Step-by-step explanation:
Generally the appropriate conclusion is
The sample data provide little evidence to doubt that the proportion of American teenagers with hearing loss was the same in 1988-1994 as in 2005-2006.
This because the confidence intervals are very close to zero , i.e both the upper limit and the lower limit are close to zero and if we are take 0.05 as our level of significance we see that the both values of the confidence level are small to be significant
How do you Subtract 9x^2 + 22x - 46 from 12x^2 - 8x + 12.
Answers
Subtract the [tex]x^2[/tex] terms from each other, then the [tex]x[/tex] terms, then the ones without any [tex]x[/tex] whatsoever.
[tex](12x^2 - 8x + 12) - (9x^2 +22x-46)[/tex]
First, we'll subtract [tex]9x^2[/tex] from [tex]12x^2[/tex]
[tex]12x^2-9x^2- = 3x^2[/tex]
Result: [tex]3x^2[/tex]
Next, we'll subtract [tex]22x[/tex] from [tex]-8x[/tex]
[tex]-8x - 22x = -30x[/tex]
Result: [tex]-30x[/tex]
Finally, we'll subtract [tex]-46[/tex] from [tex]12[/tex]
[tex]12-(-46) = 12+46 = 58[/tex]
Result: [tex]58[/tex]
Now, we can add these 3 results together.
First, we had [tex]3x^2[/tex], then [tex]-30x[/tex], and finally [tex]58[/tex].
Thus, our subtraction of
[tex](12x^2 - 8x + 12) - (9x^2 +22x-46)[/tex]
equals
[tex]3x^2-30x+58[/tex]

Sally buys a shirt of 5.00. New York's sales tax is 8.200. What is the final price?
Show your work and explain or I report and delete answer.
Answers
Answer: $5.40
Sales tax is a price you add to every 100 cents purchased.
Sally purchased a shirt of 5.00, and New York's sales tax is 8.200.
So, we multiply 8 by 5. We get the number 40, right?
You now add 0.40 to 5.00.
The answer totals at 5.40 because 5.00 + 0.40 = 5.40.

Write an equation of the line passing through point P(−2, 6) that is parallel to the line x=−5.
Answers
Answer:
x = -2
Step-by-step explanation:
The line x = - 5 means it is a straight vertical line that has no slope. This means that the slope is undefined.
Now, for this line to be parallel to the line passing through point P(−2, 6), it means the line will be a vertical line too with the equation of form (x = a).
Thus, the equation of the line is x = -2
The equation of the line is given by:
[tex]x = -2[/tex]
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of x when y = 0.If two lines are parallel, they have the same slope.Line x = -5 is a horizontal line, thus, it's slope is undefined.
A line parallel will also be horizontal, with undefined slope.
It passes through point P(-2,6), thus, the equation of the line is:
[tex]x = -2[/tex]

I need to find the missing angle for this triangle
Answers
Answer:
44 degrees
Step-by-step explanation:
Because a right angle triangle if added all angles will=to 180 degrees
so 46+90=136
180-136=44
Answer:
44
Step-by-step explanation:
You add 46 to the 90 degree angle (right angle) and get 136. Then, because the angles of a triangle add up to 180 degrees all the time, you would do 180-136 and get 44.

What are the slopes of the perpendicular lines?
1: y=-5/2x-8
2: y=5x
3: y=3x-8
Answers
Answer:
1. 2/5
2. -1/5
3. -1/3
Step-by-step explanation:
the parpendicular slope is found by taking the original slope and finding the opposite reciprocal. so just flip the slope and make it the opposite sign
-5/2 ---> 2/5
+5/1 ---> -1/5
+3/1 ---> -1/3
1. 2/5
2. -1/5
3. -1/3
Explanation:
There are two key concepts that we have to understand in order to answer this question:
1) The given equations are organized in slope-intercept form: y=mx+b. Here’s what the variables mean:
Y= the y coordinate
M=the slope
X= the coordinate
B= the y intercept
From the given equations we can now identify the slopes as -5/2, 5 and 3.
2) Perpendicular lines have slopes that are NEGATIVE RECIPROCALS of each other.
Example: Line A has the slope 8. A line that is perpendicular to line A would have a slope of -1/8.
Example #2: Line B has the slope -2/3. A line that is perpendicular to line B would have a slope of 3/2 (two negatives make a positive).
Now that we understand these two concepts, we need to look at the slopes of the given lines and determine their negative reciprocals to find the slopes of their perpendicular lines.
1. y=-5/2x-8
We can see that -5/2 is in the place of “m” in y=mx+b. The negative reciprocal of -5/2 is 2/5, so therefore, the slope of the line perpendicular to y=-5/2x-8 is 2/5.
2. y=5x
There is no “b” value in this equation, but we can still identify 5 as “m”. The negative reciprocal of 5 is -1/5, so therefore, the slope of the line perpendicular to y=5c is -1/5.
3. y=3x-8
The negative reciprocal of 3 is -1/3, so therefore, the slope of the line perpendicular to line y=3x-8 is -1/3.
I hope this helps! Please comment if you have any questions.
