Part a at the toaster company, the weekly cost to run the factory is $1400 and the cost of producing each toaster is an additional $4 per toaster. choose a function rule representing the weekly cost in dollars, f(x), of producing x toasters. a f(x)=1400x+4 b f(x)=4x+1400 c f(x)=4x−1400 d f(x)=1400−4x

B

Step-by-step explanation:

The cost of running the factory is £1400 meaning that you need to add the cost of the toasters on. Since the number of toasters produced is unknown we use x to represent that cost

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:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
