Answer:

B. Long weekends and highway traffic on Friday afternoon

Step-by-step explanation:

Correlation is used to measure the strength of the relationship among variables. The variables are said to be strongly correlated if their relationship is strong.

Here, In option (A) Company's quarterly earnings reports and Stock performance has usually little correlation between them. So, this option is not true.

On long weekends people usually go for a family trip or their own home so it results in more highway traffic on Friday afternoon. Hence, there is a strong correlation between Long weekends and highway traffic.

As the price of beef and dairy product does not depend on each other. So, it doesn't have a strong correlation.

Similarly, Option (D) is also not true.

Answer:

Step-by-step explanation:

Let's look at the first two, and hopefully you'll be able to figure the rest out:

1. Answer below

$d = rt$

The problem asks us to solve for $r$ , so that means we need to get $r$ on one side of the equation by itself. To do so, we will need to divide both sides of the equation by $t$ :

$\frac{d}{t} = \frac{rt}{t}$

$\frac{d}{t} = r$

2. Answer below

$B = T - Lc$

The problem asks us to solve for $T$ , so that means we need to get $T$ on one side of the equation by itself. To do so, we will need to add $Lc$ to both sides of equation:

$B + Lc = T - Lc + Lc$

$B + Lc = T$

Answer:

61.7295 (61.7) miles

If I'm reading this correctly, this is just a simple addition equation. You'd add up 23.4865 and 38.243 to get 61.7295 miles, or 61.7 miles.

Hope I helped! ☺
