The sales of a certain brand of tv satisfy the linear model y = 110x + 5600 where y represents the number of sales in year x, with x = 0 corresponding to 1982, x = 1 corresponding to 1983, etc. how many units did they sell in 1987? the number of sales in 1987 was

6150 units were sold on 1987.

Step-by-step explanation:

Given equation that models the number of sales after x years since 1982,

y = 110x + 5600 -----(1)

∵ The number of years from 1982 to 1987 is 5,

Thus, for finding the number of sales on 1987,

We must put x = 5 in the equation (1),

Thus, the number of units sold on 1987,

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.  

use formula for the circle a=3.14
