A sample of 100 people is classified by gender (male/female) and by whether they are registered voters. The sample consists of 8
uysha [10]

Answer:

12

Step-by-step explanation:

Given :

                                    Male         Female        Total

Registered                                                          60

Non registered                                                   40

Total                          20                  80    

Solution :

N= 100

Formula of expected frequency = E_{ij}=\frac{T_i \times T_j}{N}

E_{ij}= expected frequency for the ith row/jth columm.

T_i = total in the ith row

T_j= total in the jth column

N = table grand total.

So, using formula  E_{11}=\frac{T_1 \times T_1}{100}

E_{11}=\frac{60 \times 20}{100}

E_{11}=12

E_{12}=\frac{T_1 \times T_2}{100}

E_{12}=\frac{60 \times 80}{100}

E_{12}=48

E_{21}=\frac{T_2 \times T_1}{100}

E_{21}=\frac{40 \times 20}{100}

E_{21}=8

E_{22}=\frac{T_2 \times T_2}{100}

E_{22]=\frac{80 \times 40}{100}

E_{22}=32

Expected frequency table

                                    Male         Female        Total

Registered                  12                  48            60

Non registered           8                   32             40

Total                           20                  80    

So, the expected frequency for males who are registered voters are  E_{11}=12

Is this answer correct
Tju [1.3M]

Answer: I think it’s (4,0)

Step-by-step explanation: because it says (0,0) is the center point, you’d rotate by 180 degrees and move it down 3 in order for (0,0) to indeed be the center

What is the value of 5n-3 when n=5?
joja [24]

Answer:

22

Step-by-step explanation:

We are given the expression:—

\displaystyle \large{5n-3}

When n = 5, substitute/change n to 5:—

\displaystyle \large{5(5)-3}

Evaluate:—

\displaystyle \large{25-3=\boxed{22}}

__________________________________________________________

<u>Summary</u>

  <u>Substitution</u>

Changing or replacing from a term to another terms/expression is called substitution.

Examples:—

If we are given the expression \displaystyle \large{2y-1} and we want to find the value when y = 4, simply replace y-term to 4.

\displaystyle \large{2(4)-1=8-1=\boxed{7}}
