The correct answer is D. The number of concert tickets purchased and the number of concert tickets still available for purchase

Explanation:

In mathematics, a negative correlation occurs when the increase in one of the variables makes the other variable decrease or vice-versa. For example, there is a negative correlation between the amount of time an individual exercises and his/her weight because the more hours it is expected the individual weights less. Additionally, in a scatterplot (graphic that uses dots to represent variables) a negative correlation is represented as a downward line considering values start high on the y or vertical axis but slowly go down.

From the options given, the variables that would lead to a scatterplot with a negative correlations are "he number of concert tickets purchased and the number of concert tickets still available for purchase" because the more tickets purchased the fewer tickets available and vice-versa, which means if one variable increases the other falls and thus, they have a negative correlation.

Reuben bought 5CDS that were each the same priceIncluding sales tax, he paid a total of \$81.50. Each CD had a tax of $0.60. wha
Liula [17]

Answer:

The price of each CD before tax is $15.70

Step-by-step explanation:

Given that:

Number of CDs bought by Reuben = 5

Cost of five CDs = $81.50

Sales tax on each CD = $0.60

Sales tax on 5 CDs = 0.60*5 = $3.00

Price of CDs without tax = 81.50 - 3.00 = $78.50

Price of each CD = \frac{Cost\ of\ CDs}{No.\ of\ CDs}

Price of each CD = \frac{78.50}{5}

Price of each CD = $15.70

Hence,

The price of each CD before sales tax is $15.70

What is the solution of \sqrt(2x+4)=16? <br> x = 6 <br> x = 72 <br> x = 126 <br> no solution
Genrish500 [490]
√(2x+4)=16  square both sides

2x+4=256  subtract 4 from both sides

2x=252  divide both sides by 2

x=126

Step-by-step explanation:

The vertex is the maximum or minimum point of a quadratic, which we can see on the graph is (2,-2).

The axis of symmetry is the line about which the graph of the parabola is symmetric, which is the line x=2.
