Answer:

x = 3.5

Step-by-step explanation:

Since the triangles are similar we can use ratios to solve

4 7

------ = ------

(4+2) ( 7+x)

Using cross products

4(7+x) = 7*(4+2)

Distribute

28+4x = 42

Subtract 28 from each side

4x = 42-28

4x= 14

Divide by 4

4x/4 = 14/4

x = 7/2

Use each picture or description of a triangle, write and solve an equation in order to find the number of degrees in each angle

TiliK225 [7]

4x + 7x - 2 + 5x - 10 = 180

16x - 12 = 180

16x = 192

x = 12

m<A= 4x = 4(12) = 48

m<B = 7x - 2 = 7(12) - 2 = 84 - 2 = 82

m<C = 5x - 10 = 5(12) - 10 = 60 - 10 = 50

Let f(x) = x2 − 3x − 7. Find f(−3)

uranmaximum [27]

Substituting -3 for x, we have: (-3)^2-3*-3-7. This simplifies to 9+9-7, or 11.

What is the center of the data?

satela [25.4K]

Answer:

$Median = 13$

Step-by-step explanation:

Given

See attachment for dot plot

Required

The center of data

This implies that, we calculate the median

From the attached plot,

$n = 13$ --- number of observation

So, the median is:

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

$Median = \frac{13 + 1}{2}$

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

$Median = 7th$

The median is at the 7th position

At the 7th position, is 13

Hence:

$Median = 13$
