For each event, write the sample space and tell how many outcomes there are. Roll a standard number cube. Then flip a quarter. How many outcomes are there?
The total number of outcomes is 12.
An outcome is a potential outcome of an experiment or trial in probability theory.
Each conceivable result of a specific experiment is distinct, and many results are incompatible (only one outcome will occur on each trial of the experiment). The components of a sample space are all the potential results of an experiment. There is a chance that outcomes will occur with probabilities between 0 and 1. (inclusively). In a discrete probability distribution whose sample space is finite, each result is assigned a certain probability. A continuous distribution, on the other hand, only allows non-zero probabilities to be assigned to ranges of events, with all individual outcomes having zero probability.When a number cube is rolled there are 6 distinct outcomes {1,2,3,4,5,6} = 6
Again when a quarter is flipped then there are two possible outcomes {heads , tails } = 2
The total number of outcomes = 6 × 2 = 12
Hence there are 12 distinct outcomes.

Consider this function f(x) = x -4
The inverse of the given function is f-1(x)= x²+4.
What is inverse of a function?A function that "undoes" another function in mathematics is known as an inverse. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f-1.
To calculate the inverse of a function:
Consider f(x)=y
And interchange the variables.
So given f(x)= √x-4 becomes
y=√x-4 ⇒ x=√y-4
Now on squaring both sides we get,
x²= y-4
⇒ y = x²+4
Replace y by f-1(x)
So the equation becomes,
f-1(x) = x²+4

State the degree and end behavior of f(x)=8x³+2x⁴-5x²+9. Explain or show your reasoning.
Examining the given polynomial we arrive at the various parameters
the polynomial is degree 4The end behavior is x → ∞ f(x) → ∞, x → - ∞ f(x) → ∞How to find the degree of a polynomialThe degree refers to the maximum power to which the equation is raised. We can see that the term 2x⁴ bears the maximum power and it is 4 hence the equation is degree 4
How to find the end behavior of a polynomialThe end behavior refers to how the equation relates at the extremes. The extremes a big positive value and big negative value.
Big positive value say x = 1000
f(x)=8x³+2x⁴-5x²+9
f(1000) = 2.008x10^12
Big negative value say x = -1000
f(x)=8x³+2x⁴-5x²+9
f(-1000) = 1.992x10^12
comparing the two values shows that the value is increasing in both positive and negative, hence we write the end behavior as x → ∞ f(x) → ∞, x → - ∞ f(x) → ∞

Find the length of the segment indicated. Round your answer to the nearest tenth if necessary.
The answer is 16.4
Answer:
x = 16.4
Step-by-step explanation:
From the diagram, we can see that the radius of the circle is 19.4 as the line labelled 19.4 goes from the centre to the edge of the circle.
Therefore the length of the line marked in green is also 19.4 units, as it is also a radius of the circle.
Now we can simply use the Pythagorean Theorem to calculate the value of [tex]x[/tex]:
[tex]19.4^2 = x^2 + 10.3^2[/tex]
⇒ [tex]x^2 = 19.4^2 - 10.3^2[/tex]
⇒ [tex]x = \sqrt{19.4^2 - 10.3^2}[/tex]
⇒ [tex]x = \bf 16.4[/tex]
Therefore the length of the indicated segment is 16.4 units.

Jesse and amir were assigned the same book to read. jesse started reading on saturday, and he is reading 30 pages a day. amir didn't start until sunday, but he is reading 35 pages a day.
He will read 210 pages of the book and it will take Amir 6 days to catch up with Jesse
Day Jesse started reading: Saturday
Number of pages read by Jesse each day: 30 pages
Day Amir started reading: Sunday
Number of pages read by Amir each day: 35 pages
Let x represent the number of days Amir has been reading and y represent the number of pages he has read
Formulating the equation for Amir we get:
y = 35*x
y = 35x
The equation for Jesse will be:
y = 30*(x+1)
y = 30(x+1)
Equating both equations we get:
35x = 30(x+1)
35x = 30x +30
5x = 30
x=6
So, the number of pages read will be 210 and it will take 6 days for Amir to catch up with Jesse

A large container is being filled with water at the rate of 2 3/4 per minute
Answer:
5 minutes and 20 seconds
Step-by-step explanation:
basically your equation is: (rate of filling container) x (time to fill container)
- (minus)
(rate of leaking from container) x (time to fill container)
=
(the size of the container in gallons)
--------------------
step 1 - so t = the time in minutes to fill14 gallon container
step 2 - convert 2 3/4 to quarters so:
2 • 4 = 8 and it’s in quarters so 8/4 then
8/4 + remaining 3/4 = 11/4
step 3 - so then you fill in the equation:(11/4)•t - (1/8)•t = 14
step 4 - multiply both sides of the equation by 8:
(11/4) = 2.75 • 8 = 22
(1/8) = 0.125 • 8 = 114 • 8 = 112
so the equation is:
22t - t = 112
step 5 - divide both sides of the equation by 22:
22t / 22 = t
112 / 22 = 5.333
so t = 5.333
step 6 - convert
so 5.333 has a repeating decimal of 0.3 which is 1/3. so to convert that to seconds, take 1/3 of 60:
60 / 3 = 20
so it takes 5 minutes and 20 seconds to fill the 14 gallon container

a gigabyte of computer storage space is 2^30 bytes.A computer has a total storage space of 128 gigabytes.How many bytes of total storage space does the computer have?Write your answer as a power.
There are 2 ³⁷ bytes in 128 gigabytes.
Bytes, which typically contain eight bits, are the basic building blocks of digital information.
Because previously a single character of∀⊅ text required only a certain number of bits to be encoded in a computer, the byte is the lowest addressable unit of memory in all computer systems. To distinguish them from the standard 8-bit definition, network protocol documents like The Internet Protocol (RFC 791) refer to an 8-bit byte as an octet. An octet's bits are commonly counted from 0 to 7 or 7 to 0, depending on the bit endianness. The eighth bit is a seven since the first bit is a zero.We know that 128 = 2⁷
Now each gigabyte = 2³⁰ bytes
So the total number of bytes in 128 gb is
2⁷ × 2³⁰ = 2³⁰⁺⁷ = 2 ³⁷
Therefore there are 2³⁷ bytes in 128 gigabytes.
