Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the required data are not given.

I will use the following data as an illustration of how to calculate median and range.

We have:

$x: 11, 13, 14, 15, 18, 20$

<u>Calculate range</u>

Identify the highest and the least

$Highest = 20$

$Least = 11$

So, the range is:

$Range = Highest -Least$

$Range =20-11$

$Range =9$

<u>Calculate the median</u>

The number of data we are using is 6 (i.e. even).

So, the position of the median item is:

$Median =\frac{1}{2}(n+1)$

$Median =\frac{1}{2}(6+1)$

$Median =\frac{1}{2}*7$

$Median =3.5th$

A decimal result implies that the median is the mean of the integer values before and after the result.

In this case, the median is the mean of the item at 3rd and 4th positions.

So:

$Median = \frac{14+15}{2}$

$Median = \frac{29}{2}$

$Median = 14.5$

Find the value of each variable.

insens350 [35]

Step-by-step explanation:

11)

x= 5

${y}^{2} = 2 \times {5}^{2} \\ {y}^{2} = 50 \\ y = 5 \sqrt{2}$

12)

$\tan(30 ) = \frac{9}{y} \\ y = \frac{9}{ \tan(30) } = 9 \sqrt{3} \\ {x}^{2} = {9}^{2} + {(9 \sqrt{3} )}^{2} \\ {x}^{2} = 324 \\ x = 18$

13)

$\sin(60) = \frac{x}{22} \\ x = 11 \sqrt{3} \\ \cos(60) = \frac{y}{22} \\ y = 11$

14)

${16}^{2} = {x}^{2} + {y}^{2} \\ x = y \\ {16}^{2} = 2 {x}^{2} \\ x = 8 \sqrt{2} \\ y = 8 \sqrt{2}$

15)

$\tan(30) = \frac{x}{42} \\ x = 14 \sqrt{3} \\ \cos(30) = \frac{42}{y} \\ y = \frac{42}{ \cos(30) } \\ y = 28 \sqrt{3}$

16)

${(19 \sqrt{2}) }^{2} = {x}^{2} + {y}^{2} \\ x = y \\ 722 = 2 {x}^{2} \\ {x}^{2} = 361 \\ x = 19 \\ y = 19$

Which is an equation in point-slope form for the given point and slope?

Akimi4 [234]

Answer:

The answer to your question is the letter D. (step 2)

Step-by-step explanation:

Data

P (7, 4) slope = 6

Process

1.- Write the equation of the line

y - y1 = m(x - x1)

x1 = 7 y1 = 4

2.- Substitution

y - 4 = 6(x - 7)

- Simplification

y - 4 = 6x - 42

- Solve for y

y = 6x - 42 + 4

y = 6x - 38 This is the equation in the point-slope form

3.- According to the choices the answer is letter D.
