raketka [301]

6 for 2 dollars
Now, we need to set up a proportion.

6/2 = x/6

Cross multiply.

6*6 = 36
2*x = 2x

2x= 36

2x/2 = 36/2
x= 36/2
x= 18

Final answer: He would get 18 Tala

18 is the answer! :)

Among 9 electrical components exactly one is known not to function properly. If 3 components are randomly selected, find the pro

kozerog [31]

Answer:

P=0.66

Step-by-step explanation:

We know that Among 9 electrical components, exactly one is known not to function properly. If 3 components are randomly selected.

We calculate the probability that all selected components function properly.

We calculate the number of possible combinations:

$C_3^9=\frac{9!}{3!(9-3)!}=84$

We calculate the number of favorable combinations:

$C_3^8=\frac{8!}{3!(8-3)!}=56$

Therefore the probability is:

$P=\frac{56}{84}\\\\P=0.66$

1. In right triangle ABC, altitude CD is drawn to hypotenuse AB. If DB = 3<br> and CD = 6, find AD.

Alex Ar [27]

Answer:

3√2

Step-by-step explanation:

Given the following;

DB = 3

CD = 6,

Required

find AD.

using the similarity property of a triangle

DB/AD = AD/CD

3/AD = AD/6

3*6 = AD²

18 = AD²

AD = √18

AD= √9*√2

AD = 3√2

Hence the measure of AD is 3√2
