Explanation:

The equation is $3x=36$

Frida started to solve the equation by adding 3 to both sides.

Thus, the equation becomes,

$3x+3=39$

This will not solve the equation.

To solve the equation $3x=36$ , we need to divide both sides of the equation by 3.

Thus, the equation becomes,

$\frac{3x}{3} =\frac{36}{3}$

Dividing we get,

$x=12$

Hence, Frida cannot solve the equation by adding 3 to both sides of the equation. To solve the equation, Frida needs to divide both sides of the equation by 3.

Thus, to solve the equation $3x=36$ Frida needs to divide both sides of the equation by 3.

Suppose you are interested in selling your home and would like to clear a net value of $300,000. If you have agreed to pay your

QveST [7]

Answer:

<h2>I need to sell the home for the price of $317,460.</h2>

Step-by-step explanation:

I need to pay 5.5% of the total to the broker.

I also want to gain $300,000 as a profit. I need to sell the house in such a price, so that after giving the 5.5% to the broker, i also have $300,000.

I need to find the value of 100%, where (100 - 5.5) = 94.5% represents $300,000.

Hence, 100% = $\frac{300000}{94.5} \times 100 = 317460.3$ .

True or false the mean is less sensitive to extreme scores than the median and this makes it a better measure than the median fo

That would be FALSE.

The median is a robust statistic that can only move a little bit even given the largest outlier. A single outlier can affect the mean, the average, arbitrarily much.

Of the following sets, which represents a function? (1 point)

yKpoI14uk [10]

Answer: Only B

============================================

Explanation:

For situation A,

x is the input and it represents the student's name.
y is the output and it represents the colors the student likes.

The pairing (x,y) tells us what a certain student likes in terms of color.

For example, the point (Allen, Red) tells us that Allen likes the color red. We could also have (Allen, Green) telling us he also likes green. Because the input "Allen" maps to more than one output, this means situation A is not a function. A function is only possible if any given input maps to exactly to one output. The input must be in the domain. The domain in this case is the set of all students in the classroom.

In contrast, Situation B is a function because a student will only have one favorite math teacher. I'm interpreting this to mean "number one favorite" and not a situation where a student can select multiple favorites.
