5 times:

for example, when X=1, y=5, and when you look at the relationship between 1 and 5, 1 times 5 is 5. So, y is 5 times of x.

The median of a data set 8, 21, 17, and 13 is 15. If 17 is changed to 18, what will be the new median? a. 15.5 c. 50 b. 17.5 d.

Answer:

Option A) 15.5 is correct

The new median for the new data set is 15.5

Step-by-step explanation:

Given data set is 8,21,17,13

To find the median :

First order the given set of data into least to greatest

The ordered set is 8,13,17,21

Since the given set of data is even

We can take midvalues of data in the set

Median is the mean of two middle values in the data set

$Median=\frac{13+17}{2}$

$=\frac{30}{2}$

$=15$

Therefore Median=15 ( given )

Given that if 17 is changed to 18 then the given set of data 8,21,17,13 is changed into new set 8,21,18,13

To find the median :

First order the new set of data into least to greatest

The ordered set is 8,13,18,21

Since the given set of data is even

We can take two midvalues of new data in the set

Median is the mean of two middle values in the data set

$Median=\frac{13+18}{2}$

$=\frac{31}{2}$

$=15.5$

Therefore New Median=15.5

Therefore option A) 15.5 is correct

The new median for the new data set is 15.5

What is the product of 5the square root of 3. • 4the square root of 15.? Simplify if possible. 60the square root of 5. 20the squ

svp [43]

Correct Answer: $60 \sqrt{5}$

We are to find:

$5 \sqrt{3} *4 \sqrt{15}$

Multiplying and simplifying the radicals, we get:

$20 \sqrt{45} \\ \\ 
=20 \sqrt{9*5} \\ \\ 
=20*3 \sqrt{5} \\ \\ 
=60 \sqrt{5}$

What is 4 (5×1÷20) because I dont know lol

Whitepunk [10]

Well first we need to do whatever is in the parentheses, which in this case is: (5x1/20)

Following the order of operations (PEMDAS) we start with the multiplication, which is (5x1). We know that 5x1=5, so now we can move on to the division:

5/20, which is equal to 0.25

So now that we know the answer to the equation in the parentheses is 0.25, we can solve the whole equation.

Here is the equation simplified:

4 (0.25)

Because there is now operation indicated between the 4 and the parentheses, we can assume that multiplication is implied, so the final equation is as follows:

4x0.25=1

The final answer is: 1

Hope this helps!
