The maximum cardinality of S is 20.
How to find the maximum cardinality ?To increase the number of subsets within S, our goal must be to find as many non-empty subset intersections as possible. This is achieved by constructing subsets that possess only one shared element. In this particular case, any two sets contained in the collection will include the element 2000 in their intersection causing it to become a valid subset.
Now, we shall investigate whether an additional subset can be added to S. If an extension exists without including 2000, its intersection with the previous 20 subsets would negligibly have no common elements and would hence not be regarded as a valid subset for addition into S.
As a result, a total of 20 subsets represent maximum cardinality for set S per these conditions.

The engine in a ice cream truck has a power curve approximated by Y=-X^2/5000 + 19x/23 -26
X is the RPM, Y is the horsepower generated (notice the a and b values are fractions)
What is the maximum horsepower? Round your answer to three decimal places.
The maximum horsepower of the ice cream truck engine is 827.025.
How to find the maximum horsepower?For quadratic equation y = ax² + bx + c, the maximum value of y is given by:
y(max) = c- b²/4a
Since the horsepower generated by the ice cream truck engine power curve is approximated by Y = -X²/5000 + 19x/23 -26
In this case, a = -1/5000, b = 19/23 and c = -26
Thus, the maximum horsepower will be:
maximum horsepower = -26 - (19/23)²/[4*(-1/5000)]
maximum horsepower = 827.025 horsepower

Vase A has height 10 cm. Vase B has height 15 cm. The difference between the volume of vase A and the volume of vase B is 1197 cm' Calculate the volume of vase A
The volume of vase A is given as follows:
504 cm³.
How to obtain the volume?The volume of vase A is obtained applying the proportions in the context of the problem.
Vase A has height 10 cm. Vase B has height 15 cm, hence the ratio between the heights is given as follows:
[tex]\frac{h_B}{h_A}[/tex] = 15/10
[tex]\frac{h_B}{h_A}[/tex] = 1.5.
The heights are given in units, while the volumes are given in cubic units, hence the rate between the volumes is given as follows:
[tex]\frac{vB}{vA}[/tex] = 1.5³
[tex]\frac{vB}{vA}[/tex]= 3.375
[tex]v_B = 3.375v_A[/tex].
The difference between the volume of vase A and the volume of vase B is 1197 cm³, hence:

Eliza plans on constructing a confidence interval for the slope of a regression line. She creates the residual plot shown to check the conditions for creating the interval. Which of the following conditions appear to be met based on the residual plot?
I.The true relationship between x
and y
is linear.
II.The standard deviation of y
is constant for different levels of x
.
III.The value of 0 is contained in the confidence interval.
Answer:
Based on the residual plot, we can check for the following conditions:
I. The true relationship between x and y is linear:
We can check this condition by looking at the pattern of the residuals in the plot. If the residuals are randomly scattered around zero, without any discernible pattern, then it suggests that the true relationship between x and y is linear. If there is a pattern in the residuals, then it suggests that the true relationship is not linear. Since we are not given a residual plot to examine, we cannot determine whether this condition is met.
II. The standard deviation of y is constant for different levels of x:
We can check this condition by looking at the spread of the residuals in the plot. If the spread of the residuals is roughly the same for all values of x, then it suggests that the standard deviation of y is constant for different levels of x. If the spread of the residuals increases or decreases as x increases, then it suggests that the standard deviation of y is not constant for different levels of x. From the residual plot, we cannot determine whether this condition is met.
III. The value of 0 is contained in the confidence interval:
This condition refers to the confidence interval for the slope of the regression line. If the confidence interval includes 0, then it suggests that the slope is not significantly different from 0 and there is no significant linear relationship between x and y. From the residual plot, we cannot determine whether this condition is met.
Therefore, based on the given information, we cannot determine which conditions appear to be met based on the residual plot.
Harvey’s pizzeria has three pizza sizes he wants to work out the outside measurement (circumference) of each size to work out how much cheese he will need for a stuff crust.
Match the correct circumference of each pizza using the diameter given.
Small –
Medium-
Large-
The circumference of the small pizza is approximately 47.1 cm, the circumference of the medium pizza is approximately 69.1 cm, and the circumference of the large pizza is approximately 94.2 cm.
The diameter is the distance across the widest part of a circle. To find the circumference of a circle, we use the formula C = πd, where C is the circumference, π is a mathematical constant (approximated as 3.14), and d is the diameter of the circle. Therefore, to find the circumference of each pizza size, we can simply plug in the given diameter into this formula.
For the small pizza with a diameter of 15 cm, the circumference can be calculated as follows:
C = πd
C = 3.14 x 15
C ≈ 47.1 cm
For the medium pizza with a diameter of 22 cm, the circumference can be calculated as follows:
C = πd
C = 3.14 x 22
C ≈ 69.1 cm
For the large pizza with a diameter of 30 cm, the circumference can be calculated as follows:
C = πd
C = 3.14 x 30

14. The distance between (x, 2) and (0, 6) is 5 units. Use the Distance Formula to determine
the value of x. Show all your work.
Answer:
The value of x is 3.
Step-by-step explanation:
The Distance Formula is:
d = √[(x2 - x1)² + (y2 - y1)²]
Using the given points, we have:
d = √[(0 - x)² + (6 - 2)²]
Simplifying inside the square root gives:
d = √[x² + 16]
We know that the distance between (x, 2) and (0, 6) is 5 units, so we can set up the equation:
5 = √[x² + 16]
Squaring both sides gives:
25 = x² + 16
Subtracting 16 from both sides gives:
9 = x²
Taking the square root of both sides gives:
x = ±3
Since we are looking for the value of x, we choose the positive solution:
x = 3
Therefore, the value of x is 3.
