A rapid strep test is often given in a clinical setting so that, if needed, antibiotics can begin as soon as possible. Researchers at Cochrane.org evaluated the effectiveness of rapid strep tests and found that one type had a sensitivity (ability to correctly detect people with strep) of 85.4% and a specificity (ability to correctly identify people who do NOT have strep) of 95%
Fill in the following chart, assuming that you have a group of 10,000 people, 15% of whom actually have strep throat.
Patient is given a rapid strep test
Result is positive Result is negative totals
Has strep throat
Does not have strep
Totals 10,000
For a population of patients similar to those described in the stem of this problem, use the chart find each of the following probabilities. Write you answer as an abbreviated probability statement with your answer to four decimal places without using a percent symbol. For example, P(strep) = 0.15
A) The probability that a randomly chosen patient has strep throat and tests positive
B) The probability that a randomly chosen patient tests positive for strep throat.
C) The probability that a randomly chosen person actually has strep throat, given that they have tested positive.

Step-by-step explanation:

Follows are the table to this question:

                                        [tex]positive \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ negative \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ total[/tex]

Hjqjzjzj is a complete* of the following elements has the largest atomic size in the world is the difference between human rights

Answer:

We know:

A+2B=777

2A+B=789

 

Let's rearrange the first equation to solve for A:

A=777-2B

 

Now let's plug 777-2B in for A in the second equation, and solve for B:

2(777-2B)+B=789

1554-4B+B=789

1554-789=3B

765=3B

B=255

 

Now we can substitute 255 in for B in the first rearranged equation, and solve for A:

A=777-2(255)

A=777-510

A=267

So candy bar A has 267 calories, and candy bar B has 255

Jeff is designing the seating arrangement for a concert in his high school theater. To give everyone a good view, each row must have 5 more seats than the row before it, and the 1st row can only have 12 seats. Explain to Jeff how to create an equation to predict the number of seats in any row. Then, using your equation, show your work to determine the number of seats in row 25.

Answers

Answer:

There will be 132 seats in row 25

Step-by-step explanation:

1st term = 12

common difference = 5

f(x) = 12 + 5(x - 1)

f(25) = 12 + 5(25-1)

f(25) = 12 + 5(24)

f(25)= 12+120

f(25)=132

There will be 132 seats in row 25

The number of seats is 137 with the general equation [tex](12+5n)[/tex] seats

General equation:

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

Let the row number is [tex]n[/tex]

The number of seats in the first row is 12

As per the plan, each row shall have 5 more seats.

So, in the first row seats=12

In the second row seats=[tex]12+5[/tex]

In the third row seats=[tex]12+2\times5[/tex]

[tex]n^{th}[/tex]  row seats=[tex]12+5n[/tex]

So, the number of seats in any row is [tex]12+5n[/tex]

Where [tex]n[/tex] is the row number

Now, for 25 rows, [tex]n=25[/tex] then,

The number of seats is,

[tex]12+5\times25=137[/tex]

Option B. 4

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle θ = 60 °

Opposite (Fe) = 4√3

Adjacent (DE) = x

The value of x can be obtained by using the Tan ratio as illustrated below:

Tan θ = Opposite / Adjacent

Tan 60 = 4√3 / x

√3 = 4√3 / x

Cross multiply

√3 × x = 4√3

Divide both side by √3

x = 4√3 /√3

x = 4

Thus, the length of DE is 4

Eight minus a number divided by three is greater than or equal to eleven Suppose that you are running a business and you need some extra space for one year. Your bank offers you a loan of $200,000 at 0% interest. You consider borrowing this amount, buying the building, using it for one year, and then selling the building to pay back the loan. Unfortunately, the economy in which you are operating is experiencing deflation at a rate of 10% per year.After one year, you should be able to sell the building for _.Suppose that owning the building for a year would earn you $5,000. To decide whether or not you will be better off by owning it for one year and then selling it, you sought advice from three different people: (1) Your brother says that you should not buy the building because in one year it will cost you $100,000. (2) Your accountant says that you should definitely buy the building because you can borrow $100,000 at zero interest while the building will generate $5,000 in extra income. Then when you sell it, you will be $5,000 richer. (3) Your bookkeeper says that if you sell the building in a year, you will have to come up with more money to pay off the loan than you will make in extra income. Keeping in mind that the economy experiences deflation at the rate of 10%, yourbookkeeper is right because: ________a. When the nominal interest rate is zero, you do not incur any cost when you take out a loan. b. The extra income you will earn will be less than the cost of owning the building for the year. c. When the nominal interest rate is zero, the cost of a building is its full purchase price 6. The distribution of electrical charges of an atom to form a bond.
