First you make 3/10=0.3 the 1/3=0.33 then 0.3+0.33=0.63

Gabrielle is the correct one.

The largest positive integer m that divides both x and y is the GCF of two or more non-zero integers, x, and y. The GCF stands for the greatest common factor. Here, greatest might be changed to highest, and factor to divisor. Therefore, the greatest common factor is often referred to as the highest common divisor )(HCD), highest common factor (HCF), or greatest common divisor (GCD.

Fractions, which are frequently employed in daily life, are almost always utilized with GCF. Finding the GCF of the denominator and numerator will allow you to obtain the necessary reduced form for simplifying a fraction or ratio. The greatest number that can divide two numbers x and y is their GCF.

One reason for using a t distribution instead of the standard normal curve to find critical values when calculating a level c confidence interval for a population mean is that (b) z requires that you know the population standard deviation s.

The t distribution is used when the population standard deviation is unknown and is estimated from the sample. The t distribution has fatter tails than the standard normal curve, which makes it more appropriate for smaller sample sizes. When the sample size is large, the t distribution approaches the standard normal curve, and the z distribution can be used instead.

Multiply the original price and the percentage that represents the sale price; the result is the sale price of the blazer in dollars: $90 × 0.7 = $63. So if the blazer is on sale for 30 percent off, you'll pay the remaining 70 percent of the price, which is $63.

Mean is used to measure the center of a set of values. It is good for summarizing values which are generally pretty similar to each other.

Mean is more usually referred to as the average. It is calculated by adding up all of the values and dividing by the total number of values. It is a good way for summarizing the center of values which are commonly very similar to each other.

The mean is the most often used measure of central tendency since it uses all values in the data set to give us an average. For data from skewed distributions, the median is better than the mean because it is not influenced by large values.

The Lagrange multipliers fail to solve the problem because  g = 0 at the coordinates (x, y) = (0, 1) where f reaches its minimum on g = 0,

The Italian mathematician Joseph-Louis Lagrange is honoured by having his multiplier method named after him. In order to apply the derivative test of an unconstrained problem to a constrained problem, it is necessary to convert it into a different form.

Moreover, this technique is frequently employed in mathematical optimization. When a function of the form f(x, y, and z) is subject to equality constraints of the form g(x, y, and z) = k or g(x, y, and z) = 0, one useful technique is the method of Lagrange's multipliers. This means that it depends on the values of the desired variable exactly satisfying the terms of one or more equations.

A subset of a population used by statisticians to make predictions about a population is called a sample.

a sample is a smaller, representative group selected from the larger population. The sample is used to gather data and make inferences about the entire population. By analyzing the sample, statisticians can make predictions about the characteristics, trends, or behaviors of the population without having to study every individual within it. This method saves time, resources, and effort while still providing accurate results.

A sample is a crucial tool in statistical analysis, allowing statisticians to make informed predictions about a population based on the study of a smaller, representative subset.

Step-by-step explanation:

The given system is a consistent system

To determine whether the system is consistent, we can use row operations to put the system in row echelon form.

Row echelon form is a technique in linear algebra used to simplify a matrix into a particular form, making it easier to analyze and solve linear systems of equations.

By transforming a matrix into row echelon form, it becomes clear whether the system is consistent (has at least one solution) or inconsistent (has no solutions).

Specifically, a system is consistent if the row echelon form has no rows of the form [0 0 ... 0 | b], where b is a nonzero constant, indicating that there is no contradiction in the system. If such a row is present, the system is inconsistent.

After performing the row operations, we obtain:

1       -3      1      |      0

0       \(\frac{7}{2}\)    \(-\frac{1}{2}\)      |     0

0      0      \(\frac{2}{3}\)       |      0

From the row echelon form, we can see that there are no rows of the form [0 0 0 | k], where k is a nonzero constant.

This means that the system has a unique solution, and is consistent.

the angle between 0 and 2π that is coterminal with 17π/4 is π/4.

To find the angle between 0 and 2π that is coterminal with 17π/4, we need to find an equivalent angle within that range.

Coterminal angles are angles that have the same initial and terminal sides but differ by a multiple of 2π.

To determine the coterminal angle with 17π/4, we can subtract or add multiples of 2π until we obtain an angle within the range of 0 to 2π.

Starting with 17π/4, we can subtract 4π to bring it within the range:

17π/4 - 4π = π/4

The angle π/4 is between 0 and 2π and is coterminal with 17π/4.

Answer:

3.7

Step-by-step explanation:

To find the error interval for X, we need to consider the possible range of values that X could take, given that it was rounded to 1 decimal place as 3.7.

Since 3.7 was rounded up from some number greater than or equal to 3.65 and less than 3.75, we can express the error interval as follows:

3.65 ≤ X < 3.75

This means that any number between 3.65 and 3.75, when rounded to 1 decimal place, would result in 3.7 as the rounded value.

Answer:

3.65 ≤ x ≤ 3.75

Step-by-step explanation:

1. Identify the place value of the degree of accuracy stated – this will be the interval size required for the error interval.

To the nearest decimal place -> 0.1

2. If rounded: Divide this place value by 2, and then add and subtract this amount to the given value to give the maximum and minimum values for your error interval.

0.1/2 = 0.05

Max: 3.7 + 0.05 = 3.75

Min: 3.7 - 0.05 = 3.65

3. Write your error interval as an inequality in the form

Min  ≤ x <   Max

3.65 ≤ x ≤ 3.75
