Substituting a cumulative area of 0.2420, a mean of 0, and a standard deviation of 1 into the inverse normal distribution, the z-score is -0.71 to two decimal places.

Given that the cumulative area of 0.2420, a mean of 0, and a standard deviation of 1, the required z-score has to be determined.We know that the standard normal distribution with mean 0 and standard deviation 1 is denoted as N(0, 1). The inverse normal distribution with a cumulative area of x is the inverse of the normal distribution with cumulative area x. Let z be the z-score corresponding to a cumulative area of x, then we can say that P(Z ≤ z) = x, where P is the cumulative distribution function of the standard normal distribution.

Substituting the given values in the formula, we get:0.2420 = P(Z ≤ z)We need to find the corresponding z-value using inverse normal distribution. Therefore, we take the inverse of the cumulative distribution function, as follows:z = invNorm(0.2420)z = -0.71 (rounded to two decimal places)Thus, the required z-score is -0.71.

The product of the volume and total surface area of the given right conical frustum is approximately 146520π². To find the product of the volume and total surface area of a right conical frustum, we first need to determine the individual values of volume and surface area.

The volume of a frustum can be calculated using the formula:

V = (1/3)πh(r₁² + r₂² + r₁r₂),

where h is the height of the frustum, r₁ and r₂ are the radii of the larger and smaller bases, respectively.

In this case, we are given that the radii of the larger and smaller bases are 12 and 9 units, respectively. We also know that the two bases are 4 units apart, which means the height of the frustum is 4 units.

Substituting the given values into the formula, we have:

V = (1/3)π(4)(12² + 9² + 12*9)

 = (1/3)π(4)(144 + 81 + 108)

 = (1/3)π(4)(333)

 = (4/3)π(333)

 ≈ 444π cubic units

Now, let's move on to calculating the total surface area of the frustum. The formula for the total surface area is:

A = π(r₁ + r₂)ℓ + πr₁² + πr₂²,

where ℓ is the slant height of the frustum.

Since the frustum is a right frustum, the slant height ℓ can be found using the Pythagorean theorem:

ℓ = √(h² + (r₁ - r₂)²)

Substituting the given values, we have:

ℓ = √(4² + (12 - 9)²)

 = √(16 + 9)

 = √25

 = 5

Now we can calculate the total surface area:

A = π(12 + 9)(5) + π(12²) + π(9²)

 = π(21)(5) + π(144) + π(81)

 = 105π + 144π + 81π

 = 330π square units

Finally, to find the product of the volume and total surface area, we multiply the two values:

VA = (444π)(330π)

  ≈ 146520π²

Therefore, the product of the volume and total surface area of the given right conical frustum is approximately 146520π².

Answer:

Therefore, we have proven that the product of two numbers is equal to the product of their least common multiple and their greatest common divisor.

Step-by-step explanation:

let's say we have two numbers, a and b. We can write the following:

a = m * d

b = n * d

The LCM of a and b is given by:

LCM(a, b) = m * n * d

a * b = (m * d) * (n * d)

a * b = m * n * d * d

a * b = m * n * (d * d)

a * b = m * n * LCM(a, b)

Therefore, we have proven that the product of two numbers is equal to the product of their least common multiple and their greatest common divisor.

Answer:

The products of -3(1) and -3(-1) are the same because both expressions result in the multiplication of -3 and a number, where one of the numbers is positive and the other is negative. The product of these two numbers is always negative.

Step-by-step explanation:

-3(1) means multiplying -3 by 1, which gives -3 as the product.

-3(-1) means multiplying -3 by -1, which gives 3 as the product.

Even though the two expressions are different, we can see that both involve multiplying -3 with a number, where one of the numbers is positive and the other is negative.

When we multiply a negative number and a positive number, the product is always negative. Similarly, when we multiply a negative number and a negative number, the product is always positive.

So, in both -3(1) and -3(-1), we are multiplying a negative number (-3) with a positive number (1 in the first expression and -1 in the second expression). Therefore, the products of both expressions are negative (-3 in the first expression and 3 with a negative sign in the second expression).

Hence, we can conclude that the products of -3(1) and -3(-1) are the same and equal to -3.

1 False

2 True

3 False

4 False

You are correct that statement 1 is false. The covariance of two random variables being zero does not necessarily imply that the random variables are independent. Independence requires that the joint probability distribution of the two variables factorizes into the product of their marginal probability distributions.

Statement 2 is true. The continuity correction is used when approximating probabilities pertaining to a continuous random variable with a discrete distribution, such as using a normal approximation to estimate probabilities of a binomial distribution. It helps to account for the discrepancy between continuous and discrete distributions.

Statement 3 is false. Mutually exclusive events, by definition, cannot occur simultaneously. However, this does not imply independence. Independence requires that the occurrence of one event does not affect the probability of the other event, regardless of whether they are mutually exclusive or not.

Statement 4 is also false. Even if X and Y are independent random variables and their moments exist, the expectation of the product of X and Y, E[XY], may not be equal to the product of their individual expectations, E[X]E[Y]. This equality holds only if X and Y are uncorrelated, not just independent.

The number of megafilns-per-strord should be smaller than the number of filns-per-strord since a mega is a conversion factor of 10³ and is greater than 1, hence 1 megafiln is greater than 1 filn.

(2)2 grees = 10 twibbs...

(3)5 grees = 1 bic...

(4)Note that the grees are in both the numerator and denominator of the second unit conversion factor (3). Hence we can cancel out the grees by using it twice in the numerator and denominator. Now using the given conversion factors in equation (1), we get:

7 glint/twibb=7 glint/ (10 grees/2 grees)=14 glint/10 grees=14 glint/ (5 grees/12 grees)=16.8 filn/strord

(b) We need to convert the result of part (a) from filn/strord to megafiln/strord.

1 mega = 106

Thus 1 megafiln = 106 filn

16.8 filn/strord = (16.8 filn/strord) x (1 megafiln/106 filn) = 1.68 x 10-5 megafiln/strord

The number of megafilns-per-strord should be smaller than the number of filns-per-strord since a mega is a factor of 10³ and is greater than 1, hence 1 megafiln is greater than 1 filn.

The length of X=10 in a right angle triangle .

what is right angle triangle ?

A right-angled triangle, also known as a right triangle, is a triangle in which one of the angles is a right angle, which is exactly 90 degrees. The side opposite to the right angle is called the hypotenuse, while the other two sides are called legs or catheti. The Pythagorean Theorem is a fundamental theorem that applies to right triangles and states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. Right triangles have many applications in mathematics and other fields, such as engineering and physics.

According to the question:
Since the line drawn from B is perpendicular to AC, we have two similar triangles: BAE and BCE.

Using the Pythagorean Theorem on triangle BAE, we get:

AB² + AE² = BE²

AB² + 12² = BE²

AB² = BE² - 12²

Using the Pythagorean Theorem on triangle BCE, we get:

BC² + CE² = BE²

10² + CE² = BE²

CE² = BE² - 10²

Since AB = AC - BC and AB² = AC² - 2AC * BC + BC², we can substitute and simplify:

(AC - 10)² + 12² = BE²

AC² - 20AC + 100 + 144 = BE²

AC² - 20AC + 244 = BE²

Substituting the previous expressions for AB² and CE² into the equation CE² = BE² - 10², we get:

AC² - 20AC + 244 = AB² - 100

AC² - AB² - 20AC + 344 = 0

(AC - AB - 4)(AC + AB - 16) = 0

Since AC > AB, we have AC + AB - 16 = 0, which implies AC = 16 - AB. Substituting into the equation 10² + CE² = BE², we get:

100 + CE² = AB² - 144

CE² = AB² - 244

CE² = (16 - AC)² - 244

CE² = (16 - (16 - AB))² - 244

CE² = AB² - 244

Substituting the expression for AB² from above, we get:

CE² = BE² - 12² - 244

CE² = 10² + CE² - 12² - 244

CE² - CE² = -100

CE = sqrt(100) = 10

Therefore, EC = 10. so the length of X=10

Linear equations are a subset of non-linear equations, and the equation 3xy = 9 is a non-linear equation.

The equation 3xy = 9 is not a linear equation. It is a non-linear equation. Linear equations are first-degree equations, meaning that the exponent of all variables is 1. A linear equation is represented in the form y = mx + b, where m and b are constants.

The variables in linear equations are not raised to powers higher than 1, making it easier to graph them. In contrast, non-linear equations are any equations that cannot be written in the form y = mx + b. Non-linear equations have at least one variable with an exponent that is greater than or equal to 2. Non-linear equations are harder to graph than linear equations.

The answer is false, the equation 3xy = 9 is a non-linear equation, not a linear equation. Non-linear equations are any equations that cannot be written in the form y = mx + b. They have at least one variable with an exponent that is greater than or equal to 2.

The total value of her coins is 11615 cents.

Let's assume Patty initially had x nickels and y dimes. The total value of her coins can be represented as:

Value = 5x (since each nickel is worth 5 cents) + 10y (since each dime is worth 10 cents)

According to the given condition, if the nickels were dimes and the dimes were nickels, the new total value would be:

New Value = 5y + 10x

The difference in value is given as 7070 cents, so we can set up the equation:

New Value - Value = 7070

(5y + 10x) - (5x + 10y) = 7070

Simplifying the equation:

5y + 10x - 5x - 10y = 7070

5x - 5y = 7070

Dividing both sides of the equation by 5:

x - y = 1414

Now, since Patty initially had a total of 2020 coins, we can set up another equation:

x + y = 2020

Using the equations x - y = 1414 and x + y = 2020, we can solve for x and y by adding the two equations:

2x = 3434

x = 3434 / 2

x = 1717

Substituting the value of x into x + y = 2020:

1717 + y = 2020

y = 2020 - 1717

y = 303

Therefore, Patty initially had 1717 nickels and 303 dimes. The total value of her coins is:

Value = 5x + 10y = 5(1717) + 10(303) = 8585 + 3030 = 11615 cents.
