Answer:
Probability[(X - μ) < 1.1] = 0.6046
Step-by-step explanation:
Given:
σ² = 64
Mean μ = 34
Find:
Probability[(X - μ) < 1.1]
Computation:
Standard deviation σ = √σ²
Standard deviation σ = √64
Standard deviation σ = 8
Probability[(X - μ) < 1.1] = Probability[-1.1 < (X - μ) < 1.1]
Probability[(X - μ) < 1.1] = Probability[-1.1/(8/√38) < (X - μ) < 1.1/(8/√38)]
Using z table
Probability[(X - μ) < 1.1] = 0.6046
Point Form:
(1,3) (5,-9)
Equation Form:
x=1 y=3
x=5 y=-9
solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
x=2
Step-by-step explanation:
- add like terms (3x-9x= -6x, 7-3= 4)
- then move the constant to the right (-8+4=-12)
- finally divide it by 6 which gives you "x"
40/50= 0.8
293/1000=0.293
Step-by-step explanation:
40/50
= 0.8
293/1000
Since the zeros are three,move three times from backwards to forward.
=0.293.
