Step-by-step explanation:
Suppose you go fishing at a local stream that is known for its rainbow trout. The stream has rules about rainbow trout. If they are unusually small, they have to be released back in the stream. All others can be kept or released. If they are unusually large, you're definitely going to want to take a picture for the local fish shop. Rainbow trout in this steram have a mean length of 18.3 inches and a standard deviation of 3.2 inches. Their lengths follow a normal distribution.
Round to the fourth as needed.
You just caught a fish that is 22.78 inches .

Brad, a teenager, saves up his monthly allowance over a period of six months to buy a pair of high-resolution headphones. He lends his friend, Jorge $10 from his savings. If Brad has $272 now.
Then a monthly allowance of Brad will be given as,
⇒ ($272 - $10) / 6
⇒ $262 / 6
⇒ $43.67
The amount of monthly allowance of Brad will be $43.67 per month.

In 1982 John Hinckley was on trial, accused of having attempted to kill the then US President Ronald Reagan. Hinckley was found not guilty by reason of insanity. The defense psychiatric reports found him to be insane while the prosecution reports declared him legally sane. In particular, the defense sought to establish that brain scan results like John Hinckley's appeared in a higher percentage of schizophrenics than of normal people his age.
During Hinckley's trial, an expert witness, Dr. Weinberger, told the court that when individuals suffering from schizophrenia were given computerized axial tomography (CAT) scans, the scans showed brain atrophy in 30% of cases compared with only 2% of scans done on normal people. Health records show that 1.5% of the people in the United States suffer from schizophrenia. Hinckleys CAT scan showed brain atrophy. Calculate the probability that Hinckley suffered from schizophrenia given his CAT scan showed brain atrophy.
Answer:
O.186 or 18.6%
Step-by-step explanation:
Let s = event of schizophrenia
B = brain atrophy
From our question we have:
P(s) = probability of those suffering from schizophrenia = 1.5% = 0.015
P(B|S) = probability of brain atrophy = 30% = 0.30
P(S') = 1 - 0.015 = 0.985
P(B|S') = 2% = 0.02
Probability Hinckley suffered from schizophrenia
= P(S|B) = P(B|S)P(S)/P(B|S)P(S)+P(B|S')P(S')
= (0.30x0.015)/(0.30)*(0.015)+(0.02)(0.985)
= 0.0045/0.0045+0.0197
= 0.0045/0.0242
= 0.185950
This is approximately 0.186 or 18.6%
How is multiplying complex numbers different
from adding or subtracting complex numbers?
Let P and Q be two complex numbers such that
P = a+bi
Q = c+di
Where a,b,c,d are real numbers and i = sqrt(-1).
This means i^2 = -1.
-------------------
Adding P and Q means
P+Q = (a+bi)+(c+di)
P+Q = a+bi + c+di
P+Q = (a+c) + (bi+di)
P+Q = (a+c) + (b+d)i
As you can see, we just add the corresponding components together.
-------------------
Subtraction is a similar story.
P-Q = (a+bi)-(c+di)
P-Q = a+bi - c-di
P-Q = (a-c) + (bi-di)
P-Q = (a-c) + (b-d)i
We subtract the corresponding components
-------------------
Multiplication is a bit more complicated.
We'll use the FOIL rule
P*Q = (a+bi)*(c+di)
P*Q = a*c + a*di + bi*c + bi*di
P*Q = a*c + ad*i + bc*i + bd*i^2
P*Q = a*c + ad*i + bc*i + bd*(-1)
P*Q = a*c + ad*i + bc*i - bd
P*Q = (ac - bd) + (ad*i + bc*i)
P*Q = (ac - bd) + (ad + bc)i
Unfortunately multiplication isn't as simple as addition or subtraction, but we can at least make a tidy formula for it. You could also use the box method to visually organize the terms into a table to help multiply out P and Q.

Answer:
20%
Step-by-step explanation:
You would have to add 1200 and 300 to get the total amount of students which would be 1500.
Then put 1500 as the denominator and 300 as the numerator since we're talking about the number of students that did NOT wear their school colors. our fraction should then be 300/1500.
If you cross out 2 zeros on both numbers, you'll get 3/15. if you reduce that you get 1/5. 1/5= 20%

Please help shouldn't be 38?
Answer:
No it is D.52
Step-by-step explanation:
The angle has to equal 180 degrees.
180-76=104
52 time 2 equals 104
104=104
Answer:
[tex]\boxed {\tt D. \ x=52}[/tex]
Step-by-step explanation:
The 2 angles are 2x and 76. They are on a straight line together. Therefore they are supplementary and add to 180 degrees.
[tex]2x+76=180[/tex]
Solve for x by isolating x on one side of the equation.
76 is added to 2x. The inverse of addition is subtraction. Subtract 76 from both sides of the equation.
[tex]2x+76-76=180-76\\2x=180-76\\2x=104[/tex]
x is multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.
[tex]2x/2=104/2\\x=104/2\\x=52[/tex]

What is the slope of the line through (-3, 3) and (-1, -1)?
Answer:
[tex]m=-2[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in the 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{-1-3}{-1-(-3)}[/tex]
[tex]m=\frac{-4}{-1+3}[/tex]
[tex]m=\frac{-4}{2}[/tex]

Michael lives 2 3/5 miles away from the school Sarah lives 1/2 as long as Michael how far does Sarah live from the school
Answer:
Let's see what to do buddy...
Step-by-step explanation:
[tex]2 \frac{3}{5} miles = \frac{10}{5} + \frac{3}{5} \: miles = \frac{13}{5} \: miles \\ [/tex]
So Michael lives 13/5 miles away from the school.
_________________________________
Sarah lives 1/2 as long as Michael.
So the distance from the school of where Sarah's house located is 1/2 distance from the school of where Michael's house located.
Which means :
[tex] \frac{13}{5} \div 2 = \frac{13}{5} \times \frac{1}{2} = \frac{13}{10} \\ [/tex]
And we're done.
Thanks for watching buddy good luck.

Find all solutions of 5−4 secx = −3 on the interval [0, 2π).
Answer:
[tex]\theta=\dfrac{\pi }{3}\\\\\theta=\dfrac{5\pi }{3}[/tex]
Step-by-step explanation:
[tex]\theta = x[/tex]
[tex]5-4 \sec (\theta) = -3[/tex]
[tex]-4 \sec (\theta) = -3-5[/tex]
[tex]-4 \sec (\theta) = -8[/tex]
[tex]\dfrac{-4 \sec (\theta)}{-4} =\dfrac{-8}{-4}[/tex]
[tex]\sec (\theta)=2[/tex]
Once
[tex]\sec(\theta)=\dfrac{1}{\cos(\theta)}[/tex]
[tex]\sec (\theta)=2 \implies \dfrac{1}{\cos(\theta)}=2 \implies \cos(\theta)=\dfrac{1}{2}[/tex]
The solutions for [tex]\cos(\theta)=\dfrac{1}{2}[/tex] are
[tex]\theta=\dfrac{\pi }{3}+2\pi n, n \in \mathbb{Z}\\\\\theta=\dfrac{5\pi }{3}+2\pi n, n \in \mathbb{Z}[/tex]
But once the interval for the solution was given,
For [tex][0, 2\pi)[/tex]

Kevin went to see his favorite sport team play. His car can go 320 miles on one tank of gas. If he used 50% of a full tank of gas how many miles will he travel
Answer:
To find the percentage of something you must multiply it by that number divided by 100. So if it were 25% then you would times 300 by 0.25.
in this case though it is 40% of three hundred, so you would make it a decimal and times 300 by 0.4. which would result in 120 miles

Identify the domain and range of the relation. {(-9,2), (-4, 2), (3, 2), (9,2)
Answer:
Domain: - 9, - 4, 3, 9
Range: 2
Step-by-step explanation:
The domain is the first coordinate of an ordered pair. This means that the domain is going to be x. The range is the second coordinate of an ordered pair. This means that the range is going to be y. Since all of the second coordinates are 2 you only have to put 2 once. The domain of the set of ordered pairs is - 9, - 4, 3, 9.
