Well by looking at the equation I would say it already tells you the slope. The slope would be -1,500x.
It would be set up like, y=-1,500x+16,500
Hope that helps! (:
Answer:
35.3 years
Step-by-step explanation:
Given :
In 1980 the median age of a resident of the united state was 30 years.
By 2000 the median age had increased 5.3 years.
Solution :
The median age the median age of a resident of the united state = 30 years
Since the median age had increased 5.3 years in 2000
Thus , the median age of a resident of the United States in year 2000 = 30+5.3 = 35.3 years
Hence the median age of a resident of the United States in year 2000=35.3 years
Answer:
The margin of error for constructing a 95% confidence interval on the population mean income before taxes of all consumer units in the U.S is 1406.32.
Step-by-step explanation:
We are given that according to a survey of 500, the mean income before taxes of consumer units (i.e., households) in the U.S. was $60,533 with a standard error of 717.51.
Margin of error tells us that how much our sample mean value deviates from the true population value.
<u></u>
<u>Margin of error is calculated using the following formula;</u>
Margin of error =
where, = level of significance = 1 - confidence level
= 1 - 0.95 = 0.05 or 5%
Standard of Error = = 717.51
Now, the value of z at 2.5% level of significance () is given in the z table as 1.96, that means;
Margin of error =
= = 1406.32
Hence, the margin of error for constructing a 95% confidence interval on the population mean income before taxes of all consumer units in the U.S is 1406.32.
Some objected to slavery on moral grounds, believing that it violated christian teachings , while others simply did not want to complete economically with slave-owners.
Answer:
37.8 metre
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW;
Linda shoots an arrow at a target in an archery competition. The arc of the arrow can be modeled by the equation y= -0.02x to the power of 2 + 0.65+4 where x is the horizontal distance (in meters) from Linda and y is the height (in meters) of the arrow. How far from Linda does the arrow hit the ground? Round to the nearest tenth.
From the question, we are told that the equation that modelled the arc is
y=-0.02x²+0.65x+4
From the question, "x" in the equation=
the horizontal distance (in meters
While "y" in the equation = the height (in meters) of the arrow.
We can find the value of x and y by equating to zero(since arrow hits the ground when its height (y) is zero) then solve the quadratic equation using quadratic formula
y=-0.02x²+0.65x+4=0
We have, x=37.79 or -5.29
The negative x= -5.29 can be described as been at the back of Linda,
But the distance is of positive value, therefore, the arrow hit the ground at 37.8 metre from Linda after Rounded to the nearest tenth.
