Answers
Answer:
No because function usually go through the origin and are in a straight line.
Find the following.
f(x) = x + 8, g(x) = x − 8
(a) (f + g)(x) =
(b) (f − g)(x) =
(c) (fg)(x) =
(d) (f/g)(x) =
What is the domain of f/g?
(Enter your answer using interval notation.)
Answers
Answer:
(f + g)(x) = 2x
(f - g)(x) = 16
(fg)(x) = [tex]x^{2}[/tex] - 64
(f/g)(x) = (x + 8)/(x - 8) Domain: x < 8 ∪ x > 8
Step-by-step explanation:
(f + g)(x) = f(x) + g(x) = x + 8 + x - 8 = 2x
(f - g)(x) = f(x) - g(x) = x + 8 - (x - 8) = x + 8 - x + 8 = 16
(fg)(x) = f(x)g(x) = (x + 8)(x - 8) = [tex]x^{2}[/tex] - 64
(f/g)(x) = f(x)/g(x) = (x + 8)/(x - 8)
x - 8 ≠ 0
x ≠ 8
Domain: x < 8 ∪ x > 8
A confidence level of 95% means: 95% of the time, sample percentages will fall above the mean. 95% of the time, population data will fall between 149.61 and 150.39. the mean of 95% of the adults in the sample was 150.
Answers
Answer:
B
Step-by-step explanation:
95% of the time, population data will fall between 149.61 and 150.39.
A confidence level of 95% means 95% of the time, population data will fall between 149.61 and 150.39. The correct answer would be an option (B).
What is the sample?A sample is a subset of data drawn from a larger population by a researcher using a predetermined selection process. These components are referred to as sample points, sampling units, or observations.
The second statement, "95% of the time, population data will fall between 149.61 and 150.39," is more accurate in terms of what a 95% confidence level implies.
When you conduct a sample survey, you can calculate a confidence interval, which is an estimate of the range of values that the population parameter is likely to fall within.
If the confidence level is 95%, it means that if you were to repeatedly sample the population and construct a confidence interval each time, 95% of those intervals would contain the true population parameter.
Thus, the correct answer would be option (B).

P is the point (16,9) and Q is the point (22. 24).
(a) Find the equation of the line perpendicular to PQ that passes through the point (5, 1).
Give your answer in the form y=mx+c.
(b) N is the point on PQ such that PN=2NQ. Find the co-ordinates of N.
Answers
Answer:
see explanation
Step-by-step explanation:
(a)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (P(16, 9) and (x₂, y₂ ) = Q(22, 24)
[tex]m_{PQ}[/tex] = [tex]\frac{24-9}{22-16}[/tex] = [tex]\frac{15}{6}[/tex] = [tex]\frac{5}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{5}{2} }[/tex] = - [tex]\frac{2}{5}[/tex] , then
y = - [tex]\frac{2}{5}[/tex] x + c ← is the partial equation
To find c substitute (5, 1) into the partial equation
1 = - 2 + c ⇒ c = 1 + 2 = 3
y = - [tex]\frac{2}{5}[/tex] x + 3 ← equation of perpendicular line
(b)
Given PN = 2NQ , then N sections PQ in the ratio 2 : 1
Using the Section formula to find coordinates of N
N = ( [tex]\frac{16(1)+22(2)}{1+2}[/tex] , [tex]\frac{9(1)+24(2)}{1+2}[/tex] )
= ( [tex]\frac{16+44}{3}[/tex], [tex]\frac{9+48}{3}[/tex] )
= ( [tex]\frac{60}{3}[/tex], [tex]\frac{57}{3}[/tex] )
= (20, 19 )

Find the measure of b and a. (type the number of the angle measure ONLY)
Answers
Answer:
Step-by-step explanation:
A straight line has 180 degrees.
43 + b + 50 = 180 Collect like terms
b + 93 = 180 Subtract 93
b = 180 - 93
b = 87
a + b + 75 = 180 All triangles have 180 degrees.
a + 87 + 75 = 180 Combine like terms
a + 162 = 180 Subtract 162 from both sides
a = 180 - 162
a = 18

Sorry if it's wrong.
Answer:
Step-by-step explanation:
Remark
First of all, you need a regular polygon, otherwise the question can have all sorts of interior angles. The standard way to solve this is set up an equation that looks like this.
(n - 2)*180 = 1080 Divide by 180
(n - 2) = 1080/180
n - 2 = 6 Add 2 to both sides.
n = 6 + 2
n = 8
Conclusion
So an 8 sided figure has 8 interior angles that add up to 1080 if the 8 sided figure is regular.
