What is an expression?
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Step 1:
2.5 (42 ÷ 3.2 – 10(0.2) + 3) - 5.2
Step 2:
2.5 (42 ÷ 3.2 – 2 + 3) - 5.2
Step 3:
2.5 (13.125 + 1) - 5.2
Step 4:
2.5 (14.125) - 5.2
Step 5:
35.3125 - 5.2
Step 6:
30.1125
Thus,
The value of the expression is 30.1125.

what is the best measure of center for this data set (FQ, mean, median, or range) , and its value is (3, 4, 4.5, or 6.8)
Answers
Answer: The best measure of center for this data set is median , and its value is 4.5 .
Step-by-step explanation:
The given data set : {5, 3, 5, 30, 4, 5, 4, 3, 4, 5}
We can see that it has an outlier (i.e. 30) which is extremely large from all the values.
We know that to measure the center of tendency we measure one of three things arranged in ascending order:
Mode< Median <Mean
But mean gets affected by outlier value.
Then the best measure of center for this data set must be Median.
For this, arrange given data set in order:
{3 ,3 ,4 ,4 ,4 ,5 ,5 ,5 ,5 ,30 }
Since , the number of data values = 10 (even)
Then , Median = Mean of two middle most numbers
Hence, the best measure of center for this data set is median , and its value is 4.5 .

The sides given relative to angle x is the adjacent and opposite side. We can find x by using a trig function.
When using the adjacent and opposite sides, we use tangent.
The tan. of an angle, in this case x, is the opposite side over the adjacent side.
tan x=6/15
x=arc tan 6/15≈22

Answer:
Option A is correct
k = 2/5
Step-by-step explanation:
The rule of dilation with scale factor k is given by:
As per the statement:
Line AB has a length of 5 cm. The line segment is dilated to produce line A'B', which has a length of 2 cm.
⇒original Length (AB)= 5 cm
and
Image length (A'B') = 2 cm
Apply the rule of dilation we have;
Substitute the given values;
Therefore, the scale factor of the dilation is, 2/5

In summary, a regular octagon does not have any acute angles, while an irregular octagon can have some acute angles depending on the specific measurements of its angles.
An octagon is a polygon with eight sides. To determine the number of acute angles in an octagon, we need to understand that an acute angle is an angle that measures less than 90 degrees.
In a regular octagon (where all sides and angles are equal), each interior angle measures 135 degrees. This is because the sum of the interior angles in any octagon is given by the formula (n-2) x 180 degrees, where n is the number of sides.
In this case, (8-2) x 180 = 1080 degrees. Since all angles in a regular octagon are equal, we divide 1080 by 8 to find that each angle measures 135 degrees.
Since an acute angle measures less than 90 degrees, a regular octagon does not have any acute angles.
However, if we consider an irregular octagon (where sides and angles can have different measures), it is possible for some of the angles to be acute. The number of acute angles in an irregular octagon would depend on the specific measurements of the angles.
