Diagnostic tests of medical conditions can have several types of results. The test result can be positive or negative, whether or not a patient has the condition. A positive test (+) indicates that the patient has the condition. A negative test (−) indicates that the patient does not have the condition. Remember, a positive test does not prove the patient has the condition. Additional medical work may be required. Consider a random sample of 200 patients, some of whom have a medical condition and some of whom do not. Results of a new diagnostic test for the condition are shown.
Assume the sample is representative of the entire population. For a person selected at random, compute the following probabilities. (Enter your answers as fractions.) Test Result Test Result Column Total Condition Present 105 24 129 Condition Absent 25 46 71
(a) P(+ condition present): this is known as the sensitivity of a test.
(b) P(- | condition present); this is known as the false-negative rate.
(c) Pcondition absent); this is known as the specificity of a test.
(d) P(+ | condition absent); this is known as the false-positive rate
(e) Prcondition present and +); this is the predictive value of the test

Answer:

150

Step-by-step explanation:

Answer:

150 cents

Step-by-step explanation:

if 1 dollar equals 100 cents then 1 dollar and 50 cents is one hundred fifty cents

The given expression is a difference of squares, so we have

16 (a + b)² - 49 (a - b)² = 4² (a + b)² - 7² (a - b)²

… = (4 (a + b))² - (7 (a - b))²

… = (4 (a + b) - 7 (a - b)) (4 (a + b) + 7 (a - b))

… = (4a + 4b - 7a + 7b) (4a + 4b + 7a - 7b)

… = (-3a + 11b) (11a - 3b)

Step-by-step explanation:

Answer:

Store C has the lowest price of $7.00

Step-by-step explanation:

Store A's sale gets you 15% off the shoes. 15% of 35 is $25.50

Store B's sale gets you $5.00 off the shoes. $35.00 - $5.00 = $30.00

Store C's sale gets you 1/5 off the shoes. 1/5 of $35.00 is $7.00

That means that the only true statement is the Store C's shoes are $7.00

2/3

Step-by-step explanation:

66.66 percent is closest to the fraction 2/3.

Answer: 44%

Step-by-step explanation:

There are 25 squares in the rectangle. This means that the percentage of each square is:

= 1/25 * 100

= 4%

There are 11 shaded squares so the percentage represented is:

= 11 * 4%

= 44%

Answer: 7 ; 26 ; 123

Step-by-step explanation:

Min __Q1 __ Median ___ Q3 __ Max

7____ 72 ____79 ______86__ 123

Given the 5 number summary information :

The Outlier :

Lower bound : Q1 - (1.5 * IQR)

Upper bound : Q3 + (1.5 * IQR

IQR = Q3 - Q1 = (86 - 72) = 14

Lower = 72 - (1.5 * 14)

Lower boundary = 51

Upper boundary = 86 + (1.5 * 14)

Upper boundary = 86 + 21 = 107

Values below 51 and values greater Than 107 are outliers.

Hence, 7, 36 and 123 are outliers

Step-by-step explanation:

Larry  Fitzgerald caught 109, John Brown caught  65 and  Michael Floyd caught 52.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

An equation is a set of variables that are constrained through a situation or case.

Let's say the number of passes that Larry caught = L

Let's say the number of passes that John caught = J

Let's say the number of passes that Michael caught = M

Given,

Cardinals caught a total of 226 passes.

So,

L + J + M = 226

Larry Fitzgerald caught 44 more passes than John Brown

L = 44 + J

Michael Floyd caught 13 fewer catches than John Brown.

M = J - 13 ⇒ J = M + 13

Substituting this J into the above equation,

M = 52 , L = 109 and  J = 65

Hence, Larry  Fitzgerald caught 109, John Brown caught  65 and  Michael Floyd caught 52.

Answer:

Each has to work 5 hours and earn $42

Step-by-step explanation:

Let m and h represent hours Nai spends mowing and hauling, respectively. Then (m+h) will be the number of hours Priya spends babysitting. In order for their earnings to be equal, we must have ...

 7m +14h = 8.40(m+h)

 5.60h = 1.40m . . . . . . . . subtract 7m+8.40h

 m = 4h . . . . . . . . . . . . . . divide by 1.40

Then the total number of hours worked by either person is ...

 m + h = (4h) +h = 5h

If only whole numbers of hours are worked, then the smallest number of hours that will make earnings equal is 5h, with h=1, or 5 hours. In that time, each will earn 5×$8.40 = $42.

Each must work 5 hours and earn $42 before they go to the movies.

__

Nai will work 4 hours mowing and 1 hour hauling.

Each must work 5 hours and earn $42 before they go to the movies. Mai will work 4 hours mowing and 1 hour hauling.

Two or more expressions with an Equal sign is called as Equation.

Let m and h represent hours Mai spends mowing and hauling, respectively. Then (m+h) will be the number of hours Priya spends babysitting.

In order for their earnings to be equal, we must have

7m +14h = 8.40(m+h)

subtract 7m+8.40h

5.60h = 1.40m

Divide by 1.40

m = 4h

Then the total number of hours worked by either person

m + h = (4h) +h = 5h

If only whole numbers of hours are worked, then the smallest number of hours that will make earnings equal is 5h, with h=1, or 5 hours. In that time, each will earn 5×$8.40 = $42.

Hence, Each must work 5 hours and earn $42 before they go to the movies. Mai will work 4 hours mowing and 1 hour hauling.

Answer:

(6,9) and (7,9) - assuming the graph only has a single quadrant and the rectangle is vertical

Step-by-step explanation:

We know that the distance between (6,1) and (7,1) is one unit. Because a rectangle has 2 pairs of equal sides, we know that the distance between the 2 missing coordinates is equal to one. We then add these two units. Because the rectangle has a parameter of 18 units, we then have to subtract these 2 units from the total, leaving us with 16 units for both sides. We then divide 16 by 2 because there are 2 sides, leaving us with 8 units for each side. Assuming we are working with a coordinate graph (with only one quadrant instead of 4 on a coordinate plane), and assuming the rectangle is vertical, the missing coordinates should be 8 units above the coordinates you were given. Hope this helps! :)

Question:

The grocery store has 20% off from the original price on cereal. The equation for finding the sale price would be y = x - (.20x). What is the sale price if the cereal cost $4.00?

Answer:

The sales price is $3.20

Step-by-step explanation:

Given

[tex]y = Sales\ Price[/tex]

[tex]x = Cost[/tex]

[tex]y = x - (0.20x)[/tex]

Required

Determine y when x = 4.00

To do this, we simply substitute 4.00 for x in [tex]y = x - (0.20x)[/tex]

[tex]y = 4.00 - (0.20 * 4.00)[/tex]

[tex]y = 4.00 - 0.80[/tex]

[tex]y = 3.20[/tex]

Hence, the sales price is $3.20

Answer:

No, negative

Step-by-step explanation:

the sign of the product of two numbers with opposite signs is a negative.

-5 * 4 = -20

5 * -4 = -20

The statement "the sign of the product of two numbers with opposite signs is a positive" is false.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that:

The statement is:

The sign of the product of two numbers with opposite signs is a positive

Let x be the number and x > 0

And let y be the number y < 0

The product of the above two numbers:

xy = -(A)  because x > 0 and y < 0

Here A is the positive real number or A > 0

The sign of the product of two numbers with opposite signs is negative.

Thus, the statement "the sign of the product of two numbers with opposite signs is a positive" is false.
