Determine whether there is a good line of best fit for the given graph. Then, if there is a good line of best fit, determine if the correlation is
positive or negative.
Answers
Answer:
The line's slope equals the difference between points' y-coordinates divided by the difference between their x-coordinates. Select any two points on the line of best fit. These points may or may not be actual scatter points on the graph. Subtract the first point's y-coordinate from the second point's y-coordinate.

Which is larger? The measure of a central angle of a circle that intercepts a 68 degree arc of the measure of an inscribed angle of a circle that intercepts a 68 degree arc. Explain
Answers
Answer:
The measure of a central angle of a circle that intercepts a 68° arc
Step-by-step explanation:
Recall the inscribed angle theorems:
Measure of central angle = measure of intercepted arc
Measure of inscribed angle = ½(measure of intercepted arc)
Therefore,
The measure of a central angle that intercepts a 68° arc = 68°
Measure of an inscribed angle of a circle that intercepts a 68° arc = ½(68°) = 34°
Therefore, the larger would be:
The measure of a central angle of a circle that intercepts a 68° arc

Bamboo plants grow rapidly. A bamboo plant is 140 inches tall. Tomorrow it will be 154 inches tall, the next day it will be 168 inches tall, and on the next day it will be 182 inches tall. Write a rule to represent the height of the bamboo plant as an arithmetic sequence. How tall will the plant be in 16 days?
Answers
Answer:
350 inches
Step-by-step explanation:
aₙ = a₀ + d(n-1)
d = common difference
a(16 days) = 140 + 14(15)
= 140 + 210
= 350

Consider the graph y = 2x2 + 7x + 6.
a) The graph of this equation is called a parabola. Does this parabola open
upward or downward? How do you know?
b) What is the y-intercept? How do you know?
c) Find the x-intercepts. Show relevant process.
Answers
Answer:
a) Parabola opens up
b) 6
c) -3/2 and -2
Step-by-step explanation:
a) The general form of a parabolic graph is;
y = ax^2 + bx + c
if a is positive, it faces up, if negative, it opens down
Since a = 2 here, it is positive and thus the parabola faces or opens up
b) The y-intercept is simply the c term
the value here is 6
The y intercept is obtained when the x value is zero
So by simply setting the x value to zero, we can easily get the y value since x is zero at that point
c) The x-intercepts refer to the roots of the equation
By solving the quadratic equation i.e substituting 0 for y, we can get the two x values as follows;
2x^2 + 7x + 6 = 0
2x^2 + 4x + 3x + 6 = 0
2x(x + 2) + 3(x + 2) = 0
(2x + 3)(x + 2) = 0
2x + 3 = 0 or x + 2 = 0
2x = -3 or x = -2
x = -3/2 or x = -2
Studies have shown that 400 people attend a high school basketball game when the admission price is
$3.00. In the championship game, admission prices will increase. For every $0.25 increase, 20 fewer
people will attend. At what ticket price will the revenue be maximized?
Answers
Answer:
Let x=number of $0.25 increases, so the equation for revenue=price*number of tickets or people) becomes
Revenue=($3.00+$0.25x)(400-20x)
where ($3.00+$0.25x) :increase in price
and
(400-10x) : decrease in number of people
Expanding Revenue
Revenue[R]=1200-60x+100x-5x²:1200+40x-5x²
Taking the derivative of R and set it equal to 0:
R'=0+40-10x=40-10x
we have
R'=0
40-10x=0
x=40/10
x=4
So the ticket price is $3.00+$0.25*4=$4
The number of people will attend is 400-20*4=$320
At $320 ticket price will the revenue be maximized.
Step-by-step explanation:
A $320 ticket price will the revenue be maximized
