1) Since this is a line of best fit, actually we are going to find an approximation for that.
2) Locating two points along the line, we've got (1,30) and (7,60) so let's find the rate of change:
\(m=\frac{y_2-y_1}{x_2-x_1}=\frac{60-30}{7-1}=\frac{30}{6}=5\)So, the rate of change relative to the scatter plot is 5

what is the property of 3x(5x7)=(3x5)7
The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.
In the equation you provided: 3x(5x7) = (3x5)7
The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

What is the combination in maths?Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. You can choose the components of combos in any order.
If there are 2 sandwiches, 2 drinks, and 2 desserts to choose from and the lunch special is a sandwich, drink, and dessert.
The total choices are 3 in that 2 options for every choice are available.
Thus total combination can be made = 2³
total combination can be made = 8
Therefore, the total number of possible lunch specials is 8.

Mrs. Smith made 6 ¼ dozen cookies for the birthday party. At the end of the party, there were 3 ½ dozen cookies left. How many cookies did the guests eat?
The guests in the birthday party ate 33 cookies.
How many cookies did the guests eat?We know that Mrs. Smith made 6 1/4 dozen cookies and there were 3 1/2 dozen cookies left.
Let's first convert these fractions to a common denominator of 4, so we can easily subtract them.
6 1/4 dozen = 25/4 dozen
3 1/2 dozen = 14/4 dozen
Now we can subtract the number of cookies that were left from the number of cookies that were made:
25/4 - 14/4 = 11/4 dozen
To find out how many cookies this represents, we need to multiply by the number of cookies in one dozen.
There are 12 cookies in one dozen, so:
11/4 x 12 = 33
Therefore, the guests ate 33 cookies.

For the function \(A(t)=4000e^0^.^0^4^t\) the value of A'(8) is $220 and the value of \(A'(t)=160e^0^.^0^4^t\)
The given function is \(A(t)=4000e^0^.^0^4^t\) gives the balance after t years.
The initial investment is 8000
4% is the compounded interest.
Now differentiate with respect to t
\(A'(t)=0.04(4000)e^0^.^0^4^t\)
\(A'(t)=160e^0^.^0^4^t\)
Now let us find the value of A'(8)
Plug in t as 8
\(A'(8)=160e^0^.^0^4^(^8^)\)
A'(8)=220.3
Hence, the value of A'(8) is $220 and the value of \(A'(t)=160e^0^.^0^4^t\)

It is between 23 and 32.
It is also a multiple of 5.
What is Lucas' number?

The two equations that represent the remaining angle relationships are
x = 2(y + z) - 20 and x = 3z - 20
Writing equationsFrom the question, we are to determine the two equations that represent the remaining angle relationships
From the given information, we have that
x is the largest angle, y is the next largest angle and z is the smallest angle
Also, from the information,
"The measure of the largest angle is 20 degrees less than twice the sum of the measure of the other two angles"
That is,
x = 2(y + z) - 20
and
"The largest angle is 3 times the smaller angle minus 20 degrees"
x = 3z - 20
Hence, the two equations that represent the remaining angle relationships are x = 2(y + z) - 20 and x = 3z - 20

Mr. Javier purchased a number of pencils for ₱180 and sold all except 6 at a profit of ₱2 per pencil. With the total amount received, he could buy 30 more items than before. Find the number of items he bought and the cost of each in pesos
Answer:
36 pencils
\(Cost = 0.2\)
Step-by-step explanation:
Given
Cost Price = 180
Represent the number of items by x
This implies that the cost of each item is \(\frac{x}{180}\)
\(Selling\ Price = Cost + Profit\)
\(Selling\ Price = \frac{x}{180} + 2\)
Since all but 6 items were sold, the total selling price is:
\(Total = (x - 6)(\frac{x}{180} + 2)\)
This amount can be used to buy 30 more items.
So, we have:
\((x - 6)(\frac{x}{180} + 2) = x + 30\)
Multiply both sides by 180
\(180 * (x - 6)(\frac{x}{180} + 2) =180(x + 30)\)
\((x - 6)(x + 360) = 180x + 5400\)
Expand brackets
\(x\² + 360x - 6x - 2160 = 180x + 5400\)
\(x\² + 354x - 2160 = 180x + 5400\)
Equate to 0
\(x\² + 354x - 180x - 2160 - 5400 = 0\)
\(x\² + 174x - 7560 = 0\)
Expand
\(x\² + 210x - 36x - 7560 = 0\)
\(x(x + 210) - 36(x + 210) = 0\)
\((x - 36)(x + 210) = 0\)
\(x - 36 = 0\) or \(x + 210 = 0\)
\(x = 36\) or \(x = -210\)
Since, number of items can't be negative, we have to discard x = -210.
Hence:
\(x = 36\)
We can then conclude that, Mr. Javier purchased 36 pencils
Recall that
\(Cost = \frac{x}{180}\)
\(Cost = \frac{36}{180}\)
\(Cost = 0.2\)
