Answer:
The population parameter of this study is the population mean.
Step-by-step explanation:
A population parameter is a numerical measure representing a certain characteristic of the population. For example, population mean, population variance, population proportion, and so on.
The population parameter is computed using all the values of the population.
The population parameter can be estimated using the sample statistic. If the value of the population parameter is not known, then a random sample of large size, say <em>n</em> ≥ 30 can be selected from the population and the statistic value can be computed. This statistic value is considered as the point estimate of the parameter. It is also known as the unbiased estimator of the parameter.
In this case the survey involved sampling of 1500 Americans to estimate the mean dollar amount that Americans spent on health care in the past year.
The sample selected is used to compute the sample mean dollar amount that Americans spent on health care.
So, the population parameter of this study is the population mean.
Answer:
Step-by-step explanation:
as Area of triangle is=1/2 base*height
Given
area=70
height=h=8
base lenght=?
put values in above formula for unkown
70=1/2 (8*b)
70=4*b
b=70/4
b=17.5 units

First, take off 4 feet of Stacy's rope, which is 19. (23-4=19). Then, divide 19 by 3. It should equal 6.3...
Answer:
for the first picture: less than zero (the slope is negative because it's going down)
for the second picture: slope is greater than 1 (the slope is positive because it's going up)
for the third picture: slope is greater than 1 (the slope is positive because it's going up)
for the fourth picture: slope is 0 (it's a horizontal line)
