In the United States, there has historically been a strong relationship between smoking and education, with well-educated people
Paraphin [41]

Answer:

The proportion of former smokers with a university education is (A) 0.15

The proportion of men with a high school education that are current or former smokers is (B) 0.30

The degrees of freedom for the chi-square test for this two-way table are (B) 6

Step-by-step explanation:

The first thing to note is the two way table and ensure the proper arrangement of the figures in the table (Kindly find attached a picture of how the table should look)

Now, on to the first question on the former smokers with a university education = (43+28)/459 = 71/459 = 0.15 which is option A. [This is the total sum of former smokers with college and graduate school education].

The second question on the proportion of men with a high school education that are current or former smokers = (54+31+36)/459 = 0.285 = 0.30 (approximate value) which is option B.

The third question on the degrees of freedom for the chi-square test for this two-way table can be found with the formula DF = (r-1)(c-1) where,

DF = Degree of freedom ,

r = number of rows = 3

c = number of columns = 4 [<em>Kindly note that you have to exempt the row and columns with the totals</em>]

Therefore, DF = (3-1)(4-1) =2*3 = 6 which is option B.

A $52 game is on sale for 20%<br> off. if the sale tax id 6%, how much will the game cost?
laila [671]

Answer:

$44.10

Step-by-step explanation:

Equation: 52+(52•.20) that is the first part for your answer you should get 10.4 or $10.40. Then you would take 52-10.4=41.60 then keeping that number in mind you do 41.60• .06 and get, rounded, 2.50. Then you would add 41.60+2.50 and get $44.10 as your answer.

Have a nice day and stay safe, all love from jen <3

I cannot figure out the work for this problem.
Vedmedyk [2.9K]
Your answer should be -2
Use PEMDAS if confused!
Parentheses
Exponent
Multiplication
Division
Addition
Subtraction.
You would first calculate the number in between your parentheses which would give you -1. Then do -1 to the power of 4(-1^4) which still gives you -1 and then multiply it by 2 which should give you your answer -2. :)
Hope this helps.
