A machinist worked 40 regular hours and 10 overtime hours during one week and earned
$660. If his regular pay Is $480, what did he earn during overtime hours?

$18 an hour

Step-by-step explanation:

The machinist made an extra ($660-$480 =) $180 working overtime. Since he worked 10 hours of overtime, it comes out to ($180/10 =) $18 an hour.

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
