If they flash at 30 and 40 seconds, then a diagram showing their timing helps

30, 60, 90, 120
40, 80, 120

So after 120 seconds, both lighthouses flash at the same time
120 sec = 2 minutes

So the answer is 10:42

tekilochka [14]

Answer: There are 26000 miles that will both be due at the same time.

Step-by-step explanation:

Since we have given that

Number of miles required by new vintage = 400

Number of miles if these services have must been performed by the dealer = 13000

We need to find the number of miles from now that will both be due at the same time.

We would use "LCM of 400 and 13000":

As we know that LCM of 400 and 13000 is 26000.

So, there are 26000 miles that will both be due at the same time.

14 POINTS PLEASE HELP WILL MARK BRAINLIEST NEED URGENTLY

Using correlation coefficients, it is found that a coefficient of -1 represents a strong negative correlation.

<h3>What is a correlation coefficient?</h3>

  • It is an index that measures correlation between two variables, assuming values between -1 and 1.
  • If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
  • If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.

For this problem, we have a correlation coefficient of -1, hence it means that:

  • The relation is negative, as -1 is a negative number.
  • The relation is strong, as the absolute value of the coefficient is of 1, which is greater than 0.6.
