Determine the mean
The mean (M) of a data is calculated as thus:
Where
n = number of data.
In this case,
n = 5
and
= sum of data
So, the formula becomes
<em>Hence, the mean is 77</em>
Answer:
Step-by-step explanation:
12 x 3=36 yx
12x2x3= 72 x*y
She boils 500 L of water and makes 80 grams, we are being asked to covert and solve for how many grams of pasta she will make if she boils 2500 mL.
The first think we need to do is convert 2500 mL to how many Liters.
2500 mL = ? how many liters.
2500 ml = 2.5 liters
Now, we need to set up a proportion to see how many grams we can make if we boiled 2.5 liters of water.
Set up a proportion.
500/80 = 2.5/x
First, we cross multiply.
500*x = 80*2.5
500x = 200
Now, divide each side by 500 to solve for x.
500x/500 = 200/500
x= 0.4
Final answer: Margo can make 0.4 grams of pasta if he boils 2500 mL of water.
0.78 as a fraction is - 39/50
