what is the expression for the probability when the disease D is present but the test says its not? P = Event that test is positive, D = Event disease is present
Answer:
[tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]
Step-by-step explanation:
Given
P = Test is positive
D = Disease is present
Required
Write an expression when disease is present but test says that the disease is not present
The above statement can be split to two
Disease is Present & Test is not positive
The first statement:
Disease is Present means D
The second statement
Test is not positive means not P
Mathematically;
not P means P' or [tex]P^c[/tex]
So, the required expression is: [tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

A seagull is flying at a height of 10 feet above ocean. The seagull dives into the water to catch a fish that is at a depth of 6 feet. What is the change in elevation of the seagull?
Answer:
The change in elevation of the seagull is -16 ft
Step-by-step explanation:
Displacement
The displacement, unlike distance, considers the direction of the lengths occurring in the systems.
To solve the problem, we need to set a zero-level reference. Let's assume the sea level as zero height, any position above this reference as positive, and any position below this reference as negative.
The seagull is flying at a height of 10 ft above the ocean. Thus, its position is positive +10 feet.
The seagull then dives into the water to catch a fish at a depth of 6 feet. This position is negative: -6 ft.
The change in elevation is found by subtracting the final elevation and the initial elevation:
change = -6 ft - 10 ft = -16 ft
The change in elevation of the seagull is -16 ft
The fifth term of an AP is 25 and the fifteenth term is 75 .Find the 10th term
Answer: I think it's 50
Step-by-step explanation:
5 = 25
15 = 75
Presumeably, 10 = 50
Answer:
50
Step-by-step explanation:
5th term=a+4d
10th term=a+9d
15th term=a+14d
since
5th term=25 and the 15th term=75
so we find the value of unknown 'd' with is the common difference
a+4d=25
a+14d=75
-10d=-50
d=5
after finding the value of d we can now find the value of 'a'
a+4(5)=25
a=5
hence the 10th term can be obtained
a+9d
5+9(5)=50
The circumference of a circle is 18.45 yards.
What is the radius of the circle, in yards? Round your answer to the nearest tenth.
Answer:
the radius is 2.94
Step-by-step explanation:
first divide the circumference by pie 3.14
the answer you get will be 5.8 is your diameter now divide 5.8 by 2 you get 2.935 round up your answer and it is 2.94 your radius

Reese is using a coin to predict the gender of the puppies born to her dog. According to Reese's model, which is the probability that a litter of 5 puppies will be all males? StartFraction 1 over 32 EndFraction StartFraction 1 over 16 EndFraction StartFraction 1 over 10 EndFraction One-half
Answer:
[tex]\frac{1}{32}[/tex]
Step-by-step explanation:
According to Reese's model, let the head of the coin represent male, and the tail represents female. The outcome can either be a male or a female.
Total outcome = 2
pr(male) = [tex]\frac{1}{2}[/tex]
pr(female) = [tex]\frac{1}{2}[/tex]
Therefore the probability of male equals the probability of females i.e [tex]\frac{1}{2}[/tex].
Therefore,
pr(a litter of 5 puppies will be males) = [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex]
= [tex]\frac{1}{32}[/tex]
According to Reese's model, the probability that a litter of 5 puppies will be males is [tex]\frac{1}{32}[/tex].
Answer:
I think that it's 1/32 if i'm not right pleas tell me.

Which of the following lists the sides of △DEF in order from shortest to longest?
Answer:
The 2nd option.
Step-by-step explanation:
Since Angle D is 68 degrees side EF would be the longest.
Side DF is the shortest side it is opposite the smallest angle.
Side EF is in the middle since opposite the next biggest angle.
Side EF is again the longest since Angle D is the biggest at 68 degrees.

B

Victoria moved into a new apartment and called to install her cable. They told her they charge $45 to install the cable box and $60 for each month of service. Which equation represents how much victoria will owe after x months?
Answer:
[tex]y=45+60x[/tex]
Step-by-step explanation:
Step one:
given data
The charge is $45 to install the cable box and $60 for each month of service
Required
The linear expression for the situation.
Step two:
let the number of months be x and let the total charges be y
Hence the expression for the total charges is
[tex]y=45+60x[/tex]

What are the real and complex solutions to the following equation? -2x^4+2x^2+4=0
Show all steps.
u=±1i or u=±√2
u=±2i or u=±√2
Answer:
x = ± i, x = ± [tex]\sqrt{2}[/tex]
Step-by-step explanation:
Given
- 2[tex]x^{4}[/tex] + 2x² + 4 = 0 ( divide through by - 2 )
[tex]x^{4}[/tex] - x² - 2 = 0
Use the substitution x² = u , then
u² - u - 2 = 0 ← in standard form
(u - 2)(u + 1) = 0 ← in factored form
Equate each factor to zero and solve for u
u - 2 = 0 ⇒ u = 2
u + 1 = 0 ⇒ u = - 1
Change back into terms of x, that is
x² = 2 ( take the square root of both sides )
x = ± [tex]\sqrt{2}[/tex]
x² = - 1 ( take the square root of both sides )
x = ± [tex]\sqrt{-1}[/tex] = ± i
x = ± [tex]\sqrt{2}[/tex] ← real solutions
x = ± i ← complex solutions
Sahai took $40 to the local carnival. The entrance fee to get into the carnival cost X dollars. Sahai paid for 5 people (including herself) to get into the carnival. Write an expression that represents the amount of money, in dollars, that Sahai had after she paid for the entrance fee for the 5 people.
Answer:
40-5x
Step-by-step explanation:
Sahai starts with 40 and loses 5 times the entrance fee, which is represented by x. So, 40-5x is the expression
