A few points (co-ordinates) for the given equations are :
(1,-1/2),(-1,1/4),(0,1),,(2,-1/4)
What are the points on the graph called?These points are called Coordinates, where the horizontal line denotes the x-axis and the verticle line is the y-axis.
Each point is identified by both x and y coordinates. A point's x-coordinate is a value that indicates how far the point is from the horizontal or x-axis origin.
According to the given information:y denotes the distance of the point on the vertical line from the origin
x denotes the distance of the point on the horizontal line from the origin
In the given equation y=-1/3x-1
We can substitute x with any integer (i.e any number among the positive or negative numbers)
Putting, x=1 in the given equation we get
y=-1/(3x1)-1
⇒ y=-1/3-1
⇒y=-1/2
Thus the coordinate when x=1 is (1,-1/2)
Similarly by putting x=0, 1, 2, -1 ;we get the following co-ordinates respectively
(0,1), (1,-1/2), (2,-1/4),(-1,1/4)

The system of equations has its solutions to be (0, 3)
How to determine the solution to the system of equations?From the question, the system of equations is represented on the graph
On the graph, we have the following representations
Two lines of different colorsBoth lines intersect at a pointSay the functions are f(x) and g(x)
To determine the solution to the system of equations, we set both equations equal
i.e. f(x) = g(x)
This in other words mean that we determine the coordinates of the points where the graphs intersect
In this case, they intersect at point (0, 3)
This represents the solution
Hence, the solution to the system of equations is (0, 3)

How many bit strings are there of length eight?
There are 28 which is 256. That means there are 256 different values you can store in a byte, since a byte is eight bits. There are 256 eight-bit ASCII codes, for instance.
1 byte = 8 bits
Number of bits = [tex]2^{8}[/tex]
= 2*2*2*2*2*2*2*2
= 4*2*2*2*2*2*2
= 8*2*2*2*2*2
= 16*2*2*2*2
= 32*2*2*2
= 64*2*2
= 128*2
= 256 bits.
Therefore that means there are 256 different values you can store in a byte, since a byte is eight bits.

A telephone exchange operator assumes that 8% of the phone calls are wrong numbers.
If the operator is correct, what is the probability that the proportion of wrong numbers in a sample of 494 phone calls would differ from the population proportion by more than 3%? Round your answer to four decimal places.
The probability that the phone calls would differ from the population proportion by more than 3% is 0
How to determine the probability value?From the question, the given parameters about the distribution are
Proportion, p = 8%Sample size, n = 494The actual proportion, x = greater than 3%The mean is calculated as
Mean = np
So, we have
Mean = 8% * 494 = 39.52
The standard deviation is calculated as
Standard deviation = √np(1 - p)
So, we have
Standard deviation = √494 * 8% (1 - 8%) = 0.77
The z-score is calculated using the following formula
[tex]z = \frac{\bar p - p}{\sqrt{p(1 - p)}/n}[/tex]
Substitute the given parameters in the above equation
[tex]z = \frac{8\% - 3\%}{\sqrt{8\% * (1 - 8\%)}/494}[/tex]
Evaluate
z = 90.9
The probability is then calculated as:
P(x > 3%) = P(z > 90.9)
From the z table of probabilities, we have;
P(x > 3%) = 0
Hence, the probability is 0

Which function is positive for the entire interval [–3, –2]?
Graph 2 represents that the function is positive for the entire interval [-3,-2].
What is a function?Every possible input value results in exactly one output value in a function. "The output is a function of the input," we state. The domain is made up of the input values, while the range is made up of the output values.
Four different graphs for various functions are provided. We must identify the graph that is positive throughout the range [-3,-2].
We make the following observation from the given graphs.
1. The function in graph 1 has a value of 0 at -3 and decreases in value from -3 to -2. As a result, in the provided interval, the function is negative.
2. Graph 2 makes it abundantly evident that the function has a positive value for the entire specified interval.
3. In graph 3, the function shows a negative value entirely in the given interval.
4. In graph 4, the function exhibits both positive and negative values in the given interval and is not positive in the entire interval.
Thus, the function in graph 2 is positive for the entire interval [-3,-2].

The linear function that is graphed on the grid is g(x) = (15/2)x + 45 , the correct option is (d) .
In the question ,
a linear function graph is shown ,
we have to find that linear function .
So , From the given graph we can see that
the graph passes from the points (2 , 60) and (6 , 90)
in order to find the equation , we first need to find the slope .
slope = (90 - 60)/(6 - 2)
= 30/4
= 15/2
So , the equation of the line passing through the points (2 , 60) and slope 15/2 is
(y - 60) = 15/2(x - 2)
y - 60 = (15/2)x - 15
Adding 60 to both the sides ,
we get
y - 60 + 60 = (15/2)x - 15 + 60
y = (15/2)x - 15 + 60
y = (15/2)x + 45
function is (15/2)x + 45
Therefore , The linear function that is graphed on the grid is g(x) = (15/2)x + 45 .

find the equation of a line parallel to 3x +2y=14 that passes through the point (8,8)
The equation of the parallel line is y = (-3/2)x + 20
What does the term Slope of a Straight Line means?
A line's slope is defined as the change in y coordinate with respect to the change in x coordinate. The net y coordinate change is y, while the net x coordinate change is x.
Solution:
Firstly we need to find the slope of the given line 3x+2y = 14
Since, the equation is in the form ax + by = c
Therefore, by comparing we can say a = 3 and b = 2
Slope = -(b/a) = -3/2
Since we need to find the equation of the parallel line
So, the slope of the parallel line will be -3/2
y = mx + b
we know that the line passes through the point (8,8)
putting x,y = 8 and m = -3/2
8 = (-3/2)*8 + b
8 = -12 + b
b = 20
So, the equation of the parallel line is y = (-3/2)x + 20

The evaluated expression of (6x+3y) - z² divide by 2x when x = -3, y = 4 and z = -6 is 5.3
How to evaluate an expression?An algebraic expression consists of unknown variables, numbers and arithmetic operators.
Therefore, let's evaluate the expression, (6x+3y) - z² divide by 2x when x = -3, y = 4 and z = -6.
To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number.
In other words, to evaluate the expression, we have to substitute the given value of the variable and simplify the expression.
Therefore,
(6x+3y) - z² = (6(-3)+3(4)) - (-6)² = (-18 + 12) - 36 = -32
2x = 2(-3) = -6

The lower and upper limit of the 95% confidence interval is 183.2 and 196.0 unit.
What is a confidence interval ?
When you run your experiment again or resample the population in the same way, you can expect your estimate to fall within a certain range of values a certain percentage of the time. This is known as the confidence interval.
Main Body:
Given in question :
x- bar = 189.6
standard deviation = 10
C.I. = 95% =0.95
N=12
so, degree of freedom (D.F) = N-1 = 11
confidence level (α) = (1- C.I.)/2
= 0.025
according to t- distribution table for d.f = 11 and α= 0.025 , my result is 2.201
Now dividing standard deviation by square root of samples, we get
= 10/√12= 2.887
Lower limit = Mean - 2.201*2.887
= 189.6- 6.354
= 183.246
Upper limit = Mean + 2.201*2.887

the dimensions of a rectangle are 5x-7 and 2x-1. what is the perimeter?
please help fast!
The formula for the perimeter of the rectangle is:
P(x) = 14x - 16
What is the perimeter?We know that for a rectangle of length L and width W the perimeter is given by the formula:
P = 2*(W + L)
In this case we know that:
W = 2x - 1
L = 5x - 7
Replacing that in the perimeter formula we get:
P(x) = 2*(2x - 1 + 5x - 7)
Now we can simplify this so we get:
P(x) = 2*(2x + 5x - 1 - 7)
P(x) = 2*(7x - 8)
P(x) = 14x - 16
