We can calculate (62 + 90) / 2 = 76. it's <span>known that 95% lies between the mean and twice the standard deviation. </span><span>if the mean is "μ" and the standard deviation is "σ": </span><span>μ-2σ and μ+2σ. i</span><span>f μ=76, then </span><span>76+2σ = 90, so 2σ = 14, so σ = 7.

<span>the mean is 76 and the standard deviation 7. </span>
Answer:
(2,8)
Step-by-step explanation:
The midpoint of a line segment with endpoints (a,b) and (c,d) is
((a+c)/2 , (b+d)/2) .
So one endpoint is given and the midpoint is given, we are asked to find the other midpoint.
(10+c)/2=6 (4+d)/2=6
10+c=12 4+d=12
c=2 d=8
(2,8) is the other endpoint
Step-by-step explanation:
height = constant / width
that means
constant = height × width.
so, we only need to multiply the 2 coordinate numbers of one of the points.
the easiest is clearly (0.8, 1).
0.8 × 1 = 0.8
so, the constant is 0.8
Answer:
The greatest common factor of these two numbers is 3
Step-by-step explanation:
To find this, look for the highest number that both can be divide by to get whole numbers.
39/3 = 13
6/3 = 2
