Answer:

Descriptive Statistics

Step-by-step explanation:

There are mainly two types of Statistics:

1) Descriptive Statistics

Descriptive statistics provide simple summaries about the sample and the measures. When using descriptive statistics you are simply describing what the data shows.

2) Inferential Statistics

On the other hand, inferential statistics try to reach conclusions that extend beyond the immediate data alone.

In this case the decision made was based on the "90% of the taste testers preferred", and no more than that.

translate into an algebraic expression: b is decreased by 40% and decreased again by 40% . What is the result ?
MrMuchimi

Answer:

The result is 0.36b

Step-by-step explanation:

Here. we want to translate the wordings into an expression of algebra.

Firstly, we decrease b by 40%

40% is same as 40/100 = 0.4

So decreasing b by 40% = b-0.4(b) = b-0.4b = 0.6b

Now we want to decrease 0.6b by another 40%

= 0.6b -0.4(0.6b)

= 0.6b - 0.24b

= 0.36b

362.50 = 10.50x + 100

362.50 = 10.50x + 100

262.50 = 10.50x

25 = x
