Which table of ordered pairs matches the following function?
2y + 8x = 2
Answers
step-by-step explanation:
i don’t understand what you’re trying to ask so i’ll just tell you everything about this function
2y + 8x = 2
y = 0
2(0) + 8x = 2
8x = 2
/8 /8
x = 1/4
x = 0
2y + 8(0) = 2
2y = 2
/2 /2
y = 1
1 is the y-intercept and 1/4 is the x-intercept
it is a straight line downwards
the function would be
2y + 8x = 2
-8x -8x
2y = -8x + 2
/2 /2 /2
y = -4x + 1
-4x is the slope 1 is the y-intercept
the graph would look like this

The image of the hexagon is missing, so i have attached it.
Answer:
∠1 = 36°
Step-by-step explanation:
From the image attached, we can see that the polygon is regular and has 10 sides.
Formula for an interior angle of a regular polygon is;
θ = 180(n - 2)/n
Where n is the number of sides of the polygon.
Thus;
θ = 180(10 - 2)/10
θ = 144°
Now, ∠1 forms a straight line with one of the interior angles of the polygon.
Thus, θ + ∠1 will be equal to 180° because sum of angle on a straight line is 180°
Thus;
144° + ∠1 = 180°
∠1 = 180° - 144°
∠1 = 36°

Answers
Answer:
5/2
Step-by-step explanation:
We first find the equation of the line. The slope-intercept form of a line is y = mx + b, where b is the y-intercept and m is the slope. We already know the y-intercept, which is (0,5). Therefore, our current equation is:
y = mx + 5.
We use (0,5) and (1,3) to find the slope. We subtract the two y-coordinates, 5 - 3 = 2. We subtract the x-coordinates, 0 - 1 = - 1. The slope is given as rise/run, which is (y-coordinate difference)/(x-coordinate difference. Thus, the slope is 2/-1, which is just -2. Now, we put -2 in place of m:
y = -2x + 5.
The x-intercept is when the y-coordinate is equal to 0. So we substitute 0 for y:
0 = -2x + 5
-5 = -2x
x = 5/2
The manager of a fast food restaurant is supposed to serve coffee that is 160 degrees Fahrenheit. A random sample of 20 cups of coffee reveal that the mean temperature is 151 degrees Fahrenheit with a standard deviation of 3 degrees. The manager would like to conduct a t-test for the population mean temperature of all cups of coffee served at this restaurant. Are the conditions for inference met?
No, the random condition is not met.
No, the 10% condition is not met.
No, the Normal/large sample condition is not met.
Yes, all conditions for inference are met.
Answers
Answer:
C. No, the Normal/large sample condition is not met.
Step-by-step explanation:
There is only 20 cup and for a sample to meet the Normal/large sample condition it must be greater than 30 samples or have a normal distribution or have no skewness or outliers
No, the Normal/large sample condition is not met.
Option C is the correct answer.
What is a t-test?A t-test is a statistical test used to determine whether there is a significant difference between the means of two groups or samples.
It is used when the sample size is small or the population standard deviation is unknown.
We have,
The conditions for inference in a t-test are:
Random condition:
The sample should be selected randomly from the population to ensure that the sample is representative of the population.
Normal/large sample condition:
The population should be normally distributed, or the sample size should be large enough to assume normality. A commonly used rule of thumb is that the sample size should be at least 30.
Independence condition:
The observations in the sample should be independent of each other.
In this case,
The random condition is met as the sample was selected randomly. However, the normal/large sample condition is not met since the sample size is only 20, and it's not clear if the population of coffee temperatures is normally distributed.
Therefore, the conditions for inference are not met, and a t-test for the population mean temperature of all cups of coffee served at this restaurant cannot be conducted.
Thus,
No, the Normal/large sample condition is not met.

First, put the values in order from least to greatest.
2, 18, 3, 2, 9, 17, 41, 22, 25, 27, 17, 5, 4 becomes
2, 2, 3, 4, 5, 9, 17, 17, 18, 22, 25, 27, 41
The mean is the sum of all the values divided by the number of values.
2 + 2 + 3 + 4 + 5 + 9 + 17 + 17 + 18 + 22 + 25 + 27 + 41 = 192. 192/13 = 14.7692308, which rounds to 14.8
The median is the number in the middle, which is 17.
The mode is 2 AND 17, because those are the numbers that appear most often.
Range is the maximum value minus the minimum value. 41 - 2 = 39 so that is the range.
Upper quartile is the median of all the numbers to the right of 17. Median of 17, 18, 22, 25, 27, 41 is 23.5 because it is the mean of the 2 numbers in the middle.
Lower quartile is the median of all the numbers to the left of 17. Median of 2, 2, 2, 3, 4, 5, 9 is 3.5 because it is the mean of the 2 numbers in the middle.

Answers
Answer:
[tex]6.3m/s[/tex]
Step-by-step explanation:
Note: We will take g as 9.8 in this question.
The two equations we will use for this questions are:
[tex]G.P.E = mgh[/tex], m = mass, g = acceleration due to gravity
and the SUVAT equation: [tex]v^2=u^2+2as[/tex]
First, let's start out by finding the height from which the object is being dropped. We can do this by using the gravitational potential energy formula.
Subbing the values we have:
[tex]50 = 2.5*9.8*h[/tex]
[tex]h = 2.04[/tex] - re-arranging for the height we get a height of 2.04.
Now we will use the SUVAT equation. Let's set out the variables we have:
[tex]S=2.04\\U=0\\V=?\\A=9.8\\T=N/A[/tex]
U (initial speed) is equal to 0 because we are dropping the object from rest. Acceleration is equal to 9.8 as that is the acceleration due to gravity. The displacement (S) is the height we just worked out.
Now let's put them into one of the SUVAT equations:
[tex]v^2=u^2+2as[/tex]
[tex]v^2=(0)^2+2(9.8)(2.04)[/tex]
[tex]v^2=39.984[/tex]
[tex]v=6.3 m/s[/tex]
In Texas the state sales

machine at $420.00
and a dryer for
$360.00
How much will Beth's total be
including state sales tax
Answers
Answer: $826.8
Step-by-step explanation:
First, we add the amount of money that the machines sold for:
$420 + $360 = $780
Next, we multiply it by the sales tax, 6%,
$780 x 6%(0.06) = $46.80
Finally, we add this to the total:
$780 + $46.80 = $826.80
Alternatively, you can add the total sales and multiply by 106% using the 2-step method.

There is a positive linear association between the number of hits and the

The point at (7, 13) is an outlier because it is the only game for which the
