Four friends ordered a pizza cut into eight slices. The whole pizza was eaten, with each friend eating a different number of sli
raketka [301]

Answer:

{0,1,3,4}

Step-by-step explanation:

Given, total no of slices=8.

Total no of friends=4.

also each friend didnt ate more than the other three.

let a,b,c,d be no of slices ate by the friends 1,2,3,4 respectively.

given sum of a+b+c+d=8.

now applying the second condition

a\leq b+c+d \\b\leq c+d+a\\c\leq a+b+d\\d\leq a+b+c

so each of a,b,c,d must be less than or equal to 4.

which means 5 values are possible{0,1,2,3,4}.from this set you have to select 4 values such that their sum is 8.hence, those values are {0,1,3,4}.

Each of 8 students reported the number of movies they saw in the past year. This is what they reported:
elena-14-01-66 [18.8K]

Answer:

10.75

11

Step-by-step explanation:

the mean is the average, so add up all of the values and divide by 8 because there are 8 values :

(11 + 17 + 14 + 11 + 4 + 7 + 11 + 11)/8 = 10.75

the median is the middle value when the numbers are written in ascending or descending order :

4, 7, 11, 11, 11, 11, 14, 17

we can cross out the values on the ends, to get to the middle. if we do this, we are left with 11, 11

find the average of these numbers :

which is 11.

An equilateral triangle has a perimeter of 48 centimeters. If the triangle is dilated by a factor of 0.75, what is the length of
elena55 [62]
The length of each side is 28 cm. 
the perimeter of the equilateral triangle is 48 cm. To find each side of the original triangle, you do 48/3=16cm. since the triangle dilate by 0.75, then you can just do 0.75*16=12cm. then you have to add 12 to 16 because the triangle gets bigger by 12 cm. so 16+12=28 cm.
