Let X denote the number of bars of service on your cell phone whenever you are at an intersection with the following probabiliti
ZanzabumX [31]

Answer:

a. P(2 \leq X \leq 3) = 0.5

b. P(X \geq 1) = 0.9

c. P(X < 2) = 0.25

d. P(X > 3) = 0.25

Step-by-step explanation:

We are given the following distribution:

P(X = 0) = 0.1

P(X = 1) = 0.15

P(X = 2) = 0.25

P(X = 3) = 0.25

P(X = 4) = 0.15

P(X = 5) = 0.1

a. Two or three bars

P(2 \leq X \leq 3) = P(X = 2) + P(X = 3) = 0.25 + 0.25 = 0.5

Thus:

P(2 \leq X \leq 3) = 0.5

b. At least one bar

P(X \geq 1) = 1 - P(X = 0) = 1 - 0.1 = 0.9

Thus:

P(X \geq 1) = 0.9

c. Fewer than two bars

P(X < 2) = P(X = 0) + P(X = 1) = 0.1 + 0.15 = 0.25

Thus:

P(X < 2) = 0.25

d. More than three bars

P(X > 3) = P(X = 4) + P(X = 5) = 0.15 + 0.1 = 0.25

Thus:

P(X > 3) = 0.25

A cube is built with inside dimensions of 10 inches. The material is 0.2 inches thick. Use a Taylor series approximation to find
larisa86 [58]

Answer:

V(x,y,z) ≈ 61.2 in

Step-by-step explanation:

for the function f

f(X)=x³

then the volume will be

V(x,y,z)= f(X+h) -  f(X) , where h= 0.2 (thickness)

doing a Taylor series approximation to f(x+h) from f(x)

f(X+h) - f(X) = ∑fⁿ(X)*(X-h)ⁿ/n!

that can be approximated through the first term and second

f(X+h) - f(X) ≈ f'(x)*(-h)+f''(x)*(-h)²/2 = 3*x²*(-h)+6*x*(-h)²/2

since x=L=10 in (cube)

f(X+h) - f(X) ≈ 3*x²*(-h)+6*x*(-h)²/2 = 3*L²*h+6*L*h²/2 = 3*L*h*(h+L)

then

f(X+h) - f(X) ≈  3*L*h*(h+L) = 3* 10 in * 0.2 in * ( 0.2 in + 10 in ) = 61.2 in

then

V(x,y,z) ≈   61.2 in

V real = (10.2 in)³-(10 in)³ = 61 in
