Situation: Find the substance's half-life, in days. Round your answer to the nearest tenth. A 50 gram sample of a substance that's used to treat thyroid disorders has a k- value of 0.1133. Enter the correct answer. N = Noe -kt DONE No = initial mass (at time t = 0) 1? N = mass at time t k = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days
Find the substance's half-life , in days.
Round your answer to the nearest tenth.
Answers
Answer:
The substance's half-life is 6.1 days.
Step-by-step explanation:
The half-life of the substance can be calculated by knowing the constant decay:
[tex] t_{1/2} = \frac{ln(2)}{k} [/tex]
k: is the decay constant = 0.1133 d⁻¹
Hence, the half-life is:
[tex] t_{1/2} = \frac{ln(2)}{k} = \frac{ln(2)}{0.1133 d^{-1}} = 6.1 d [/tex]
Therefore, the substance's half-life is 6.1 days.

At a recent meeting at the American College of Asthma, Allergy, and Immunology, researchers reported that allergy vaccinations are effective in treating sinusitis (inflammation of the membrane lining the facial sinuses) in individuals predisposed to allergies. Specifically, the researchers reported that 98% of individuals predisposed to allergies find relief from their sinusitis after allergy vaccinations. Suppose that this number is accurate and that 150 individuals predisposed to allergies are chosen at random and given allergy vaccinations.
A. Estimate the number of individuals in the random sample who do not find relief from their sinusitis by giving the mean of the relevant distribution (that is, the expectation of the relevant random variable).
B. Quantify the uncertainty of your estimate by giving the standard deviation of the distribution.
Answers
Solution :
Here we can use the Binomial distribution, as there are only two possible outcomes.
The given data:
n = 150
q = 98%
= 0.98
p = probability of not finding relief = 1 - 0.98
= 0.02
A). The number of the individuals who do not find any relief from sinusitis is :
E(x) = np
= 150 x 0.02
= 3
B). The uncertainty of my estimate is = [tex]$\sqrt{npq}$[/tex]
[tex]$=\sqrt{150 \times 0.02 \times 0.98}$[/tex]
= 1.716

An isosceles triangle has two identical angles.
The three angles need to add up to 180 degrees.
If one angle is 100 then the other two angles added together need to equal 180-100 =‘80 degrees.
Since two angles need to be the same the other angles are 80 / 2 = 40 degrees each.
The answer is 40
Answer:
A. first answer on the left.
Step-by-step explanation:
If one of the angles is 100 then if the triangle is isosceles then the two remaining angles have to be either 100 and - 20 (which is impossible because at this level of math there is no such thing as an angle with a measure of - 20).
The minus 20 comes from every triangle having 180 degrees. 100 + 100 adds to 200, which means the third angle has to be the impossible measure of - 20.
The other possibility is that the given angle of 100 is the top angle and that leaves 80 degrees for the two isosceles angles.
2x = 80
x = 80/2
x = 40
The only possible answer is 40 - 40 - 100

Harry had 3 packages of gum. Altogether there were
24 pieces of gum. If all packages have the same
number of sticks of gum, how many sticks of gum are
on each package?
Answers
Given,
Number of pieces = 24
Number of packages = 3
Each package has the same number of pieces.
So,
Number of pieces in 1 package
= Number of pieces / Number of packages
= 24 / 3
= 8
