12. Answer: 2130
<u>Step-by-step explanation:</u>
T = -0.01y + 10.6
9.2 = -0.01y + 10.6
<u>-10.6</u> <u> -10.6 </u>
-1.4 = -0.01y
<u> ÷-0.01</u> <u>÷-0.01 </u>
140 = y
"y" represents the number of years after 1990
1990 + 140
= 2130

13. Answer: -0.0036° per foot
<u>Step-by-step explanation:</u>
Since the relationship is linear, then we can set up the values as x, y coordinates and use the slope formula to find the rate of degrees over feet.
(6562, 63) and (16405, 28)
rate =

Answer:
y-24=m(x--4)
Step-by-step explanation:
point slope form:
y-y₁=m(x-x₁)
1) find the slope or "m" first:
slope formula: (y2-y1)/(x2-x1)
(-53-24)/7+4
-77/11=-7
slope=-7
so
y-y₁=-7(x-x₁)
y1=24
x1=-4
y-24=m(x--4)
hope this helps!
Answer:
e) The number of minutes for a car to get from the intersection to the administration building
Step-by-step explanation:
Continuous Data:
Data that can take any value (an infinite number of values) within a certain range.
For example, the statistics of a group of people form continuous data, but the number of people in that group form discrete data.
Inglés
In this case, counting items such as cars, bicycles, people, are considered discrete data. They exclusively take integer values.
But time data can take continuous values.
