There are no given choices so I can't exactly answer this question. However, I can tell you the form of the probable answer to the choices that you have. When two variables have a direct relationship, the general formula would be: y = kx, where k is a constant. In this problem, the independent variable is number of hours, say t, so x= t. Consequently, y = earnings, say E. So, the answer would probably have the form of: E = kt, where k could be any real number.

PLEASE HELP!!! 100 PTS +Brainliest!!!Given the following values, which point would be considered an outlier?

True [87]

Answer:

Option C, (6, 8.4)

Step-by-step explanation:

It would be option C because all of the other ones, both the y and x value is almost the same. (2, 2.1) (4, 3.8) and (9, 9) are all really close in y and x values. While (6, 8.4) has a y value that is over 2 more than x.

Michael drove his car for 150 minutes at a constant speed of 75 miles per hour and then for another 2 hours at a constant speed

swat32

Answer:

he traveled a total of 349.5 miles.

Step-by-step explanation:

*First we convert the 150 minutes to hours, that is :

$h=\frac{1.150}{60} \\h=2.5$

Now we determine the distance Michael traversed during those 2.5 hours:

$d_{1} =2.5.75 \\d_{1} =187.5\\$

He transversed 187.5 miles.

We also determine the distance he tranversed the two remaining hours:

$d_{2} =2.81 \\d_{2} =162$

He also traveled 162 miles

Finally we add both traversed distances:

$d_{t}=187.5+162 \\d_{t} =349.5\\$

So , he traveled a total of 349.5 miles.

A train leaves Little Rock, Arkansas, and travels north at 70 kilometers per hour. Another train leaves at the same time and tr

Ipatiy [6.2K]

Train A speed= 70 km/h north
Train B speed= 75 km/h south
Opposite directions= add speeds 70+75=145
Distance= 435 Km
Time= d/s; 435/145= 3 hours
It would take 3 hours for the trains to be 435 kilometers apart
