Answer:
Mean= 31
Step-by-step explanation:
To find the mean you need to add all the number together and then divide by how many ever numbers there are.
In this case
25 + 25 + 30 + 35 + 40=155
There are 5 numbers so you would divide by 5
155/5
=31
Answer:
the answer is number 1
Step-by-step explanation:
integers are whole numbers
Answer:
The equation of required line is: 
Step-by-step explanation:
We need to write equation in the form Ax+By+C=0 of the line parallel to 
and through the point (-2,3)
First we need to find slope and y-intercept of the required line.
Using equation of line to find slope.
Since the given line and required lines are parallel there slope is same.
Writing equation in slope intercept form: 
where m is slope.
So, the slope m = 5/8
The slope of required line is 
Now finding y-intercept using slope and point(-2,3)
So, the equation of required line having slope and y-intercept 
So, The equation of required line is:
Answer:
1 7/12 = 1.58
Step-by-step explanation:
If you divide 7 by 12, you will get 0.583... If you add 1 in the ones, that'll be
1.583... or 1.58.
When the ball reaches the ground is equal to one of the zeros, or x-intercepts. In order to find the zeros of a function, you need to factor the equation.
y=16x^2+64x
y=-16x(x-4)
The zeros are x=0 and x=4
Therefore the answer is D, after 4 seconds.
Hope this helps!
