Answer:

Union and Intersection

Step-by-step explanation:

We know that the algebra of sets define the properties and laws of the sets.

The basic operations of sets are,

Union, Intersection, Complement of a set and Equality of sets.

Since, the operations addition, subtraction, multiplication and division are the basic arithmetic operations of numbers.

i.e. they are not in the algebra of sets.

So, we get that out of the given options, the operations in algebra of sets are Union and Intersection.

1. Alex bought 2 buckets of baseballs that cost $19.49 each, a bat that cost $125.50, and 2 pair of baseball socks that totaled
Blizzard [7]

Answer:

$90.02

Step-by-step explanation:

<u>Solve</u>

Formula: Change money = paid money – bill. Paid money = change + bill.

Given: <em>2</em> buckets of baseballs that cost $<em>19.49</em> each

A bat that cost $<em>125.50</em>, and <em>2</em> pairs of baseball socks that totaled $<em>29.50</em>

Tax on Alex's purchases equaled $<em>16</em>.

Paid with three $<em>100</em> bills.

To find: How much change Alex received if he paid with three $100 bills

Total payment + Total Tax  -Total cost

19.49 + 125.50 + 29.50  = 174.49 (Don't add the $16 tax because that will be taken from the amount we pay)

∴, <em>three </em>100 bills is 300

So, 300 - 174.49 = 109.51

109.51 - 16 = 90.51

90.51 - 0.49 = $90.02

An airline company claims in a recent advertisement that more than 94% of passenger luggage that is lost is recovered and reunit
Genrish500 [490]

Answer:

The null hypothesis is  H_o :  p  \le  0.94

The alternative hypothesis is   H_a :  p  >  0.94

Step-by-step explanation:

From the question we are told that

  The sample size is n =  315

   The population proportion is  p =  0.94

   The number of luggage that was recovered and reunited with the passenger in one day is  k =  276

   Generally the sample proportion is  mathematically represented as

       \r p = \frac{k}{n}

=>      \r p = \frac{276}{315}

=>      \r p = 0.876  

The null hypothesis is  H_o :  p  \le  0.94

The alternative hypothesis is   H_a :  p  >  0.94
