Answer:

Sheila is 0.61 meters taller than her son.

Step-by-step explanation:

First, you would convert 109 cm into meters. Once converted, Sheila's son would be 1.09. Then you would subtract 1.09 from 1.7 to find your answer!

you work for a telecommunications company and need to analyze the outcome of a proposed new cell tower project. cell phone radio
umka21 [38]

Answer:

The equations describing the area which each tower covers are given as

Tower A : x^{2} + y^{2} = 16

Tower B : (x - 5)^{2} + (y - 4)^{2} = 9

Tower C : (x - 4)^{2} + (y + 4)^{2} = 25

Step-by-step solution:

Cell phone radio towers broadcast a cell phone signal in circular pattern

Tower A at Adele Acres have position co-ordinates  as (0,0) and a coverage radius of  4 ml. So, the area which it covers is given by the equation,

x^{2} + y^{2} = 16 -------------------------------(1)

Tower B at Brown Lake have position co-ordinates  as (5,4) and a coverage radius of  3 ml. So, the area which it covers is given by the equation,

(x - 5)^{2} + (y - 4)^{2} = 9 -------------------------------(2)

Tower C at Cady City have position co-ordinates  as (4,-4) and a coverage radius of  5 ml. So, the area which it covers is given by the equation,

(x - 4)^{2} + (y + 4)^{2} = 25 -------------------------------(2)

Suppose that the p-value was 0.0259. what is the appropriate conclusion to make if α = 0.05?
fiasKO [112]
<span>It is clear to see that 0.0259 is less than 0.05. A p-value that is less than the confidence level of alpha indicates that there is sufficient evidence from the data that the null hypothesis should be rejected in favor of an alternative hypothesis.</span>

Thetime(inhours)requiredtorepairamachineis an exponentially distributed random variable with parameter λ = 1 . What is 2 (a) the
mihalych1998 [28]

Answer:

a) 0.1353

b) 0.3679

Step-by-step explanation:

Let's start by defining the random variable T.

T : ''The time (in hours) required to repair a machine''

T ~ exp (λ)

T ~ exp (1)

The probability density function for the exponential distribution is

(In the equation I replaced λ = L)

f(x)=Le^{-Lx}

With L > 0 and x ≥ 0

In this exercise λ = 1 ⇒

f(x)=e^{-x}

For a)

P(T>2)

P(T>2)=1-P(T\leq 2)

P(T>2)=1-\int\limits^2_0 {e^{-x} } \, dx

P(T>2)=1-(-e^{-2}+1)

P(T>2)=e^{-2}=0.1353

For b)

P(T\geq 10/T>9)

The event (T ≥ 10 / T > 9) is equivalent to the event T ≥ 1 so they have the same probability of occur

P(T\geq 10/T>9)=P(T\geq 1)

P(T\geq 1)=1-P(T

P(T\geq 1)=1-(-e^{-1}+1)=e^{-1}=0.3679
