The candy company's package can be modeled as a right circular cone with a height of 13 inches and a base diameter of 9 inches.
The circular base of the cone holds the chocolates, while the curved surface extends up to a point at the top. To calculate the surface area, we need to find the area of the circular base and the area of the curved surface. The formula for the area of a circle is pi times the radius squared, so the radius of the base is 4.5 inches.
The area of the base is pi times the radius squared, or approximately 63.62 square inches. The formula for the curved surface area of a cone is pi times the radius times the slant height, which is the square root of the height squared plus the base radius squared. Substituting the given values into the formula, the curved surface area is approximately 207.35 square inches. Thus, the approximate surface area of the package is the sum of the area of the base and the curved surface area, or approximately 271.97 square inches.

what is the mean of a game where one of the two possible outcome happens 20% of the time, with a value of 5, and the other possible outcome has a value of 10 g
The mean of the game is 9
To find the mean of a game with two possible outcomes, we need to multiply the value of each outcome by its probability and then add the results.
Let X be the random variable representing the outcome of the game. The first outcome has a value of 5 and a probability of 0.2, while the second outcome has a value of 10 and a probability of 0.8.
Thus, the expected value or mean of the game can be calculated as:
E(X) = (0.2 x 5) + (0.8 x 10)
= 1 + 8
= 9
Therefore, the mean of the game is 9

A) Larger variance increases both the standard error and measures of effect size.
B) Larger variance increases the standard error but decreases measures of effect size.
C) Larger variance decreases the standard error but increases measures of effect size.
D) Larger variance decreases both the standard error and measures of effect size.
The estimated standard error and measures of effect size such as r2 and Cohen's d larger variance increases the standard error but decreases measures of effect size. B.
Larger variance increases the standard error but decreases measures of effect size.
The standard error is a measure of how much the sample mean is likely to vary from the true population mean.
It is calculated as the standard deviation of the sample divided by the square root of the sample size.
If the sample variance is large, the standard deviation of the sample will also be large, resulting in a larger standard error.
Measures of effect size, such as r2 and Cohen's d, indicate the strength of the relationship between variables or the size of the difference between groups, respectively.
Larger sample variances indicate greater variability in the data, which can make it more difficult to detect significant effects.
This can result in smaller effect sizes, as the magnitude of the effect is reduced relative to the variability in the data.

What is quadratic equation?
A quadratic equation is a polynomial equation of degree two which can be written in the form: ax² + bx + c = 0, where x is the variable and a, b, and c are constants with 'a' not equal to 0. The term 'quadratic' comes from the Latin word 'quadratus', which means 'square'.
The equation given in the image is a quadratic equation in standard form, which means it is written in the form ax^2 + bx + c = 0, where a, b, and c are constants and x is the variable.
To determine which statement is true about this equation, we need to analyze its discriminant, which is given by the expression b^2 - 4ac. The discriminant tells us about the nature of the solutions of the quadratic equation.
If the discriminant is positive, then the equation has two distinct real roots.
If the discriminant is zero, then the equation has one real root (also known as a double root).
If the discriminant is negative, then the equation has two complex roots (conjugate pairs).
In the given equation, a = 3, b = -4, and c = 1. Substituting these values into the discriminant formula, we get:
b^2 - 4ac = (-4)^2 - 4(3)(1) = 16 - 12 = 4
Since the discriminant is positive, we know that the quadratic equation has two distinct real roots. Therefore, statement (A) is true.

Can a binomial probability distribution with p =.10 and n = 40 be approximated by the normal probability distribution? If so, what are the mean and standard deviation for the normal approximation?
The normal approximation for the given binomial distribution with p = 0.10 and n = 40 has a mean of 4 and a standard deviation of 1.93.
The binomial probability distribution can be approximated by the normal distribution when certain conditions are met, such as a large sample size and a probability of success not too close to 0 or 1.
In this case, n = 40 and p = 0.10. To determine if the normal approximation is appropriate, we can check if both np and n(1-p) are greater than or equal to 10
np = 40 x 0.10 = 4
n(1-p) = 40 x 0.90 = 36
Both np and n(1-p) are greater than or equal to 10, so the normal approximation is appropriate.
The mean of the binomial distribution is given by μ = np = 4, and the standard deviation is given by σ = √(np(1-p)) = √(40 x 0.10 x 0.90) ≈ 1.93.
To find the mean and standard deviation of the normal approximation, we use the same mean and standard deviation values
μ = np = 4
σ = √(np(1-p)) ≈ 1.93

To create a table for the line y=1-4x from x=-2 to x=2, we substitute in each x value into the equation, solve for y, and display these pairs in a table. The pairs are (-2, 9), (-1, 5), (0, 1), (1, -3), and (2, -7).
Explanation:
The equation of the line is y = 1 - 4x. To create a table showing the values of x and y where x is from -2 to 2, we need to substitute each value of x into the equation, solve for y, and then organize the results in a table.
When x = -2, y = 1 - 4*(-2) = 1 + 8 = 9When x = -1, y = 1 - 4*(-1) = 1 + 4 = 5When x = 0, y = 1 - 4*0 = 1When x = 1, y = 1 - 4*1 = 1 - 4 = -3When x = 2, y = 1 - 4*2 = 1 - 8 = -7

Last year Liz bought a book for $10. This year the same book is on sale for $5. What was the percent of change?
The percent of change in the price of the book is 50%.
To calculate the percent of change, we first need to find the difference between the original price and the new price. In this case, the original price of the book was $10, and the new price is $5. To find the difference, we can subtract the new price from the original price, which is:
$10 - $5 = $5
Now, we need to express this difference as a percentage of the original price. To do this, we divide the difference by the original price and then multiply by 100. In other words, we need to find the percentage that the original price has changed by. This can be represented mathematically as:
Percent of change = (Difference / Original price) x 100
Plugging in the values we found earlier, we get:
Percent of change = ($5 / $10) x 100
Percent of change = 0.5 x 100
Percent of change = 50%
This means that the price of the book has decreased by 50% from the original price of $10 to the sale price of $5.

If the area of a triangle is 72 square inches and the height is 6 inches, what is the length of the base
Answer: 24 inches.
Step-by-step explanation:
We can use the formula for the area of a triangle to solve for the length of the base:
A = (1/2)bh
where:
A = the area of the triangle (in this case, 72 square inches)
b = the length of the base (what we're trying to find)
h = the height of the triangle (in this case, 6 inches)
Plugging in the values we know, we get:
72 = (1/2)b(6)
72 = 3b
b = 24
Therefore, the length of the base of the triangle is 24 inches.

A polynomial p(x) has a relative maximum at (-2, 4), a relative minimum at (1,1), and a relative maximum at (5,7) and no other critical points. How many real zeros does p(x) have?a) oneb) twoc) threed) foure) five
The polynomial p(x) has option (c) three real zeros because it has a relative maximum at (-2, 4), a relative minimum at (1,1), a relative maximum at (5,7), and a negative leading coefficient.
Since p(x) has a relative maximum at (-2, 4), a relative minimum at (1,1), and a relative maximum at (5,7), it means that the degree of the polynomial must be odd and at least three.
Moreover, we know that p(x) has no other critical points. This means that p(x) does not change sign between these relative extrema, which in turn implies that there are no real zeros between these extrema.
Therefore, the number of real zeros of p(x) is either one or three. To determine the answer, we need to consider the leading coefficient of p(x).
If the leading coefficient is positive, then p(x) must eventually increase on both ends, since the degree is odd. This means that there is exactly one real zero.
If the leading coefficient is negative, then p(x) must eventually decrease on both ends. In this case, since there are three relative extrema, there must be three real zeros.
Thus, we need to find the sign of the leading coefficient of p(x). This can be done by looking at the relative extrema.
Since p(x) has a relative maximum at (-2, 4), we know that the leading coefficient is negative.
Therefore, the correct option is (c) three.
