Answer:

49.5 texts

Step-by-step explanation:

The total number of students is

11+21+33+23+12 = 100

The middle is 50

150 is in the middle group

The median will be between 40 -59

The best estimate for the median is to add the 40+59 and divide by 2

(40+59)/2 = 99/2 = 49.5 texts

Listed below are the top 10 annual salaries (in millions of dollars) of TV personalities. Find the mean, median, mode, and midra
Svetlanka [38]

Answer:

a. 20.23

b. 14.1

c. 8.3, 9.2, 9.8, 12.1, 13.5, 14.7, 26.5, 34.7, 36.5, 37

d. 22.65

Step-by-step explanation:

Sum = 202.3

Count = 10

Mean = 202.3 / 10

Mean = 20.23

Since there is an even number of data values the median is the mean of the two data values in the middle, calculated as follows;

8.3, 9.2, 9.8, 12.1, 13.5, 14.7, 26.5, 34.7, 36.5, 37

Median = (13.5 + 14.7) / 2

Median = 14.1

Mode is the value or values in the data set that occur most frequently. Since all are occurred once so all the values will be considered as Mode;

Mode = 8.3, 9.2, 9.8, 12.1, 13.5, 14.7, 26.5, 34.7, 36.5, 37

Midrange = (Highest Value + Lowest Value) / 2

Midrange = (37 + 8.3) / 2

Midrange = 22.65

for the equation x over 3 equals 15 the student found the value of x to be 5 explain the error what is the correct answer
otez555 [7]
If you divide 5 over 3 you get the decimal 1.6, not 15.
the correct answer would be 45. 
how do i get that? read below.
________________________________
to solve:
\frac{x}{3} = 15
1.multiply each side by 3, to get the 3 on the left side to cancel out. so you get x = 15 times 3.
2. 15 * 3 = 45

AlekseyPX
The fractions ordered from least to greatest are 7/10, 5/6, and 11/12. This is because 5/6 = 11/12 and 7/10 equals closer to 2/3.
