1:9
Step-by-step explanation:
6×60=360min
40:360
1:9
The answer is 7 times 4 goes into 30.
<u>Step-by-step explanation</u>:
- To check how many times a number goes into a larger number, use division.
- Divide 30 by 4.
⇒ 4
7 = 28 and 30-28 = 2
⇒ The quotient is 7.
⇒ The remainder is 2.
So, the number 4 goes 7 times into 30.
Answer:

Step-by-step explanation:
<u>Answer-</u>
<em>A. strong negative correlation.</em>
<u>Solution-</u>
<u>Direction of a relationship</u>
- Positive- If one variable increases, the other tends to also increase. If one decreases, the other tends to also. It is represented by positive numbers(i.e 0 to 1).
-
Negative- If one variable increases, the other tends to decrease, and vice-versa. It is represented by negative numbers(i.e 0 to -1)
<u>Strength of a relationship</u>
- Perfect Relationship- When two variables are linearly related, the correlation coefficient is either 1 or -1. They are said to be perfectly linearly related, either positively or negatively.
- No relationship- When two variables have no relationship at all, their correlation is 0.
As in this case, correlation coefficient was found to be -0.91, which is negative and close to -1, so it is a strong negative correlation.
