Step-by-step explanation:
$50 corresponds to 4 kg
That means there must be a number that when you multiply by 4 you get 50.
Let that number be k. k is the price of cheese per kg.
1 kg: y = k * 1

Answer: 5h+4=A
Step-by-step explanation:
She gets five dollars an hour so for one hour she gets five dollars, for two hours she gets 2 times 5 dollars (10 dollars), for three hours she gets 3 times 5 dollars (15 dollars) etc...

Answer:
5
Step-by-step explanation:
The formula for Standard Error =
Standard deviation /√n
Where
n = Random number of samples
From the above question,
Standard deviation = 10
n = 4
Hence, Standard Error is calculated as:
= 10/√4
= 10/2
= 5
Therefore, the Standard error = 5
