Answer: 0.82 miles per gallon
Step-by-step explanation:
Given : Jenna has bought a new hybrid car. Each week for a period of seven weeks, she has noted the fuel efficiency (x) (in miles per gallon) of her car.
The results are :45 44 43 44 45 44 43
The formula to find the standard deviation is given by :-
First we find mean of the given data ,
Now,
Now, standard deviation of the above results will be :-
Hence, the standard deviation of these results = 0.82 miles per gallon
Answer:
51 degrees
Step-by-step explanation:
gave up on delta math
A= (-4,2)
The x value (-4) stays the same when reflected over the x-axis, so only the y-value gets reflected and therefore changed.
The resultant coordinate is (-4,2)

Step-by-step explanation:
Answer:
is the slope intercept form for 16x+9y=40
Step-by-step explanation:
Here, the given equation is 16 x + 9 y = 40
Now, the slope intercept form of an equation is y = mx + c,
here m = slope of the equation, b = y - intercept
So, now 16x + 9y = 40 on simplification gives
9y = 40 - 16x
or 
or, is the slope intercept form of the given equation.
Here, m = (-16/9) and y- intercept = 40/9
