Answer:
the mean is 54.428571428571<-------( what i think you are looking for )
the median is 51
the modes are 13, 19, 26, 27, 34, 45, 50, 52, 63, 76, 81, 86, 92, 98
Step-by-step explanation:
list all the numbers from greatest to least and the easiest way is to just cross them off left to right until you come up to one or two numbers. if one, that is your median. If two then add them up and divide them by two. We only had one, so the median is 51!
Hope this helped!
Answer:
117°
Step-by-step explanation:
Arc ABC (AB + BC) is intercepted by angle D.
Therefore, Arc ABC is 2 × m<D. (Inscribed Angle Theorem)
AB = 91°
m<D = 104°
Let BC = x
Arc ABC = (91° + x)
Thus,
91° + x = 2 × 104°
Solve for x
91 + x = 208
Subtract 91 from both sides
91 + x - 91 = 208 - 91
x = 117
Measure of arc BC = 117°
Answer:
Slope is 2, and the y-intercept is (0, 4).
Step-by-step explanation:
-2x+y=4
y=4-(-2x)
y=4+2x
y=2x+4
y=mx+b where m=slope and b=y-intercept,
m=2 and b=(0, 4).
Answer:
6.3 ×
Step-by-step explanation:
1 kilogram = 1000 grams
6300 kilograms = x grams
6300 × 1000 = x
x = 6,300,000 grams
Standard form = 6.3 ×
