Answer:

Coefficient of x = -9.9 ;

Coefficient of x = 75

Coefficient of y = 275

Step-by-step explanation:

Given :

0.8 (2x + x) + 3(7 - 4.1x) = __x + 21

A geometric sequence has an initial value of 2 and a common ratio of 3. Which formula would be more practical to use if you were looking find the value of the 19th number in the sequence?

Answers

Answer:

19th term = ar^18

19th term = 774,840,978

Step-by-step explanation:

First term, a = 2

Common ratio, r = 3

nth term of a geometric sequence = ar^(n-1)

19th term = ar^(19-1)

19th term = ar^18

= 2 × 3^18

= 2 × 387,420,489

= 774,840,978

19th term = 774,840,978

The sample of the assigned reading likely to be biased and convenience sample.

What is probability?

probability is the ratio of the number of favorable outcomes and the total number of possible outcomes. The chance that a particular event (or set of events) will occur expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%.

Given:

Alana skimmed the first 17 pages from each of the books

assigned in her literature class. Each assigned book has an equal number of pages.

According to given question we have

A biased estimator is one that deviates from the true population value. A biased sample can still be useful if the nature of the bias and how much of a bias exists is known.

An unbiased estimator is when a value from a sample is the same as the actual value of a population parameter.

The sample is not chosen at random, the inherent bias in convenience sampling means that the sample is unlikely to be representative of the population being studied. This undermines your ability to make generalizations from your sample to the population you are studying.

Therefore, the sample of the assigned reading likely to be biased and convenience sample.
