Answer:
8
Step-by-step explanation:
The numbers in order
1, 2, 3,4,4,6,7,[8,]10,11,12,12,15,15,22
262.5 miles
explanation 1/4 is half of 1/2 so 52.5 is half of 105 and then 210 for an hour of travel
The answer is about 19049
GIVEN :
a = 1/√10 ( 3i + k) and
b = 1/7 ( 2i + 3j - 6k)
TO FIND :
( 2a- b) . [ ( a x b ) x ( a + 2b)]
SOLUTION :
◆Going with the equation given,
( 2a - b) . [ ( a x b ) x ( a + 2b)]
= (2a - b) [( a×b×a) + 2(a×b)×b]
◆BAC - CAB RULE,
A×B×C = B( A.B ) - C(A.B )
= (2a- b ) [ (b (a.a ) - a (a.b ) + 2b ( a.b) -2b (a.b]
Solving further
= (2a - b )(b - 2a)
= -4a.a -b.b
=-5.
Answer:
( 2 - b) . [ ( a x b ) x ( a + 2b)] = -5

Answer:</h2><h2>
The value of P (B) = 0.22</h2>
Step-by-step explanation:
The probability of event A, P (A) = 0.75
The probability of events A and B, P (A ∩ B) = 0.165
The probability of event B, P (B) = ?
Independent events are those where the probability of A event occurring doesn't affect the probability of B event. In other words, they don't depend upon each other and are independent.
By formula,
P (A ∩ B) = P (A) . P (B)
By substituting the values to the above equation, we get
0.165 = 0.75 * P (B)
P (B) = 0.22
