Answer:
y= -x+5
Step-by-step explanation:
<em>The</em><em> </em><em>slop</em><em>e</em><em> </em><em>of</em><em> </em><em>th</em><em>e</em><em> </em><em>two</em><em> </em><em>paral</em><em>lel</em><em> </em><em>lin</em><em>es</em><em> </em><em>is</em><em> </em><em>equ</em><em>al</em>
<em>so</em><em>,</em><em> the</em><em> slope</em><em> of</em><em> </em>
<em>y</em><em>=</em><em>-x-3</em><em> </em><em>is</em><em> </em><em>-</em><em>1</em><em> </em>
<em>slo</em><em>pe</em><em>=</em><em>y2-y1</em><em>/</em><em>x2-x1</em><em>=</em><em>-</em><em>3</em><em>-</em><em>1</em><em>5</em><em>/</em><em>8</em><em>-</em><em>-</em><em>1</em><em>0</em><em>=</em><em>-</em><em>1</em>
<em>the</em><em> </em><em>equa</em><em>tion</em><em> </em><em>of</em><em> </em><em>t</em><em>he</em><em> </em><em>line</em><em> </em><em>i</em><em>s</em>
<em>y-15</em><em>=</em><em> </em><em>-</em><em>1</em><em>(</em><em>x--10</em><em>)</em>
<em>y</em><em>=</em><em> </em><em>-x-10</em><em>+</em><em>1</em><em>5</em>
<em>y</em><em>=</em><em> </em><em>-x</em><em>+</em><em>5</em>
A negative association means as one increases, the other decreases. For example x goes up 1 and y goes down 1.
Because set B and set D show positive correlation, they can automatically be deleted.
Set A shows a negative correlation, however the change between the x and y value are steady. As x increase one, y decreases one. So the line is straight meaning it is linear.
Leaving our answer to be C
We can check this by looking at the chart, the chart shows a negative correlation between the values, we can also check to see that it is not linear because it begins with x rising a and y decreasing two, however it then changes to f rising one and y decreasing 1. So the equation is non-linear
So your answer is
C. Set C
An outlier in math is a value on a graph that varies greatly from all the others, it is either way higher or way lower than the other values. This is shown by point D because it is far away from the rest of the data on the table.
So your answer is
D. Point D
As the temperature increases, the amount of jackets decreases. This shows a negative association. So because the temperature is increasing the number of jackets decreases, so answer choices A and C can be eliminated because they each say the number of coats will increase. And as previously stated, as the temperature increases the amount of jackets decreases, meaning the association is negative.
So your answer is
B. The number of coats in the coat check will decrease because the graph shows a negative association.
260 is the correct answer because 65 is twenty percent of 260
1st one is the 4th caller
2nd one is the 10th caller
I believe this is right! Hope it helps!
<em><u>Part B (Taxi):</u></em>
12 miles = 0.5 miles + (115×0.1) miles
Rate: $2.40 + (115×0.20)
= $25.40
Total cost (with tip): $25.40 + $2
= $27.40
20 miles = 0.5 miles + (195×0.1) miles
Rate: $2.40 + (195×0.20)
= $41.40
Total cost (with tip): $41.40 + $2
= $43.40
50 miles = 0.5 miles + (495×0.1) miles
Rate: $2.40 + (495×0.20)
= $101.40
Total cost (with tip): $101.40 + $2
= $103.40
<em><u>Part B (Uber):</u></em>
12 miles (rate) = $1 + ($1.05×12)
= $13.60
Total cost (with tip): $13.60 + $2
= $15.60
20 miles (rate) = $1 + ($1.05×20)
= $22
Total cost (with tip): $22 + $2
= $24
50 miles (rate) = $1 + ($1.05×50)
= $53.50
Total cost (with tip): $53.50 + $2
= $55.50
<em><u>Part C</u></em>
Uber is a better mode of transportation. This is because given the same distance travelled for both the taxi and the Uber, Uber has a lower cost compared to the taxi.
