Answer:
the answer is -0.5.
Step-by-step explanation: First subtract 17 from 15 to know what u need to get. Know that u get -2, we have to figure out what to do to get -2 out of 4. First to get positive 2, multiply by 0.5, than since we need to get negative 2, add a negative in front. Hence, the answer is -0.5 .
Answer:
1 hour 20 minutes
Step-by-step explanation:
Time to fix car ( repair time ) = 20 minutes
Breakdown rate ( λ ) = 2 car per hour
<u>first step : determine service the service rate ( μ )</u>
= 60 minutes / 20 minutes
= 3 cars per hour
<u>next : determine the average waiting time for a disabled car </u>
= 1 / (μ - λ)
= 1 / service rate - breakdown rate
= 1 / ( 3 - 2 )
= 1 / 1 = 1 hour
Finally Total time for a disabled car to be fixed
= repair time + average waiting time
= 20 minutes + 60 minutes
= 1 hour 20 minutes
Answer:
x=2
Step-by-step explanation:
For this case we first calculate the area of the complete rectangle.
We have then:
A1 = (8.5) * (11)
A1 = 93.5
Then, we calculate the area of each circle:
A2 = pi * r ^ 2
A2 = (3.14) * (2/2) ^ 2
A2 = 3.14
The total area is given by:
A = A1 - 4 * A2
A = 93.5 - 4 * (3.14)
A = 80.94 in ^ 2
Answer:
A) 80.94
The only true statement is A:
"The data show a negative linear relationship."
<h3>
</h3><h3>
Which statement is true?</h3>
On the graph, we can see how the car's vale decreases almost linearly with the age of the car.
Where the response variable would be the one on the y-axis, which is the car's value.
For that linear behavior, we know that there is a correlation coefficient different than zero. So options B, C, and D are false.
Finally, we already saw the linear behavior (decreasing, so the slope is negative). Then we conclude that the only true statement is A.
