Acompany had 80 employees whose salaries are summarized in the frequency distribution below. find the standard deviation. a frequency distribution has two columns labeled from left to right "salary (dollars)" and "employees". the entry pairs in each row are given as follows, where the salary is listed first and the number of employees is listed second: 5001 to 10,000, 19; 10,001 to 15,000, 14; 15,001 to 20,000, 12; 20,001 to 25,000, 16; 25,001 to 30,000, 19.

SD = 7588.09

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
