En la cocina Julio, el cocinero, repartió todas las magdalenas que horneó de la siguiente forma: entregó 10 magdalenas a cada grupo de alumnos y sobraron 4 magdalenas. Sin embargo, si se hubiera repartido 14 magdalenas a cada grupo de alumnos habrían faltado 12 magdalenas. ¿Cuántos grupos de alumnos hay y cuántas magdalenas en total horneó Julio?

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

angle efh= angle egh

look at the picture i have filled out a table for it. hope this .
