Maya is estimating the product of 88 and 12. Which statements are true? Check all that apply.
Since Maya is estimating the product of 88 and 12, the statements that are true include the following:
If she rounds both values to the nearest ten, her estimate will be 900.If she rounds 88 to the nearest hundred and 12 to the nearest ten, her estimate will be 1,000.How to determine the true statements?In order to determine the statements that are true, we would have to evaluate each of the statement as follows:
"If she rounds both values to the nearest ten, her estimate will be 800."
Rounding up 88 and 12 to the nearest ten, we have the following:
Rounded up number = 88 ≈ 90
Rounded up number = 12 ≈ 10
Therefore, the product of 90 and 10 is given by:
Product = 90 × 10
Product = 900.
"If she rounds 88 to the nearest hundred and 12 to the nearest ten, her estimate will be 1,000."
Rounding up 88 to the nearest hundred, we have the following:
Rounded up number = 88 ≈ 100
Rounding up 12 to the nearest ten, we have the following:
Rounded up number = 12 ≈ 10
Therefore, the product of 100 and 10 is given by:
Product = 100 × 10
Product = 1,000.
In this context, we can reasonably and logically deduce only two statements are true while all of the other statements are false and incorrect.

A composition of rigid
motions maps one figure to another figure is each intermediate image in the composition congruent to the original and final figures? Explain.
Answer:
Swaped
Step-by-step explanation:
Yes. Because the figure maintained its congruency throughout every rigid motion. According to Theorem 3-3, a rigid motion is the combination of two or more rigid motions.
What types of motions create congruent figures?The two are said to be congruent if and only if one of two plane figures can be produced from the other by a series of rigid motions such as rotations, translations, and/or reflections.Because rigid motions preserve length and angle measurements, the corresponding parts of congruent figures are also congruent. As a result, if the corresponding parts of two figures are congruent, there is a rigid motion or a composite rigid motion that maps one figure onto the other.Every point in the plane can be moved in that direction using any method. a) The distance ratio between the two points remains constant. b) The relative positions of the points remain unchanged.Hence, Yes. Because the figure maintained its congruency throughout every rigid motion. According to Theorem 3-3, a rigid motion is the combination of two or more rigid motions. As a result, the original and final figures can be seen in agreement with each intermediate image.

first time to reach a height of 60 feet:
seconds
second time to reach a height of 60 feet:
seconds
The height reached by the projectile, described by the kinetic equation of motion of the projectile, indicates;
First time to reach a height of 60 feet; 0.4 seconds
Second time to reach a height of 60 feet; 2.1 seconds
What is a projectile?A projectile is an object that is launched using an applied force and after which is acted upon by gravitational and air wind motion forces.
The function for the height of the projectile is; h(t) = -16·t² + 40·t + 47
When the height of the projectile is 60 feet, we ge;
h(t) = 60 = -16·t² + 40·t + 47
Therefore; -16·t² + 40·t + 47 - 60 = 0
From which we get;
16·t² - 40·t + 13 = 0
t = (40 ± √(40² - 4 × 16 × 13))/(2 × 16)
t = (40 + 16·√3)/32 ≈ 2.1 seconds and t = (40 - 16·√3)/32 ≈ 0.4

A branch of a certain bank has six ATMs. Let X represent the number of machines in use at a particular time of day. The cdf of X is as follows:
F(x) =
0 x < 0
0.06 0 ≤ x < 1
0.16 1 ≤ x < 2
0.33 2 ≤ x < 3
0.69 3 ≤ x < 4
0.92 4 ≤ x < 5
0.99 5 ≤ x < 6
1 6 ≤ x
Calculate the following probabilities directly from the cdf
(a) p(2), that is, P(X = 2) (b) P(X > 3) (c)P(2 ≤ X ≤ 5) (d)P(2 < X < 5)
The probability directly from the cumulative distributive function:
P(X = 2) = 0.17 , P(X > 3) = 0.31 , P(2 ≤ X ≤ 5) = 0.76, P(2 < X < 5) = 0.42 ,
These calculations are essential in many areas of probability theory and statistics, including hypothesis testing, confidence intervals, and estimation.
(a) To find P(X = 2), we subtract the probability of the previous value from the probability of X being less than or equal to 2:
P(X = 2) = F(2) - F(1) = 0.33 - 0.16 = 0.17.
(b) To find P(X > 3), we subtract the probability of X being less than or equal to 3 from 1:
P(X > 3) = 1 - F(3) = 1 - 0.69 = 0.31.
(c) To find P(2 ≤ X ≤ 5), we subtract the probability of X being less than 2 from the probability of X being less than or equal to 5:
P(2 ≤ X ≤ 5) = F(5) - F(1) = 0.92 - 0.16 = 0.76.
(d) To find P(2 < X < 5), we subtract the probability of X being less than or equal to 2 from the probability of X being less than or equal to 5, and then subtract the probability of X being equal to 2:
P(2 < X < 5) = F(5) - F(2) - P(X = 2) = 0.92 - 0.33 - 0.17 = 0.42.
In summary, to calculate probabilities from a given cdf, we use the formula P(X = x) = F(x) - F(x-1) for discrete random variables, and P(a < X ≤ b) = F(b) - F(a) for continuous random variables. We can also use complement probabilities to find the probability of events such as P(X > a) or P(a < X < b). These calculations are essential in many areas of probability theory and statistics, including hypothesis testing, confidence intervals, and estimation.

what is the mean absolute division of 16 10 22 18 4 18 14 24 16 22
the mean absolute deviation of the set {16, 10, 22, 18, 4, 18, 14, 24, 16, 22} is 4.68.
To find the mean absolute deviation of a set of numbers, we first need to calculate the mean of the set.
The mean of the set {16, 10, 22, 18, 4, 18, 14, 24, 16, 22} is:
Mean = (16 + 10 + 22 + 18 + 4 + 18 + 14 + 24 + 16 + 22) / 10 = 16.4
Next, we need to calculate the absolute deviation of each number from the mean. The absolute deviation is the absolute value of the difference between the number and the mean.
The absolute deviations for each number in the set are:
|16 - 16.4| = 0.4
|10 - 16.4| = 6.4
|22 - 16.4| = 5.6
|18 - 16.4| = 1.6
|4 - 16.4| = 12.4
|18 - 16.4| = 1.6
|14 - 16.4| = 2.4
|24 - 16.4| = 7.6
|16 - 16.4| = 0.4
|22 - 16.4| = 5.6
Now, we need to find the mean of the absolute deviations.
Mean absolute deviation = (0.4 + 6.4 + 5.6 + 1.6 + 12.4 + 1.6 + 2.4 + 7.6 + 0.4 + 5.6) / 10
Mean absolute deviation = 4.68
Therefore, the mean absolute deviation of the set {16, 10, 22, 18, 4, 18, 14, 24, 16, 22} is 4.68.

identify which one of the following best describes the distribution of the following random variable. in 10 spins of the normal(0, 1) spinner, the number of spins that land on a negative value. chegg
The distribution of the following random variable the number of spins that land on a negative value in 10 spins follows a binomial distribution with parameters n = 10 (number of trials) and p (probability of success for each trial).
The random variable you described, which represents the number of spins in 10 trials that land on a negative value on a normal(0, 1) spinner, follows a binomial distribution.
The binomial distribution is characterized by having a fixed number of independent trials, each with two possible outcomes (success or failure), and a constant probability of success (p) for each trial. In this case, a "success" can be defined as a spin landing on a negative value.
In your scenario, each spin has two possible outcomes: landing on a negative value (success) or landing on a non-negative value (failure). The probability of success (p) is determined by the properties of the normal(0, 1) distribution.
Therefore, the number of spins that land on a negative value in 10 spins follows a binomial distribution with parameters n = 10 (number of trials) and p (probability of success for each trial).

solve the 3 × 3 system shown below. enter the values of x, y, and z. x 2y – z = –3 (1) 2x – y z = 5 (2) x – y z = 4
The solution to the given system of equations is x = 2, y = -1, and z = 1.
What are the values of x, y, and z that solve the given system of equations?To solve the system of equations, we can use methods such as substitution or elimination. Here, we will use the method of elimination to find the values of x, y, and z.
First, let's eliminate the variable x by multiplying equation (1) by 2 and equation (3) by -1. This gives us:
2x + 4y - 2z = -6 (4)
-x + y - z = -4 (5)
Next, we can subtract equation (5) from equation (4) to eliminate the variable x:
5y - z = 2 (6)
Now, we have a system of two equations with two variables. Let's eliminate the variable z by multiplying equation (2) by 2 and equation (6) by 1. This gives us:
4x - 2y + 2z = 10 (7)
5y - z = 2 (8)
Adding equation (7) and equation (8), we can eliminate the variable z:
4x + 5y = 12 (9)
From equation (6), we can express z in terms of y:
z = 5y - 2 (10)
Now, we have a system of two equations with two variables again. Let's substitute equation (10) into equation (1):
x + 2y - (5y - 2) = -3
x - 3y + 2 = -3
x - 3y = -5 (11)
From equations (9) and (11), we can solve for x and y:
4x + 5y = 12 (9)
x - 3y = -5 (11)
By solving this system of equations, we find x = 2 and y = -1. Substituting these values into equation (10), we can solve for z:
z = 5(-1) - 2
z = -5 - 2
z = -7
Therefore, the solution to the given system of equations is x = 2, y = -1, and z = -7.

(enter your answers as a comma-separated list.)
The northeast area consists of nine states, hence this variance can have any value between 0 and 9, inclusive.
The proportion of northeastern states having an unemployment rate lower than 8.3% is the random factor of interest. The random variable will have a value of 0 if the unemployment rate was higher compare to 8.3% in each of the nine states. The binomial distribution would have a value of 1 if only one state had an unemployment rate lower than 8.3%.
The random variable will assume on a value in the range if two states have a rate of unemployment lower than 8.3%, and so on, up to a limit result of 9 that all nine states include an poverty rate lower than 8.3%.The government can monitor the northeast region's economic conditions and make accurate policy decisions by keeping tabs on poverty in these nine states.

Using line tangent, the approximation for f(2.1) is 3.95
Given,
The point (a, f(a)) is on the line tangent to the graph of y = f(x) at x = a, which has a slope of f'(a).
The equation be like;
y - f(a) / (x - a) = f'(a)
y = f'(a) (x - a) + f(a)
Using the provided data and a = 2, we can determine that the tangent line to the graph of y = f(x) at x = 2 has equation
y = f'(2) (x - 2) + f(2)
y = -1/2 (x - 2) + 4
To compute a "approximation of f(2.1) using the line tangent to the graph of f at x = 2," one must substitute x = 2.1 for f in the equation for the tangent line (2.1). You get 2.1 when you plug this in.

what does the highest point on a bell-shaped curve represent?
The highest point on a bell-shaped curve represents the peak or maximum value of the distribution. This point is known as the mode of the distribution.
In a bell-shaped curve, also known as a normal distribution or Gaussian distribution, the data is symmetrically distributed around the mean. The curve is characterized by a central peak, and the highest point on this peak corresponds to the mode.
The mode represents the most frequently occurring value or the value that has the highest frequency in the dataset. It is the point of highest density in the distribution.
The bell-shaped curve is often used to model naturally occurring phenomena and is widely applied in statistics and probability theory. The mode provides information about the most common or typical value in the dataset and is useful for understanding the central tendency of the distribution.
While the mean and median also have significance in a normal distribution, the highest point on the bell-shaped curve specifically represents the mode, indicating the value with the highest occurrence in the dataset.

the taylor series for a function f about x=1 is given by
The Taylor series for a function f about x=1 is an infinite sum that represents the function using its derivatives at x=1. It starts with the value of the function at x=1 and includes terms involving higher derivatives multiplied by powers of (x-1) divided by factorials. It allows us to approximate the function near x=1 using a polynomial.
1. The first term, f(1), represents the value of the function at x=1.
2. The subsequent terms involve the derivatives of the function at x=1. The second term, f'(1)(x-1), is the first derivative of f at x=1 multiplied by (x-1).
3. Each subsequent term involves higher derivatives of f at x=1, with each derivative being multiplied by (x-1) raised to a power and divided by the corresponding factorial.
The Taylor series is a way to represent a function as an infinite sum of terms derived from its derivatives at a specific point. In this case, the Taylor series for function f about x=1 is given by f(x) = f(1) + f'(1)(x-1) + f''(1)(x-1)^2/2! + f'''(1)(x-1)^3/3! + ...
Each term involves a derivative of f evaluated at x=1, multiplied by (x-1) raised to a power and divided by the corresponding factorial. By including more terms in the series, we can approximate the function better near x=1 using a polynomial.
