Alocal pizzeria sold 72 pizza's yesterday. the owner offers the emplyees a bonus if the number of pizza's sold increases by 30% today. how many total pizza's must the pizzeria sell for emplyees to recieve the bonus?

65 + 0.20(65) = 65 + 13 = 78..they would have to sell 78 to get the bonus

(65 - 60) / 65 = 5/65 = 0.0769 x 100 = 7.69 rounds to 7.7 % decrease compared to the 65 pizza's sold yesterday

Step-by-step explanation:

They have to sell a total of 94 pizzas.

Step-by-step explanation:

%30/%100 = x/72         Cross multiply this to get 2160=100x.

Divide 2160 by 100 to get 21.6. The pizza place has to sell 22 more pizzas today (as you can't sell a 6th of a pizza) which is equivalent to 94 pizzas.

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.

77
