Tritium is a radioactive isotope of hydrogen that decays by about 5% per year. A large bottle of water that contained 450,000 tritium atoms remained undisturbed for 11 years. How much tritium does the bottle contain now?
If necessary, round your answer to the nearest whole number
Using an exponential function, it is found that the bottle contains 255,960 atoms of tritium after 11 years.
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem:
The bottle initially contained 450,000 tritium atoms, hence A(0) = 450000.The amount decays by about 5% per year, hence r = 0.05.Thus, the equation is given by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]A(t) = 450000(1 - 0.05)^t[/tex]
[tex]A(t) = 450000(0.95)^t[/tex]
After 11 years, the amount is given by:
[tex]A(11) = 450000(0.95)^{11} = 255960[/tex]
The bottle contains 255,960 atoms of tritium after 11 years.

Rafael has a bag of marbles, there are 5 green marbles, 6 red marbles, and 4
5
white marbles. Rafael picks a marble out of the bag without looking. What is the
probability of P(red n white)?
The probability of getting red marble from the consider withdrawal of a marble is 0.107 approximately.
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
Given that:
The bag contains:
5 green marbles,6 red marbles,45 white marbles.Rafael draws one marble at randomSince he draws one marbel, thus, only one colored marble would come out.
Let we suppose we've to find P(red marble coming out).
Then, if we take:
E = event of Rafael drawing a red marble,
then E can be done in 6 ways as there are 6 red marbles to choose from.
Also, withdrawal of 1 marble (of any color) can be done in (5+6+45 = 56) 56 ways.
Thus, we get:
[tex]P(E) = P(\text{Choosing a red marble}) = \dfrac{6}{56} = \dfrac{3}{28} \approx 0.107[/tex]
Thus, the probability of getting red marble from the consider withdrawal of a marble is 0.107 approximately.

Which of the following equations is not a linear equation?
(LOOK AT PHOTO!!!)
Answer:
I think that B is not a linear equation.
Step-by-step explanation:
Linear eqautions can not contain exponents in them. B has x to the power of 3 and y to the power of 2, ruling it out to be a linear equation.
I hope this helps! :)
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
Linear equation has a degree of 1, that means the maximum power of a variable in a linear equation/expression should be 1. if an equation doesn't satisfy this condition then it's not a linear equation.
So, by Observing the choices, we get to the conclusion that the one which isn't a linear equation is B
[tex]\qquad \sf \dashrightarrow \: {x}^{3} - 5 {y}^{2} = 4[/tex]
Here, the variables have greater powers tham one, and degree is 3. so it's the required Answer ~

The bonds of the products store 27 kJ more energy than the bonds of the reactants. How is energy conserved during this reaction?
A. The reaction system absorbs 27 kJ of energy from the surroundings.
B. The reaction creates 27 kJ of energy when bonds form.
C. The surroundings absorb 27 kJ of energy from the reaction system.
D. The reaction uses up 27 kJ of energy when bonds break.
As per the law of conservation of energy:
C. The reaction system absorbs 22 kJ of energy from the surroundings
Law of conservation of energy:This law of energy states that the energy remains conserved its neither created nor destroyed. It remains conserved throughout the reaction.
when an amount of heat gets absorbed during the reaction from the surroundings this type of reaction is known as an endothermic reaction.
So, for fulfilling law of conservation, same amount of energy must be asborbed.
Thus, option C is correct.

Answer:
56 degrees
Step-by-step explanation:
The total amount of degrees in a triangle is 180: all three angles add up to 180. We can set up an equation to solve this.
40 + 2x + 3x = 180
Let's add like terms:
40 + 5x = 180
Subtract 40 on both sides:
5x = 140
Divide by 5 on both sides to solve for x:
x = 28
Angle A is equal to 2x. Plug in 28 for x. 2*28 = 56. Therefore, Angle A is 56 degrees.
Answer:
∠ A = 56°
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
2x + 3x + 40 = 180
5x + 40 = 180 ( subtract 40 from both sides )
5x = 140 ( divide both sides by 5 )
x = 28
then
∠ A = 2x = 2(28) = 56°

Researchers at a drug company are testing the duration of a new pain reliever. The drug is normally distributed with a mean duration of 240 minutes (4 hours) and a standard deviation of 40 minutes. The drug is administered to a random sample of 10 people. (Round means, standard deviations, and z-scores to the nearest hundredth, if necessary.)
The population mean of the sampling by the researcher is 240, the standard deviation is 40 and the z score is -2.
What is a mean?It should be noted that the mean is the average of the numbers that are given in a population. The z score is -2 as it measures the relationship between the means.
The probability that the drug will wear off between 200 and 220 minutes will be:
= P(Z < -1.58) - P(Z < -3.16)
= 0.0571 - 0.0008
= 0.0563.

Answer:
129
Step-by-step explanation:
The easiest thing to do would be an equation.
Since the value is decreasing by 6 each time you have -6x
-6x+?=?
Next thing you do, to get the y-intercept, would be to add 6 to the 309, which is the first term in order to get the zeroth term. This would make 315 the y-intercept
-6x+315=?
To solve for the 31st term, plug in 31 for x to get 129
