The decision rule for is to reject null if critical value is higher than the test statistic, since there is insufficient evidence to show that the machines are underfilling the bag.
How to carry out the hypothesis testFirst we have to solve for the test statistic
t = x - u / s /√n
the variables are stated as:
where x = 444
u = 447
n = 24
s = 10
we would have the test statistic solved as :
444 - 447 / 10 / √24
-3 / 2.0412
= -1.4697
at 0.1 significance level, we would have:
degree of freedom
n - 1
= 24 - 1 = 23
the critical value is -1.3194.
Because the critical value is greater than the test statistic, we are going to reject the null.

1. A force of 50 N acts on an object of mass 250 kg which is initially at rest, for 10 s. find the distance travelled and the velocity gained at the end of this time.
The distance travelled is 10 m
The velocity gained at the end of the time is 2 m/s
MotionFrom the question, we are to determine distance travelled and the velocity gained
From one of the equations of motion for linear motion, we have that
S = ut + 1/2at²
Where S is the distance
u is the initial velocity
t is the time taken
and a is the acceleration
First, we will calculate the acceleration
Using the formula,
F = ma
Where F is the force
m is the mass
and a is the acceleration
∴ a = F/m
Where F is the force
and a is the acceleration
From the given information,
F = 50 N
m = 250 kg
Putting the parameters into the equation,
a = 50/250
a = 0.2 m/s²
Thus,
From the information,
u = 0 m/s (Since the object was initially at rest)
t = 10 s
S = 0(t) + 1/2(0.2)(10)²
S = 10 m
Hence, the distance travelled is 10 m
For the velocity
Using the formula,
v = u + at
Where v is the velocity
v = 0 + 0.2×10
v = 2 m/s
Hence, the velocity gained at the end of the time is 2 m/s

Give the equation of the circle that has a diameter with endpoints G(-6, — 3) and
R(-6,-8).
Generally, the equation of a circle is organized like this: [tex](x-h)^2+(y-k)^2=r^2[/tex], where (h,k) is the centre and r is the radius.
Solving the QuestionWe're given the endpoints of the diameter: [tex](-6,-3)[/tex] and [tex](-6,-8)[/tex].
First, we can find the centre of the circle by finding the midpoint of these two endpoints.
[tex]midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
Plug in the points:
[tex]midpoint=(\dfrac{-6+-6}{2},\dfrac{-3+-8}{2})\\\\midpoint=(-6,\dfrac{-11}{2})[/tex]
Therefore, the centre of the circle is [tex](-6,\dfrac{-11}{2})[/tex]. Plug this into the general equation:
[tex](x-h)^2+(y-k)^2=r^2\\\\(x-(-6))^2+(y-(-\dfrac{11}{2}))^2=r^2\\\\(x+6)^2+(y+\dfrac{11}{2})^2=r^2[/tex]
To find the radius of the circle, we can calculate the distance between the centre and one of the given endpoints:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Plug in the centre and one of the endpoints:
[tex]d=\sqrt{(-6-x_1)^2+(\dfrac{-11}{2}-y_1)^2}\\d=\sqrt{(-6-(-6))^2+(\dfrac{-11}{2}-(-3))^2}\\d=\sqrt{(-6+6)^2+(\dfrac{-11}{2}+3)^2}\\\\d=\sqrt{(0)^2+(-5.5+3)^2}\\\\d=\sqrt{(0)^2+(-2.5)^2}\\\\d=\sqrt{(0)^2+(-\dfrac{5}{2})^2}\\\\d=\sqrt{0+\dfrac{25}{4}}\\d=\sqrt{\dfrac{25}{4}}\\\\d=\dfrac{5}{2}[/tex]
Therefore, the radius of the circle is [tex]\dfrac{5}{2}[/tex]. Plug this into the general equation:
[tex](x+6)^2+(y+\dfrac{11}{2})^2=r^2\\\\(x+6)^2+(y+\dfrac{11}{2})^2=(\dfrac{5}{2})^2\\\\(x+6)^2+(y+\dfrac{11}{2})^2=\dfrac{25}{4}[/tex]

What is a confidence interval?The likelihood that a parameter will fall between two values near the mean is shown by a confidence interval.
Confidence intervals quantify how certain or uncertain a sampling technique is.
Confidence intervals are used by statisticians to gauge the degree of uncertainty in a sample variable.
The 90% confidence interval is given by:
Mean - 1.645(S.D./[tex]\sqrt{n}[/tex]) < μ < Mean + 1.645(S.D./[tex]\sqrt{n}[/tex])
2μ = 5.22 + 5.98 = 11.2
μ = 11.2 / 2 = 5.6
Thus,
5.6 - 5.22 = 1.645(S.D./[tex]\sqrt{n}[/tex]) = 0.38
S.D./[tex]\sqrt{n}[/tex] = 0.38 / 1.645 = 0.231

solve using substitution:
4x- 2y = 6 and x + y = 6
solve using elimination:
4x- 2y = 6 and x + y = 6
Answer:
Step-by-step explanation:
Substitution is a method that rewrites one of the equations in terms of one variable, and substitutes that in the other equations.
We can easily rewrite x + y = 6 by subtracting y from both sides, giving us
[tex]x = -y+6[/tex]
By putting this equation in place of x in the first equation, we can solve for y:
[tex]4(-y+6)-2y=6[/tex]
[tex]-4y+24-2y=6[/tex] [Distributing 4 into the parentheses]
[tex]-6y+24=6[/tex] [Combining like terms]
[tex]-6y = -18[/tex] [Subtracting 24 from both sides]
[tex]y=3[/tex] [Dividing both sides by -6]
Since we solved for y, we can again substitute by putting it into the second equation.
[tex]x+3=6[/tex]
[tex]x=3[/tex] [Subtracting 3 from both sides]
The solution for this system of equations is (3,3).
Elimination is another method of solving systems of equations. In this method, we multiply one equation such that when both equations are combined, only one variable is left.
We can first multiply both sides of the second equation by 2.
[tex]2x+2y=12[/tex]
Now, let's add both equations to cancel out y.
[tex]4x-2y=6[/tex]
[tex]2x+2y=12[/tex]
[tex]6x=18[/tex]
Now, we can divide 6 from both sides to get the value of x.
[tex]\frac{6x}{6} = \frac{18}{6}[/tex]
[tex]x=3[/tex]
We can now substitute this value into one of the equations to get the value of y. Here, I used the second equation.
[tex]3+y=6[/tex]
[tex]y=3[/tex]
The solution to our system of equations is (3,3).
Pentagon ABCDE and pentagon A″B″C″D″E″ are shown on the coordinate plane below:
Which two transformations are applied to pentagon ABCDE to create A″B″C″D″E″?
The transformations that are applied to pentagon ABCDE to create A"B"C"D"E" are:
1) Translation (x, y) → (x + 8, y + 2)
2) Reflection across the x-axis (x, y) → (x, -y)
So, the overall transformation given in the graph is (x, y) → {(x + 8), -(y + 2)}.
What are the transformation rules?The transformation rules are:
Reflection across x-axis: (x, y) → (x, -y)Reflection across y-axis: (x, y) → (-x, y)Translation: (x, y) → (x + a, y + b)Dilation: (x, y) → (kx, ky)Calculation:The pentagons in the graph have vertices as
For the pentagon ABCDE: A(-4, 5), B(-6, 4), C(-5, 1), D(-2, 2), and (-2, 4)
For the pentagon A"B"C"D"E": A"(4, -7), B"(2, -6), C"(3, -3), D"(6, -4), and E"(6, -6)
Consider the vertices A(-4, 5) from the pentagon ABCDE and A"(4, -7) from the pentagon A"B"C"D"E".
Applying the Translation rule for the pentagon ABCDE:
The rule is (x, y) → (x + a, y + b)
So, the variation is
-4 + a = 4
⇒ a = 4 + 4 = 8
5 + b = 7
⇒ b = 7 - 5 = 2
So, the pentagon ABCDE is translated by (x + 8, y + 2).
Applying the Reflection rule for the translated pentagon:
The translated pentagon has vertices (x + 8, y + 2).
When applying the reflection across the x-axis,
(x + 8, y + 2) → {(x + 8), -(y + 2)}
Therefore, the complete transformation of the pentagon ABCDE to the pentagon A"B"C"D"E" is (x, y) → {(x + 8), -(y + 2)}
Verification:
A(-4, 5) → ((-4 + 8), -(5 + 2)) = (4, -7)A"
B(-6, 4) → ((-6 + 8), -(4 + 2)) = (2, -6)B"
C(-5, 1) → ((-5 + 8), -(1 + 2)) = (3, -3)C"
D(-2, 2) → ((-2 + 8), -(2 + 2)) = (6, -4)D"

Circles that overlap have a commonality while circles that do not overlap do not share those traits. Venn diagrams help to visually represent the similarities and differences between two concepts
Step-by-step explanation:
Answer:
uses overlapping circles or other shapes to illustrate the logical relationships between two or more sets of items
Step-by-step explanation:
looks like circles that meet and overlap and
the middle part explains the relationship of both circles
example
if the left circle says water & right circle says freezing the middle part would say ice

Why is it important to be able to express a clear and coherent argument visually or in writing? Think: where would you use this in the “real-world?”
It is important to be able to express a clear and coherent argument visually or in writing because without establishing coherence, your reader will not be able to know or understand the key points that you are trying to express or show.
Why is it important to have coherence in one's writing?Coherence is known to be a key quality for kind of good academic write up.
Note that in the area of academic writing, the ways that ideas flows is very important and as such, it need to be smooth and logical.
Therefore without coherent argument , the reader cannot understand the key points that a person is trying to show and thus hinders the readability of your work.

The Drury Lane Theater has 10 seats in the first row and 38 rows in all. Each successive row contains one additional seat. How many seats are in the theater?
[tex]{anyone \: is \: here \: }[/tex]
Answer:
1083 seats
Step-by-step explanation:
i just answered that.
arithmetic sequence
a1 = 10
an = an-1 + 1 = a1 + (n-1)×1 = 10 + (n-1) = 9 + n
a38 = 9 + 38 = 47 seats
the sum of such an arithmetic sequence
n×(a1 + an)/2
in our case
38×(10 + 47)/2 = 19×57 = 1083 seats
There are 4 reb balls, 6 white balls, and 3 green balls in a bag. If one ball is drawn the bag at random, what is the probability that it is not white?
Answer:
7/13
Step-by-step explanation:
in all there are 13 balls and the number of balls that aren't white are 7
Answer:
7/13
Step-by-step explanation:
To find the probability that it is not white
P( not white) = number of balls that are not white / total balls
The balls that are not white are red and green = 4+3
= (4+3)/ ( 4+6+3)
= 7/13

Two sets of data both have a mean of 76. however, the first set has a standard deviation of 1.4 and the second set has a standard deviation of 5.7. what must be true about the two sets?
1) it is not possible to have two sets with the same mean and different standard deviations.
2) the first set of data has values that are closer to the mean because the standard deviation is lower.
3) the first set of data has values that are farther from the mean because the standard deviation is lower.
4) the second set has more data values than the first.
Option 2) the first set of data has values that are closer to the mean because the standard deviation is lower is correct
If two samples have the same mean, then it means that the two values in the two samples are centered around the same value. However, this does not mean that the data values in the samples vary equally around this center and thus the standard deviations may also differ.
It depends what the standard deviations are. The standard deviation is a measure of how close the results are to the mean, a low standard deviation means that the measurements are accurate, so close to the mean. A high standard deviation means that the measurements are more spread out.
We need to find that if two sets of data both have a mean of 76. however, the first set has a standard deviation of 1.4 and the second set has a standard deviation of 5.7. what must be true about the two sets
The first set of data has values that are closer to the mean because the standard deviation is lower because in first set standard deviation is 1.4 and in second set standard deviation is 5.7
The one with smaller standard deviation are least spead from the mean
Hence the first set of data has values that are closer to the mean because the standard deviation is lower.

What is the length of a diagonal of a rectangle with a length of 8 meters and a width of 6 meters
Answer:
10 m
Step-by-step explanation:
If we draw the diagonal of the rectangle, we form a right triangle where the diagonal is the hypotenuse and the legs are 6 and 8.
This is a well-known Pythagorean triple, which gives the diagonal to be 10 m.
