Just like regular multiplication. Since 8.33 has two spaces after the decimal point, the answer would also have two spaces after the decimal point.
Answer:
y≤-3
Step-by-step explanation:
5 - 8y ≥ 11 -6y There isn't anything to distribute
So bring the variable to one side of the inequality
In this case add 6 to both side
5 -2y ≥ 11
now subtract 5 in both side
-2y ≥ 6
now you have to divide by -2 so you have have to flip the sign since you are dividing by a negative number
y≤-3
No, that would be an invalid inference because he actually sampled from only half of the total population not the entire population.
so 12% of the 50% he sampled would be valid, but since he did not use the entire population, the results cannot affect all of them.<span />
Answer:
4, 7 ,2
Step-by-step explanation:
This will be:
[√9]/[(3-2i)+(1+5i)]
simplifying the above we get:
√9/(3+1-2i+5i)
=√9/(4+3i)
rationalizing the denominator we get:
√9/(4-3i)×(4-3i)/(4-3i)
=[√9(4-3i)]/(16+9)
=[3(4-3i)]/25
=(12-9i)/25
Answer: (12-9i)/25
