Answer:
96
Step-by-step explanation:
Multiply both sides of the equation by 8
move the constant to the right
calculate
divide both sides
solution
Answer:
27
Step-by-step explanation:
given value of Z=9
so, 3×9=27
Π/6+2πk
5π/6+2πk
you need to factor and use trig identities
<span>There are 10,000 (10*10*10*10) possible sequences. There are 4C3 ways, 4, of having exactly three digits be the same value. The differing digit can be any of the four positions. There are 10P2 ways, 90 (10*9), to choose the digits of the sequence since we have 10 choices for the digit to be repeated, then 9 more options or the differing digit. The product of the combination arrangements and permutation selection, 4*90, shows there are 360 sequences with three of the same digit. Thus the probability is 360/10,000 or 0.036 or 3.6%.</span>
