the data set.

lower quartile: $

upper quartile: S

?

$1.39 $1.40 $1.44 $1.50 $1.60 $1.63 $1.65 $1.80

Answer:

**Answer:**

Lower quartile: $1.42

Upper quartile: $1.64

**Step-by-step explanation:**

The **median **is the **middle value** when all data values are placed in order of size.

The ordered **data set** is:

$1.39 $1.40 $1.44 $1.50 $1.60 $1.63 $1.65 $1.80

There are** 8 data values** in the data set, so this is an** even data set**.

Therefore, the **median **is the **mean **of the **middle two values**:

Place "||" in the middle of the data set to signify where the median is:

$1.39 $1.40 $1.44 $1.50 ║ $1.60 $1.63 $1.65 $1.80

The** lower quartile **(Q₁) is the **median **of the **data points **to the **left **of the median. As there is an even number of data points to the left of the median, the lower quartile is the mean of the the middle two values:

The** upper quartile **(Q₃) is the **median **of the **data points **to the **right **of the median. As there is an even number of data points to the right of the median, the upper quartile is the mean of the the middle two values:

Answer:

**Answer:**

to find the lower quartile and upper quartile of the given dataset, we need to first arrange the data in ascending order:

$1.39, 1.40, 1.44, 1.50, 1.60, 1.63, 1.65, 1.80$

The median of the dataset is given as $1.55$. Since there are an even number of data points, the median is the average of the two middle values, which in this case are $1.50$ and $1.60$.

Now, we need to find the lower quartile and upper quartile. The lower quartile is the median of the lower half of the data set, and the upper quartile is the median of the upper half of the data set.

The lower half of the dataset is $1.39, 1.40, 1.44, 1.50$. The median of this half is the average of the middle two values, which are $1.40$ and $1.44$.

Therefore, the lower quartile is $1.42$.

The upper half of the dataset is $1.60, 1.63, 1.65, 1.80$. The median of this half is the average of the middle two values, which are $1.63$ and $1.65$.

Therefore, the upper quartile is $1.64$.

Hence, the lower quartile of the dataset is $1.42$ and the upper quartile is $1.64$.

**Answer:**

205.599

**Step-by-step explanation:**

**Answer:**

205.599 yards

**Step-by-step explanation:**

1 meter = 1.09361 yards

**Multiply 188 meters by **1.09361 yards

188 meters = (1.09361 yards) x (188 meters)

= 205.599 yards

b)postulate

c)definition

d)conjecture

The statement given in the **statement **is the **definition **of **square**.

A **square **is closed, **two-dimensional** shape with 4 **equal sides** and all the internal angles are **right angles.**

- In the question it is given that A
**square**is a figure with four sides of**equal length**and**four right angles**.

So this is nothing but the **definition **of **square **.

So the correct answer is **definition**

28+3(5d-3)

**Answer:**

15d+19

**Step-by-step explanation:**

distribute 3(5d-3) first

= 15d-9

the expression is now 28+15d-9

combine 28 and -9

=19

bam u now have 15d+19

Answer:

11481.4875 km

Step-by-step explanation:

Given the that :

Galapagos island and Island of Naura are on the equator

Galapagos = 90.30°W

Island of Naura = 166.56°E

Ensuring same bearing is used for both :

Island of Naura = 166.56°E = (360° - 166.56°) = 193.44°W

Hence, we can calculate the difference in the bearing of both locations :

(193.44 - 90.30)°W = 103.14°

Hence the distance between Galapagos and Island of Naura along the equator is :

(Difference in bearing / total bearing) * earth's Circumference

Earth's Circumference = 40,075km

(103.14 / 360) × 40,075

0.2865 × 40,075

= 11481.4875 km

=
