Answer:
Below.
Step-by-step explanation:
10, 14, 13, 13, 16, 12, 9,7
Arrange in ascending order:
7 9 10 12 13 13 14 16
The median = the mean of the middle 2 values
= (12 + 13) / 2 = 12.5 hours.
The mean = (7 +9 +10 +12+ 13+ 13+ 14+ 16) / 8
= 94/8
= 11.8 hours to nearest tenth.
Answer:
Hello
No function.There are two 7's on the x-axis. There can be 2 or more same numbers on the y-axis.
Step-by-step explanation:
Answer is No.
Answer:
y= 5x+13
Step-by-step explanation:
<u>Slope- intercept form</u>
y= mx +b, where m is the gradient and b is the y-intercept.
Parallel lines have the same gradient.
y= 5x +4
Gradient of given line= 5
Thus, gradient of line= 5
Subst. m=5 into the equation.
y= 5x +b
To find the value of b, substitute a coordinate
When x= -2, y=3,
3= 5(-2) +b
3= -10 +b
b= 3 +10 <em>(</em><em>+</em><em>1</em><em>0</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
b= 13
Thus, the equation of the line is y= 5x +13.
I think it's 7 because 7 x 2 = 14
