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 $E_{11}=12$

She needs 3/4 cup of water she needs 10 more servings what's the answer A 1/1/5 b 3/1/4 c 7/2/4 d 8/2/3

Eddi Din [679]

<h2><u>Corect option</u> :</h2>

$= \color{plum}\tt(C) 7 \frac{2}{4}$

<h2><u>Answer with steps</u> :</h2>

Quantity of water she needs $= \tt \frac{3}{4} \: cup$

Number of servings she needs = 10

Number of cups of water she will need :

$= \tt \frac{3}{4} \: \times 10$

$= \tt\frac{30}{4}$

$=\tt 7\frac{2}{4} \: cups$

Thus, she needs $\tt 7\frac{2}{4} \: cups$ of water.

Therefore, the correct option is $\color{plum}\tt(C) 7 \frac{2}{4}$
