Answer:
y = -2x + 9
Step-by-step explanation:
Let's start from the -2x, the slope is -2. The x is basically what says, this is the slope. The plus nine is the y-intercept. If you think in graph terms (which is how you solve this problem) you will see that on the y-axis the line will intercept at the 9. The every x integer it goes down it goes that times two. For example, if you go sideways 1 spot, the line will be at y=11.

Answer:
7
Step-by-step explanation:
f(g(2))
f(x+4) and you would replace x with two, so you would get
f(2+4) = f(6)
You would then plug in 6 for the x in the f(x) equation:
2(6) - 5 = 12-5 = 7
Simplify the expression: 4(–6p − 2)

Use traces to sketch the surface. x2 = y2 + 5z2
Answer:
when k > 0 the traces parallel to the yz plane is an ellipse
The traces parallel to the xz plane are parabolas and they open in positive x- axis direction
The traces parallel to the xy plane are parabolas that open in the positive x-axis direction
Step-by-step explanation:
Given surface : [tex]x^2 = y^2 + 5z^2[/tex]
To determine the traces of the given equation we will have to make some assumptions and the assumption is
let x = k
[tex]k^2 = y^2 + 5z^2[/tex]
when k > 0 the traces parallel to the yz plane is an ellipse
let y = k
[tex]x^2 = k^2 + 5z^2[/tex]
The traces parallel to the xz plane are parabolas and they open in positive x- axis direction
Let z = k
[tex]x^2 = y^2 + 5k^2[/tex]
The traces parallel to the xy plane are parabolas that open in the positive x-axis direction
with the given traces The surface can be sketched

The midpoint of AB is M=(3, 1). One endpoint is A=(-1, -1).
Find the coordinates of the other endpoint, B.
Answer:
(7, 3)
Step-by-step explanation:
Given segment AB, where:
A = (-1, -1)Mid point
M = (3, 1)Point B = (x, y)As per mid point formula:
(-1+x)/2 = 3 ⇒ -1 + x = 6 ⇒ x = 6+ 1 = 7(-1 + y)/2 = 1 ⇒ -1 + y = 2 ⇒ y = 2 + 1 = 3So, the point B is:
B = (7, 3)Use the sample data and confidence level given below to complete parts (a) through (d).

Tyler claims that because he started painting first he will finish painting his side of the fence before Benito finishes painting his side. Is this true? Explain
Answer:
but
Step-by-step explanation:
yrge sksue dnd djd d d. r e g g h a s. v j u r d. d c g y t
Tyler's claim about finishing his painting first is False because it will take Benito 10 minutes while Tyler will require over 11 minutes to finish up his painting despite starting before Benito.
Size of fence = 150 feet
Benito's rate = 15 ft/min
Tyler's rate = 11 ft/ min
Size already painted by Tyler when Benito started = 39/2 = 19.5 ft
Portion of fence left for Tyler to paint when Benito started = (150 - 19.5) = 130.5 feets
Time required for Tyler to finish :
Time required = 130.5 ÷ 11 = 11.863 minutes
Time required for Benito to finish :
Time required = 150 ÷ 15 = 10 minutes
Time required for Benito to complete his painting is lesser than Tyler's (10 < 11.863)
Hence, Tyler's claim is False

A study is conducted to assess the smoking behaviors of high-school seniors. A random sample of 8 seniors is selected and each student is asked the number of cigarettes consumed on a typical day. The (sorted) sample is: 0 0 3 4 5 8 10 18. If 18 is replaced with 20, then select all that apply:
Sample IQR will change
Range, IQR, and standard deviation will remain the same
Sample range will change.
Sample standard deviation will change
Answer:
Sample range will change
Sample Standard deviation will change
Step-by-step explanation:
Given the sorted sample : 0,0,3, 4,5,8,10, 18
n = number of observations
Sample range : ( 18 - 0) = 10
Upper quartile (Q3) = 3/4(n+ 1) = 3/4(9) th term
Q3 = 27/4 = 6.75th term
(8 + 10) / 2 = 18/ 2 = 9
Lower quartile (Q1) = 1/4(n + 1) = 9/4 th term
2.25th term = 0+3 = 3/2 = 1.5
Interquartile range = 9 - 1.5 = 7.5
Standard deviation = 5.976 (using calculator)
If 18 is replaced by 20:
0,0,3, 4,5,8,10, 20
Range = (20 - 0). = 20
Upper quartile (Q3) = 3/4(n+ 1) = 3/4(9) th term
Q3 = 27/4 = 6.75th term
(8 + 10) / 2 = 18/ 2 = 9
Lower quartile (Q1) = 1/4(n + 1) = 9/4 th term
2.25th term = 0+3 = 3/2 = 1.5
Interquartile range = 9 - 1.5 = 7.5
Standard deviation = 6.563 (using calculator)
