Answer:
increase
Step-by-step explanation:
Given data is: 71, 67, 67, 17, 69, 84, 21, 87Arranging in ascending order we find: 17, 21, 67, 67, 69, 71, 84, 87 Here N = 8 (Even number)N/2 = 4 and N/2 + 1 = 54th term = 67, 5th term = 69-> median = Sum of 4th and 5th term/2 = (67 + 69)/2 = 132/2 = 66Now, when one of the 67 is replaced by 71, the new data set in ascending order will be: 17, 21, 67, 69, 71, 71, 84, 87Here, 4th term = 69, 5th term = 71New median = (69 + 71)/2 = 140/2 = 70-> new median > initial medianCONCLUSION: Median will increase if the number 71 replaced one of the 67's in the set.

Given: ∠ABC and ∠CBD are complementary angles and m∠ABC=35°
Prove:m∠CBD=55°
Answer:
we know that sum of two complementary angles always equals to 90°
now ∠ABC and ∠CBD are complementary which means ∠ABC + ∠CBD = 90
∠ABC = 35° given
so ∠CBD = 90° - ∠ABC = 90° - 35° = 55°
therefore hence proved ∠CBD = 55°

A plane convex lens is made of glass ( n = 1. 5) with one flat surface and the other having a radius of 20 cm. What is the focal length (in cm) of the lens?
The focal length of the lens is 40cm.
What is the focal length?The distance between the center of a lens or curved mirror and its focus.
A plane convex lens is made of glass ( n = 1. 5) with one flat surface and the other having a radius of 20 cm.
The focal length of the lens is given by the following formula;
[tex]\rm \dfrac{1}{f}=(n-1) \left ( \dfrac{1}{r_1}-\dfrac{1}{r_2} \right)\\\\Where; \ r_1 =\infty , \ r_2=20, \ and \ n = 1.5[/tex]
Substitute all the values in the formula;
[tex]\rm \dfrac{1}{f}=(n-1) \left ( \dfrac{1}{r_1}-\dfrac{1}{r_2} \right)\\\\\rm \dfrac{1}{f}=(1.5-1) \left ( \dfrac{1}{\infty}-\dfrac{1}{20} \right)\\\\ \rm \dfrac{1}{f}=(0.5) \left ( 0-\dfrac{1}{20} \right)\\\\ \dfrac{1}{f} = \dfrac{-0.5}{20}\\\\\dfrac{1}{f}=-0.025\\\\f = \dfrac{-1}{0.025}\\\\f=-40[/tex]
Hence, the focal length of the lens is 40cm.

Tried to do this one on my own but still dont get how to do it.
Answer:
238
Step-by-step explanation:
First, you must find the ratio between the one measurement of the larger octagon and the smaller octagon. Just divide 28 by 4 to get 7. This is what you have to multiply the perimeter by to get the larger octagon's perimeter. 34 times 7 equals 238. There are multiple ways to do this problem but this way is the simplest.

A line passes through the two points (-4,6) and (2,-5). Calculate the following parts:
A line passes through the two points (-4,6) and (2,-5). 11x +6y - 80 = 0 is the given line equation.
What is the slope of a line which passes through points ( p,q) and (x,y)?Its slope would be:
[tex]m = \dfrac{y-q}{x-p}[/tex]
The slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.
The slope m of the line is given as
[tex]m = \dfrac{y-q}{x-p}\\\\ m = \dfrac{-5-6}{2+4}\\\\ m = \dfrac{-11}{6}[/tex]
The equation of a line is
[tex]( y -y_0) = m (x - x_0)\\\\( y -6) = \dfrac{-11}{6} (x+4)\\\\6( y -6) = (-11) (x+4)\\\\6y -36 = (-11x +44)\\\\11x +6y - 80 = 0[/tex]

Y-intercept of x- 2y = -10
Please help
Answer:
y = [tex]\frac{1}{2} x\\[/tex]+5
Step-by-step explanation:
Y-intercept 5
Answer:
y- intercept = 5
Step-by-step explanation:
to find the y- intercept let x = 0 in the equation and solve for y
this relies on the fact that when the line crosses the y- axis the x- coordinate is zero, then
0 - 2y = - 10 , that is
- 2y = - 10 ( divide both sides by - 2 )
y = 5
then y- intercept = 5
A 60 foot by 20 foot garden is enclosed by a fence. To increase the area of the garden, while still using the same fence, its shape is changed to a square. By how many square feet does this enlarge the garden
The increase in square feet when the garden is enlarged is 400 square feet.
What is the increase in square feet?The first step is to determine the perimeter of the fence:
Perimeter = 2( length + width)
2 (60 + 20)
= 160 feet
When the shape of the garden is changed to a square, the perimeter of the square and the rectangle has to be the same.
Length of side of the square = 160 / 4 = 40 feet
Area of the square = 40 x 40 = 1600 square feet
Area of the garden = 60 x 20 - 1200 square feet
Difference = 1600 - 1200 = 400 square feet

x 1.3 1.6 1.9 2.2
y 1.82 2.24 2.66 3.08
What is the constant of proportionality?
Enter your answer as a decimal in the box.
Reason:
Pick any column and divide y over x
column one: y/x = (1.82)/(1.3) = 1.4column two: y/x = (2.24)/(1.6) = 1.4column three: y/x = (2.66)/(1.9) = 1.4column four: y/x = (3.08)/(2.2) = 1.4You only need to pick one column when it comes to showing your work.
The constant of proportionality is 1.4
