Answer:
1. 25
Step-by-step explanation:
First, you need to place the numbers in ascending order, meaning from smallest to largest.
You calculate the range by taking the largest number and subtract the smallest from it, so in this case: 42-17 = 25
Mean (average), just add the numbers up and divide by how many numbers you have
III. Once you find the Mean and you placed them in order from smallest to largest, you can find this answer
Median (middle) - which number is in the middle so after you place them in order which is in the middle if you have an odd number of marks, but since you have 12 marks then take the 2 center numbers, add them up, and divide by 2, in other words, get the mean of the middle numbers and that will give you the median in this problem
Mode, which number appears the most times repeated
Answer:
i. 25 (range = the difference between the highest and lowest number)
ii. 30.41 (mean = sum of all numbers divided by the how many numbers there are)
iii. 6
iv. 35
v. 35
Question 3
The distance from Mason's house to Kevin's house is about 5 x 10 to the power of 5 inches. The distance from Mason's house to Chloe's house is about 8 x 10 to the power of 7 inches
The distance from Mason's house to Chloe's house is how many times greater than the distance from Mason's to Kevin's house?
9514 1404 393
Answer:
160
Step-by-step explanation:
Your calculator can compute the ratio of distances for you.
[tex]\dfrac{8\times10^7}{5\times10^5}=\dfrac{8}{5}\times10^{7-5}=1.6\times10^2=\boxed{160}[/tex]
Chloe's house is 160 times as far as Mason's house.

Peter has built a gazebo, whose shape is a regular heptagon, with a side length of $1$ unit. He has also built a pathway around the gazebo, of constant width $1$ unit, as shown below. (Every point on the ground that is within $1$ unit of the gazebo and outside the gazebo is covered by the pathway.) Find the area of the pathway.
Answer:
Area of pathway = 10.375 unit²
Step-by-step explanation:
Given - Peter has built a gazebo, whose shape is a regular heptagon, with
a side length of 1 unit. He has also built a pathway around the
gazebo, of constant width 1 unit, as shown below.
To find - Find the area of the pathway.
Proof -
Central angle = [tex]\frac{360}{7}[/tex] = 51.43°
Now,
Central angle / 2 = [tex]\frac{360}{14}[/tex] = 25.71°
And
height = [tex]\frac{1}{2}.\frac{1}{tan25.41}[/tex] = 1.038
Now,
Inner area of gazebo = 7·[tex]\frac{1}{2}[/tex]·1·(1.038) = 3.634 unit²
Outer area of gazebo = ([tex]\frac{2.038}{1.038}[/tex])²·(3.364) = 14.009 unit²
∴ we get
Area of pathway = Outer area - Inner area
= 14.009 - 3.634
= 10.375 unit²
⇒Area of pathway = 10.375 unit²

Find m and n if the remainder when 8x^3+mx^2-6x+n if divided by (x-1) and (2x-3) are 2 and 8 respectively
Answer:
we have:
8x³ + mx² - 6x + n
= 8x³ - 8x² + (m + 8)x²- (m + 8)x + (m + 2)x - (m + 2) + m + 2+ n
= 8x²(x - 1) + (m + 8)x(x - 1) + (m + 2)(x - 1) + (m + n + 2)
= (x - 1)[8x² + (m + 8)x + m + 2] + (m + n + 2)
because the remainder if divided by (x-1) is 2
=> m + n + 2 = 2
⇔ m + n = 0 (1)
we also have:
8x³ + mx² - 6x + n
= 8x³ - 12x² + (m + 12)x² - 3/2.x.(m + 12) + ( 12 + 3/2.m)x - (9/4.m + 18) + n +9/4m + 18
= 4x²(2x - 3) + 1/2.(m + 12)x(2x - 3) + (3/2m + 12).1/2.(2x - 3) + 9/4m + n + 18
= (2x - 3)(4x² + (m + 12)/2.x + 3/4m + 6) + 9/4m + n + 18
because the remainder if divided by (2x - 3) is 8
=> 9/4m + n + 18 = 8
⇔ 9/4m + n = -10 (2)
from (1) and (2), we have:
m + n = 0
9/4m + n = -10
=> m = -8
n = 8

A rectangle has length (x + 5)cm and width (x –2)cm. Its area is 60 cm 2
Area = length x width
60 = (x+5) (x-2)
60 = x^2 + 3x -10
Subtract 60 from both sides:
x^2 +3x -70 = 0
Solve for x by finding 2 numbers when added together = 3 and when multiplied by each other = -70
x = -10 and 7
Since the sides have to be a positive number we need to use 7
The length = x+5 = 7+5 = 12 cm
The width = x-2 = 7-2 = 5 cm

What quadrant would ( -8, 5 ) - ( 9, -1 ) be
help
Answer:
Quadrant 2
Step-by-step explanation:
-8 - 9 = -17
5 - (-1) = 6
(-17, 6) = second quadrant
What is the answer for this question
-3: y = -2 * (-3) - 7 = 6 - 7 = -1
0: y = -2 * 0 - 7 = -7
3: y = -2 * 3 - 7 = -6 - 7 = -13
6: y = -2 * 6 - 7 = -12 - 7 = =-19
solve the following simultaneous equations 5x+7y = 17 ; 7x+5y = 19
Answer:
[tex]x=2.\ y=1[/tex]
Step-by-step explanation:
[tex]We\ are\ given\ the\ following\ pair\ of\ equations:\\5x+7y=17\\7x+5y=19\\Now,\\As\ the\ co-efficients\ of\ none\ of\ the\ algebraic\ terms\ match,\\We\ can\ take\ the\ LCM\ of\ their\ co-efficients;\\As\ the\ co-efficients\ of\ the\ x-terms\ are\ 5,7\ respectively;\\Their\ LCM\ is\ 35.[/tex]
[tex]Hence,\\7(5x+7y)=7(17)\\-5(7x+5y)=-5(19)\\Hence,\\35x+49y=119\\-35x-25y=-95\\Hence,\\Adding\ the\ two\ equations\ we\ have:\\(35x+49y)+(-35x-25y)=(119)+(-95)\\(35x-35x)+(49y-25y)=119-95\\24y=24\\y=\frac{24}{24}=1[/tex]
[tex]Now,\\Lets\ consider\ the\ First\ Equation:\\5x+7y=17\\Substituting\ y=1,\\5x+7*1=17\\5x+7=17\\5x=17-7\\5x=10\\x=\frac{10}{5}=2\\\\Together,\\x=2.\ y=1[/tex]

The shadow cast by a lampshade has a boundary in the shape of a hyperbola defined by the equation StartFraction (y minus 3) squared Over 2 EndFraction minus StartFraction x squared Over 1 EndFraction = 1. What could the center of the hyperbola represent?
the location of the light bulb
the bottom of the lampshade
the top of the lampshade
a vertex of the shadow
Answer:
A THE LOCATION OF THE LIGHT BULB
I got this right on the assignment
Step-by-step explanation:
The centre of the hyperbola represent will represent the location of the light bulb.
What is the centre of a hyperbola?The centre of a hyperbola is the midpoint of the line segment joining its foci. The transverse axis is the line segment that contains the centre of the hyperbola and whose endpoints are the two vertices of the hyperbola.
As we know that the centre of a hyperbola is the midpoint of the line segment joining its foci. Now, if we plot the hyperbola with equation
[tex]\dfrac{(y-3)^2}{2}-\dfrac{x^2}{1}=1[/tex]
The hyperbola will look like the one given in the below image, further if draw two lines to know the centre of the hyperbola, we will find that the centre of the hyperbola will lie at coordinate (0,3).
Further, the centre of the hyperbola represents the light bulb while the hyperbolas will represent the shadow cast by the lampshade.
Hence, the centre of the hyperbola represent will represent the location of the light bulb.

Answer:
y = 4x - 3
Step-by-step explanation:
The equation for a line is y = mx +c
We need to find m which is the gradient:
To do this pick any two coordinates on the line:
(1, 1) and (2, 5)
Next divide the difference of the y coordinates by the difference of the x coordinates:
5 - 1 / 2 - 1
= 4/1 = 4
so our gradient is 4
We'd write that as y = 4x + c
Next we need to find c which is the y-intercept
To do this just simply look for where the line crosses the y-axis
This is -3
So we'd write that as y = 4x - 3
Hope this helps :)
