Answer:
There are 6 dimes and 9 quarters.
Step-by-step explanation:
Represent the number of dimes and the number of quarters by d and q.
Then d + q = 15, or q = 15 - d.
Also, ($0.25)q + ($0.10)d = $2.85, or 5q + 2d = 57.
Substituding 15 - d for q, we get 5(15 - d) + 2d = 57, or
75 - 5d + 2d = 57, or
75 - 3d = 57, or
3d = 18. Thus, there are 6 dimes. Since q = 15 - d, q = 15 - 6 = 9.
There are 6 dimes and 9 quarters.

Answer:
Each of the bold numbers is a statistic.
Step-by-step explanation:
In statistical analysis, observations may either be from a sample or from a population. Samples are smaller subsets a population and hence, if chosen randomly forms a good representative of the population data.
Hence, numerical characteristics of observation which forms a population are called PARAMETER. While numerical characteristics of a given sample are called STATISTIC.
From the scenario given above, 128,000 people were interviewed, this represents a sample from the population and not the entire population. Hence, all numerical characteristic or attribute derived from the sample of 128,000 interviewees will be a statistic.
Answer:
I agree
Step-by-step explanation:
1>m just states that 1 is greater than the variable
m<1 States that the variable is less than 1
They both say that the variable is less than 1 so that basically mean they're the same
