which of these is not a random sample that would be valid to determine the favorite food of students in your school?

a. five students at a local pizza parlor
b. Every sixth student on the attendance list
c. every tenth student entering school in the morning
d. three students from each lunch table in the lunchroom

explain your

D. three students from each lunch table in the lunchroom.

Step-by-step explanation:

I supposed that was the only option that made sense.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
