The mean and the median value of the given data set is 12.62 and 6.
According to the statement
We have to find that the mean and the median of the following data.
So, For this purpose, we know that the
The mean is found by adding all of the numbers together and dividing by the number of items in the set.
And
The median is the middle number in a sorted, ascending or descending list of numbers
From the given information:
The data set are:
1,20,1, 49, 16, 5, 3, 6
Then
According mean definition,
Mean = 1+20+1+ 49+ 16+ 5+ 3+6/8
Mean = 101/8
Mean = 12.625
Then
The data set is 1,3,5,6,16,20,49.
Median = 8 terms /2
Median = 4th term
Median = 6.
So, The mean and the median value of the given data set is 12.62 and 6.

How do I solve this question?
DE is parallel to ST as ∠ EAT = ∠ AED which are alternate interior angles.
∠TAC = ∠ABC (The angle between the chord and the tangent is equal to the angle in the alternate segment)
Since, EDCB is a cyclic quadrilateral,
∠CBD + ∠CED = 180 ----- I
- ∠CED + ∠AED = 180 -----II
----------------------------------------------------
∠ CBD = ∠AED
Also, ∠ CBD = ∠ EAT( A is tangent to the circle)
So, ∠ EAT = ∠ AED ( Alternate interior angle)
So, DE || ST
Therefore, DE is parallel to ST as ∠ EAT = ∠ AED which are alternate interior angles.

Find the indicated measure
I will give brainliest to the right answer with solution
Answer:
∠ N = 10° , arc RS = 134°
Step-by-step explanation:
the measure of an inscribed angle is half the measure of its intercepted arc.
(5)
∠ N is an inscribed angle and we require arc LM
the measure of the arcs in a circle = 360°
note LN is the diameter so arc LN = 180°
Then
LM + MN + LN = 360°
LM + 160° + 180° = 360°
LM + 340° = 360° ( subtract 340° from both sides )
LM = 20°
then
∠ N = [tex]\frac{1}{2}[/tex] LM = [tex]\frac{1}{2}[/tex] × 20° = 10°
(6)
∠ Q is an inscribed angle so its intercepted arc is twice its measure
arc RS = 2 × 67° = 134°
What is the equation of the line that passes through the point ( -4, 1) and has
slope of -5/4
Answer:
y = -5/4x + 1
Step-by-step explanation:
x^2+11x+15=30
find x
After simplifying the equation we acquire the value of x as:
x = 1.225 or x = ₋12.225
Given the equation is x² ₊ 11x ₊ 15 = 30
arrange the constants on one side.
x² ₊ 11x = 30 ₋ 15
x² ₊ 11x = 15
x² ₊ 11x ₋ 15 = 0
now simplify the equation using the formula: -b±√b²₋4ac / 2a
in the equation we have the values for a = 1 , b = 11 and c = ₋15
substitute the values and get the value of x.
= ₋11 ± √(11)² ₋ 4(1)(₋15) / 2(1)
= ₋11 ± √121 ₊ 60 / 2
= ₋11 ± √181 / 2
= ₋11 ± 13.45 / 2
= ₋11 ₊ 13.45 / 2 or ₋11 ₋ 13.45 / 2
= 2.45/2 or ₋24.45/2
= 1.225 or ₋12.225
Therefore x value is 1.225 or ₋12.225
