According to the Question , diameter of circle is 16 inches. We need to find the area in terms of pi (π) . We know the area of circle as product of pi and square of radius . Therefore ,
[tex]\to\tt \orange{ Area = \pi r^2 } \\\\\tt \to Area = \pi (8 \ in.)^2 \\\\\tt\to \boxed{\orange{\tt Area = 64\pi in^2 }}[/tex]
Answer:
[tex]64\pi[/tex]
Step-by-step explanation:
diameter => D = 2r
r = D/2 = 16/2 = 8
area =
[tex]\pi \times r {}^{2} [/tex]
=
[tex]64\pi[/tex]

The test to determine the presence of a certain virus in a pigeon is 97% accurate for a pigeon that has the virus and 99% accurate for a pigeon that does not have the virus. In a given population, 1.5% of the pigeons are infected.
Do not round your answer.
The probability that a randomly selected pigeon gets an incorrect result is
Before finding the probabilities, we need to find all possible outcomes, and it's probabilities.
Doing this, we get:
The probability that a randomly selected pigeon gets an incorrect result is 0.0103 = 1.03%.
Possible outcomes:
Pigeon has the virus(1.5% probability) and gets an accurate test, showing the presence of the virus(97% probability).
Pigeon has the virus(1.5% probability) and gets an inaccurate test, not showing the presence of the virus(100% - 97% = 3% probability).
Pigeon does not have the virus(100 - 1.5 = 98.5% probability) and gets an accurate test, not showing the presence of the virus(99% probability).
Pigeon does not have the virus(98.5% probability) and gets an innacurate test, showing the virus(100 - 99 = 1% probability).
Probability of incorrect result:
Has the virus and test negative: 0.03 of 0.015
Does not have the virus and test positive: 0.01 of 0.985
Thus:
[tex]p = 0.03\times0.015 + 0.01\times0.985 = 0.0103[/tex]
The probability that a randomly selected pigeon gets an incorrect result is 0.0103 = 1.03%.

a) IJ is median
IJ = 1/2(HG + EF)IJ = 1/2(8 + 12) = 10 cmb) I is midpoint of HE, therefore, HI = IE
Substitute values and solve for x:

Answer:
188.24 (rounded)--- 188.2
Step-by-step explanation:
You want to first find the area of all the the different shapes you have...
you have 2 semicircles A= πr²/2 (because it is /2 you don't really need that because in the end you are going to *2 so just make the equation A= πr²)
you have a rectangle A= b*h
you have a triangle A = b*h/2
Semicircles: A= πr² = (3.14) 4² = (3.14*16) = 50.24
rectangle: A = b*h = 12*8 = 96
Triangle: A = b*h/2 = 12 * 7/2 = 84/2 = 42
then you add them up
50.24 + 96 + 42
= 188.24

Assume that the readings at freezing on a bundle of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find the probability of obtaining a reading greater than -0.084°C.
P(Z>-0.084)
Answer:
0.53347
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score = -0.084 °C
μ is the population mean = 0 °C
σ is the population standard deviation = 1°C
Z score =x - μ/σ
= -0.084 - 0/1
= -0.084
Probability value from Z-Table:
P(x<-0.084) = 0.46653
P(x>-0.084) = 1 - P(x<-0.084) = 0.53347
The probability of obtaining a reading greater than -0.084°C = P(x > -0.084) =
is 0.53347

Answer:
c = 88
Step-by-step explanation:
c = 180 - a - b
c = 180 - 43 - 49
c = 137 - 49
c = 88
Answer:
c= 88
Step-by-step explanation:
What you want to do is take (a) which it says is 43 and (b) which it says is 49 and plug them into the equation. Here it says c = 180 - a - b so what you would do is take c=180-43-49 or c=88.

Calculate the distance between the points E=(-6,8) and N=(-1,5) in the coordinate plane. Give an exact answer (not a decimal approximation).
Answer:
6 units
Step-by-step explanation:
The formula for calculating the distance between two points is expressed as;
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Given the coordinate points E=(-6,8) and N=(-1,5)
[tex]EN = \sqrt{(5-8)^2+(-1+6)^2}\\EN = \sqrt{(-3)^2+(5)^2}\\EN = \sqrt{9+25}\\EN = \sqrt{34}\\EN = 5.8\\EN \approx 6[/tex]
Hence the distance between the points is approximately 6 units

Cos n = 12/37 = 0.32
Sin m = 12/37 = 0.32
Sin n = 35/37 = 0.94
tan m = 12/35 = 0.34
tan n = 35/12 = 2.91
