Answer:
The coordinates of point S are (4,-7).
Step-by-step explanation:
Given the locations of points S and T, the midpoint coordinates are set by midpoint formulas:
[tex]\bar x = \frac{x_{S}+x_{T}}{2}[/tex] and [tex]\bar y = \frac{y_{S}+y_{T}}{2}[/tex]
Where:
[tex]x_{S}[/tex], [tex]x_{T}[/tex] - x-Components of S and T.
[tex]y_{S}[/tex], [tex]y_{T}[/tex] - y-Components of S and T.
The coordinates of S are cleared:
[tex]x_{S} = 2\cdot \bar x -x_{T}[/tex]
[tex]y_{S} = 2\cdot \bar y - y_{T}[/tex]
If [tex]\bar x = 2[/tex], [tex]\bar y = -2[/tex], [tex]x_{T} = 0[/tex] and [tex]y_{T} = 3[/tex], the equations are now solved:
[tex]x_{S} = 2\cdot (2) -0[/tex]
[tex]x_{S} = 4[/tex]
[tex]y_{S} = 2\cdot (-2)-3[/tex]
[tex]y_{S} = -7[/tex]
The coordinates of point S are (4,-7).

The manager of a factory collected data in order to analyze the relationship
between the number of hours of training a worker receives and
the worker's error rate. The line of best fit for the collected data is y = 0.1 -0.005x, where x is the number of hours of training a worker
receives and y is the error rate.
What approximate error rate should the manager expect for a worker who receives 6 hours of training?

To simplify this expression, we combine all the like terms. We cannot solve for x because there is no equal sign and/or no value for x.
Equation: (10x² - 10x - 6) + (x + 6)
[tex]\bf Step~1:[/tex]
-10x and x are like terms. Remember: there is an invisible 1 behind the variable x. We add these like normal numbers.
[tex]\bf -10x+1x=-9x[/tex]
[tex]\bf Step~2:[/tex]
-6 and 6 are also like terms. Again, we add them as written.
[tex]\bf -6+6=0[/tex]
Since our answer is 0, we do not have to write it in our simplified expression.
[tex]\bf Step~3:[/tex]
Now, let's add the terms together. Since 10x² doesn't have any like terms, we just let it be. We take our previous number, -9x, and we add it to 10x².
[tex]\bf 10x^2+-9x[/tex]
[tex]\large\boxed{\bf Our~final~answer:10x^2-9x}[/tex]
Leanne works at a restaurant. For dinner, there is a choice of 3 main dishes and 2 sides.
Main Dish: Burger(B), Chicken (C), Pasta (P)

Is Leanne correct? Use the drop-down menus to explain your reasoning.
Click the arrows to choose an answer from each menu.
For each main dish, there are Choose... different sides a person can choose. So, there are
a total of Choose... possible ways a person could choose their dinner. Leanne is
Choose...
Answer:
I feel like its that but im rlly not sure.
Step-by-step explanation:
Leanne's list is incorrect and there are 3 different sides a person can choose. So, there are a total of 6 possible ways a person could choose their dinner.
How to determine the number of combinations?The given parameters are:
Main Dish: B, C and P
Sides: A and F
Using the above parameters, the combination of dishes are:
BA, BF, CA, CF, PA and PF
Hence, we can conclude that Leanne list is incorrect
Also, we have:
Dish = 3
Sides = 2
So, the number of dinner to choose is:
Dinner = 3 * 2 = 6
Hence, a person could choose their dinner in 6 ways

if y= 1/5 when x=3, find y when x=4, given that y varies directly with x
Answer:
[tex]y = \frac{4}{15} [/tex]Step-by-step explanation:
To find y when x=4, we must first find the relationship between them
The statement
y varies directly with x is written as
[tex]y \: \: \: \alpha \: \: \: kx[/tex]where k is the constant of proportionality
From the question
when y = 1/5
x = 3
Substitute the values into the above formula and solve
That's
[tex] \frac{1}{5} = 3k \\ 15k = 1 \\ k = \frac{1}{15} [/tex]So the formula for the variation is
[tex]y = \frac{x}{15} [/tex]From the question
when x = 4
[tex]y = \frac{4}{15} [/tex]Hope this helps you

A rock has a density of 4.56 g/mL. If it weighs 235 g, what is its volume?
Answer:
51.54mL
Step-by-step explanation:
Density can be defined as the mass per unit volume of a particular object , substance or compound.
Density tell us how heavy or dense that object, substance or compound is.
Mathematically, the formula for Density = Mass(grams)/Volume(ml or cm³)
In the above question, a rock has the following criteria:
Density = 4.56 g/mL.
Mass = 235 g
Volume is unknown.
Imputing this values into the formula for Density, we have:
4.56g/mL = 235g/ Volume
Cross Multiply
4.56g/mL × Volume = 235g
Volume = 235g/4.56g/mL
Volume = 51.535087719mL
Approximately, the volume of the rock to 2 decimal places = 51.54mL
simply 12 to the power of 16 over 12 to the power of 4

Point Fis on line segment EG . Given FG = 4 and EF = 9 determine the length EG
Answer:
EG is 13.
Step-by-step explanation:
So we have a line segment EG.
Point F is somewhere on EG.
And we are given that FG is 4 and EF is 9.
Therefore, the length of EG will be the combined lengths of FG and EF. In other words:
[tex]EG=EF+FG[/tex]
Substitute 9 for EF and 4 for FG. Thus: "
[tex]EG=9+4[/tex]
Add:
[tex]EG=13[/tex]
So, the length is EG is 13.
And we're done!
