Step-by-step explanation:
If we convert
to a Cartesian equation,
So we have a circle with center (-5,0), with a diameter of 10.
Answer:
5
Step-by-step explanation:
b is at 15
n is at 10
hence -15 - -10=5
positive 5 btw
Answer:
B
Step-by-step explanation:
Each histogram section represents all values from the left value, to the right value of each section (i.e the section after 10 represents all values from 10 to 20).
If we break all the weights into categories by this principle, with frequencies in parenthesis, we get;
0-10: (0)
10-20: (0)
20-30: 21, 24 (2)
30-40: (0)
40-50: 42, 47 (2)
50-60: 54, 56 (2)
60-70: 65 (1)
70-80: 72 (1)
80-90: 83, 86 (2)
90-100: (0)
with these numbers, we know for certain that the correct answer is B
The answer is of the figure is 24
