The question is asking for the percentage of absences each week given the percentage of attendance. We can calculate [tex]100\%-Attendance[/tex] (attendance is in percentage form) to find the percentage of people that were absent during each get-together:
Week 1: [tex]100\%-86\%=14\%\\[/tex]
Week 2: [tex]100\%-82\%=18\%[/tex]
Week 3: [tex]100\%-98\%=2\%[/tex]
Week 4: [tex]100\%-91\% = 9\%[/tex]
Week 5: [tex]100\%-77\% = 23\%[/tex]

The following two-way table shows the data for the students of two different grades in a school:
Member of Public Library Not Member of Public Library Total
Grade 6
25
3
28
Grade 7
23
7
30
Total
48
10
58
Based on the relative row frequency, the students of which grade are more likely to be members of the public library?
The students of both grades are equally likely to be members of the public library
No conclusion can be drawn about the chances of a student being a member of the public library
Grade 7
Grade 6
Answer:
6th
Step-by-step explanation:
the chart says not, 7th has majority
The students of grade 6 are more likely to be members of the public library
What is probability?Probability is the ratio that shows the likelihood an event will occur or not from a given set of events.
The students of which grade are more likely to be members of the public library are determined below:Grade 6:
The total number of students who are a member of the public library = 25
The total number of students = 28
P(grade 6 students who are members of the public library.) = 25/28
= 0.892
Grade 7:
The total number of students who are a member of the public library = 23
The total number of students = 30
P(grade 6 students who are members of the public library.) = 23/30
= 0.767
We can see that grade 6 students are more likely to be members of the public library.
Therefore, we have found that the students of grade 6 are more likely to be members of the public library.

Write a system of linear equations for the graph below.
We need to determine the equation of both lines first.
Line 1: y = -2x + 3Line 2: y = -1/3x - 2Now that we know the equations, we can set up a system of equations for this graph where both equations are in standard form.
Line 1:
[tex]y = -2x + 3\\\\2x + y = 3[/tex]
Line 2:
[tex]y = -\frac{1}{3}x - 2\\\\\frac{1}{3}x + y = -2[/tex]

Isabela tem dois dados de um jogo, conforme a figura a seguir: O dado 1 é numrado de 1 a 6 e o dado 2 é numerado de 1 a 8. Isabela lançou os dois dados simultaneamente. A probabilidade de que a soma obtida pelos dois números sorteados seja maior que dez é de, aproximadamente: A) 14% B) 15% C) 21% D) 27% E) 29%
Responda:
C) 21%
Explicação passo a passo:
Dado que:
Dado 1: rotulado de 1 - 6
Dado 2: rotulado de 1 - 8
Espaço amostral :
8 * 6 = 48
Probabilidade = resultado necessário / resultados possíveis totais
Resultado necessário = soma maior que 10 = 10
Resultados totais possíveis = 48
P (soma> 10) = 10/48
P (soma> 10) = 0,208333
20,8333 * 100%
= 20,833%
= 21%
system by elimination
2x - y = -3
-2x - 8y = 12
Answer:
x= -2 y= -1
Step-by-step explanation:
stack the 2 equations on top of each other and add them together
the 2x and -2x cancel out and you are left with -9y=9
this gives you y= -1
you plug the y value into one of the equations:
2x - (-1) = -3
2x+1 = -3
2x= -4
x= -2

Write the following linear function in slope intercept form.
Group of answer choices
y=-2x+4
y=-4x+2
y=4x+2
y=2x+4
Answer: y = 2x + 4
suppose: the equation of the line is y = ax + b(a ≠ 0)
the line passes through (0;4) and (-2;0) => 4 = b
-2a + b = 0
⇔ b = 4
a = 2
=> y = 2x + 4

Answer:

Step-by-step explanation:
i think im not sure tho
does anyone know the answer to this question.....0.5x + 1.75 = 10
Answer:
x = 16.5
Step-by-step explanation:
0.5x + 1.75 = 10
Subtract 1.75 from both sides:
0.5x = 8.25
Divide both sides by 0.5
x = 16.5
Check your work!
0.5(16.5) + 1.75 = 10
8.25 + 1.75 = 10
10 = 10
x = 16.5
