Amanager is considering three new machines for filling boxes of cereal at a processing plant. each of the three machines is assigned to 10 randomly selected employees. the time required to fill 25 boxes using the machine is recorded. how many treatments does this single-factor experiment have?
a. 3
b. 10
c. 1
d. 25

3

Step-by-step explanation:

Given that a manager is considering three new machines for filling boxes of cereal at a processing plant. Each of the three machines is assigned to 10 randomly selected employees

Here the treatments are the no of machines. i.e. three machines are three treatment.

After selecting treatments 25 boxes using each machine is recorded.

Hence this is a one factor anova with three factors namely three machines affecting the result

Hence no of treatments = 3

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
