Answer:
2√10
Step-by-step explanation:
Given the coordinates (-6, 2) and (0,0)
We are to find the distance between the coordinates. Using the distance formula;
d = √(x2-x1)²+(y2-y1)²
d = √(0-2)²+(0+6)²
d = √(-2)²+(6)²
d = √4+36
d = √40
d = √4*10
d = 2√10
Hence the required distance is 2√10
69.9 is exactly 3 standard deviations away, which means that 78.9 is +3 (more than 3) standard deviations
So the answer is 78.9
Answer:
Step-by-step explanation:
x^2/100 + y^2/25=1 -----(1)
Since 25<100
Hence the above equation is of the form x^2/a^2+ y^2/b^2=1-------(2)
Comparing (1) and (2)
a^2=100
a=10
Major axis=2a=20
2/5 x 26 = 52/5
6 2/3 x 4 1/5 = 8/3 x 21/5 = 8 x 7/5 = 56/5
