Answer:
Since, mean of 200 items was 50 and number of items =200
So, mean =50
Also, we know mean = number of itemssum of items
∴50=200sum of items
Sum of items = 200×50=10000
Later on, it was discovered that the two items were misread as 92 and 8 instead of 192 and 88 respectively
Then misread instead Correct item
92 192 192-92=100
8 88 88-8=80
∴ Correct sum of items =10000+180=10180
∴ Correct mean = number of items/sum of items
=10180/200 =50.9
Answer:
The number of calories are directly proportional to the number of ounces.
Step-by-step explanation:
We can relate these values as:
Let x be the calories in 4 ounces of broiled hamburger.
=>
=>
Dividing by 3 on both sides;
x = 327 approx
We can see that 4 ounces contain 327 calories.
Per ounce will have calories.
As the quantity of hamburger increases, the calories count also increases.
