Answer: 45°
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:
Median: b
Altitude: c
Angle bisector: a
Perpendicular bisector: d
Step-by-step explanation:
Which of the following describes the data set?
6, 7, 11, 14, 20, 30, 35
A. Minimum = 14
First quartile = 6
Median - 25
Third quartile = 35
Maximum = 35
B. Minimum = 35
First quartile = 11
Median = 25
Third quartile = 38
Maximum = 6
C. Minimum = 6
First quartile = 7
Median = 14
Third quartile = 30
Maximum = 35
D. Minimum = 6
First quartile = 35
Median = 25
Third quartile = 11
Maximum = 30

Angle formed by two chords is the half of the sum of the intercepted arcs:
7x + 3 = 1/2(152 + 78)7x + 3 = 1157x = 112x = 112/7x = 16What is the slope for this question?
Answer:
[tex]-1[/tex]
Step-by-step explanation:
This is a really nice line that goes through a lot of grid points (where the lines intersect).
One easy way to find the slope is the phrase "rise over run." "Rise" is the name for vertical motion from point-to-point. "Run" is the name for horizontal motion from point-to-point.
Pick two easy points on the line, say (0, 0) and (1, -1).
If you go from (0, 0) to (1, -1), the rise is -1 -- because you went DOWN 1 unit.
The run is 1 -- because you went RIGHT 1 unit.
[tex]\frac{\text{rise}}{\text{run}} =\frac{-1}{1} =-1[/tex]
The slope is -1.
Cool fact: You'll get the same value if you use any two points on the line.

The half-life of a radioactive kind of neodymium is 11 days. If you start with 2,616 grams of it, how much will be left after 22 days?
Answer:
654 grams
Step-by-step explanation:
When you set up this equation you want the number of grams you start with, 2616, and the factor by which it is decreasing, which is half, or 1/2. Because the half life is 11 days, but you want to find the amount left over after 22 days, you can make 22/11 as the exponent on the 1/2. The equation should look like this : 2616(1/2)^22/11. With these kinds of equations you always want to multiply the starting value by the factor of increase/decrease, and raise that factor to the time eclipsed divided by the set time(like the 11 day half life).
Elena can make 15 pizzas in 3 hours. If the number of pizzas is represented by p and time is represented by t, Write an equation that shows the total number of pizzas made in terms of time.
p = 5t
3t = 15p
p/t = 15
p = 1/5t
Answer:
p = 5t
Step-by-step explanation:
We'll check by plugging in t = 3 and p has to equal 15
p = 5t ✅
p = 5(3)
p = 15
3t = 15p ❌
3(3) = 15p
9 = 15p
p = 15/9 = 5/3
p/t = 15 ❌
p/3 = 15
p = 45
p = 1/5t ❌
p = 1/5(3)
p = 3/5

Fill in the blanks with the correct words:
An event that has probability O is said to be
An event that has probability 1 is said to be
Answer:
Impossible; certain to happen
Step-by-step explanation:
Probability = 0 applies to an event which cannot happen. Example: roll a die and get a 7.
Probability = 1 applies to an even which is certain to occur. Example: roll a die and get a number less than 8.

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
Which table shows a linear function?
Please help me with this homework
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

. If three angle of a quadrilateral are in the ratio 2: 3: 5 and fourth angle is 130
find the angles
Answer:
Step-by-step explanation:
So let the angles be 2x,3x,5x
∠A + ∠B + ∠C + ∠C = 360
[Sum of all the angles of a quadrilateral ]
⇒2x+3x+5x+130=360
⇒10x = 360 -130
⇒x = 23
The angles are ,
∠A = 2x = 2×23 = 46
∠B = 3x = 3×23 = 69
∠C = 5x = 5×23=115
Let the angles be 2x,3x and 5x
We know that 2x+3x+5x+130=360
10x+130=360
10x=230
Therefore x=23°
2x=46°
3x=69°
5x=115°

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 can be approximated by P(t)(), where t0 corresponds to .
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
