Answer:

t=2Q-sr/r

Step-by-step explanation:

We are to make t the subject of formula from the given question

Q=r/2 (s+t)

Q=Sr+tr/2

Cross multiply

2Q=Sr+tr

2Q-sr=tr

t=2Q-sr/r

A two-way frequency table is shown below that displays the relationship between the region of the country in which people live a

nataly862011 [7]

Answer:

13%

Step-by-step explanation:

Given the two way frequency table :

Country Music Rock Total

West 26 15 41

East 24 22 46

South 7 33 40

North 41 25 66

Total 98 95 193

From. The table :

n(West n Country music) = 26

n(Total) = 193

P(West n Country music) = n(West n Country music) / n(Total)

P(West n Country music) = 26 / 193

= 0.1347

= 13.47%

= 13%

Suppose the length of segment BE is 11 cm. Which is the BEST ESTIMATE for segment GH?

JulijaS [17]

Answer: C) 5.5 cm.

Step-by-step explanation:

From the given , it can be clearly seen that in triangle DBE , G and H are the midpoints of segment DB and DE respectively.

Also, GH is parallel to BE. [By Converse of Basic proportionality theorem]

Length of BE= 11 cm.

Further more,

$\dfrac{DB}{DG}=\dfrac{BE}{GH}\\\\\Rightarrow\dfrac{2DG}{DG}=\dfrac{11}{GH}\ \ [{DG=GB,\therefore\ DB=2DG }]$

$\Rightarrow\ \dfrac{2}{1}=\dfrac{11}{GH}\Rightarrow\ GH=\dfrac{11}{2}=5.5\text{ cm}$

Hence, the BEST ESTIMATE for segment GH is 5.5 cm.

Note :

Converse of Basic Proportionality Theorem says that when a line (or a segment) divides any two sides of a triangle in equal proportion then the line ought to be parallel to the remaining third side.
