Find the mean and median of the number

Yakvenalex [24]

Answer:

Mean Is 3 , Median Is 3

Step-by-step explanation:

The mean is the usual average, so I'll add and then divide:

0 + 1 + 2 + 3 + 4 + 5 + 6 = 21 divide by 7 you'll get 3

The median is the middle value, so first you'll have to rewrite the list in numerical order: There are seven numbers in the list, so the middle one will be the answer which is 3

0 , 1 , 2 , 3 , 4 , 5 , 6

Similar right triangle

adoni [48]

Answer: 6.25

Step-by-step explanation:

Because corresponding sides of similar triangles are proportional,

$\frac{x}{2.5}=\frac{6+4}{4}\\\\x=2.5\left(\frac{6+4}{4} \right)=\boxed{6.25}$

The slope of the line below is 2. Use the coordinates of the labeled point to

Alexus [3.1K]

Answer:

The equation of line passing through point (3 , 10) with slope 2 is y = 2 x + 4 .

Step-by-step explanation:

Given as :

The slope of a line = m = 2

The line is passing through point = $x_1$ , $y_1$ = 3 , 10

Now, <u>Equation of line in point- slope form</u>

y - $y_1$ = m × (x - $x_1$ )

Or, y - 10 = 2 × (x - 3)

Or, y - 10 = 2 × x - 2 × 3

Or, y - 10 = 2 x - 6

Or, y = 2 x - 6 + 10

Or, y = 2 x + 4

So, The equation of line y = 2 x + 4

Hence, The equation of line passing through point (3 , 10) with slope 2 is y = 2 x + 4 . Answer

Given csc(A) = 65/16 and that angle A is in Quadrant I, find the exact value of sec A in simplest radical form using a rational

charle [14.2K]

Answer:

$secA = \frac{65}{63}$

Step-by-step explanation:

$cosec A = \frac{65}{16}\\\\sin A = \frac{1}{cosecA} = \frac{16}{65}\\\\cos^2 A = 1 - sin^2 A$

$= 1 - (\frac{16}{65})^2\\\\=\frac{4225-256}{4225}\\\\=\frac{3969}{4225}\\$

$cos A = \sqrt{\frac{3696}{4225}} = \frac{63}{65}$

$secA = \frac{1}{cosA} = \frac{65}{63}$
