Answer: -44.4°F
Step-by-step explanation:
17,750-8500=9,250
9250/1000=9.25
9.25x-4.8=-44.4
Answer:
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

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

Let 


Fraction of distance traveled on sunny weather

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
with respective probabilities
, then the Expectation or Expected value of X , denoted by E(X) = ∑pi xi

on simplification, we get
E(X) = 3.65
