Answer:

Option (b) is correct.

The median of the given data is 14,515 ft.

Step-by-step explanation:

Given : Data for the the heights in feet of the 30 tallest mountains in the United States.

We have to find the median of the given data .

Median of the data is the middle value.

Consider the given data,

To calculate the median : First put the data in ascending order and then find the middle value.

If the number of terms is odd then the middle value is median

And if the number of terms is even then the average of two middle value is median.

We arrange the given data in ascending order,

14269 14270 14286 14294 14309 14345 14361 14370 14410 14420 14421 14433 14470 14494 14500 14530 14573 14730 14831 14950 15300 15638 15885 15979 16237 16390 16500 17400 18008 20320

Since, The number of terms are 30 (even)

Thus, The median is the average of two middle values

Here, Middle terms are 15th and 16th term,

15th term is 14500

and 16th term is 14530

Thus, Median is $\frac{14500+14530}{2}=14515$

Thus, The median of the given data is 14,515 ft.

Ms Bonilla is saving for a vacation she currently has 150 in her savings account and plans to add $25 to the account each week .

Alexandra [31]

Answer and Step-by-step explanation:

Alright, so when creating any type of math problem, it is important to identify the parts of the problem and where they go. First, we need to start by putting the problem together. We will use one of the most common forms of equations of math, also known as the linear equation of y=mx+b.

So we have: S(w)=__x + __. S(w) is also equal to f(x), which is also equal to y. So: y= __x + __.

Let's start filling this equation in. So, because it says that she will add 25 dollars each week, The problem is addition. Also, the 25 dollars each week will represent the mx in this situation. Here's why:

The x in this can stand for the amount of week she added this 25 dollars to her account. So:

y= 25x + __.

Now, we can add the 150 to the problem because that is what she started with for this one-time deal. So now we have:

y= 25x + 150.

You can now where everything is represented, but we are not done. Let's change y and x back into S(w) and w like the question asks us to have. So:

S(w)= 25w + 150.

If you want to solve this question, just replace the number of weeks in place of all w's in the equation, like this: S(2)= 25(2) + 150.

I hope that this helps.

A, B, and C are collinear, and B is between A and C. The ratio of AB to AC is 1:2 If A is at (6,3) and B is at (-1,2), what are

Maksim231197 [3]

Answer:

The coordinates of C is (-8,1)

Step-by-step explanation:

Looking at the attached image, you'd see that, AB is 1 and BC is 1, that's because we are told that ratio of AB to AC is 1:2 meaning, AC is 2 and AB is 1. Therefore for that ratio to be satisfied BC has to be 1 so that AC would be 2.

Now let's assume the coordinates of C is $(x,y)$ .
