Answer:
Mean- 14.5
Median- 15.5
Interquartile Range- 7.5
Step-by-step explanation:
The mean is a type of average. It is the sum (total) of all the values in a set of data.
The median is the middle number in a sorted, ascending or descending, list of numbers.
The interquartile range describes the middle 50% of values when ordered from lowest to highest.
STEP 1:
convert gallons to cups & calculate total number of cups
1 gallon= 16 cups
= 8 gallons * 16 cups/gallon
= 128 cups total
STEP 2:
calculate total cups estimated for 20 guests
= 20 guests * 2 cups/guest
= 40 cups needed for guests
STEP 3:
subtract the difference between step 1 and step 2 to find leftover punch
= 128 cups - 40 cups
= 88 cups leftover
OR
GALLONS LEFTOVER
= 88 ÷ 16 cups/gallon= 5 1/2 gallons
ANSWER: There will be 88 cups or 5 1/2 gallons of punch leftover.
Hope this helps! :)
Answer:
Since the question is indicating to use a graphing calculator, we can assume that we would be required to graph both of the equations.
Red = 
Blue = 
By graphing those equations, we can determine the solution(s)
The points where the graphs intersect would be your coordinates to derive your solution
Red = (1.864, 1.966)
Blue = (-0.427, 1.254)
The solutions would be the x-value of the ordered pair, in this case,
x = 1.864 AND x = -0.427
My answer is 28.5 i believe i just added all of my numbers for the x variable and i divided it by by 6 because thats how many numbers you have
Answer:
= 21x - 1
Step-by-step explanation:
= (4x + 12x) + (5x - 1)
= 4x + 12x + 5x - 1
= 16x + 5x - 1
= 21x - 1
