I think the independent variable is the number of people and the dependent is the wait time. I see it as the wait time DEPENDS on how many people are in line. This one is kinda confusing tho

What is an equation of a parabola with a vertex at the origin and directrix x=4.75?

patriot [66]

An equation for the parabola would be y²=-19x.

Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form

(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.

Beginning with the directrix:

x=h-p=4.75
h-p=4.75

Since the vertex is at (0, 0), this means h=0 and k=0:

0-p=4.75
-p=4.75
p=-4.75

Substituting this into the standard form as well as our values for h and k we have:
(y-0)²=4(-4.75)(x-0)
y²=-19x

Which of the options is true

(a): Female more likely in online only courses

In online courses, we have:

$Female = 7000$

$Male = 2000$

By comparison:

$7000 > 2000$

Hence, this statement is true

Select three ratios that are equivalent to 11:111:111, colon, 1.<br> Choose 3 answers:

kirill115 [55]

The three ratios that are equivalent to the given ratio are options B, C and E.

<h3>How to determine the equivalent ratios?</h3>

In order to determine the ratios that are equivalent to the given ratio, we would evaluate by dividing each of them by their respective denominator value:

(11:111:111)/1 = 11:111:111.

For choice A, we have:

1:111:111/11 = 1/11:111:111 (not equivalent).

For choice B, we have:

22:222:222/2 = 11:111:111. (equivalent).

For choice C, we have:

55:555:555/5 = 11:111:111. (equivalent).

For choice D, we have:

9:999:999/99 = 1/11:111:111 (not equivalent).

For choice E, we have:

110:1110:1110/10 = 11:111:111. (equivalent).
