Answer:
Mean = 36.67
Median = 36.5
Mode = 38
Step-by-step explanation:
Mean = [(35*8) + (37*7) + (37*4) + (38*9) + (39*2)] / (8+7+4+9+2)
Mean = (280 + 252 + 148 + 342 + 78) / 30
Mean = 1100 / 30 = 36.67
Median = Frequency of 35 and 36 is 15 total. Frequency of 37, 38, and 39 is the remainder 15 total. (36+37)/2 = 36.5
Mode = the most frequently-ocurring number = 38 (frequency of 9)
Answer:
12 cm
Step-by-step explanation:
The rule regarding secants and/or tangents is that the product of distances from their common point to the two intersection points with the circle is the same.
For the tangent the "two" intersection points with the circle are the same point, so ...
product of tangent lengths = product of secant lengths
(8 cm)(8 cm) = (4 cm)(4 cm +x)
Dividing by 4 cm gives ...
16 cm = 4 cm + x
12 cm = x
Answer:
this isn't the answer but is there a question?
Answer:
