0.550×$60 = $33
$60- $33= $27.00
Therefore, the answer is $27
Answer:
Step-by-step explanation:
<u>This is an AP with:</u>
- The first term a₁ = 12
- Common difference d = 3
- Number of terms n = 40
<u>Number of the seats:</u>
- Sₙ = 1/2*n(a₁ + aₙ) = 1/2n(2a₁ + (n - 1)d)
- S₄₀ = 1/2*40(12*2 + 39*3) = 2820 seats
<u>Formula of nth term:</u>
- aₙ = a₁ + (n - 1)d
- aₙ = 12 + (n - 1)*3 = 12 + 3n - 3 = 3n + 9
- aₙ = 3n + 9
<h3>a. slope =

Scatter plot shows the relationship between data
We can use Regression to make lines on the chart or you can also make lines with the principle as close as possible to all points
Regression
Because data is in the form of numbers from the hand span length and height of each of students. not displayed clearly, then we make a line directly by making points on the graph above and below the line as much as possible to be balanced
We specify 2 points that are crossed by a line, for example:
(6.45) and (8.60)
slope (m) = change in y / change in x
Slope has a positive value, and shows a positive correlation where the tendency of the number rises simultaneously, or can be concluded:
<em>tall students will have the long hand span length too</em>

Answer: Yes. The answer is: [C]: "1 " .
______________________________________________
Explanation:
______________________________________________
The equation for a line, in "slope-intercept format" , is:
______________________________________________
→ y = mx + b ;
______________________________________________
in which "b" = the y- intercept; or the value of 'x' when "y = 0" ;
"m" = the slope; which is also the coefficient of "x".
____________________________________________________
In "slope-intercept format", the "y" remains isolated on the left-hand side of the equation, with no "coefficient" (other than the "implied coefficient" of "1").
__________________________________________________________
So, if the two particular lines are parallel, and we know that the slope is "1" for EACH line; (that is, "m = 1" for each line); then the PRODUCT of the two slopes is:
____________________________________________________________
→ m² = m * m = 1² = 1 * 1 = 1 .
____________________________________________________________
→ The answer is: Answer choice: [C]: "1" .

The vertex of the absolute value function f(x) = |x| is (0,0).
What about <span>f(x)=-|x+2|-2? This can be re-written as f(x) = -|x-(-2)| -2.
Three things happen here: first, the graph of f(x) = |x| must be inverted, so that it opens down instead of up; second, the resulting graph must be translated 2 units to the left; and third, the resulting graph must be translated 2 units down.
