First, lets start with the greatest 4-digit number. That would be 9,999.99999999999, with 9 to ∞, because the next number is a 5-digit number. The smallest 6-digit number is 100,000, because the number preceding 100,000 is a 4 digit number. To find difference, you have to subtract. 100,000 minus 9,999.9999 continued gives you 90,000.000000 to ∞ with a one with 1 at the end. You would write 90,000.01 with bar notation over only the 0 to indicate that it goes on to infinity.
Let's translate each sentence into "Math".
Pineapple = p
Orange = x
is means equal
Pineapple is 7 times as heavy as an orange: p = 7x
Pineapple weighs 870 grams more than orange. p = 870 + x
Substitute p = 7x into the second equation:
7x = 870 + x
Subtract x from both sides
6x = 870
divide by 6
x = 145
The orange weighs 145 grams.
The pineapple weights 7 times the orange = 7(145) = 1015 grams.
Answer: Correlation without causation.
Correlation with causation: the number of high school seniors and high school graduates
Step-by-step explanation:
Correlation is a term that tells there is a relationship between two quantities.
Causation is a relationship where one quantity is affected by the other.
The number of graduates completely depends on the number of high school seniors.
So, the relationship between the number of high school seniors and high school graduates is a causation.
There is no relation between the amount of snowfall and the number of voters.
The number of nurses depends on the number of doctors but not completely.
It may be possible that the number of nurses will not increase with an increase in the number of doctors in a particular hospital.
So, there is a correlation without causation between the number of doctors and the number of nurses.
