Determine whether each quadrilateral is a parallelogram. Justify your answer.
Lina20 [59]

Answer:

4. Parallelogram

5. Parallelogram

6. Parallelogram

Step-by-step explanation:

  • 4. This is a parallelogram because the longer sides are parallel to each other and the shorter sides are also parallel to each other. Hence, this is a parallelogram.
  • 5. This is a parallelogram because it's angles are the same to the opposite angles. Hence, this is a parallelogram.
  • 6. This is a parallelogram because the longer sides are parallel to each other and the shorter sides are also parallel to each other. Hence, this is a parallelogram.

6. Jessica bought a new suitcase. The sales tax was 4.5%. If the amount of
ra1l [238]

Answer:

$ 154

Step-by-step explanation

Let the value of suitcase=x

x × 4.5% = 6.93 (converted the question into equation)

x × \frac{4.5}{100} = 6.93 (converted the percentage into fraction)

x = 6.93 x \frac{100}{4.5} (took reciprocal of 4.5/100 after moving it to the other side of the equation)

x = \frac{693}{4.5} (multiplied the values)

x = 154 $ (simplified the fraction)

Use the box plot to answer the questions. What is the range of Charles’s scores? What is the median of Charles’s scores? What is
vekshin1

Box-plot describes 5 important data of the observations. We get following values for range, median and IQR as:

  • The range of Charles' scores is 20
  • The median of Charles' scores is 90
  • The IQR of Charles' scores is 8

<h3>How does a boxplot shows the  data points?</h3>

A box plot has 5 data description.

  • The leftmost whisker shows the minimum value in the data.
  • The rightmost whisker shows the maximum value in the data.
  • The leftmost line in the box shows the first quartile.
  • The middle line shows the median, also called second quartile.
  • The last line of the box shows the third quartile.

<h3>How to find the interquartile range?</h3>

IQR(inter quartile range)  is the dfference between third and first quartile. (Its the horizontal length of the box)

<h3>What is the range of a data set?</h3>

Range = Maximum value of the data set - Minimum value of the dataset

The missing box plot is attached below for the given problem.

From the given data, we see that, the left and right whiskers are on  80 and 100 respectively.

The left and right limit of the box are on 85 and 93 respectively.

The middle line lies on 90.

Thus, we get:

  • Minimum score = left whisker = 80
  • Maximum score = right whisker = 100
  • First quartile = left limit of box = 85
  • Third quartile = right limit of box = 93
  • Second quartile = median = middle line's position in the box = 90

Thus, we get:

  • Range of Charles' score = Max - min value = 100 = 80 = 20
  • Median of Charles' score =  90
  • IQR = third quartile - first quartile = 93 - 85 = 8

aniked [119]
The best and most correct answers among the choices provided by the question are:

<span>▢A. -2x+3y=-15
▢B. y=2/3x-5</span>

y = mx + b. where m is the slope<span> of the line and b is the y-</span>intercept<span> of the line, or the y-coordinate of the point at which the line crosses the y-axis. To write an equation in </span>slope-intercept form<span>, given a graph of that equation, pick two points on the line and use them to find the </span>slope<span>.</span>
