We need to use  order of precedence of operators to evaluate it.

BoDMAS acronym to remember order of precedence of operators

Bracket of Division Multiplication Addition Subtraction

Since multiplication has greater precedence, we evaluate it first

33+ 1 · 9 +12 = 33+9+12

now, all the operators are in same level of precedence. so, adding them together we have

33+9+12 = 54

∴ 33+ 1 · 9 +12 = 54

What are my zeros (x^2 - 8x + 1)?
Pavel [41]

Answer:

x= 7.87298334621                          x=.12701665379

Step-by-step explanation:

This is in standard form so we have to factor this into

x^2-8x + 16 + 1 = 16

(x-4)^2 = 15

(x-4) = \sqrt{15\\}

x-4= ± 3.87298334621

x-4 = 3.87298334621                      x-4= -3.87298334621

x= 7.87298334621                          x=.12701665379

PLEASE HELP DONT JUST GUESS JUST TO GET POINTS LOL Plot any four points on the coordinate plane and connect them to form a quadr
sveticcg [70]

The quadrilateral formed by this process will always be a parallelogram

<h3>Quadrilaterals</h3>

A quadrilateral is simply any polygon that has four sides and four corners.

Common examples are:

  • Square
  • Rectangle
  • Rhombus
  • Kite
  • Trapezoid
  • Rhombus
  • Parallelogram

<h3>Figure 1</h3>

A square is drawn at the coordinates:

(0,0), (6,0), (0,6) and (6,6)

The midpoints of the square sides are at the following coordinates:

(0,3), (3,6), (6,3) and (3,0)

When the points of the midpoints are joined together, they form a parallelogram

<h3>Figure 2</h3>

A trapezoid is drawn at the coordinates:

(0,0), (2,6), (8,6) and (10,0)

The midpoints of the square sides are at the following coordinates:

(5,0), (5,6), (1,3) and (9,3)

When the points of the midpoints are joined together, they form a parallelogram

Hence, the quadrilateral formed by this process will always be a parallelogram

(08.03)jasper is using the following data samples to make a claim about the house values in his neighborhood: house value a $150
ipn [44]

Part A) Jasper should use the median because there is an outlier that affects the mean is the correct answer.

Part B) Option (D) no, because there is a lot of variability in the art book data is the correct answer.

In this question,

Part A)

The median is the middle number in a sorted, ascending or descending list of numbers and can be more descriptive of that data set than the average. The numbers are ordered in ascending order. Once the numbers are ordered, the middle number is called the median of the given data set.

The median is important because it gives us an idea of where the center value is located in a dataset. The median is the most informative measure of central tendency for skewed distributions or distributions with outliers.

The house values in Jasper's neighborhood,

a) $150,000, b) $175,000, c) $200,000 ,d) $167,000, e) $2,500,000

The value of house E is very high from other houses in Jasper's neighborhood. The value of house E will make the mean house value above the center of the data as House E is an outlier for our given data.

Thus the median of a data set with an outlier is not affected by the value of outlier. Therefore, Jasper should use the median because there is an outlier that affects the mean is the correct answer.

Part B)

The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset. The mean absolute deviation is specially important in data analysis where the average value can be deceptive.

A small mean absolute deviation tells us that most of the data values are very close to the mean. A high mean absolute deviation tells us that many of the data values are spread out further from the mean.

Magdeline selects 25 pages from each book, then Calculates Mean, Median, Mean Absolute Deviation of number of words on each page.

Book                Mean      Median     Mean Absolute Deviation

Art                      68.7          50                   15.4

Science             54.2          55                    7.9

Magdeline claims that the mean number of words on each page in the art book is greater than the mean number of words on each page in the science book, the art book has more words per page is not a valid inference.

Because variability from mean in art book is more than variability from mean in science book and the mean absolute deviation measures variability from mean. Thus option (D) no, because there is a lot of variability in the art book data is the correct answer.
