Answer: 4.4%

Step-by-step explanation:

Probability of drawing blue first is 6 in 15

Assuming you get that one, the second is 5 in 14 (as you've taken a blue one out)

If that's successful you have 5 in 13 chances of pulling another blue

As you want the first AND second AND third to happen, you multiply them…

(6/15)*(5/14)*(4/13) = 0.04395

So as a percentage, to the nearest tenth is 4.4%

Parallelogram ABCD is given. Draw line EF so that it goes through the vertex A. Point E lies on the side BC and point F lies on
tresset_1 [31]

Answer:

The proof is explained step-wise below :

Step-by-step explanation :

For better understanding of the solution see the attached figure :

Given : ABCD is a Parallelogram ⇒ AB ║ DC and AD ║ BC

Now, F lies on the extension of DC. So, AB ║ DF

To Prove : ΔABE is similar to ΔFCE

Proof :

Now, in ΔABE and ΔFCE

∠ABE = ∠FCE ( alternate angles are equal )

∠AEB = ∠FEC ( Vertically opposite angles )

So, by using AA postulate of similarity of triangles

ΔABE is similar to ΔFCE

Hence Proved.

Stefanie is painting her bedroom. She can paint 12 2/3 square feet in 2/5 of an hour. How many square feet can she paint in one
aalyn [17]

Answer:

31\frac{2}{3}

Step-by-step explanation:

since its only 2/5 of 1 hour, two 2/5 equal 4/5 so we divide the 12 2/3 by 2 to find the 1/5 which is 6 1/3

12\frac{2}{3}÷2=6\frac{1}{3}

12\frac{2}{3} +12\frac{2}{3}=25\frac{1}{3}

12\frac{1}{3} +6\frac{1}{3}=31\frac{2}{3}
