3. At a local restaurant, the health inspector visits every 7 days, and the fire inspector visits every 12 days. (a) Make a tabl

Answer: The correct choice is (C) A = {1, 2, 3, 4, 5, 7, 8}.

Step-by-step explanation: We have eight identical slips of paper, each numbered from one to eight, which have been mixed inside a bag.

The sample space, S is as follows:

S = {1, 2, 3, 4, 5, 6, 7, 8}.

Subset A consists of the complement of the event where the number 6 is drawn.

Let 'B' denote the event of drawing the number 6.

Thus, B = {6}.

Since 'A' represents the complement of 'B', it will include all elements in the sample space 'S' that are not part of set 'B'.

Therefore,

A = B' = {1, 2, 3, 4, 5, 7, 8}

So, A = {1, 2, 3, 4, 5, 7, 8}.

Consequently, (C) is the correct choice.

An ANOVA test is the appropriate method. Step-by-step explanation: The ANOVA test, which assesses the means of more than two samples, will be applied here. Given that three different test groups were utilized, this statistical test will be necessary for determining if the means are the same. Note that this test merely informs us of the means' equality, not which mean surpasses the others; for that determination, three separate hypothesis tests would be required, comparing two means at a time.

Answer: You would need 40 bushels of seed to plant 30 acres of wheat.

Step-by-step explanation:

<pTypically, 1 1/3 bushels of seed are necessary to cultivate 1 acre of wheat. In improper fraction form, 1 1/3 bushels becomes 4/3 bushels.

Let x denote the bushels of seed required for 30 acres. Thus, we have

4/3 bushels = 1 acre

x = 30 acres

Cross multiplying gives us

x × 1 = 4/3 × 30

x = 40 bushels of seed

x2 – 6x + 9  is the answer

Responses

19 fiction books

7 nonfiction books

Explanation

x + y = 26............................................. (i)

x – y = 12............................................ (ii)

By adding the two equations, Elliot obtained the result of

2x = 38.

When divided by 2;

x = 19

Therefore, there are 19 fiction books.

Substituting x into equation (i),

x + y = 26            when x = 19

19 + y = 26

y = 26 - 19

   = 7

This means there are 7 nonfiction books
