Answer:

C) Negative

Step-by-step explanation:

<u>Explanation</u>:-

<u>Correlation</u>:-

Correlation is a statistical measure that indicates the extent to which two or more variables fluctuate together

<u>Positive correlation :-</u>

Positive correlation occurs when the two variables of a function move in opposite directions. As the value of 'x' increases ,the Value of 'y' increases. Like wise the value of 'y' decreases, the value of 'x' decreases.

<u>Negative correlation:-</u>

Negative correlation occurs when the two variables of a function move in opposite directions. As the value of 'x' increases ,the Value of 'y' decreases. Like wise the value of 'y' decreases, the value of 'x' increases.

<u>Final answer</u>:-

If the linear correlation between two variables is negative then the slope of the regression line is also positive.

El área del gimnasio sería 2000 metros cuadrados

Step-by-step explanation:

Un lado del gimnasio será igual al lado de la cancha y el otro lado será igual al lado de la piscina.

Dado que tanto la cancha como la piscina tienen forma cuadrada. El lado de la cancha será raíz cuadrada de 2.500 m2 y el de la piscina será raíz cuadrada de 1.600 m2

Por lo tanto, el lado del gimnasio sería 50 y 40.

El área del gimnasio sería 50 * 40 = 2000 metros cuadrados

Find the solution<br> x/5 - 1/5 = x/3 + 1/4
Vilka [71]

Answer:

x = - 27/8

x=-3\frac{3}{8}

Step-by-step explanation:

¹²⁾x/5 - ¹²⁾1/5 = ²⁰⁾x/3 + ¹⁵⁾1/4

12x - 12 = 20x + 15

- 12 - 15 = 20x - 12x

- 27 = 8x

x = - 27/8

x=-3\frac{3}{8}

Troy sold 28 bags of popcorn and 40 candy bars and made $282. Jake sold 17 bags of popcorn and 20 bags of candy and made $160.50
Ghella [55]
One bag of popcorn would cost $6.50

To solve this, we can set up equations:
28p+40c=$282
17p+20c=$160.50

To solve this system, we would need to make either the candy bars the same or the bags of popcorn the same. Since we are solving for bags of popcorn, we will make the candy bars the same:
20(28p+40c=$282)
40(17p+20c=$160.50)

Which would give you:
560p+800c=$5,640
680p+800c=$6,420

Subtract them:
 (680p+800c=$6,420)
-(560p+800c=$5,640)
_________________
120p=$780

Now divide by 120 to get the price of one bag of popcorn:
120p=$780
_________
       120

p=$6.50
