A new, simple test has been developed to detect a particular type of cancer. The test must be evaluated before it is put into use. A medical researcher selects a random sample of 1000 adults and finds (by other means) that 3% have this type of cancer. Each of the 1000 adults is given the test, and it is found that the test indicates cancer in 99% of those who have it and in 2% of those who do not. Based on these results, what is the probability of a randomly chosen person having cancer given that the test indicates cancer? Of a person having cancer given that the test does not indicate cancer?

A new car is purchased for 20000 dollars. The value of the car depreciates at 11% per year. To the nearest tenth of a year, how long will it be until the value of the car is 5700 dollars?
The number of years before the new car becomes $5700 is 11.4 years.
How long would it take the value of the car to become $5700?Depreciation is when the value of an asset declines with the passage of time.
Number of years = (In FV / PV) / r
r = rate of depreciation FV = future value of the carPV = purchase value of the car(IN 5700 / 20,000) / 0.11 = 11.4 years

Suzanne bought a sweater at the sale price of $35. The original cost of the sweater was $50. What percent represents the discount that Suzanne received when buying the sweater?
Answer:
She got a 30 % discount
Step-by-step explanation:
Take the original price and subtract the new price
50 -35 = 15
Divide by the original price
15/50
.30
Multiply by 100 to get the percent
.30 * 100 % = 30 %
She got a 30 % discount
which inequality represents the sum
of x and y is at most 15?
a.)x-y_>15
b.)x-y_<15
c.)x-y>15
d.)x-y<15
Answer:
x+y≤15
Step-by-step explanation:
We need to write an inequality that represents the sum of x and y is at most 15. At most in inequality is defined as less than or equal to i.e. ≤.
Sum of x and y means x+y
The inequality becomes,
x+y≤15
Hence, the correct option is (b).
The inequality which represents the sum of x and y is at most 15 is; Choice (b) x+y_<15
According to question;
We are required to determine the inequality that represents the sum of x and y is at most 15.In essence, the sum of x and y is either equal to or lesser than 15.
Therefore, the inequality is Choice B; x+y_<15

Answer:
x = 3
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other.
Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction
~
First, subtract 4 from both sides of the equation:
6x + 4 (-4) = 22 (-4)
6x = 22 - 4
6x = 18
Next, divide 6 from both sides of the equation:
(6x)/6 = (18)/6
x = 18/6
x = 3
3 is your value for x.

A net force acting on a 5.0 kg box produces an acceleration of 4.2 m/s2. What
acceleration will the same net force cause on a 2.8 kg box?
Answer:
14 N
Step-by-step explanation:
Let the mass of the box be m.
F = ma → F = 5 x 4.2 = 21 N
When mass = 2.8 kg, let the acceleration is a. For same force:
=> 21 = a x 2.8
=> 21/2.8 = a
=> 7.5 m/s² = a

Determine whether the lines x+ 7y= −3 and y = 7x + 25 are parallel, perpendicular, or neither. Justify your answer by showing all the needed work.
Answer:
perpendicular
Step-by-step explanation:
Rewrite the equations
y = (-1/7)x - 3/7 -- L1
y = 7x + 25 -- L2
Slope of L1 x Slope of L2 = -1/7 x 7 = -1
As a result, the two lines are perpendicular

A computer user has downloaded 19 songs using an online file-sharing program and wants to create a CD-R
with 9 songs to use in his portable CD player. If the order that the songs are placed on the CD-R is not
important to him, how many different CD-Rs could he make from the 19 songs available to him?
There are
possible CD-R's.
Answer:
That would be 19! / 10!, which is 33522128640
If to create a CD 9 songs are needed and user have 19 songs then he can create 33522128640 such CD's if solving through permutations.
What is permutations?It is basically an arrangement of objects in a certain order.It is expressed as n[tex]P_{r}[/tex] and it is equal to n!/(n-r)!.
How to calculate ways?We have been given that user have 19 songs and 1 CD is made from 9 songs so the number of CD's which can be made is basically the number of ways these 9 songs are arranged from 19 songs in CD's. So, the number of CD's will be 19[tex]P_{9}[/tex]=19!/(19-9)!
=19!/10!
=19*18*17*16*15*14*13*12*11*10!/10!
=19*18*17*16*15*14*13*12*11
=335322128640 CD's
Hence 335322128640 CD's can be made from 19 songs by the user.

Answer:
≈ 53.7° (Option 3)
Step-by-step explanation:
In the figure given above , the lengths of other two sides (excluding hypotenuse) are known to us. So , it would be convenient to use 'tan'.
Length of side opposite to angle 'x' = 15 cm
Length of side adjacent to angle 'x' = 11 cm
Using 'tan' formula - [tex]\tan x = \frac{Side \: opposite \: to \: x}{Side \: adjacent \: to \: x}[/tex] , lets solve this.
[tex]=> \tan x = \frac{15}{11}[/tex]
Using inverse tan function , lets find x.
[tex]=> x = {\tan}^{-1}(\frac{15}{11} )[/tex] ≈ 53.74°
