Answer:
The maximum revenue Luci can make selling cookies in one day is $2,000.
The price she should sell the cookies to make the maximum revenue is $1
Step-by-step explanation:
W are given the following in the question:
x= -2000 p + 4000 ................ (1)
Therefore, revenue can be obtained as follows:
Revenue = R = px = p(-2000 p + 4000) = -2000p^2 + 4000p ........... (2)
Differentiating equation (2) with respect to p and equate to 0, we have:
dR / dp = -4000p + 4000 = 0 ................. (3)
From equation (3), we solve for p as follows:
-4000p + 4000 = 0
4000 = 4000p
p = 4000 / 4000
p = 1
Therefore, this implies that the price she should sell the cookies to make the maximum revenue is $1.
Substituting p = 1 into (2), we have:
Revenue = (-2000 * 1^2) + (4000 * 1)
Revenue = -2000 + 4000
Revenue = 2000
Therefore, this implies that the maximum revenue Luci can make selling cookies in one day is $2,000.

Elena's distances and times for a training run are given by the equation , where represents distance in miles and represents time in minutes. Who ran faster during the training run?
Answer:
Elena's run for 1.17 miles in ten minutes
Step-by-step explanation:
From the question
y = 8.5 x ; where x is Distance in miles, and y is time in minutes
and y= 10 minutes
thus on substituting the respected values we get
10 = 8.5 x
⇒ x = [tex]\frac{10}{8.5}[/tex] = 1.17 miles
Therefore Elena's run for 1.17 miles in ten minutes

It is a weak positive correlation, and it is not likely causal.
It is a weak positive correlation, and it is likely causal.
It is a strong positive correlation,and it is not likely causal.
It is a strong positive correlation, and it is likely causal.
Answer: It is a strong positive correlation,and it is not likely causal.
Step-by-step explanation: Correlation Coefficient value is used to determine the strength of linear relationship between two variables. The value ranges from - 1 to +1.with negative values depicting a negative relationship and positive values showing positive relationship. Value of 0 implies that, no relationship exists. The closer the correlation Coefficient value is to +1 or - 1, the greater the strength of the relationship between them. Also correlation does not mean causation. Hence, a correlation coefficient of 0.74 depicts a strong positive relationship. However it doesn't imply causation.
The given correlation is strong positive correlation,and it is not likely causal.
We have given that,

A survey was conducted of 880 college students attending the same university. They were offered a list of 10 different internet service providers and were asked to select the one they prefer. Can a service provider receiving only 89 votes come out on top?
Answer: Yes
Step-by-step explanation:
From the question, we are informed that a survey was conducted of 880 college students attending the same university and that they were offered a list of 10 different internet service providers and were asked to select the one they prefer.
Basee on this information, if everyone selected equal numbers, each service provider will get (880 / 10 = 88 students). In this case, if someone has 89 votes, this means that another person will get 87 votes while the remaining 8 service providers gets 88 students each. Therefore, the device provider with 89 votes can come out on top.

find the measure of the indicated angle ? no l
The interior angle of any triangle sum to 180° in measure, so that angle ACB has measure
m∠ACB = 180° - 67° - 35° = 78°
Angles ACB and BCD are supplementary because they occur on the same ray AD, which means they also sum to 180° in measure. Then angle BCD has measure
m∠BCD = 180° - 78° = 102°
Answer:
102 degrees
Step-by-step explanation:
for this problem, add the angles given to 180 degrees to find the remaining angle ACB in the triangle. Once you have that angle, you can subtract it from 180 degrees to find BCD, because side ACD is straight. By adding Angle CAB (67 degrees) and Angle ABC (35 degrees), you end up with the missing 98 degrees to reach 180 degrees. thus, when subtracting to find BCD on the straight of ACD, a value of 102 degrees remains for Angle BCD

Answer:
1. x = 6 cm
2. The coordinates of the x-intercept are (-15.798879, 0) and (8.177004, 0)
b) The maximum value of is y is approximately 459.874
The value of 'x' for which the maximum occurs is x is -3.8109375
c) 'k' is approximately -15.63748 or 'k' is approximately 8.0156
Step-by-step explanation:
1. The area of rectangle ABCD - Area of triangle ABP = 114 cm²
Therefore, we have;
The area of rectangle ABCD = (2·x - 3)·(3·x + 1)
∴ The area of rectangle ABCD = 6·x² + 2·x - 9·x - 3 = 6·x² - 7·x - 3
The area of triangle ABP = 1/2 × (3·x + 1)·x = 3·x²/2 + x/2
The area of rectangle ABCD - Area of triangle ABP = 6·x² - 7·x - 3 - 3·x²/2 - x/2
6·x² - 7·x - 3 - 3·x²/2 + x/2 = 9·x²/2 - 13·x/2 - 3 = 114
9·x²/2 - 15·x/2 - 3 = 114
9·x² - 15·x - 6 - 228 = 0
9·x² - 15·x - 234 = 0
x = (15 ± √((-15)² - 4 × 9 × (-234)))/(2 × 9) = (15 ± 93)/18
∴ x = 6 or x = -13/3
Given that x is a natural number, we have that x = 6 cm
2. The given equation is 'y = -3.2·x² - 24.39·x + 413.4'
Therefore, we have;
The x-intercept are the values of 'x', where the value of 'y' is 0
Therefore, we have, at the x-intercept;
y = 0 = -3.2·x² - 24.39·x + 413.4
By the quadratic formula, we have;
x = (24.39 ± (√((-24.39)² - 4×(-3.2)×413.4)))/(2 × (-3.2))
x ≈ -15.798879 or x ≈ 8.177004
The coordinates of the x-intercept are;
(-15.798879, 0) and (8.177004, 0)
b) The maximum is given at dy/dx = 0
Therefore, at the maximum point, we have;
dy/dx = d(-3.2·x² - 24.39·x + 413.4)/dx = -6.4·x - 24.39 = 0
dy/dx = -6.4·x - 24.39 = 0
∴ x = 24.39/(-6.4) = -3.8109375
x = -3.8109375 at the maximum point
At the maximum point, we have;
y = -3.2·x² - 24.39·x + 413.4 = -3.2·(-3.8109375)² - 24.39·(-3.8109375) + 413.4 ≈ 459.874
y ≈ 459.874
Therefore, the maximum value of 'y' is given as follows
[tex]y_{max}[/tex] ≈ 459.874
The value of 'x' for which the maximum occurs is x = -3.8109375
c) The coordinate of the point is (12.3, k), therefore, we have;
y = -3.2·x² - 24.39·x + 413.4
When y = 12.3, therefore, -3.2·x² - 24.39·x + 413.4 = 12.3
-3.2·x² - 24.39·x + 413.4 = 12.3
-3.2·x² - 24.39·x + 413.4 - 12.3 = -3.2·x² - 24.39·x + 401.1 = 0
By the quadratic formula, we have;
x = (24.39 ± √((-24.39)² - 4×(-3.2)×401.1))/(2 × (-3.2))
x ≈ -15.63748 or x ≈ 8.015600
Therefore, k ≈ -15.63748 or k ≈ 8.015600
