Hi hope your okay the answer is d = -7
Answer:
The answer is below
Step-by-step explanation:
The procedure of selecting a sample is thus called, fulfilling two fundamental properties:
-All individuals in the population have the same probability of being elected.
-All samples of the same size are equally likely.
From a mathematical point of view, simple random sampling is performed assuming that the population has infinite elements. In practice, it is often the case that the populations to be considered have a very large number of elements, which can be compared to a situation with infinite elements.
Yes, it is possible to sample data instances using a distribution different from the uniform distribution.
In excel, do the following to obtain a sample dataset.
E.g. to create a 5 element sample from the standard normal distribution, place the formula = NORM.S.INV (RAND ()) in cell A1, highlight the range A1: A15 and press Ctrl-D.
Step-by-step explanation:
For no. 11
13x + 15 = 19x - 9 ( being opposite sides of parallelogram)
19x - 13x = 15 + 9
6x = 24
x = 4
Also,
4y + 7 ° + 10y - 37° = 180° { being co-interior angles }
14y - 30° = 180°
14y = 210°
y = 210° / 14
y = 15°
For no. 12
5x + 38° = 8x - 19° { being opposite angles of parallelogram }
8x - 5x = 38° + 19°
3x = 57°
x = 19°
Hope it will help :)
