An experimental drug has been shown to be 75% effective in eliminating symptoms of allergies in animal studies. A small human study involving six participants is conducted. What is the probability that the drug is effective on half of the participants?

Answers

Answer 1

Answer:

[tex]P(x=3) = 0.1318[/tex]

Step-by-step explanation:

The question illustrates a binomial distribution and the given parameters are:

Given

[tex]n = 6[/tex] -- sample size

[tex]p = 0.75[/tex] --- probability of success

[tex]r = 3[/tex] --- half of the participant

Using the binomial probability formula, we have:

[tex]P_x = ^nC_xp^x(1-p)^{n-x}[/tex]

For x = 3, the probability is:

[tex]P(x=3) = ^6C_3*0.75^3 * (1-0.75)^{6-3}[/tex]

[tex]P(x=3) = 20*0.75^3 * 0.25^3[/tex]

[tex]P(x=3) = 0.1318[/tex]

(Statistics) A local gym collects data on the number of memberships it sold in each month last year compared to the number sold in each month this year. For example, the January sales from last year are compared to the January sales from this year. Which of the following best describes the first step needed to simulate this data?

(Answer choices shown in photo. Will report fake/spam answers. Thanks for the help).

Answers

Answer:

Determine the proportion of months where memberships sold decreases,

increases and remained the same.

Step-by-step explanation:

I just took the test and got it correct.

The first step needed to simulate this data is:

Assign each month a digit from 1 to 24 to account for the 24 total months being compared.

Option B is the correct answer.

What is simulating data?

Simulating data means creating artificial data that mimics the characteristics of real data.

This artificial data is generated by using a model or a set of rules that describe how the data might be generated under certain conditions.

We have,

The first step needed to simulate this data is to assign each month a digit from 1 to 24 to account for the 24 total months being compared.

This will allow for an easy comparison of the sales data from last year and this year.

Once each month has been assigned a digit, the data can be organized and analyzed to determine the proportion of months where memberships sold decreased, increased, and remained the same, as well as the mean monthly sales from last year and this year.

Finally, random digits can be assigned to each sales figure from last year and this year to create a simulated data set that can be used for further analysis and modeling.

Thus,

The first step needed to simulate this data is:

Assign each month a digit from 1 to 24 to account for the 24 total months being compared.

which shows 2÷3 written as a fraction? (options) a. 2/3 b. 3 1/2 c. 3/2 d. 2 1/3​

Answers

Answer:

A. 2/3

Step-by-step explanation:

Fraction is another way to divide , So in some math problems they want you to either flip the fraction or divide the numbers .

Option A is correct, the expression 2÷3 written as a fraction is 2/3.

What is Fraction?

A fraction represents a part of a whole.

We have to write  2÷3  as a fraction.

Two divided by three.

We have to split the number two by three parts.

We know that any division expression can be written as a fraction, the numerator is a part and denominator is a whole.

Two is the numerator and three is the denominator.

The numerator represents the part and three represents the whole.

This we can write in fraction as 2/3.

Two by three is the fraction form of two divided by three.

Where as [tex]3\frac{1}{2}[/tex], is not a fraction, it is a mixed number.

3/2, is not equivalent to 2 ÷ 3, it represents the fraction one and a half and [tex]2\frac{1}{3}[/tex] is not equivalent to 2 ÷ 3, it represents the mixed number two and one-third.

Hence, Option A is correct, the expression 2÷3 written as a fraction is 2/3.

What is (7-2)^2+3/ 1/6
( / ) this means divide and (^) that means to the power

Answers

Answer:
43

Explanation:
To start off you always handle the whatever's in your parentheses. 7-2 is 5.
Now your equation should look like this-
(5)^2 +3/1/6
5 to the power of 2 is 25 (5 times 5)
so now instead of 5 you have 25:
25 +3/1/6

To divide fractions you first have to make 3 and fraction so just put a one below it so it's still it's full value: 3/1
When dividing fractions you actually end up multiplying, you keep the first fraction the same (3/1) and you flip the second one (1/6 which is now 6/1) and then you multiply.
3/1 * 6/1 equals 18/1 which actually just equals 18 and then you get 25 + 18 from the parentheses and that equals 43 :)

Write two mixed numbers so that all rules are applied:

2. The difference of the numbers is equal to the smaller number.
3. The sum of the numbers is natural number

Answers

Answer:

Step-by-step explanation:

“One number is larger than the other by 4 2/3”

x = y + 4⅔

“The difference of the numbers is equal to the smaller number.”

x-y = y

x = 2y

y + 4⅔ = 2y

y = 4⅔

x = 2y = 9⅓
