Answer: $69811
Step-by-step explanation:
Given : A survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten years, but with a smaller percentage of participants.
One of these surveys estimates with 90% confidence that the mean household income in the U.S. falls between $69,702 and $69,920. (1)
We know that the confidence interval is given by :-
Point estimate of mean ± Margin of error
From (1) , we have
Point estimate for mean -Margin of error = $69,702 (2)
Point estimate for mean +Margin of error = $69,920 (3)
Add (2) and (3), we get
2 (Point estimate for mean) = $139622
Divide both sides by 2, we get
Point estimate for mean=$ 69811
Therefore , the point estimate for mean U.S. household income. = $ 69811
Final answer:
The point estimate for mean U.S. household income is $69,811.
Explanation:
The given information states that a survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten years. This survey estimates with 90% confidence that the mean household income in the U.S. falls between $69,702 and $69,920. To find the point estimate for mean U.S. household income, we can simply take the average of the lower and upper bounds of the confidence interval:
Point estimate = (lower bound + upper bound) / 2
Substituting the given values, we get:
Point estimate = ($69,702 + $69,920) / 2 = $69,811

The three consecutive integers that add up to 450 are 149, 150, and 151.
What are the consecutive numbers?
The consecutive numbers are those numbers that follow each other continuously in the order from smallest to largest numbers.
Given that the sum of three consecutive even numbers is 450
We need to find the 3rd number of the integers.
Now assume the 3 consecutive integers are x, (x+1) and (x+2)
Therefore, x+(x+1)+(x+2)= 450
Combine the like terms;
3x+3= 450
X=149
Thus the second number is 149 + 1 and the third number is 149 + 2.
Hence, the 3rd number of the integers would be 151.

Step-by-step explanation:
Which means that the first number is 149, the second number is 149 + 1 and the third number is 149 + 2. Therefore, three consecutive integers that add up to 450 are 149, 150, and 151. We know our answer is correct because 149 + 150 + 151 equals 450 as displayed above.

So applying the distributive property(Left sides) in the above expression, we get
Again applying the distributive property (Right side) in the above expression, we get
x*(y - 9) - 7*(y - 9)
x*y - x*9 - 7*y -7*(-9)
xy - 9x - 7y + 63
