Applying the properties of a parallelogram, the values of x and y are:

y = 81°

The shape given is a parallelogram, therefore:

3x = 2x + 33 [opposite angles]

3x - 2x = 33

x = 33

3x + y = 180 [adjacent angles]

Plug in the value of x

3(33) + y = 180

When 122 is decreased by five times a number, the result is equal to the number increased by 20 so the number is 17 .

Given :

Number :

A number is an arithmetic value used for representing the quantity and used in making calculations.

Let x be the number .

( 122- 5x ) = ( x + 20 )

122 - 5x = x + 20

122 - 6x = 20

122 - 20 = 6x

102 = 6x

divide by 6 on both sides

6x / 6 = 102 / 6

x = 102 / 6

The nature of the roots of 2x² 3x 5 0 are imaginary, as it is not possible to solve for real numbers.

To solve this equation, we first factor out the coefficients (2 and 5). Factoring out 2 gives us x² + 1.5x + 5 = 0. After that, we solve for x using the quadratic formula:

x

= -1.5 ± √(-1.5² - 4(1)(5)) / 2(1). This is reduced to x = -1.5 9.5 / 2, an imaginary number that cannot be solved using real values. This indicates that the equation's roots are fictitious.

x

= -1.5 ± √(-1.5² - 4(1)(5)) / 2(1)

x = -1.5 ± √9.5 / 2

x = -1.5 ± √(9.5)i / 2

To determine whether there are differences between more than two population variances, utilise anova is True

What is Anova?

A statistical technique called analysis of variance, or ANOVA, divides observed variance data into various components for use in further testing. When there are three or more data groups, a one-way ANOVA is used to find out how the dependent and independent variables are related.

Concept:

One-way ANOVAs are typically used when there are three or more categorical independent groups, although they can also be employed when there are only two groups (but an independent-samples t-test is more commonly used for two groups)

A statistical procedure called Analysis of Variance (ANOVA) is used to examine variations between the means (or averages) of several groups. It is used in a variety of situations to discover whether there are any differences between the means of various groups.

To determine how the values of two categorical factors affect the mean of a quantitative variable, a two-way ANOVA is utilised. When you wish to determine how two independent factors interact with one another to effect a dependent variable, use a two-way ANOVA.

The absence of a difference in means is always the null hypothesis in an ANOVA. The alternative or research hypothesis, which is typically expressed in words rather than mathematical symbols, asserts that the means are not all equal. The research hypothesis involves any difference in means, such as when all four means are different from one another, one mean differs from the other three, two means differ, and so on. All scenarios other than the equality of all means described in the null hypothesis are covered by the alternative hypothesis, as it was previously illustrated.

Percent of the daily value for saturated fat provided would be 48%

What is Percent Daily Value?

Daily Values are recommendations that specify the amounts of certain nutrients that the average person should obtain each day. Daily Values are only a general guide because they are calculated for the average person who consumes a total of 2,000 calories a day.

If the total saturated fat for the meal is 95 grams, this is equal to 95,000 milligrams of saturated fat.

To find the percent daily value for saturated fat from this meal, we can use the following formula:

percent daily value = (total saturated fat / recommended daily intake) * 100

= (95,000 / 2000) * 100

= 47.5

Rounded to the nearest whole number, the percent daily value for saturated fat from this meal is approximately 48%

This means that this meal provides approximately 48% of the recommended daily intake of saturated fat.

Hence, Percent of the daily value for saturated fat provided would be 48%

Step-by-step explanation:

The slope of the line 4y - 3x = 1 is 3/4.

A line's slope is the ratio of how much y grows as x grows by a certain amount. You may determine a line's slope by looking at how steep it is or how much y grows as x grows. Anywhere along the line, the slope is uniform. In mathematics, measuring steepness is a common goal. It is obvious that slopes B and C are steeper than slope A. They both stand seven units tall, although slope A is only four. Therefore, it would seem that steepness and height are related.

Given

Equation

4y - 3x = 1

3x added to both sides,

4y = 1 + 3x

Dividing by 4,

y = 3/4x + 1/4

Step-by-step explanation:

The types of continuity of a function are: pointwise continuity, uniform continuity, absolute continuity, and uniform convergence.

The types of continuity of a function are: pointwise continuity, uniform continuity, absolute continuity, and uniform convergence. Pointwise continuity means that the function is continuous at each point in its domain. Uniform continuity means that the function is continuous over some larger region. Absolute continuity means that the function is continuous over its entire domain. Finally, uniform convergence means that the function converges to a limit value over a range of values. Pointwise continuity is the weakest form of continuity and uniform convergence is the strongest.

Population parameters are used to estimate sample statistics, and this is true.

Population parameters are used to describe the characteristics of a population, such as the mean, median, and standard deviation, and are used to make inferences about a population. Sample statistics, on the other hand, are used to describe the characteristics of a sample of a population. For example, a sample statistic could be the mean of a sample of people's heights.

To estimate sample statistics, population parameters must first be known. For example, the sample mean can be estimated using the population mean. If the population means are unknown, then the sample means can be estimated using the sample mean.

In conclusion, population parameters are used to estimate sample statistics, and this is true. Population parameters provide useful information about a population that can be used to make inferences about a sample. Knowing the population parameters allows researchers to make more accurate estimates of sample statistics, which in turn can be used to make more reliable inferences about a population.
