weeeeeb [17]

Answer:

The interval ( 1,8 ; 14,4 ) will contains 99,7 % of all values

Step-by-step explanation:

For Normal Distribution N ( μ ; σ ) the Empirical Rule establishes that in the intervals:

( μ ± σ ) we find 68,3 % of all values

( μ ± 2σ ) we find 95,4 % of all values

( μ ± 3σ ) we find 99,7 % of all values

Then we have a normal distribution N ( 8,1 ; 2,1 )

3*σ = 3* 2,1 = 6,3

And 8,1 - 6,3 = 1,8 8,1 + 6,3 = 14,4

Then the interval ( 1,8 ; 14,4 ) will contains 99,7 % of all values

What is the equation of a line that passes through the points (-3,4) and (2, 8

slavikrds [6]

Answer:

y = 4/5x + 32/5

Step-by-step explanation:

(-3,4) and (2, 8)

Slope:

m=(y2-y1)/(x2-x1)

m=(8-4)/(2+3)

m= 4/5

Slope-intercept:

y - y1 = m(x - x1)

y - 4 = 4/5(x + 3)

y - 4 = 4/5x + 12/5

y = 4/5x + 32/5
