Answer:
76 degrees
Step-by-step explanation:
The total of the three angles in a triangle should equal 180 degrees. So to find the third angle, subtract the two given angles from 180
180 - 87 = 93
93 - 17 = 76
The third angle is 76 degrees because then all angles will add up to 180
Answer:
The answer is letter B, The water level in a bathtub as it drains over time.
Step-by-step explanation:
It is best to learn the meaning of <u>"negative correlation"</u> first.
Correlation- In Mathematics, "correlation" means a measure of the relationship between two variables.
<em>Positive Correlation- </em>when the values of the variables increase together.
<em>Negative Correlation- </em>when one value of a variable increases while the other variable's value decreases.
*The situation above is asking for a negative correlation, therefore the answer is letter B (The water level in a bathtub as it drains over time).
The variables are: <u>water level and draining time</u>
As the draining time increases, the water level in the bathtub decreases. This is clearly an example of a negative correlation.
