141.5 When finding the mean add all of the the numbers then divide by how many numbers are there!

Mean is an average.

In order to find mean we must add up all the numbers and divide by how many numbers there are.

82 + 105 + 247 + 119 + 94 + 202

Adding them together and we get...

849.

We can see that we have 6 numbers.

849/6

849 divided by 6 is...

141.5

That is the mean.

Suppose a card is drawn at random from a standard deck. The card is then shuffled back into the deck. Then for a second time a c

Oduvanchick [21]

Answer:

Probability = 0.0288

Step-by-step explanation:

For the first draw.

There are total of 52 cards in a deck of cards and a total of 26 red cards in a deck of cards.

Probability of drawing a red= 26/52

Probability = 0.5

For the second draw. Actually the initial card drawn was replaced. Total number of face cards are 12.

Probability of drawing a face card = 12/52= 0.23076923

For the third draw .

There are 13 diamond cards in total.

Probability of a diamond = 13/52

Probability = 0.25

Probability of red,face, diamond= 0.5*0.23076923*0.25=0.028846

To four decimal place = 0.0288

What is the point-slope form given the following slope and a point on the line? m = 3/7 , (7, -4)

GarryVolchara [31]

Answer:

The equation is y = (3/7)x - 7.

Step-by-step explanation:

Given that the point slope form of an equation is y = mx + b where m represents the gradient and b is the y-intercept. Then, you have to substitute the following values into the equation :

$y = mx + b$

$let \: m = \frac{3}{7} ,x = 7,y = - 4$

$- 4 = \frac{3}{7} (7) + b$

$- 4 = 3 + b$

$- 4 - 3 = b$

$b = - 7$

Prove Theorem 3: Corresponding angle bisectors of similar triangles are proportional and their ratio is equal to the ratio of si

RoseWind [281]

Answer:

The proof is given below.

Step-by-step explanation:

Given the two triangles which are similar we have to prove that the ratio of their angle bisectors and the side or we can say that the ratio of their altitude are proportional.

In ΔABP and ΔDEQ

∠1=∠2 (Given)

∠3=∠4 (each 90°)

By AA similarity rule ΔABP≅ΔDEQ

As if the two triangles are similar then their corresponding sides are proportional

⇒ $\frac{AB}{DE}=\frac{AP}{DQ}=\frac{BP}{EQ}$

Hence, Corresponding angle bisectors of similar triangles are proportional and their ratio is equal to the ratio of altitude.
