope this helps :)
