How much more would the value of y be on the graph than its value
in the table when x = 12? (1 point)
Answer:
180
Step-by-step explanation:
From the table :
Slope :
m = (y2 - y1) / (x2 - x1)
m = (100 - 80) / (5 - 4)
m = 20 / 1
m = 20
y = 20x
Hence, when, x = 12
y = 20 * 12
y = 240
From the graph:
Slope :
m = (y2 - y1) / (x2 - x1)
m = (280 - 70) / (8 - 2)
m = 210 / 6
m = 35
y = 35x
When x = 12
Graph :
y = 35 * 12
y = 420
Difference :
420 - 240
= 180

21.6 turn into 2120.9 turn into 2119.4 turn into 1918.5 turn into 19Add up those values: 21+21+19+19 = 80
-------------------
Another estimate you could do is to round everything to 20, since we're close to this value. Having four copies of 20 added leads to 20+20+20+20 = 80
So they rode a total estimated amount of 80 miles
--------------------
The actual total is: 21.6+20.9+19.4+18.5 = 80.4 miles, which isn't too far off from 80.

Edg told me
a trader bought some eggs at 64 per dozen and sold 2/3 of them at 240/= per tray and the other 1/3 at 225/= per tray.In so doing she made a profit of 450/=.given 1 tray holds 30 eggs and 1 dozen 12 eggs determine the number of eggs she bought.
Note that the number of eggs the above-described trader bought is 180 eggs. This is solved using simple arithmetic.
What is the justification for the above response?
Let no. of the eggs be x, then
Money the trader paid for eggs = 64/12x = 16/3x
The money the trader got from
Seling two third eggs =2/3x*240/30
=16/3x
Money get from one third= x/3*225/30
=5/2
Profit= [16/3x+5/2x] - 16/3x
5/2x = 450
x =450*2/5
=180
Therefore, the number of eggs that the trader bought is 180.

Which method can you use to prove that the triangles are congruent?
Answer:
The simplest way to prove that triangles are congruent is to prove that all three sides of the triangle are congruent. When all the sides of two triangles are congruent, the angles of those triangles must also be congruent. This method is called side-side-side, or SSS for short.

16 In a flower fertilisation experiment, the
number of pink flowers grown is twice that
of red flowers. The number of white flowers
grown is 3 more than that of red flowers.
The number of white flowers grown is
37 fewer than that of pink flowers. Find the
total number of flowers grown.
Answer:
The total number of flowers grown is 163.
Step-by-step explanation:
Since in a flower fertilization experiment, the number of pink flowers grown is twice that of red flowers, and the number of white flowers grown is 3 more than that of red flowers, the number of white flowers grown is 37 fewer than that of pink flowers, to find the total number of flowers grown the following calculation must be performed:
P = 2R
W = R + 3
W = P - 37
W = W
R + 3 = 2R - 37
R + 3 + 37 = 2R
40 = 2R - R
40 = R
P = 2 x 40 = 80
R = 40
W = 40 + 3 = 43
80 + 40 + 43 = X
163 = X
Therefore, the total number of flowers grown is 163.

The length of a rectangular lot is 6 feet less than 3 times its
width. Its area is 222 square feet.
Its width is
feet and its length is
feet.
Answer:
Its width is 9.66 feet and length is 22.98 feet.
Step-by-step explanation:
Let l is length and b is width of a rectangular lot.
Length, l = (3b-6) feet
The area of the lot is 222 sq feet.
The area of a rectangle is given by :
[tex]A=lb\\\\222=(3b-6)b\\\\222=3b^2-6b[/tex]
It is a quadratic equation. The solution of the above equation is given by :
b = 9.66 feet and -7.66 feet
Neglecting negative answer, the width of the lot is 9.66 feet.
Length, l = (3(9.66)-6) = 22.98 feet
Hence, its width is 9.66 feet and length is 22.98 feet.

Answer:
D) y=-5/2x; y=-20
Step-by-step explanation:
If y varies directly with x, then y=kx where k is our proportionality constant
Therefore, since y=-5 when x=2, we have -5=k(2) where k=-5/2
This means that when x=8, y=(-5/2)(8)=-20, making choice D correct

All else being equal, if you cut the sample size in half, how does this affect the margin of error when using the sample

O The margin of error is multiplied by a
O The margin of error is multiplied by 0.5.
O The margin of error is multiplied by 2.
Answer:
The margin of error is multiplied by 4.
Step-by-step explanation:
Margin of error is:
[tex]M = \frac{zs}{\sqrt{n}}[/tex]
In which z is related to the confidence level, s is elated to the standard deviation and n is the sample size.
From this, we have that the standard deviation is inversely proportional to the square root of the sample size.
If you cut the sample size in half:
The margin of error is inversely proportional to the square root of the sample size, so if you cut the sample size by [tex]\frac{1}{2}[/tex], the margin of error will be multiplied by [tex]2^2 = 4[/tex]
So
The margin of error is multiplied by 4.
