CB = DA = √3*3+1*1 = √10
CD = BA = √2*2+1*1 = √5
Sum is 2√10 + 2√5 ≈ 10.8. So answer A.
Answer:
The quantitative variables in this case are:
A. Speed
D. GForce
E. Height
G. Duration
H. Numinversions
J. Length
Step-by-step explanation:
One criteria to differentiate qualitative variables from quantitative variables is to determine if mathematical calculations over these variables makes sense.
If it makes sense, it is a quantitative variable.
For example, binary variables, although they can be represented by 0 and 1, would be a qualitative variable.
The quantitative variables in this case are:
A. Speed
D. GForce
E. Height
G. Duration
H. Numinversions
J. Length
They all will be represented by numbers for which mathematical operations make sense.
1) add.
for example -1 + -2 = - (||-1| + |-2||), which is -(1+2) or -3
2) subtract
for example 4 + -7 = -(||-7| + |4||), which is - |7 - 4| or -3
3) change
for example 3 - (- 2) = 3 + 2
4) -10
the sum is -10.25, which is closest to -10
For given Poisson distribution, <span>μ=8.
</span>P(x)=μ^x*e^(-<span>μ)/x!
so
P(4)=1.5^4*e^(-1.5)/4!= 0.04707 approx.</span>
