Answer:
The answer is A.
If you look at the x values of the coordinates, you can see that they multiply by 2 when dilated to the next shape.
M (5,0) ---> M' (10,0) 5 to 10 means a scale factor of 2. So A is your answer.
Find the coordinates of point M, that partitions the directed line segment SY from S(4,2) to Y(-4,-6) in a ratio of 1/3.
Answer:
the coordinates of point M = (2,0)
Step-by-step explanation:
Given;
point S along the segment, = S(4,2)
point Y along the segment, = Y(-4, -6)
ratio of the partition = ¹/₃
total ratio = 1 + 3 = 4
The midpoint of segment SY is calculated as follows;
[tex]mid-point (o) = \frac{x_1 + x_2}{2} ,\ \frac{y_1 + y_2}{2}\\\\ mid-point (o) = \frac{4 + (-4)}{2} , \ \frac{2+ (-6)}{y} \\\\mid-point (o) = \frac{0}{2} , \ \frac{-4}{2} \\\\mid-point (o) = (0, \ -2)[/tex]
The coordinates of point M is calculated as follows;
point M divides the segment into 4 equal parts with point O as the mid-point.
M
S--------------|-------------------O-------------------|-------------------Y
|SO| = |OY|
[tex]The \ mid-point \ of \ SO = M\\\\Point \ S = (4,2) \\\\Point \ O = (0,-2) \\\\Point \ M = \frac{4 + 0}{2}, \frac{2 - 2}{2} \\\\ Point \ M = 2, 0 \\\\M = (2,0)[/tex]
Therefore, the coordinates of point M = (2,0)
How much time is between 2:30 pm and 4:15pm?? I need an answer quick!!
Answer:
Step-by-step explanation:
First do 4 -2 to get 2. Then do 30-15 to get 15. It’s 2:15.
You can also do this on a calculator by doing 4.15-2.30. You get 1.85
Remember that time is only up to 60 So you have to subtract 15 from 85 to get 60. So it’s 2 hours and 15 minutes. Hope this helps!

the melting point of ice + common salt =
Answer:
Step-by-step explanation:
Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius). When you add salt, that temperature drops: A 10-percent salt solution freezes at 20 °F (-6 °C), and a 20-percent solution freezes at 2 °F (-16 °C). On a roadway, this means that if you sprinkle salt on the ice, you can melt it.

What is parallelogram?The Greek word "parallelogram on," which means "bounded by parallel lines," is where the term "parallelogram" comes from. As a result, a parallelogram is a quadrilateral with parallel lines defining its boundaries. The opposite sides are parallel and equal in this shape. There are three main classes of parallelograms: square, rectangle, and rhombus each have their own distinct characteristics.
Given a parallelogram NPQR
and NS = 20 to find the value of SQ
since S is the intersecting point of diagonals of parallelogram,
so NS = SQ
The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal. The sum of the squares of a parallelogram's diagonals and all of its sides is the same.
SQ = 20
Hence for parallelogram SQ = 20.

Find the area of the circle. Use 3.14 for p.
Answer: B
Step-by-step explanation:
How do you solve this proof?
Answer:
Angle = A
A7 = A4 (Alternate interior angles)
A14 = A11 (Vertically opposite angles)
A11 = A6(Corresponding angles)
A4 = A14 (Given)
From this, we can get A6 = A4
A6 and A4 are alternate angles and are equal. So c and d are parallel.
A7 + A10 = 180 (Linear pair of angles) - ( 1 )
A13 = A10(Alternate interior angles)
Putting A13 in place of A10 in ( 1 ),
A7 + A13 = 180
Hence proved

State the slope and y-intercept for the graph of the equation -8x + y = -12.
Show your work!!
Answer:
Slope is 8 and Y-Intercept is -12
Step-by-step explanation:
Move the -8x over to the right side by adding it, You are now at
y=-12+8x
Move these around and you are now at
Y=8x-12
Answer:
Step-by-step explanation:
Remark
y must have a numerical coefficient of 1. This equation does. If it does not, then you must divide through by whatever is in front of the y.To read the slope, you must have x and its coefficient on opposite sides of the equal sign. So you get y = 8x - 12 when you add 8x to both sidesNext, the y intercept is found when x = 0y = 8x - 12y = 8(0) - 12y = - 12The y intercept is -12 or in point form (0, - 12)Answer
slope = 8
y intercept = - 12

A sports marketing company is interested in how many hours teenagers in a town spend watching sports. They randomly select 40 teenagers in this town and ask how many hours per week they spend watching sports. The mean amount is 6.25 hours with a standard deviation of 4.33 hours. Which of the following is the 90% confidence interval for the true mean amount of time teenagers from this town watch sports?
Find the t-table here.
(4.396, 8.104)
(4.865, 7.635)
(5.097, 7.404)
(5.245, 7.256)

The 90% confidence interval for the true mean amount of time teenagers from this town watch sports is (5.097, 7.404).
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The formula for the confidence interval is:
CI = x ± tα/2 × (s/√n)
where x is the sample mean,
s is the sample standard deviation,
n is the sample size, and
tα/2 is the t-value with (n-1) degrees of freedom and a confidence level of 90%.
From data (x) is 6.25 hours and
s= 4.33 hours.
We also know the sample size (n) is 40.
To find the t-value with (n-1) degrees of freedom and a confidence level of 90%, we can use a t-table.
For 39 degrees of freedom and a confidence level of 90%
Let us find that the t-value is 1.684.
Substituting the values we have into the formula, we get:
CI = 6.25 ± 1.684 × (4.33/√40)
CI = (5.097, 7.404)
Therefore, the 90% confidence interval for the true mean amount of time teenagers from this town watch sports is (5.097, 7.404).

5. To determine the number of kids under the age of 5 in your neighborhood, you sit outside of
your apartment and count the number of kids under 5 that pass by between the hours of 7AM
and 8AM. Do you think this method will provide you with a representative random sample?
Explain your reasoning.
Answer:
It will not provide a representative random sample.
Step-by-step explanation:
This is because kids under five will only leave the house if they are going to the park or doing something with there parents. They don't go to school either so they most likely won't leave during the hours of 7 AM and 8 AM.

What is -1/2 (-5/6 plus 1/3) simplified
Answer:
0.25 or 5/12 - 1/6
Step-by-step explanation:
-1/2(-5/6+1/3), do PMDAS. (-5/6) = -0.833 (repeated) and (1/3) = 0.333 (repeated) and you add them both (-0.833 + 0.333) = -0.5 and -1/2 = -0.5 and when you multiply them both it would equal 0.25. or another explanation for the answer is 5/12 = 0.41666666666 and 1/6 = 0.16666666666 and when you subtract them both you get 0.25, I hope this was helpful.
