Answer 1

The correct ordering of the graphs from least value of n to greatest value of n is A, B, C.

The three graphs, A, B, and C, represent the results of three simulations of a sampling distribution of a sample mean. Graph A has a value of n of 200, Graph B has a value of n of 200 and Graph C has a value of n of 0. Thus, the correct ordering of the graphs from least value of n to greatest value of n is A, B, C. To understand this, it is important to note that as the value of n increases, the sample means will be more representative of the population. Therefore, Graph A with the lowest value of n would have the least representative sample means, followed by Graph B and Graph C with the highest value of n having the most representative sample means.

g neptunium-239 has a half-life of 2.35 days. how many days must elapse for a sample of 239np to decay to 0.100% of its original quantity? 0.0427 days 1.491 days 2.04 days 23.4 days

Answers

23.5 days must elapse for a sample of 239np to decay to 0.100% of its original quantity.

Given is the equation for radioactive decay.

N equals N0exp(-λt). We have to determine the λ decay constant.

λ= -(lnN/N0)/t where t = Neptunium-239's half-life, 2.35 days,

and N/N0 = 1/2 where N = Amount of Neptunium-239 after half-life,

and N0 = Amount of Neptunium-239 at the beginning.

Consequently,

λ = (-ln(1/2))/2.35 = 0.294/day.

Neptunium-239 will now degrade to 0.100% of its original value.

N/N₀ × 100 % = 0.100%

N/N₀ = 0.100/100

N/N₀ = 0.001

We calculate the time it takes for Neptunium-239 to decay to this value using the equation for radioactive decay. Making t the formula's subject,

-(lnN/N0)/ = -(ln(0.001))/0.294/day.= 23.5 days

How do you find how many times greater something is in scientific notation

Answers

Answer: The number it is a power too

To determine how many times greater something is in scientific notation, you need to compare the exponents of the numbers and calculate the ratio between them.

In scientific notation, a number is expressed as the product of a coefficient (a decimal number between 1 and 10) and a power of 10. The exponent represents the number of places the decimal point has been moved.

To find how many times greater one number is than another, you compare the exponents of the powers of 10. If the exponent of the first number is n and the exponent of the second number is ᵃ, you can calculate the ratio by dividing 10ⁿ by 10ᵃ.

The result of this division will give you the factor by which the first number is greater than the second number. For example, if the result is 100, it means the first number is 100 times greater than the second number.

In summary, to determine how many times greater something is in scientific notation, compare the exponents of the powers of 10 and calculate the ratio between them.

What is linear equation in math?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
