The equation yˆ=105.416x+1249.309 models the amount of money, in dollars, a charity raises during an annual event when x people attend the charity dinner.

what does the y-intercept of the equation represent in context of the situation?

it costs the charity $105 to host the dinner.
if no one came to the dinner, the charity would still raise about $105.
it costs the charity $1250 to host the dinner.
if no one came to the dinner, the charity would still raise about $1250

  If no one came to the dinner, the charity would still raise about $1250

Step-by-step explanation:

The variable x represents the number of people who attend the charity dinner. When x=0, no people came to the dinner.

The variable y represents the amount of money raised (in dollars). When x=0, the value of y is about 1250. That is, the charity raises about $1250 when no people came to the dinner.

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.  

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
