Plz a book store owner randomly samples 100 customers on two separate days to see what their favorite type of book is. the data shows the results of the two samples.
mystery sports history total =100
day 1 38 27 35
day 2 42 24 34 100

the book store owner expects 850 customers.
based on the samples, about how many mystery books will the book store sell?
enter your answer rounded to the nearest whole number in the box.

340

Step-by-step explanation:

There are a total of 100+100 = 200 people surveyed over the 2 days.

There were 38+42 = 80 people who prefer mysteries.  This means 80/200 prefer mysteries.

This tells us that out of 850 customers,

80/200(850) = 68000/200 = 340 will probably purchase mystery books.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?
