Answer:

True

Step-by-step explanation:

This equation correctly represents the total cost of the food that the friends ended up paying for the popcorn and sodas. In this expression, the cost of each individual soda is represented by the variable x which is multiplied by 4 since each one of the four friend's purchased their own soda. After making this multiplication process that product is added to the initial $12 that they all spent together on the popcorn.

Can someone please help me? I put the question below!
pogonyaev

Answer:

<h2>V  =  360π in³</h2>

Step-by-step explanation:

the formula for the volume of a cone of base radius r and height h is:

V = (1/3)(πr²)(h).  Here, r = 6 in and h = 30 in.  Then,

V = (1/3)(π)(6 in)²(30 in), or

   = (1/3)π(36 in²)(30 in), or

V  =  360π in³

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.
