Answer:
Option b
Step-by-step explanation:
Given that a researcher measures IQ and weight for a group of college students.
In general, we think that the weight has nothing to do with IQ of a person and hence not correlated.
But if we go deep, we find that after a certain weight, the person becomes lazy and inactive with a chance to have reduced IQ
Weight gain causes also health problems including less activity of both brain and body and hence there is a chance for less IQ
So we find that as weight increases iq decreases and when weight decreases, IQ increases.
Thus we can say that there is a negative correlation but not necessarily near to one.
Hence option b is right
She read thirty four hundredths as three hundred four thousandths
72 minutes
We require their hourly rate of work
Maria cleans 
the house in 1 hour
Sasha cleans 
of the house in 1 hour
let x be the time it takes both to clean the house
+ = 
multiply through by 6x
3x + 2x = 6
5x = 6 ⇒ x = 
Together they can clean the house in 72 minutes
Answer:
The second option.
3x + 6 = 21.
Step-by-step explanation:
3x + 6 = 21.
If x = 5, plug it in.
3 · 5 + 6 = 21
15 + 6 = 21
