Stacy would spend $52.50 in buying the tickets. Step-by-step explanation: The total cost of tickets brought can be calculated by the formula c=3.5 t. Here t represents the number of tickets . It is given Stacy bought 15 tickets ,hence t=15. The total cost of tickets Stacy bought c= 3.5(15) Or c=52.5 Stacy would spend$52.50 in buying the tickets.

The data set shows the number of boxes the 10 families living on Willow Avenue buy, on average, every year. {2, 3, 2, 2, 0, 5, 2, 1, 1, 3} Does this data have negative, positive, or zero skew? ## Answer: This data set has zero skew as it is symmetric. ## Step-by-step explanation: We know that the symmetry exist in a data when the mean, median and mode of the data is same. i.e. we are given a set of data as: {2, 3, 2, 2, 0, 5, 2, 1, 1, 3} • On arranging the data in increasing order we get : 0 1 1 2 2 2 2 3 3 5 Hence, the value that occur in the middle is: 2 Hence, we have Median=2 • Also, the mean is calculated as follows: Hence, Mean=2.1 • Also, the mode of the data is the most frequently occurring data point in the set. Here 2 occurs most number of times i.e. 4 times and hence we have: Mode=2 Now, as the Mean, Median and Mode of the data are approximately same. Hence, we get the data is symmetric and hence has a zero skew.

### Find the value of "a" for which the graph of the first equation is perpendicular to the graph of the second equation. 1) equation : y=a/3x-6 2) equation 4x+2y=6 Their is the same problems but different equation.1) 3y+ax=8 2)3/4x+2

Perpendicular lines will have negative reciprocal slopes. Example : if u r given a slope of 1/3, to find the negative reciprocal, flip the slope and change the sign. So the negative reciprocal of 1/3 is -3/1 or just -3. So slope 1/3 and slope -3 are perpendicular.
==================
equation 2 :
4x + 2y = 6
2y = -4x + 6
y = -2x + 3...the slope here is -2....a perpendicular line will have a slope of 1/2.

y = (a/3)x - 6......so we have to make a/3 = 1/2......1.5/3 = 1/2
so a = 1.5
===================
eq. 2 : 3/4x + 2
not sure what the entire equation is.....but it looks to have a slope of 3/4. That means a perpendicular line will have a slope of -4/3.

3y + ax = 9
3y = -ax + 9
y = (-a/3)x + 3.....therefore, a has to be 4

QUESTION POSTED AT 19/02/2020 - 01:34 PM

### Thomas buys a cardboard sheet that is 12 by 8 inches. Create an equation for this situation, find the zeros, and sketch the function. What is the size of the cutout he needs to make so that he can fit the maximum amount of food in the box? If Thomas wants a volume of 12 cubic inches, what size does the cutout need to be? What would be the dimensions of this box? Using complete sentences, explain the connection between the cutout and the volume of the box. Design an equation that would work for any cardboard sheet length, q, and width, p.

For the answer to the question above,

1. If we let x as the side of the square cut-out, the formula for the capacity (volume) of the food dish is:
V = (12 - 2x)(8 - 2x)(x)
V = 96x - 40x^2 + 4x^3
To find the zeros, we equate the equation to 0, so, the values of x that would result to zero would be:
x = 0, 6, 4

2. To get the value of x to obtain the maximum capacity, we differentiate the equation, equate it to zero, and solve for x.
dV/dx = 96 - 80x + 12x^2 = 0
x = 5.10, 1.57
The value of x that would give the maximum capacity is x = 1.57

3. If the volume of the box is 12, then the value of x can be solved using:
12 = 96x - 40x^2 + 4x^3
x = 0.13, 6.22, 3.65
The permissible value of x is 0.13 and 3.65

4. Increasing the cutout of the box increases the volume until its dimension reaches 1.57. After that, the value of the volume decreases it reaches 4.

5. V = (q -2x) (p - 2x) (x)
