m1=3, m2= 1
point A= (-5,4)
point B=(7,-2)
x=m1x2+m2x1/ m1+m2 , y=m1y2+m2y1 / m1+m2
x= 3×7 +1×-5/3+1 , y= 3×-2+1×4 / 3+1
x= 21-5/4, y= -6+4/4
x= 16/4, y= -2/4
x= 4, y= 0.5
X=7
Vertical angles measure the same
Let the first number be = x
Let the second number which is consecutive be = x+1
As given, the product of two consecutive square numbers is 144
Square rooting both sides we get
or 
Neglect the negative value so we get x=3
Hence, one number is 3 and the consecutive number is = 3+1=4
The square of the numbers are 9 and 16.
Answer:
Look at my in the photo
Step-by-step explanation:
The mean : 2.5 million
S D = 0.6 million
2.5 - 2 · 0.6 = 2.5 - 1.2 = 1.3 million
2.5 + 2 · 0.6 = 2.5 + 1.2 = 3.7 million
Chebyshev theorem : at least 3/4 of the data lie within 2 standard deviations of the mean.
