Your teacher draws a line segment on the board that connects points A and B in the coordinate plane. Using what you know about midpoints, explain how can you find the point that is 1/4 of the distance from A to B?
Answer:
The coordinates of the point, (x₂, y₂), 1/4 distance from A to B is given as follows;
[tex](x_2, \ y_2) = \left (x_1 + \dfrac{x_3 - x_1}{4}, \ y_1 + \dfrac{y_3 - y_1}{4} \right)[/tex]
Step-by-step explanation:
The steps used to find the point, P, 1/4 of the distance from A to B is as follows
Let the coordinate of the point A = (x₁, y₁) and the coordinate of the point B = (x₃, y₃)
Therefore, the coordinates of the point, P, (x₂, y₂), is given from the following relationship;
The coordinates of P 1/4 distance from A to B = (x₂, y₂) = (x₁ + (x₃ - x₁)/4, y₁ + (y₃ - y₁)/4)
Where;
x₂ = x₁ + (x₃ - x₁)/4
y₂ = y₁ + (y₃ - y₁)/4
By plugging in the values for x₁, y₁, x₃, and y₃, we can find the coordinates of the point P, 1/4 of the distance from A to B
The coordinates of P 1/4 distance from A to B = (x₂, y₂) = (x₁ + (x₃ - x₁)/4, y₁ + (y₃ - y₁)/4)

Triangle A prime B prime C prime has vertices A prime at 6 comma 4, B prime at 2 comma 0, and C prime at 4 comma negative 2. Which set of transformations has been performed on triangle ABC to form triangle A′B′C′? (4 points) a Dilation by a scale factor of 4 followed by reflection about the x-axis b Dilation by a scale factor of 2 followed by reflection about the x-axis c Dilation by a scale factor of 4 followed by reflection about the y-axis d Dilation by a scale factor of 2 followed by reflection about the y-axis
Answer:
d Dilation by a scale factor of 2 followed by reflection about the y-axis
Step-by-step explanation:
In each case, the transformation is ...
(x, y) ⇒ (-2x, 2y)
So, a dilation by a factor of 2 is involved. That is what multiplies the coordinates by 2. Reflection in the y-axis is what negates the x-coordinate.
The transformations are ...
Dilation by a scale factor of 2 followed by reflection about the y-axis

A truck is carrying 102 bushels of sweet potatoes, 101
bushels of tangerines, and 103 bushels of
summer squash. What is the total weight of the crops?
Answer:
306
Step-by-step explanation:
101+102+103=306
Answer:
71,400
Step-by-step explanation:
1) Given, the crops and their weight:
apples = 40 lbs
sweet potatoes = 60 lbs
tangerines = 40 lbs
summer squash = 65 lbs
2) The Truck is carrying:
10² bushels of sweet potatoes = 60 x 100 = 6,000 lbs
10¹ bushels of tangerines = 40 x 10 = 400 lbs
10³ bushels of summer squash = 65 x 1000 = 65,000 lbs
3) All together, the total weight of the crops are:
6,000 lbs + 400 lbs + 65,000 lbs = 71,400 lbs.
The total weight of the crops is 71,400 lbs.

Evaluate inverse functions
The table below shows some inputs and outputs of the invertible function f with domain all real numbers.
x. |-7|11|-13|6|5|-9|
f(x). 7|12|8|-7|13|5|
Find the following values:
f-1(F-1(13)) =
f-1(8) =
Part 1
Answer: -9---------------------------
Explanation:
Let's focus on evaluating [tex]f^{-1}(13)[/tex] first. We need to look at the table and locate f(x) = 13. So we're looking in the f(x) row where 13 shows up. That's in the second to last column. Right above that we have x = 5
This means f(5) = 13 and [tex]f^{-1}(13) = 5[/tex]. The inverse undoes the f(x) function. So the input x and output y values swap places. This is why we're reading the table in reverse.
We can replace all of [tex]f^{-1}(13)[/tex] with 5 to go from [tex]f^{-1}(f^{-1}(13))[/tex] to [tex]f^{-1}(5)[/tex]
Then we repeat the process of using the table. Locate 5 in the f(x) row. This is in the last column. The value above that is x = -9
So f(-9) = 5 and [tex]f^{-1}(5) = -9[/tex]
Overall, [tex]f^{-1}(f^{-1}(13)) = -9[/tex]
===============================================
Part 2
Answer: -13---------------------------
Explanation:
Same idea as before. Locate 8 in the f(x) row. The value above this is x = -13
This means f(-13) = 8 and [tex]f^{-1}(8) = -13[/tex]
The value of [tex]f^{-1}(f^{-1}(13))[/tex] is -9
The value of [tex]f^{-1}[/tex] (8) is 13
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
From the table,
f(5) = 13
This can be written as,
[tex]f^{-1}[/tex] (13) = 5 _____(1)
f(-13) = 8
This can be written as,
[tex]f^{-1}[/tex] (8) = 13 ______(2)
f(-9) = 5
This can be written as,
[tex]f^{-1}[/tex] (5) = -9 _______(3)
Now,
[tex]f^{-1}(f^{-1}(13))[/tex]
= [tex]f^{-1}[/tex] (5) [ from (1) ]
= -9 [ from (3) ]
Now,
[tex]f^{-1}[/tex] (8) = 13 [ from (2) ]
Thus,
[tex]f^{-1}(f^{-1}(13))[/tex] = -9
[tex]f^{-1}[/tex] (8) = 13

Information about the proportion of a sample that agrees with a certain statement is given below. Use StatKey or other technology to estimate the standard error from a bootstrap distribution generated from the sample. Then use the standard error to give a 95% confidence interval for the proportion of the population to agree with the statement. StatKey tip: Use "CI for Single Proportion" and then "Edit Data" to enter the sample information. Click here to access StatKey. In a random sample of 400 people, 112 agree and 288 disagree. Estimate the standard error using 1000 samples. Round your answer to three decimal places.
Answer:
a) Standard Error = 0.010
b) 95% Confidence Interval = (0.0924 , 0.1316)
Step-by-step explanation:
a) The formula for Standard Error = √Sample Proportion (1 - sample proportion)/n
Standard Error = √p (1 - p)/n
We are told in the question that:
In a random sample of 400 people, 112 agree and 288 disagree. Estimate the standard error using 1000 samples
p = x/n
n = 1000 because we were told to use it instead of 400
x = number for people that agree = 112
p = 112/1000
p = 0.112
Standard Error = √p (1 - p)/n
= √0.112 (1 - 0.112)/1000
= √0.112 × 0.888/1000
= √0.099456 /1000
= √0.000099456
= 0.0099727629
Approximately to 3 decimal places = 0.010
Therefore, the standard error is 0.010
b) The Question above also asked that we solve for the 95% Confidence Interval
The formula =
p ± z × Standard Error
p = 0.112
z score for 95% confidence interval = 1.96
Standard Error = 0.010
Confidence Interval =
0.112 ± 1.96 × 0.010
= 0.112 ± 0.0196
0.112 - 0.0196
= 0.0924
0.112 + 0.0196
0.1316
Therefore, the 95% confidence interval = (0.0924 , 0.1316)
