Complete question :
Lower-than-expected demand for LCD TVs has spurred manufacturers to cut prices in recent years. The average price P of a 32-in. LCD TV t years after 2005 can be approximated by P(t) 1052(0.793), where t0 corresponds to 2005 a) What was the average price of an LCD TV in 2005? in 2009? in 2011?
Answer:
1052 ; 416.01 ; 261.61
Step-by-step explanation:
Given the price function :
P(t) = t0(0.793)^t
P(t) = 1052(0.793)^t
Price in 2005 = 1052
The average price of LCD in 2005 is t0
t - t0 = 2005 - 2005 = 0
P(0) = 1052(0.793)^0 ;
P(0) = 1052 * 1 =
Price in 2005 = 1052
Price in 2009 :
t = 2009 - 2005 = 4
P(t) = t0(0.793)^t
P(4) = 1052(0.793)^4
P(4) = 1052 * 0.39534 = 416.0145
Price of LCD in 2009 = 416.01
Price in 2011
t = 2011 - 2005 = 6
P(t) = t0(0.793)^t
P(6) = 1052(0.793)^6
P(6) = 1052 * 0.248679 = 261.6103
Price of LCD in 2009 = 261.61

If a letter is randomly chosen, what is the probability of choosing a vowel??
Answer:
If we take "at random" to mean uniformly at random (which is the typical interpretation when there is no other information given) then the answer is actually FIVE out of eleven (not 4 out of eleven as the other answers give).
In English, the letter Y is considered a vowel when it makes the sound of a long E as it does in the word PROBABILITY. So the vowels are the A, the two I's, the O, and the Y -- a total of five of the eleven letters.
The only thing I have to add is that while "at random" is usually taken to mean uniformly at random, it need not mean this. For example, we could assign the probabilities in such a way that each letter is twice as likely as the letter before it. So "p" would have probability 1/2047 of being selected, "r" would have probability 2/2047, "o" would have probability 4/2047, and so on. Finally "y" would have probability 1024/2047. In this case, we'd add the probabilities of the five vowels to get a total probability of 1346/2047.
Answer:
The probability is 4/12 because there are 5 vowels. Just do the math.

Answer:
5 m
Step-by-step explanation:
(C is the hypotenuse)
A^2 + B^2 = C^2
4^2 + 3^2 = C^2
16 + 9 = C^2
25 = C^2 (Now square root both sides)
C = 5 m

Make q the subject of the formula p = 2q2 .
Answer:
q = ± p/2
Step-by-step explanation:
Given
p = 2q² ( divide both sides by 2 )
= q² ( take the square root of both sides )
± = q p/2
Step-by-step explanation:
[tex]p = 2q^2\\q^2 = \frac{1}{2}p\\q = \pm\sqrt{\frac{1}{2}p}\\q = \pm \frac{1}{2}\sqrt{2p} \qed[/tex] Q.E.D.

Answer:
Step-by-step explanation:
y=k[tex]\sqrt{x}[/tex]
60=k[tex]\sqrt{36\\}[/tex] =k6
k=60/6 =10
This is your equation
y=10[tex]\sqrt{x}[/tex]

In a class of 19 students, 12 are female and 13 have an A in the class. There are 4 students who are male and do not have an A in the class. What is the probability that a student chosen randomly from the class does not have an A?
answer is
6/19
× whats the point of this
The likelihood of selecting a classmate at random who does not have an A is 6/19.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
To find the probability of a student not having an A, we need to first find the total number of students who do not have an A.
The number of students who have an A is 13, so the number of students who do not have an A is:
19 - 13 = 6
Out of these 6 students, 4 are male and 2 are female.
So, the probability of choosing a student randomly who does not have an A is:
P(not A) = number of students without an A / total number of students
P(not A) = 6 / 19
Therefore, the probability of choosing a student randomly from the class who does not have an A is 6/19.

What is the radius of the copper circle?
9514 1404 393
Answer:
(1+√2)/2 ≈ 1.207 cm
Step-by-step explanation:
The angled flats are at 45°, so the length in the direction of a vertical or horizontal radius is (1 cm)/√2 = (1/2)√2 cm. The remaining length of that radius is half the length of a flat, so is 1/2 cm. The total length of the radius is ...
1/2 + 1/2√2 = (1+√2)/2 ≈ 1.207 cm
_____
In trigonometry terms, the length of the flat is ...
1 cm = 2(r)(tan(45°/2))
so the radius is ...
r = (1 cm)/(2·tan(22.5°))
r = (1/2)cot(22.5°) ≈ 1.207

Bank a charges a six dollar service fee and $.10 for each check written. Bank be charges $5.20 for each check written how many checks does a person need to write each month for the two banks to charge the same amounts in fees?
Answer:
A person needs to write each month 1.17 checks for the two banks to charge the same amounts in fees.
Step-by-step explanation:
You can write an equation in which the amount charged by bank a is equal to the amount charged by bank b. The amount bank a charges is 6 plus 0.10 for the number of checks written and the amount bank b charges is 5.20 for the number of checks written.
6+0.10x=5.20x, where x is the number of checks written
Now, you can solve for x to find the number of checks written where the two banks charge the same amounts in fees:
6=5.20x-0.10x
6=5.10x
x=6/5.10
x=1.17
According to this, the answer is that a person needs to write each month 1.17 checks for the two banks to charge the same amounts in fees.

A bird enclosure at a zoo was initially housed with 350 birds. The total population of birds in the enclosure is expected to increase every year by 5%.
Which function accurately describes the population of the birds in the enclosure, f(x), after x years?
A. f(x)=350(1.05)^x
B. f(x)=1.05(350)^x
C. f(x)=350(1.5)^x
D. f(x)=1.5(350)^x
Answer:
A
Step-by-step explanation:
The initial population is 350 so...
P = 350
The total population of birds in the enclosure is expected to increase every year by 5%
so r = 0.05
and time = X
we need to use the equation P(X) = P(1+r)^x
so by plugging in the values we get:
P(x) = 350(1.05)^x
so A is the correct answer
Find the area of the figure
Answer:
16.28 m^2
Step-by-step explanation:
The bottom portion of this figure is a trapezoid with lengths 4 m and 6 m.
Thus, the average length of this trapezoid is 5 m, and the height is 2 m. This leads to (5 m)(2 m) = 10 m as the area.
The upper portion is a semicircle of radius 2 m. The area of this semicircle is
A = (pi)r^2 / 2, which here is A = (pi/2)(2 m)^2, or approximately 6.28 m^2.
Thus, the area of the entire purple figure is 16.28 m^2.
Solve 6f-4g=1,6f-6g=5
Answer:
The solution is (-1/2, -2)
Step-by-step explanation:
Given 6f-4g=1,6f-6g=5, write these in columnar form:
6f-4g=1
6f-6g=5
Change all of the signs in the first equation:
-6f + 4g = -1
6f-6g=5
-------------------
-2g = 4, and so g = -2
Substituting -2 for g in either equation enables us to find f. Let's use the first equation: 6f - 4(-2) = 5 yields 6f + 8 = 5, or 6f = -3
Then f = -1/2 and g = -2. The solution is (-1/2, -2)
There were 25 problems in Mark's test. 92% of the problems he answered correctly. How many wrong answers were in Mark's test?
Answer:
2 incorrect answers
Step-by-step explanation:
If you take the percentage correct, you will notice its a particularly high score for the amount of questions. In this case, instead of using a really long theorem, its much simpler to just input numbers.
To find your score on a test out of 100%, you take your amount correct and divide it by the total number of questions, then multiply by 100.
If you take 24/25, you get 0.96, which if multiplied 100*0.96=96%
Now its simple, just go 23/25 to get 0.92, multiplied 100*0.92=92% correct, 25-23=2 so the amount of incorrect answers would be 2.
