Answer:
a.) PED = 5
b.) PED = 5
c.) PED = 0.05
Step-by-step explanation:
Here , PED = Price elasticity of demand
a.)
Given - The price of a smartphone is currently £200, and the quantity demanded is 4m. Next year the price falls to £180 and the quantity demanded rises to 6m.
PED = (Change in quantity demanded)×[tex]\frac{Initial Price}{Initial Quantity demanded}[/tex]
Now,
Change in quantity demanded = [tex]\frac{6 - 4}{180 - 200}[/tex] = [tex]\frac{2}{20} = \frac{1}{10}[/tex]
⇒PED = [tex]\frac{1}{10}[/tex]×[tex]\frac{200}{4}[/tex] = 5
b.)
Given -The price of pens today is £1, and the quantity demanded is 1m. Next year the price rises to £1.10 and the quantity demanded falls to 950,000.
Change in quantity demanded = [tex]\frac{1000000 - 950000}{1.10- 1}[/tex] = [tex]\frac{50000}{0.10} = 500000[/tex]
⇒PED = [tex]500000[/tex]×[tex]\frac{1}{1000000}[/tex] = 5
c.)
Given -The price of a daily newspaper today is £1.50p, and the quantity demanded is 2m. Next year the price falls by 30p and the quantity demanded rises to 2.2m
Change in quantity demanded = [tex]\frac{2.2 - 2}{30 - 1.50}[/tex] = [tex]\frac{0.2}{28.50} = \frac{20}{2850} = \frac{2}{285}[/tex]
⇒PED = [tex]\frac{2}{285}[/tex]×[tex]\frac{1.50}{2}[/tex] = [tex]\frac{15}{2850}[/tex]= [tex]\frac{1}{190}[/tex] = 0.005

Find the midpoint of AC is at -2 and C is at 3 on a number line
The value of midpoint of AC will be 0.5.
What is Number line?Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
Given that;
Point A is at - 2 and C is at 3 on the number line.
Now,
Since, Point A is at - 2 and C is at 3 on the number line.
Hence, The midpoint of AC = (- 2 + 3 ) / 2
= 1/2
= 0.5
Thus, The midpoint of AC = 0.5

WILL GIVE BRAINLIEST, PLEASE EXPLAIN J=HOW TO FIGURE THIS PROBLEM OUT THANK YOU. The figure below shows a shaded region and a non-shaded region. Angles in the figure that appear to be right angles are right angles.
A picture of a rectangle is shown. The bottom of the rectangle is labeled 16 ft. The right side of the rectangle is labeled 8 ft. At the bottom left side of the rectangle there is a label that reads 2 ft. Inside the rectangle is a shaded region. The bottom of the region is labeled 8 ft and this side is perpendicular to the left side of the rectangle. The right side of the shaded region has a perpendicular line segment extending upward that is labeled 2 ft. At the top of this line segment is another line segment perpendicular to the right that reads 2 ft. At the end of this line segment is a perpendicular line segment extending upward that reads 1 ft. There is a line segment joining the end of this line segment with the top left corner of the rectangle.

write the slope intercept form of the equation of each line
Answer:
Y= - 1/5x-4
Step-by-step explanation:
slope intercept form: y=mx+b
Slope formula: rise/run
(5,-5) AND (0,-4)
-5+-4= -1
5+0= 5 AKA - [tex]\frac{1}{5}[/tex] or -1/5
The m in y=mx+b is the slope, the equation above is the sloe formula meaning -1/5 is the slope. The b is the y, when it is at 0. The y at 0 for this equation is -4. Thus, when plugging in the equation, y=-1/5x-4

Which equation represents a line that passes through (0,–8) and (–5,–23)?
A) y = 4x – 8
B) y = –8x + 3
C) y = 5x – 8
D) y = 3x – 8
The equation of line that passes through points (0,-8) and (-5,-23) is y=3x-8 which is option d.
Given that the line passes through (0,-8) and (-5,-23).
We are required to find the equation of the line that passes through (0,-8) and (-5,-23).
Equation is like a relationship between two or more variables expressed in equal to form. Equation of two variables look like ax+by=c. It may be linear equation, quadratic equation, cubic equation, and many more depending on the power of the variable.
The formula to form the equation from two points is as under:
[tex](y-y_{1}) =(y_{2} -y_{1} )/(x_{2} -x_{1} ) * (x-x_{1} )[/tex] in which [tex](x_{1} ,y_{1} ),(x_{2} ,y_{2} )[/tex] are the points.
(y+8)=(-23+8/-5-0)(x-0)
y+8=(-15/-5) x
y+8=3x
y=3x-8
Hence the equation of line that passes through points (0,-8) and (-5,-23) is y=3x-8 which is option d.

A glass vase factory recently produced 4 vases that were chipped and 16
vases that were not. Considering this data, how many of the next 10 vases
would you expect to be chipped?
Answer:
2
Step-by-step explanation:
4 chipped + 16 not chipped = 20 total
4 / 20 = 1/5 or 20% chance that vase will be chipped
Set up a proportion or find 20% of 10.
[tex]\frac{1}{5} = \frac{x}{10}[/tex] x = 2 (ten is on denominator because it's the total amount of vases)
or 10 * 0.2 = 2
A pool is surrounded by a rectangular fence with a
perimeter of 72 yards. If the length of the fence is 3
times the width, what is the length of the fence, in yards?
Answer:
width is 33
Step-by-step explanation:
width (b) =?
length(l)=3
perimeter (p)=?
now,
perimeter = 2(l+b)
or,72= 2(3+ b)
or,72/2= 3+b
or,36= 3+b
or,36-3= b
or,33= b
therefore width is 33
