The line passing through point [tex]F[/tex] that is skew to [tex]\overleftrightarrow{EH}[/tex] is [tex]\overleftrightarrow{CF}[/tex] .
Skew lines are two parallel but non-intersecting lines. The two lines that pass through the opposing edges of a normal tetrahedron are a straightforward illustration of a pair of skew lines.
To check if two lines are skew we need to check by following the steps mentioned below:
Step 1: Find lines that do not cross one another.
Step 2: Verify that these line pairs are not also parallel to one another.
Step 3: Check whether these non-intersecting, non-parallel lines are non-coplanar. If the answer is affirmative, the selected pair of lines are skew.
Therefore, the line [tex]\overleftrightarrow{CF}[/tex] passes through point F, the line is not parallel to the line [tex]\overleftrightarrow{EH}[/tex] and is also non-coplanar. Both the lines do not intersect each other.
Hence, [tex]\overleftrightarrow{CF}[/tex] and [tex]\overleftrightarrow{EH}[/tex] are skew lines.

One summer day, amelia decided to count the number of people wearing sandals at the mall. she compared the number of people wearing sandals at the mall to the total number of people she saw at the mall and developed this equation: s=35x+12s=35x+12 if she counted a total of 325 people, how many people were probably wearing sandals at the mall?
Answers
Answer:
Step-by-step explanation:
325
Number of people probably wore sandals at the mall = 9 people
Let 's' denote the total number of people Amelia counted at the mall.
Let x be the number of people wearing sandals out of them.
The equation developed by Amelia according to this is,
s = 35x + 12
This is a linear equation written with s in terms of x .
Total people counted by Amelia = 325
So we have to find the value of x when s = 325.
Substituting s = 325 to the equation,
325 = 35x + 12
⇒ 325 - 12 = 35x
⇒ x = (325 - 12)/35
⇒ x = 8.9 ≈ 9
Since x denote the number of people wearing sandals, we take x = 9

9. Suppose the shipping company were packing balls with a diameter of
2 inches instead of cubes. Would the large box hold more balls or
fewer balls than boxes? Explain your answer.
Answers
Larger boxes may hold more or fewer balls than smaller ones. The answer to this question must be a sphere because they have the lowest volume value.
What exactly do you mean by volume?Volume is the quantity of three-dimensional space occupied by a liquid, solid, or gas.. Although there are many different units that can be used to indicate volume, the most common ones are liters, cubic meters, gallons, milliliters, teaspoons, and ounces.
According to the information provided,
One should calculate the volumes of the figures to find out if the larger box will carry more cubes or spheres, and the result that yields the smaller value must be the solution.
Volume of cube = (edge)³ = (2 in)³
= 8 in³
Volume of sphere = (4πr³)/3
where r is the radius and is equal to half of the length of the sides. Substituting,
Volume of sphere = (4π)(1 in)³ / 3 = 4.19 in³
Since spheres give the smaller value for volume, the answer to this item would have to be SPHERE.

value of the median in the situation = 49
Solution :
Median :
A Median is defined as the middle value in a given set of numbers or data. In Mathematics, there are three different measures, which are used to find the average value for a given set of numbers. They are mean, median, and mode. These three measures are called the measures of central tendency. The average value of the given data is given by mean. The middle value of the given data is defined by a median. The repeated value of the given data is defined by mode.
Mean :
The mean is estimated by dividing the sum of all the numbers by the count of the numbers.
Median Formula
Based on the definition, the formula to find the median of the dataset is given by:
If the given number of observations/data is odd, then the formula to calculate the median is:
Median = {(n+1)/2}th term
If the given number of observations is even, then the formula to find the median is given by:
Median = [(n/2)th term + {(n/2)+1}th term]/2
Where,
“n” is the number of observations.
Count of variety A = 10
Median = [(n/2)th term + {(n/2)+1}th term]/2
Median = [(10/2)th term + {(10/2)+1}th term]/2
Median = [5th term + {6th term}]/2
Median = [49 + 49]/2
Median = [98]/2
Median = 98/2 = 49
value of the median in the situation = 49

The equation of the line that passes through (2, -6) and is perpendicular to the given line is y = -x -4
Equation of a lineFrom the question, we are to determine the equation of a line that passes through (2, -6) and it perpendicular to y = x + 4
If two lines are perpendicular, the product of their slope is -1.
That is,
m₁m₂ = -1
First,
We will determine the slope of the line that the equation was given
y = x + 4
Comparing with the slope-intercept form of the equation of a straight line
y = mx + b
Where m is the slope
and b is the y-intercept
By comparison
m = 1
The slope of the line that the equation was given is 1
Thus,
The slope of the line that is perpendicular to this line is -1
From the given information,
The line passes through the point (2, -6)
Using the point-slope form of the equation of a line
y - y₁ = m(x - x₁)
Then,
y - -6 = -1(x - 2)
y + 6 = -x + 2
y = -x + 2 - 6
y= -x -4
