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

Which statement cannot be justified by one of the properties of real numbers?
A. (a + b) + c = a + (b + c)
B. a – (b÷c) = (a – b) ÷c
C. (ab)c = a(bc)
D. (a + b) + 0 = 0 + (a + b)

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

a. What is asked in the probleme
b. What are given
d. What is the number sentence?
e. Show your solution and answer:​

Answers

Answer:

A) Number of mango trees

B) Percentage of coconut trees = 60%

Total number of trees = 2230 trees

C)number of mango trees = 40% × 2230

D) 892 mango trees

Step-by-step explanation:

A) What is asked is the number of mango trees

B) We are given;

Percentage of coconut trees = 60%

Total number of trees = 2230 trees

C) Number sentence is defined as when we use an equation or inequality to describe an expression using numbers and signs.

We have percentage of coconut trees = 60%.

Thus, percentage of mango trees = 100% - 60% = 40%

In this case, the number sentence is; number of mango trees = 40% × 2230

D) number of mango trees = 40% × 2230 = 892

If a ball is dropped on the ground from a height of h meters, then the ball reaches the ground with the velocity 4.43h m/sec.

Find the velocity with which a ball reaches the ground when it is dropped from a height of 32 m.

Answers

Answer:

v = 141.76 m/s

Step-by-step explanation:

Given that,

The ball reaches the ground with a velocity of 4.43h m/sec.

We need to find the velocity of the ball at a height of 32 m.

Since, v = 4.43h

Put h = 32 m in the above expression.

v = 4.43(32)

v = 141.76 m/s

So, the velocity of the ball is equal to 141.76 m/s.

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.

I hope it helps you!
