To find the mean, u add up all the numbers and divide by how many numbers there are.
the mean : (4 + 8 + 5 + 7 + 6) / 5 = 30/5 = 6
for the median (the middle number)...first, put ur numbers in order...doing this is very important
4,5,(6),7,8.....the median (middle number) = 6
so both ur mean and ur median are 6 <==
Answer:
(3/7)^7
Step-by-step explanation:
When multiplying exponents we can use the formula: a^m x a^n = a^m+n.
In this case, we can plug in 3/7 for a, and their respective exponents as m and n.
(3/7)^3 x (3/7)^4= (3/7)^3+4= (3/7)^7
Hope this helps!

Answer:
x = 1 / 3
x = -1.5
Step-by-step explanation:
First move everything onto one side.
6x^2 + 7x - 3 = 0
Divide by 6:
x^2 + 7/6x - 0.5 = 0
Now, you can move the 0.5 to the other side because it is determined that this is not factorable.
x^2 + 7/6x = 0.5
Now you have to complete the square.
Take 1 / 2 of 7 / 6 and square it.
49 / 144
x^2 + 7/6x + 49/144 = 0.5 + 49/144
(x + 7 / 12)^2 = 121 / 144
Square root:
x + 7 / 12 = ±11 / 12
x = 1 / 3, x = -1.5
Answer:
y=250x-4
Step-by-step explanation:
If y represents the amount of money made in a week, y=250.
If x represents the amount of cakes that are made, x=?
You make $250(y) a week, you then spend $4(x) per cake, this would make the equation:
y=250x-4
Answer:
(1/4, ln(1/2))
Step-by-step explanation:
The slope of the given line is -1/4, so the perpendicular line will have a slope of -1/(-1/4) = 4.
The slope of the given function is its derivative:
y' = 2/(2x) = 1/x
That will have a value of 4 when x = 1/4.
The point on the graph where the slope is 4 is (x, y) = (1/4, ln(1/2)).
