So basically, you find the total time required to complete the item, by addition of time taken by task A, task B, and task C -

TASK A - 2 and a half minutes is 2 minutes 30 seconds, which is 2(60) + 30 seconds = 120 + 30 = 150 seconds.

TASK B - 3 minutes 10 seconds, which is 3(60) + 10 = 190 seconds

LAST TASK - 1 minute = 1(60) = 60 seconds

add them up --- 150 + 190 + 60 = 400 seconds

Divide by 60 --- 400/60 = 40/6 = 20/3 minutes.

Now, 1 item takes 20/3 minutes.

let 'x' number of items take 25 minutes.

Therefore, divide (25)/(20/3) = (25*3)/20 = 15/4 = 3.75

Answer from: Quest

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable r represents the radius of the circle, h represents the x-offset from the origin, and k represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at ( h , k ) .

center: ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center: ( 3 , 1 ).

radius: 4

Answer from: Quest

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data. the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center. with the histogram, we cannot find any of these.
