Nellie is analyzing a quadratic function f(x) and a linear function g(x). Will they intersect?
Answers
Answer: yes choice B
Step-by-step explanation:
g(x) has -5 slope
y - g(-1) = -5(x +1)
y -5 = -5x -5
y = -5x
f(x) = xx/2 +2
Xx/2 +2= -5x
Xx/2 +5x +2 = 0
Xx + 10x +4 =0
Solutions: -5 + root(100 -16)/2
And -5 - root(84)/2
Both intersection look like in negative x values

With a large number such as 150, I sometimes find it helpful to factor all possible combinations.
150

-1 × -150 ll -1 - 150 = -151
-2× -75 ll -2-75 = -77
-3× -50 ll -3-50 = -53
-5× -30 ll -5-30 = -35
-6× -25 ll -6-25 = -31
-10× -15 ll -10-15 = -25
The numbers are -6 and -25
-6 -25 = -31
-6 × (-25) = 150

Final answer:
A fraction between 3/4 and 4/5 can be found using averaging. By converting these fractions to decimal equivalents, adding them together, and dividing by 2 we get 0.775, which is equivalent to the fraction 31/40.
Explanation:
To find a fraction between 3/4 (0.75) and 4/5 (0.8), we can use an approach called averaging where we add both fractions and divide the sum by 2. Using decimal equivalents can make the calculation more straightforward. You add 0.75 and 0.8 to get a sum of 1.55, then divide by 2 to get 0.775. A fraction equivalent to 0.775 is 31/40, which is between 3/4 and 4/5.

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
