Answer:
Mean travel time = 10.33 minutes
Step-by-step explanation:
The mean of a distribution is a measure of central tendency that shows the centre of a set of data. Mathematically, it is represented as:
Mean = Sum of the terms ÷ Number of terms
Mean = (10 + 13 + 16 + 5 + 4 + 14) ÷ 6
Mean = 62 ÷ 6 = 10.33
∴ Mean travel time = 10.33 minutes
N:B 10.33 minutes = 10 minutes + 0.33 minutes
converting 0.33 minutes to seconds
1 minute = 60 seconds
∴ 0.33 minute = 60 × 0.33 = 19.8 seconds
∴ Mean time = 10 minutes 20 seconds
Answer:
<em>B) x = 3</em>
Step-by-step explanation:
lets plug in the first option to see if it works
3x=9
3*27=9
<em>thats not right</em> ( 3*27 = 81 )
Next, we try the second option
3x=9
3*3=9
<em>that looks more like a resonable answer right?</em>
<em>now to check our work</em>
3+3+3=9
<em>Its correct!</em>
<em></em>
<em>Hope that helps</em>

Answer:
X-int: (2,0) , (-5,0)
Y-int: (0,-10)
Step-by-step explanation:
To solve for the x-int, set y to 0.
0= x^2 + 3x - 10
0= (x-2)(x+5)
x= 2, and -5
To solve for the y-int, set x to 0.
y= (0)^2 + 3(0) - 10
y= -10
