Consider the probability distribution shown below. x 0 1 2 p(x) 0.15 0.60. 0.25 compute the expected value of the distribution.
Answer:
1.10
Step-by-step explanation:
Given the probability distribution :
x : ___ 0 ___ 1 ___ 2
p(x)__0.15 _0.60 __0.25
The expected value is obtained by:
Σ(X * p(x))
(0 * 0.15) + (1 * 0.60) + (2 * 0.25)
0 + 0.60 + 0.50
= 1.10

The delivery charge and daily rate to lease a construction crane are listed below for two companies.
High Top Cranes charges $744 for delivery and $3,290 per day.
Big Lift Equipment charges $1,428 for delivery and $3,214 per day.
If Builder's Construction Company leases a crane for 11 days, which leasing company has a lower total cost?
Answer: Big Lift Equipment
Step-by-step explanation:
From the question,
High Top Cranes charges $744 for delivery and $3,290 per day. Since Builder's Construction Company leases a crane for 11 days, the cost will be:
= $744 + $3290(11)
= $744 + $36190
= $36934
Big Lift Equipment charges $1,428 for delivery and $3,214 per day. Since Builder's Construction Company leases a crane for 11 days, the cost will be:
= $1428 + $3214(11)
= $1428 + $35354
= $36782
Based on the calculations, Big Lift Equipment has a lower cost

If all people were pea pickers, then how long would it take for the entire population of Earth to pick 1 mol of peas at the rate of one pea per second, working 15 hours per day, 365 days per year
It will take [tex] 1.392 \times {10}^{10} \: years[/tex] for the entire population of the Earth to pick a mole of pea at the specified rate.
1 mole of a substance is given by :
[tex]6.022 \times {10}^{23} [/tex]Rate per person = 1 pea per secondWorking 15 hours per day ; 365 days per year
1 person will pick = (1 × 365 × 15) = 5475 peas per year Taking the world population as 7,900,000,000 people Number of peas picked per year = (7,900,000,000 × 5475) = 43252500000000The time taken to pick 1 mole of pea will be :
1 mole of pea ÷ Number of peas picked per year [tex] \frac{6.022 \times {10}^{23} }{4.325 \times {10}^{13} } = 1.392 \times {10}^{10} \: years[/tex]The time taken to pick 1 mole of pea will be

What is the diagonal?
A polygon is defined as a flat or plane, two-dimensional closed shape bounded with straight sides.
A diagonal is a line segment connecting the opposite vertices (or corners) of a polygon. In other words, a diagonal is a line segment connecting two non-adjacent vertices of a polygon.
Here given that,
