Muffins 61 20 32 58 62 61 56
Bagels 34 45 43 42 46 72 75
A bakery recorded the number of muffins and bagels it sold for a seven day period. For the data presented, what does the value of 51 summarize?
A) mean of bagels
Eliminate
B) mean of muffins
C) range of bagels
D) range of muffins

mean (baggel) = 51

Mean (muffin) = 50

Range ( baggel) = 41

Range (muffin) = 42

Step-by-step explanation:

Mean is calculated by the total sum of values in the data set/ number of values in the data set.

a) Mean of Bagels= 34 +45+ 43+ 42 +46 +72 +75 / 7

=357/7 = 51

b) Mean of Muffins = 61 +20 +32 +58 +62 +61 +56 / 7

= 350/7 = 50

Range is calculated by highest value - lowest value in a data set.

For baggel data set, highest value is 75 while lowest value is 34

Range (baggel) = 75 - 34 = 41

For muffin data set, the highest value is 62, while the lowest is 20

Range (muffin) = 62 - 20 = 42

I hope this helps.

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
