Write statements to declare and initialize two variables: one, named element_number can hold any of the integer values 1 through

118; the other, named atomic_weight can hold the atomic weight of the given element; atomic weights are values like 3.76. in the declaration, initialize the variables to the values for oxygen, which is element number 8 and has an atomic weight of 15.9994.

In this problem, we are asked to declare statements that describe the orders given as stated. In the first command, we are to define the element number of the element specified, which by, in this case, is oxygen. This is expressed: Element number  = 8. Then we name the element that is element = oxygen. The third command specifies the atomic weight of the elementoxygen = 15.9994. For the last command, the expression is atomic weight = oxygen. It is important to arrange the commands in order so that the program that understands the data executes the orders well and translate them into output.

) Thirty percent of the students in a management class are graduate students. A random sample of 3 students is selected. a) Usin
adell [148]

Given Information:  

Probability of success = 30%

Sample size = n = 3

Variable of interest = x = 2  

Required Information:  

Probability of exactly 2 graduates = ?

Answer:

Probability of exactly 2 graduates = P(2; 3, 0.30) = 0.189

Step-by-step explanation:

The given problem can be modeled as a binomial experiment since a random selected student can either b graduate or not therefore, there are only 2 outcomes. Each trial is independent and the probability of success is not changing from trial to trial. The number of trials in also fixed.

We know that a binomial distribution is given by

P(x; n, p) = nCx pˣ (1 - p)ⁿ⁻ˣ

Where p is the probability of success and 1 - p is the probability of failure, n is number of independent trials and x is the variable of interest.

For the given problem, we know that x = 2, n = 3 and p = 0.30

P(2; 3, 0.30) = 3C2*0.30²*(1 - 0.30)³⁻²

P(2; 3, 0.30) = 3*0.30²*(0.70)¹

P(2; 3, 0.30) = 0.189

Part A: The sun produces 3.9 ⋅ 1033 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in 3
jolli1 [7]

Answer:

Step-by-step explanation:

Given that :

Radiant energy produced per second = 3.9 * 10^33 ergs

Amount of radiant energy produced in (t) = 3.25 * 10^3 s

Radiant energy per second * time

(3.9 * 10^33) * (3.25 * 10^3)

12.675 * 10^(33 + 3)

12.675 * 10^36 ergs

= 1.2675 * 10^37 ergs

Reasonable distance for measuring tracks on a railroad:

1.435 ⋅ 10−3 mm or 1.435 ⋅ 103 mm?

1.435 × 10^-3 mm = 0.001435 mm

1.435 × 10^3 mm = 1435mm

1.435 × 10^3 mm seems more reasonable
