On a partly cloudy day, Derek decides to walk back from work. When it is sunny, he walks at a speed of s miles/hr (s is an integ
Setler [38]

Answer:\frac{1}{7}

Step-by-step explanation:

Given

sunny day speed= s mph

Rainy day speed=s+1 mph

Derek average speed =2.8 miles/hr

s<2.8<s+1

so on sunny day speed must be 2 mph

and on rainy day speed must be 3 mph

v_{avg}=\frac{distance}{time\ taken}

Let x be the distance traveled in sunny and y be the distance traveled in rainy weather

2.8=\frac{x+y}{\frac}{x}{2}+\frac{y}{3}}

Let \frac{x}{y}=z

2.8=\frac{z+1}{\frac{z}{2}+\frac{1}{3}}

z=\frac{1}{6}

Fraction of distance traveled on sunny weather

\frac{x}{x+y}=\frac{z}{z+1}=\frac{1}{7}

An online instructor sends updates to students via text. The probability model describes the number of text messages the instruc
alexandr402 [8]

Answer:

The expectation the instructor to send each day

E(X) = 3.65

Step-by-step explanation:

Given data   x   :    0      1           2        3         4        5

P(X=x)               :   0.05 0.05    0.1    0.1         0.4     0.3

The given data satisfy the two conditions

I) Given all probabilities are p₁(x) ≥0

ii) sum of all probabilities is equal to one

0.05 + 0.05 + 0.1  +  0.1 + 0.4 +0.3 =1

Therefore given data is discrete probability distribution

<u>Expectation</u> :-

suppose a random variable X assumes the values x_{1}, x_{2},..x_{n} with respective probabilities p_{1}, p_{2},..p_{n} , then the Expectation or Expected value of X  , denoted by E(X) = ∑pi xi

E(X) = 0X0.05+1X 0.05 +2X 0.1  +3X 0.1 +4X0.4 +5X 0.3

on simplification, we get

E(X) = 3.65
