Select the correct answer from each drop-down menu. a comic-strip writer churns out different numbers of comic strips each day. the writer logged the number of comic strips he wrote each day for 16 days and sorted the data in ascending order to create this data set. 1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 8 the data in the distribution is . if the writer writes for two more days and creates 5 and 7 comic strips, respectively, the difference of the mean and the median for the new data set is .
Mean = 3.5
Median = 3
Distribution is negatively skewed.
What is skew in the distribution?
The distribution has no skewness if the mean and median are equal.
The median exceeds the mean in a favorably skewed distribution.
The distribution is also negatively skewed if the median is lower than the mean.
Given,
Data set : 1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 8
Mean = [tex]\frac{1+1+2+2+2+3+3+3+3+4+4+4+5+5+6+8}{16}[/tex]
Mean = [tex]\frac{56}{16}[/tex]
Mean = [tex]3.5[/tex]
Median = mid value of the data set when the values are arranged in ascending order
Here,
the two mid values = [tex]3, 3[/tex]
Median = [tex]\frac{3+3}{2}[/tex]
Median = [tex]\frac{6}{2}[/tex]

In unitary method we will learn how to find the value of a unit from the value of a multiple and the value of a multiple from the value of a unit.
When we go to the market to buy any article, we ask the shopkeeper to tell the price of the article. This is called unit price. We calculate the price of number of articles, we want to buy, with the help of this unit price. Sometimes, we calculate unit price when the price of a multiple is given.
1 tile in 1/4 foot
So in 4 foot wall the number of tiles = 4/(1/4) = 16 tiles.

Revenue function: r(x) = 60x cost function: c(x) = 12 + 7x profit function: p(x) =
Profit function : p(x) = 53 x - 12
Cost is the total cost of producing the output.
The cost function consists of two different types of costs:
- Variable costs
- Fixed costs.
Variable costs vary with output (number of units produced). Total variable costs can be
expressed as the product of variable costs per unit and the number of units produced. If there are multiple items
manufactured costs are higher.
Fixed costs usually do not vary with performance.
Revenue is the total payment received from the sale of goods or the provision of a service.
The revenue function R() reflects the revenue from selling “” quantity of output items at price
"p" after item.
() =
Profit functions
The profit function P() is the difference between the revenue function R(x) and the total cost function C()
So P() = R() – C()
=−
Now, Profit = Revenue - Cost
= 60 x - ( 12 + 7 x)
= 60 x -12 -7 x
Profit = 53 x - 12
Hence, Profit function : p(x) = 53 x - 12

Write the equation of the line which passes through (5, −2) and (3, 4) in standard form.
The equation of the line is 3x + y = 1
How to determine the equation of the line?The points are given as:
(5, −2) and (3, 4)
Start by calculating the slope (m)
m =(y2 - y1)/(x2 - x1)
This gives
m = (4 + 2)/(3 - 5)
Evaluate
m = -3
The equation is then calculated as:
y = m(x - x1) + y1
This gives
y = -3(x + 2) +5
So, we have:
y = -3x - 6 + 5
Evaluate the like terms
y = -3x - 1
Rewrite as:
3x + y = 1
Hence, the equation of the line is 3x + y = 1

find the inverse of
f(x) = -6xˆ2 + 24x - 100
Answer:
See below
Step-by-step explanation:
y = -6x^2 + 24x-100
solve for 'x'
y + 100 = -6x^2 + 24x = -6(x^2-4x) complete the square for x
(y+100) /(-6 ) = (x-2)^2 -4 add 4 to both sides
(y+100)/(-6) +4 = (x-2)^2 sqrt both sides
sqrt [ ( y+100)/(-6) + 4 ] + 2 = x change x and y
y = ± sqrt [ (x+100)/(-6) + 4 ] + 2 simplify (if needed)
y = ± sqrt( -x/6 -12.666) + 2

Answer:
b = 21
Step-by-step explanation:
In general for these trig problems look for the angle whose measure you are given or need to find and for the sides you are given lengths or whose sides you need to find.
Given:
side AB = 10 cm
m<C = 25°
Find:
side AC
The angle of interest here is <C whose measure is 25°.
Now look at the given side and the side you are looking for with respect to angle C, the given angle.
For angle C, AC is the adjacent leg.
For angle C, AB is the opposite leg.
Which trig function relates the opposite leg to the adjacent leg?
It is the tangent, since, in general, tan X = opp/adj.
tan C = opp/adj
tan 25° = AB/AB
tan 25° = 10 cm/b
Solve for b.
b × tan 25° = 10 cm
b = 10 cm / tan 25°
Using your calculator, divide 10 by the tangent of 25°.
b = 21.44506...
Answer: b = 21
Answer:
[tex]b = \bf 21 \space\ cm[/tex]
Step-by-step explanation:
• To solve for a side using SOH CAH TOA, first check the angle whose measure is given.
In this case, we know ∠ C is 25°.
• Next we have to figure out the relationships between the given angle and two sides: one side whose length we know, and the other whose length we have to find.
In this case, the side opposite to ∠ C is known to be 10 cm, and the side adjacent to ∠ C is AC, whose length, b, we have to find.
• The trigonometric ratio that relates the adjacent and opposite sides of an angle is tan, where:
[tex]\boxed{tan \theta = \frac{opposite}{adjacent} }[/tex] .
We can use this relationship to calculate the value of b:
⇒ [tex]tan (25 \textdegree) = \frac{10}{b}[/tex]
Solving for b:
⇒ [tex]b \cdot tan (25 \textdegree) = 10[/tex]
⇒ [tex]b = \frac{10}{tan (25 \textdegree)}[/tex]
⇒ [tex]b = 21.45[/tex]
⇒ [tex]b \approx \bf 21 \space\ cm[/tex] (rounded to the nearest whole number)

At-home tutoring is a type of tutoring that takes place in the student's house. Tutoring is frequently related to an academic subject or test preparation. This is in contrast to tutoring centers or after-school programs that give tutoring.A home tutor is an instructor who conducts classes in the convenience of your own home. Because they give personalized attention, these classes are frequently more expensive than those offered at tuition centers. In-home tutoring typically has fewer pupils, and the lessons are even more exclusive.Tutoring's goal is to help students help themselves, or to aid or guide them to the point where they are independent learners and no longer require a tutor.Therefore, Rosa is providing home-based tutoring.

a. place the compass needle on m and keeping the compass width the same, draw two arcs that intersect the line AB
What are the steps to construct a perpendicular line from an external point?To construct a perpendicular line, a compass and a scale are used.
Consider a line AB and an external point M.
Step 1:
Place the compass needle on M and keeping the compass width the same, draw two arcs that intersect the line AB.
Step 2:
Name the two intersecting points on line AB as X and Y.
Draw the arcs from these two points to the opposite side of point M with the same compass width.
Step 3:
Name the intersecting point of two arcs as N.
Draw a line connecting the two points M and N using scale.
Step 4:
Using a protractor, measure the angle of the line MN with the line AB.

The solutions of the equations x - 5y = 0 and 15x + 10y = 17 at x and y is 1 and 1/5 respectively.
Two algebraic expressions separated by an equal symbol in between them and with the same value of the expression are called equations.
Given that:
The linear equations are:
x - 5y = 0
15x + 10y = 17
Solve the equations using elimination method:
Multiply equation 1 by 2
2(x - 5y) = 0
15x + 10y = 17
This can be solved as:
2x-10y = 0.....(1)
15x + 10y = 17....(2)
On subtracting equation 1 from 2
17x = 17
x = 1
The value of x is 1.
Substitute the value of x in equation (1)
2(1)-10y = 0
2=10y
