<h2>Answer:</h2>

The theoretical probability of choosing a letter other than Z is 96.2%

<h2>Step-by-step explanation:</h2>

We know that there are 26 alphabets.

Also, the number of  alphabets which are other than Z are: 25

Now we are asked to find the theoretical probability of randomly choosing any letter except Z :

It is the ratio of the number of alphabets other than Z to the total number of alphabets.

which is calculated as:

Theoretical\ Probability=\dfrac{25}{26}\\\\\\Theoretical\ Probability=0.961538

In percent to the nearest tenth the theoretical probability is given by:

                    96.2%

Probability=(number of specific outcomes)/(total number of possible outcomes)

P(!Z)=25/26  as a fraction exact

P(!Z)≈96.2%  (approximation to nearest tenth of a percent)

 A contractor purchases 6 dozen pairs of padded work gloves for ​$87.12. She incorrectly calculates the unit price as ​$14.52 pe
artcher [175]

So, there are 6 dozen pairs of gloves. That amount of gloves costed $87.12. She calculated the amount per pair as 14.52. This was incorrect because she forgot about the majority of the 6 dozen(one dozen is the number 12). So that means there are not 6 pairs of gloves, in fact, there are 72 pairs of gloves. So, now that we have that number, we can <u>correctly</u> calculate the amount of gloves per pair. Now we have 2 answers. The amount per glove and the amount per pair

Answer 1: Each pair of gloves costs $1.21.

Answer 2: Each individual glove costs 61¢<em>(if there is a number under the hundredths place in the price, like in the thousandths, you </em><em>always</em><em> round upwards, in this case, the cost was .605, but you round up, making it 61¢)</em>

It takes 40 minutes for 8 people to paint 4 walls. how many minutes does it take 10 people to paint 7 walls?
timurjin [86]
Its not 70 its 56, because you have to see how many minutes it takes for 1 to do 4 walls which would be 40*8.
Then you have to see if how many minutes its take a person to do one wall which is 8*40/4 from getting the amount of the 1 person doing 4 walls and get 80.
Then you need to see how many walls a person can paint 7 walls out of 10 people.So, we know how many minutes for each wall which is 80 and then multiply it by 7 to get 560 and divide it by 10 to get a product of 56.

A shopkeeper sold 12 bags on the first day. The number became four times
dybincka [34]

The total number of the bags sold by the shopkeeper will be 65532.

<h3>What is number series?</h3>

The sequence formed by using the numbers is termed as the number series.So in this question from day one to day seven each day the sold items are multiplied by 4.

So the mathematical expression will be given as:

=(12\times 4^0)+(12\times 4^1)+(12\times 4^2)+(12\times 4^3)+(12\times 4^4)+(12\times 4^5)+(12\times 4^6)

=12+48+192+768+3072+12288+49152\\\\=65532

Hence the total number of the bags sold by the shopkeeper will be 65532.
