Answer:
Some functions do not have inverse functions. ... If f had an inverse, then its graph would be the reflection of the graph of f about the line y = x. The graph of f and its reflection about y = x are drawn below. Note that the reflected graph does not pass the vertical line test, so it is not the graph of a function.
Cindy throws one red and one blue regular (six-sided) fair dice. Find the probability that the sum of the two dice is greater than 2.
a 1/36
b 35/36
c 33/36
d 1
Answer:
5/36 is your answer.
Step-by-step explanation:
If the red die shows a "2", then the blue die must take on the values from the set {2,3, 4, 5, 6} in order for the sum of both dice to be larger than 4.
1+2=3
2+3 = 5
2+4 = 6
2+5 = 7
2+6 = 8
There are 6*6 = 36 total ways to roll two dice and exactly 5 ways to get the conditions stated above. The probability of getting a sum greater than 2 is 5/36
The probability that the sum of the two dice is greater than 2 will be 35/36. Then the correct option is B.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
Cindy throws one red and one blue regular (six-sided) fair dice. The total number of events will be
Total events = 6 x 6 = 36
The probability that the sum of the two dice is greater than 2 will be given as
P = 1 - 1 / 36
P = 35 / 36
The probability that the sum of the two dice is greater than 2 will be 35/36. Then the correct option is B.

What is the value of x? *
3x + 10=3x - 28
Answer:
x = 27
Step-by-step explanation:
First of all the equation written on the question is incorrect, like not the image, this is because the angle of 3x + 10 and 3x - 28 is not the same, The equation will be 3x + 10 + 3x - 28 = 180
=> 6x - 18 = 180
=> 6x = 180 - 18
=> 6x = 162
=> x = 162 / 6
=> x = 27

ishwar can read 5 pages in 15 minutes. Anne can read 15 pages in 1 hour. Explain how much longer it would take Anne to read a 300- page book than Ishwar.
Answer: 5 hours
Step-by-step explanation:
Ishwar's speed per hour:
Number of 15 minute periods in an hour:
= 60 /15
= 4 periods
Ishwar reads at 5 pages in 15 minutes so in an hour Ishwar would read:
= 4 * 5
= 20 pages per hour
Annie = 15 pages in an hour.
Ishwar number of hours to read 300 pages:
= 300 / 20
= 15 hours
Annie number of hours to read 300 pages:
= 300 / 15
= 20 hours
Difference = 20 - 15
= 5 hours

det = x * x - 4 * 3 = x^2 - 12
x^2 - 12 = 13

Why is the Remainder Theorem used to determine whether a linear binomial is a factor of a polynomial?
Answer:
This is because it helps us factorize the polynomial more easily.
Step-by-step explanation:
The remainder theorem which states that if P(x) is a polynomial and x - a is a linear factor, then the remainder when P(x) is divided by x - a is P(a). When P(a) = 0, then x - a is a factor of P(x).
So, the remainder theorem is used to determine whether a linear binomial is a factor of a polynomial because it helps us factorize the polynomial more easily.
When the polynomial is divided by the linear factor, we obtain a polynomial of lesser degree which can then be further factorized to obtain all the factors of our initial polynomial.
The remainder theorem is used to determine the factors of a polynomial, and also to determine the remainder of a polynomial when it is divided by a linear binomial
A linear binomial is represented as:
[tex]\mathbf{f(x) = mx \pm c}[/tex]
Where n and x are both constants
A polynomial is represented as:
[tex]\mathbf{P(x) = ax^n +......+d}[/tex]
Assume the linear binomial is:
[tex]\mathbf{f(x) = x - c}[/tex]
If f(x) is a factor of P(x), then by the remainder theorem, the following must be true
[tex]\mathbf{P(c) = 0}[/tex]
This is so, because it allows factorization to be done with ease.
However, if [tex]\mathbf{P(c) \ne 0}[/tex]
Then, f(x) is not a factor of P(x)

The Weston family spends a maximum of
$50.00 per month on entertainment. Write and
graph an inequality to represent this.
Answer:
y < 50x
Step-by-step explanation:
In order to graph this inequality, you first need to identify the important word(s) here to find the inequality sign; in this case, it would be "maximum of $50" a month. Since it's a maximum of $50 a month (or less than $50 a month), you can write it as:
Where m is months and c is total cost, c < 50m
If you need to graph this, you can write it as y < 50x. The cost is y since it's the output, and months is x since that's the input.

Suppose the average automobile insurance claim for the population is $4,560 with standard deviation of $600. What is the percentage of probability that a sample of 100 claim files will yield an average claim of $4,500 or less?
Answer:
0.15866
Step-by-step explanation:
Given that :
Population mean = μ = 4560
Standard deviation, σ = 600
Sample size, n = 100
Using the relation :
(x - μ) ÷ σ/sqrt(n)
P(x ≤ 4500) :
(4500 - 4560) ÷ 600/sqrt(100)
P(x ≤ 4500) = -60 / (600/10)
P(x ≤ 4500) = - 60 / 60
P(x ≤ 4500) = - 1
P(Z ≤ - 1) :
Using the Z probability calculator ;
P(Z ≤ - 1) = 0.15866
Hence, P(x ≤ 4500) = 0.15866

y=x^2 is the green line which is a thin "u" like shape. its going up the y axis.

~AH1807−5x−5y= −30 10x+3y= −3
Answer:
x = -3, y = 9
Step-by-step explanation:
-5x - 5y = -30
x - y = 6
x = -y + 6
10x + 3y = -3
10(-y + 6) + 3y = -3 (plug in x from the previous equation)
60 - 10y + 3y = -3
60 - 7y = -3
-7y = -63
y = 9
x = -y + 6
x = -(9) + 6
x = -3

Each of three friends flips a coin 70 times. The results for each friend are shown in the tables. Find the relative frequency for the event "heads" for each friend. If the friends combine their results to get 116 heads and 94 tails, what is the relative frequency for the event "heads"? Use pencil and paper. Suppose each friend flips a coin 700 times. Is there a value you would expect the relative frequency for the event "heads" to be close to?
Answer:
Find the relative frequency for the event "heads" for each friend:
Friend 1: 0.59 (41/70)
Friend 2: 0.7 (49/70)
Friend 3: 0.37 (26/70)
If the friends combine their results to get 116 heads and 94 tails, what is the relative frequency for the event "heads"?
0.55 (116/210)
Suppose each friend flips a coin 700 times. Is there a value you would expect the relative frequency for the event "heads" to be close to?
For Friend 1, basing it off the 0.59 frequency from earlier, I would expect the heads to be around 413.
Friend 2, 490
Friend 3, 259

3x - 23 = 28 (This is our equation)

Find the area of the figure.
Answer and Step-by-step explanation:
For this shape, we have to draw a line that goes through the point that is inside of the shape from top to bottom.
This creates a square and two triangles.
The area formula for a triangle is A = [tex]\frac{bh}{2}[/tex]
The area of a square is A = b*b
Half of 3 is 1.5.
Triangles (Area combined):
Since there are two triangles that are the same, we only need to find the area of of 1 triangle, and not divide by 2.
A = 3 × 1.5 = 4.5
Square:
A = 3 × 3 = 9
Now, we add them together to get the total area of the figure.
9 + 4.5 = 13.5
The area of the figure is 13.5 [tex]in^{2}[/tex].

Did you mean: The manager of a youth soccer team bought 50 packages of socks for $10. Each. He estimated the total cost to be $5000. Create an equation that shows how many times more the manager's estimate, e, was than the actual cost, a.
Answer:
Estimated cost is 10 times more than the actual cost
Step-by-step explanation:
Packages of socks purchased = 50
Price per package = $10
Actual cost = total package purchased * price per package
Actual cost , a = 50 * $10 = $500
Estimated cost, e = $5000
Estimated costs / actual cost
$5000 / $500
= 10
Estimated cost is 10 times the actual cost
