What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
Let the x values be represented as x = { 1 , 2 , 4 , 8 , 16 }
Let the y values be represented as y = { 2 , 4 , 8 , 16 , 32 }
Now , the values of y are changing over the interval as
when multiplied by 2 , we get
2 = 2 x 1
4 = 2 x 2
8 = 2 x 4
16 = 2 x 8
32 = 2 x 16
Therefore , the values are multiplied by 2
Hence , the function is y = 2x

Consider a communication source that transmits packets containing digitized speech. After each transmission, the receiver sends a message indicating whether the transmission was successful or unsuccessful. If a transmission is unsuccessful, the packet is resent. Suppose a voice packet can be transmitted a maximum of 8 times. Assuming that the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p, determine the probability mass function of the number of times a packet is transmitted.
Answer:
The probability mass function is
[tex]F(x) = [ \left \ 8 } \atop {x}} \right. ] * p^x * q^{n - x }[/tex]
Step-by-step explanation:
From the question we are told that
The maximum transmission time is [tex]n = 8[/tex]
Generally the number of times a packet is transmitted follows a binomial distribution given that the the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p
Generally the probability mass function is mathematically represented as
[tex]F(x) = [ \left \ 8 } \atop {x}} \right. ] * p^x * q^{n - x }[/tex]
Here x can take values x = 0 , 1 , 2 , 3 , ... , 7

The cost price of a refrigerator is $1850.00. A buyer who is given a discount of 5% for a cash purchase will pay
Answer:
[tex]\huge\boxed{\$1757.50}[/tex]
Step-by-step explanation:
In order to find a 5% discount off $1850, we have to realize 100% of something is the whole thing.
This means that a 5% discount makes the new cost [tex]100-5=95[/tex]% of the original.
To find 95% of a number, we can convert 95% into a decimal and multiply it by 1850.
When converting a percent to a decimal, we always divide the percent by 100.
[tex]95 \div 100 = 0.95[/tex]
We can now multiply 1850 by 0.95.
[tex]1850 \cdot 0.95 = 1757.50[/tex]
So the buyer only pats $1757.50.

Find the equation of a line that contains the points (3,1) and (5,-4). Write the equation in slope-intercept form
Answer:
y= -5x/2+17/2.... (x is between -5/2)
slope intercept= mx+b
y= -5x/2+17/2
Step-by-step explanation:
The equation of line in slope intercept form which passes through the points (3,1) and (5,-4) is [tex]-\frac{5}{2} x+\frac{17}{2}[/tex] .
What is the equation of line in slope intercept form?
The equation of line in the form of [tex]y = mx + b[/tex], is called slope intercept form of a line.
How to find equation of line from two points?The equation of line from two points is given by
[tex]y -y_{1} = \frac{y_{2} -y_{1} }{x_{2}-x_{1} } (x-x_{1} )[/tex]
According to the given question
We have two points (3,1) and (5, -4)
Therefore, the equation of line which passes through the points (3,1) and (5, -4) is given by
[tex](y -1)=\frac{-4-1}{5-3} (x-3)[/tex]
⇒[tex](y-1)=\frac{-5}{2}(x-3)[/tex]
⇒[tex]y -1=\frac{-5}{2}x+\frac{15}{2}[/tex]
⇒[tex]y =-\frac{5}{2} x+\frac{15}{2} +1[/tex]
⇒[tex]y = -\frac{5}{2}x+\frac{17}{2}[/tex]
Hence, the equation of line in slope intercept form which passes through the points (3,1) and (5,-4) is [tex]-\frac{5}{2} x+\frac{17}{2}[/tex] .

Answer:
For a given confidence level, t* is never smaller than z*.
Step-by-step explanation:
t* and z* are the critical value of a confidence interval. For example, at 95% confidence, z* = 1.96. This is because 95% of a normal curve is within ±1.96 standard deviations.
A student's t distribution has the same bell-curve shape as a normal distribution, but is shorter and wider, which is why t* is always larger than z*. As the sample size increases to infinity, the distribution approaches normal.

The Red Ravens Swim Team practices several hours a week to get ready for swim meets. They spend 3 times as many practice hours in the pool as in the weight room.If the swim team practiced 8 hours total last week, how many hours did they spend in the pool?
Answer:
the answer is 24 hope this helped
Step-by-step explanation:
If the swim team worked out for 8 hours last week, 6 of those hours were spent in the pool.
What is the ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given, In order to prepare for swim meets, the Red Ravens Swim Team practices for several hours each week. They practice in the water for three times as long as they practice in the gym.
Since the waiting time is three times as in pool times
Let "t" be the time in the pool during practice
thus, Waiting time = 3t
Also given, the swim team practiced 8 hours total last week
So,
t + 3t = 8
t = 2
Thus, time spent in the pool = 3t = 3*2 = 6
therefore, If the swim team practiced 8 hours total last week, 6 hours they spend in the pool.

The supplementary angle pairs are: angles 4 and 5
What are supplementary angles?Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles.
