The measurement of angle L = 50°.
Solution:
The given image is a rectangle.
The measurement of ∠A = 25°
The measurement of ∠B = 25°
ABC is a triangle.
Sum of the interior angles of the triangle = 180°
⇒ m∠A + m∠B + m∠C = 180°
⇒ 25° + 25° + m∠C = 180°
⇒ 50° + m∠C = 180°
⇒ m∠C = 180° – 50°
⇒ m∠C = 130°
Sum of the adjacent angles in a straight line = 180°
⇒ m∠C + m∠L = 180°
⇒ 130° + m∠L = 180°
⇒ m∠L = 180° – 130°
⇒ m∠L = 50°
Hence the measurement of angle L = 50°.
Answer:
a. 1965
b. 8 years
Step-by-step explanation:
For answers to questions like these it can work to consider the smallest possible dataset.
<h3>Dataset</h3>
For our purpose, consider the 9 years/values to be averaged to be ...
1, 2, 3, 4, 5, 6, 7, 8 ,9
<h3>Observations</h3>
a. The center value of the data set is 5. Its number is 5-1=4 more than the first one.
The first centered value is from the year 1961 +4 = 1965.
b. The 4 values at the beginning, and the 4 values at the end do not have a corresponding "average" value. That is, 4+4 = 8 values in the series are lost with respect to the number of average values.
8 years of values are lost.
Question 5 and 6 are the same.
Answer:
6
Step-by-step explanation:
20 x 0.3 = 6
