Answer:

The chi-square null hypothesis for the study that "socioeconomic status is related to smoking behavior" is False

Step-by-step explanation:

The chi-square null hypothesis is false because the chi-square null hypothesis states that no relationship exists on the categorical variables in a population, they are all independent of each other.

A board 1.2 m long is cut into two so that the length of the longer piece is 15cm longer than twice the length of the shortest p
MAXImum [283]

Answer:

The length of the shorter piece=0.35 m

Step-by-step explanation:

Let the lengths be as follow;

Shorter piece=x

Longer piece=15 cm longer than twice shorter piece(x)

Since 1 m=100 cm, 15 cm=15/100=0.15 m

Longer piece= (2×x)+0.15=2x+0.15

Total length=1.2 m

Total length=shorter piece+longer piece

Replacing;

1.2=x+2x+0.15

3x=1.2-0.15

3x=1.05

x=(1.05/3)=0.35

The length of the shorter piece=x=0.35

Jobisdone [24]

Answer:

1. 2w+2*(5w) less than or equal to 96

Step-by-step explan2ation:

The width here is in fact 8, so it is possible to get 96, but it has to be either 96 or lower, so in theory 3 is the only one with the correct symbols. Also, 2w represents the fact that the width, w, is multiplied by 2 since its perimeter. 5x represents length, so length also needs to be multiplied twice. Sorry I don't have time to answer the rest
