Every day, two student council members are randomly chosen to read the morning announcements. Students cannot be chosen more tha
Nesterboy [21]

<u>Complete Question</u>

The table shows the number of grade 7 and grade 8 students on the student council at Jeremy’s school.

Number of Students

  • Grade 7 - 17
  • Grade 8 - 34

Answer:

C- The number of outcomes representing each grade level does not change after the first student is chosen.

Step-by-step explanation:

The ratio of Grade 7 students to Grade 8 students is:

17:34

This written in reduced form is 1:2

Therefore, initially, the six parts of the cube can be divided into the ratio 2:4 which Jeremy did.

However, after the first selection of a student, the ratio of Grade 7:Grade 8 student changes since the same student cannot be chosen more than once.

Therefore the cube rolls represent only the first student choice and may not be accurate for subsequent rolls.

The correct option is C.

What relations are functions
Inessa05 [86]

The requirement is that every element in the domain must be connected to one - and one only - element in the codomain.


A classic visualization consists of two sets, filled with dots. Each dot in the domain must be the start of an arrow, pointing to a dot in the codomain.


So, the two things can't can't happen is that you don't have any arrow starting from a point in the domain, i.e. the function is not defined for that element, or that multiple arrows start from the same points.


But as long as an arrow start from each element in the domain, you have a function. It may happen that two different arrow point to the same element in the codomain - that's ok, the relation is still a function, but it's not injective; or it can happen that some points in the codomain aren't pointed by any arrow - you still have a function, except it's not surjective.

Peter spent half the money on his gift card and coffee and he loaded another $10 on the gift card how much was on the gift card
cestrela7 [59]

Answer:

$80 was on the gift card to begin with

Step-by-step explanation:

Let the initial money be x

Peter spent (1/2)*x

Peter added 10

<em>Before adding more money on the gift card Peter had x -(1/2)x left on the gift card which is (1/2)x</em>

<em>After loading more money Peter had (1/2)x + 10</em>

(1/2)x = 40 <em>(money spent by Peter)</em>

x/2 = 40

x = 80
