Answer:

Step-by-step explanation:
We want to simplify:

We rewrite as:

We split the radical sign to obtain:

Simplify the square root for the perfect squares to get:

Therefore the simplified form is: 
Answer:
I believe the answer is- The mean and MAD can accurately describe the "typical" value in the symmetric data set.
Step-by-step explanation:
The other answers don't make sense because the mean and MAD are being used for symmetrical distributions and asymmetrical means uneven distributions.
Answer:
x = 1
Step-by-step explanation:
2x + 1 = -1
2x = -1 - 1
2x = -2
x = -2 ÷ -2
x = 1
The domain is {0≤x≤200}.
This is because the domain is x, the number of cakes. The smallest number of cakes she can bake is 0.
Since she is buying enough materials to make 200 cakes, this number is the largest number of cakes she can bake.
Answer:
4.9 units
Step-by-step explanation:
We are dealing with a Right angle triangle, and the c is actually the hypotenuse. We are given the measures of a and b.
a being 4, and b being 3.
We need to use the Pythagorean Theorem to solve this.

we can rewrite this as;

Calculation time
15 + 9 = c
c = 24
Now we find the square root of each equation to determine what
is.

4 + 3 = 4.89897948557
Let's round that to the nearest tenth.
4.9 units
Hope this helped :)
