The line of best fit is y = 1.383x - 1.526 after calculating using the table, and option (c) y = 1.383x - 1.526 is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
As we know, the regression line is a graph that illustrates the pattern of a group of statistics. In other words, it shows the data's best pattern.
We have data shown in the table:
We can find the line of best fit by the formula.
Let y = mx + c
m is the slope of the line of best fit and the y-intercept is c.
After calculating:
m = 1.383
c = -1.526
y = 1.383x - 1.526
Thus, the line of best fit is y = 1.383x - 1.526 after calculating using the table, and option (c) y = 1.383x - 1.526 is correct.

Answer:
picture from Goldbach's conjecture.
Step-by-step explanation:
Goldbach's conjecture is one of the oldest and best-known unsolved problems in number theory and all of mathematics. It states:
Every even integer greater than 2 is the sum of two primes.
The conjecture has been shown to hold for all integers less than 4 × 10^18, but remains unproven despite considerable effort.
So on the red and blue axes you see primes. The list of black numbers are even numbers.
What is the rate of change of e=3h+200
Answer:
3
Step-by-step explanation:
"Rate of change" is the real-world problem way of saying "slope."
So whenever a question asks you to find "rate of change", simply look for the slope.
y = mx + b
e = 3h + 200
mx = slope/rate of change
So, 3 would be your answer.
A free cable sparkling juice calls for 1 1/2 quarters of sparkling water and 3/4 course with grape juice how many sparkling how much sparkling water would you need to mix with 9 quarts of grape juice
Answer: 18 quarts
Step-by-step explanation:
As per given,
Quantity of sparkling juice is proportional to quantity of course with grape juice.
Given: A free cable sparkling juice calls for [tex]1\dfrac12[/tex] quarters of sparkling water and [tex]\dfrac34[/tex] course with grape juice .
Let x be the quantity of sparkling water need to mix with 9 quarts of grape juice.
then, by equation of direct proportion , we have
[tex]\dfrac{1\dfrac12}{\dfrac34}=\dfrac{x}{9}\\\\\Rightarrow\dfrac{\dfrac{3}{2}}{\dfrac{3}{4}}=\dfrac{x}{9}\\\\\Rightarrow\ \dfrac21=\dfrac{x}{9}\\\\\Rightarrow\ x=9\times2\\\\\Rightarrow\ x=18[/tex]
Hence, the quantity of sparkling water need to mix with 9 quarts of grape juice = 18 quarts

Answer: C) Neither positive nor negative -- the sum is zero
Adding any positive number to its negative counterpart always leads to 0.
We could come up with a story problem where a person has $37 in their bank account, and then they take out $37 which is represented with the negative number. This leads the balance to become 37+(-37) = 37-37 = 0 dollars.

A store has apples on sale for $15.00 for 6 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $60.00? Complete the explanation.
The cost per pound of the apples on sale is $15.00
.
You can buy __ pounds of apples for $60.00.
Since 1 pound = 16 ounces, so there are about __ apples in each pound.
You can buy approximately __apples for $60.00.
Answer:
24 pounds of apples for $60
about 3 apples per pound
about 72 apples for $60
Step-by-step explanation:
$15 times 4 = $60, therefore 6 pounds times 4 = 24 pounds
5 out of 16 ounces equals about 3 apples per pound
24 pounds, with 3 apples in each pound, equals 72
$2.99 toy ; 30% discount
Answer:
is 2.99 the price before or after the discount
Answer:
2.69 i think
Step-by-step explanation:
Use the given substitution and the chain rule to find
dy/dx
y=cos (6x - 5), u = 6x-5
Substituting u = 6x - 5, you write
y = cos(u)
Then differentiating with the chain rule gives
dy/dx = dy/du • du/dx
We have
dy/du = -sin(u)
du/dx = 6
so
dy/dx = -6 sin(u) = -6 sin(6x - 5)

Answer:
43-5= 38 (subtract the y-intercept from the last number to see how many stamps were sold over the past two months)
38/2= 19 (the number of stamps sold over 2 months divided by how many months it took for those stamps to be sold)
19 is what goes in the box
The cost for an order of 100 kilograms of steel bars is $230. The cost for an order of 150 kilograms of steel bars is $320. Write an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x). Show or explain how you found your equation.
Answer:
y = 9x/5 + 50
Step-by-step explanation:
We are represent the information as coordinate (x,y)
If the cost for an order of 100 kilograms of steel bars is $230, this is expressed as (100, 230)
Also if the cost for an order of 150 kilograms of steel bars is $320, this is expressed as;
(150, 320)
Find the equation of a line passing through the points. The standard form of the equation is expressed as y = mx+c
m is the slope
c is the intercept
Get the slope;
m = y2-y1/x2-x1
m = 320-230/150-100
m = 90/50
m = 9/5
Get the y-intercept by substituting m = 9/5 and any point say (100, 230) into the expression y = mx+c
230 = 9/5(100)+c
230 = 9(20)+c
230 = 180 + c
c = 230-180
c = 50
Get the required equation
y = mx+c
y = 9/5 x + 50
Hence an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x) is y = 9x/5 + 50

After school, Diana had a science club meeting for 1 hour and 20 minutes, followed by a choir rehearsal that lasted for 1 hour and 35 minutes. If Diana got out of school at 1:40 P.M., what time did the choir rehearsal end?
Answer:
3:15PM
Step-by-step explanation:
If If Diana got out of school at 1:40 P.M, this and spent 1 hour 35 minutes at the rehearsal, to know the time that the choir rehearsal ends, we will have to add the time spent at rehearsal to the time he got out of school;
1:40 P.M + (1hr 35 minutes)
1:40 P.M + 1 hr = 2:40PM
2:40PM + 35mintes = 2:40PM + (20mintes) +15 minutes
[2:40PM + (20mintes)] +15 minutes = 3:00pm + 15 minutes
3:00pm + 15 minutes = 3:15PM
Hence the choir rehearsal ends at 3:15PM

Answer:
25/3
Step-by-step explanation:
Set the equations equal to each other since the lines are parallel.
(x+20)=(4x-5)
-x +5 -x +5
25/3 = 3x/3
x = 25/3
5x+4y=116 10x+6y=204 solve for x and y
Answer:
x = 12
y = 14
Step-by-step explanation:
5x + 4y = 116
5 x 12 = 60
4 x 14 = 56
60 + 56 = 116
10x + 6y = 204
10 x 12 = 120
6 x 14 = 84
120 + 84 = 204
-------------------------------------------
Here's how I found x and y:
10x + 6y = 204 can be divided by 2
5x + 3y = 102
Then I took 116 and subtracted 116 given the difference
in y.
116 - 102 = 14
So y = 14 and then I sovled for x:
5x + 56 = 116
116 - 56 = 60
60/5 = 12
10x + 84 = 204
204 - 84 = 120
120/10 = 12
For a fairground ride the maximum weight of a person is 100kg to the nearest kg.
What is the maximum a person can weigh to go on the ride safely
Answer:
The maximum a person can weigh to go on the ride safely is 100.5 kg
Step-by-step explanation:
The specification for the maximum weight of each person that goes on the ride = 100 kg
Therefore, given that the maximum possible error of a measurement is equal to 1/2 multiplied by the unit of measurement, we have that the specified maximum weight, [tex]W_{max}[/tex], can be written as follows;
[tex]W_{max}[/tex] = (100 ± 0.5) kg, which gives the maximum a person can weigh to go on the ride safely as 100 kg + 0.5 kg = 100.5 kg
