Slope is -12 and y-intercept is 3
50 m/s is going to be 180 km/h or 3 km/s.
50 / 1000 = 0.05
0.05 x 60 = 3 kilometers a minute.
3 x 60 = 180 kilometers an hour.
50 m/s divided by 1 kilometer = 0.05 kilometers a second. You then multiply it by 60 to get it in minutes, and then 60 again to get it in hours. because their are 3600 seconds in an hour. So you could divide 50 meters per second by 1000 meters or 1 kilometer and then multiply it by 3600 seconds to get 180 kilometers an hour.
The price after the discount was $45.
When the sporting goods store bought the snowboard and marked it up by 25%, the price became:
<em>= Original cost x ( 1 + markup percentage)</em>
= 120 x ( 1 + 25%)
= 120 x 1.25
= $150
The snowboard was then discounted by 70%, the new price becomes:
<em>= Current price x ( 1 - discount rate)</em>
= 150 x ( 1 - 70%)
= 150 x 30%
= $45
In conclusion, the price after the discount was $45.

Answer:
Polynomial expression that represents the area of blanket:
If 
: 
Step-by-step explanation:
The area of the rectangle can be calculated with the formula:
Being l the lenght of the rectangle and w the width of the rectangle.
In this case, the lenght and the width are represented with:
Substitute them into :
Then:
Use Distributive property (Remember the Product of powers property: 
):
Add like terms:
(Simplied form)
Evaluate :
The population correlation coefficient is significant if the correlation is closer to 1, less significant is closer to zero, and not significant at all if the correlation coefficient is zero.
- Correlation coefficients are used in determining the significance of a population and the strength of the relationship <u>between two variables. </u>
- This relationship can either be strong, weak, or not exist.
- The correlation coefficient can have values between 0 and 1 inclusive. The population correlation coefficient is significant if the correlation is closer to 1, less significant is closer to zero, and not significant at all if the correlation coefficient is zero.
