Answer:

Step-by-step explanation:
We have the product,
.
It is known that,
'When we multiply a scalar with a matrix, the scalar is multiplied by each element of the matrix'.
So, we get,
.
⇒ 
⇒ 
So, the resulting product is
.
Total number of outcomes of 7 from 10 = 10*9*8 / 3*2*1 = 120
probability of each outcoe is 0.85^7* (0.15)^(3) = 0.0010819
Required probability = 120 * 0.0010819 = 0.1298
Answer:
Option (2)
Step-by-step explanation:
Radius of the circular base of the cone = 
Given in the picture,
Diameter of the circular base = 8 cm
Height of the cone = 6 cm
Therefore, radius of the cone = 
= 4 cm
Option (2) will be the correct option.
So we have to use the distributive property:
We ll get -12x-9-2x+5+18x-24
Now we have to combine like terms
-12-2x+18x=4x
-9+5-24=-28
Therefore our answer is:
Y=4x-28
