Answer:

a) y = 7 - x

b) m = 24 ÷ d

c) p = 10w + 7

d) y = 3x - 5

e) b = a^2 + 7

f) p = 50 - 8n

Step-by-step explanation:

a) x - values are 4, 5, 6, 7

    y- values are 3, 2, 1, 0

y = 7 - x


b) d values are : 1, 2, 3, 4

   m values are : 24, 12, 8, 6

m = 24 ÷ d

c) w values are : 0, 1, 2, 3

p value are : 7, 17, 27, 37

p = 10w + 7

d) x values are : 0, 1, 2, 3

y values are: -5, -2, 1, 4

y = 3x - 5

e) a values are : -4, -3, -2, -1

b value are : 23, 16, 11, 8

b = a^2 + 7

f) n values are : 0, 1, 2, 3

p values are : 50, 42, 34, 26

p = 50 - 8n

Thank you.

A student working on a report about mathematicians decides to find the 98% confidence interval for the difference in mean age at
balandron [24]

Answer:

The entire population is measured in both cases, so the actual difference in means can be computed and a confidence interval should not be used.

Step-by-step explanation:

A student working on a report about mathematicians decides to find the 98% confidence interval for the difference in mean age at the time of math discovery for Greek mathematicians versus Egyptian mathematicians. The student finds the ages at the time of math discovery for members of both groups, which include all Greek and Egyptian mathematicians, and uses a calculator to determine the 98% confidence interval based on the t distribution, <u>the entire population is measured in both cases, so the actual difference in means can be computed and a confidence interval should not be used.</u> There is no as such explanation of this scenario, its just the answer mentioned above.

A city planner is studying the need for affordable housing in the city's Urban Planning Department. He learned from the census o
goldfiish [28.3K]

Answer:

Population = 75,342 households

Sample = 400 randomly selected households

The percentage who live in a single household unit = Parameter

The average of 2.9 person per household of all households in the city = parameter

The $65,000 median family income of all the households in the city = Parameter

Step-by-step explanation:

The population refers to all the entire elements, observations or subject which fits into a particular study. In the scenario above, the entire household in the city of study. That is, the 75,342 households.

The sample is the subset of the population which is a smaller set of observation meant to be representative of the larger population. The sample here is the 400 randomly selected households.

Parameter differs from statistics in that numerical estimates or calculations obtained from the population is called the parameter while the numerical characteristics derived from the sample is called statistic.
