Answer:
a) 495 cents
b) 25 words
c) 1174.7 cents
Step-by-step explanation:
a) The cost is equal to 28 x 15 + 75 which equals 420 + 75 which equals 495 cents.
b) (800 cents - 75) divided by 28
= 725 / 28
= 25.9
Since you cannot have 0.9 of a word it is rounded down to 25.
c) 22 words in the first week will cost 22 x 28 + 75 = 616 + 75 = 691 cents
In the second week it will cost 30% less which means it will only cost 70% of the ordinary price. Therefore the second week will cost:
0.7 x 691 = 483.7 cents
Total = 483.7 + 691
= 1174.7 cents
Hope this helps :)

Answer:
24 crates
Step-by-step explanation:
The usable load capacity for 40-kg crates is ...
1050 kg - 82 kg = 968 kg
The number of 40-kg crates that can be loaded in a trailer with this capacity is ...
floor(968/40) = floor(24.2) = 24 . . . . crates
_____
The function floor(n) gives the greatest integer less than or equal to n. For positive numbers, it drops the fraction.

B-The purpose of (1) inferential (2) descriptive statistics is to use the limited data from a sample as the basis for making general conclusions about the population.
Answer:
A-The purpose of (2)descriptive statistics is to simplify the organization and presentation of data.
B-The purpose of (1) inferential statistics is to use the limited data from a sample as the basis for making general conclusions about the population.
Step-by-step explanation:
The descriptive statistics is used to make large data presentable into usable short forms, without which it would look impossible to solve. We draw a sample from the population and find its mean or draw histograms for the frequency distributions. This is descriptive statistics.
The inferential statistics is used to make inferences and conclusions from limited data given from a population. We do the hypothesis testing for the random samples obtained from larger populations. The hypothesis tests or the confidence intervals help us decide whether the rseults are accepted or not.
Descriptive statistics is used to summarize and organize data from a sample, such as providing the average or frequency of a variable. Inferential statistics, on the other hand, uses this sample data to make broad generalizations about the population.
The two major categories of statistical techniques are inferential statistics and descriptive statistics. The general purpose of descriptive statistics is to simplify the organization and presentation of data. They provide simple summaries about the sample and the measures. For example, we may want to know the average, maximum, minimum, or frequency of some variable.
On the other hand, inferential statistics involve using the limited data from a sample as the basis for making general conclusions about the population. They also include the theory of hypothesis testing, which is a method for testing statistical results. For example, inferential statistics would be used to determine if a difference observed between groups is a real one or if it might have happened by chance in this study.
