A line is parameterized by x=2+6???? and y=4+3????. (a) Which of the following points are on the section of the line obtained by

restricting ???? to nonnegative numbers (for each, enter Y if the point is on the section, and N if not)? (−28,−11) : (8,7) : (26,16) : Then, give one more point that is on the section of the line obtained by this restriction: (b) What are the endpoints of the line segment obtained by restricting ???? to −2≤????≤1? left endpoint : right endpoint : (c) How should ???? be restricted to give the part of the line above the x-axis (give your answer as an interval for ????, for example, (3,8) or [-2,Inf))? ???? must be in :

Answer:

No, yes, yes

(-28,-11) and (8.7)

[tex][\frac{-4}{3} ,\infty)}[/tex]

Step-by-step explanation:

Given that a line in two dimension is parametrized by

x=2+6t \\y = 4+3t

a) If t is non negative, then (-28,-11) cannot lie on that part

(-28,-11) No because t =-5

(8,7) yes because t =1

(26,16) yes because t = 4

b) when t lies between -2 and 1

we have left end point as

x=2+6(-2) = -10\\y = 4+3(-2) = -2\\

(-10,-2) is left end point

Right end point is when t =1 i.e.

(8,7)

c) when the points should be above x axis, y should be non negative

i.e. y=4+3t\geq 0\\t\geq

So t should lie in the interval

[\frac{-4}{3} ,\infty)}

Katarina [22]

Answer:  Mode

<u>Step-by-step explanation:</u>

The given data set is:    10, 10, 12, 13, 15

Mean is the average - find the sum of the data set and divide by the number of terms in the set: \dfrac{10+10+12+13+15}{5} =\dfrac{60}{5}=12

Mean = 12

Median is the middle term (when the data set is ordered from least to greatest).

Median = 12

Mode is the term that appears the most.

Mode = 10

Since you want to show that the prices are low, you would choose the lowest value.  10 is lower than 12, so the Mode is lower than either the Mean or the Median.

Xavier, Yessie, and Zorro each choose a different favorite positive fraction. Each fraction is in simplest form. Yessie's fracti
ad-work [718]
Let Xavier's favourite fraction be a/b, Yessie's favourite fraction = b/a and Zorro's favourite fraction = c/d,

c/d x a/b = 12/35 . . . . . . . . (1)
c/d x b/a = 15/7 . . . . . . . . (2)

(1) x (2) = c/d x a/b x c/d x b/a = 12/35 x 15/7
 c^2 / d^2 = 36/49
c^2 = 36
c = 6
d^2 = 49
d = 7

Xaviers favourite fraction = 12/35 / 6/7 = 2/5
Yessies favourite fraction = 5/2
Zorro favourite fraction = 6/7
