If two angles are complementary, then it they add up to 90 degrees.
<span>If they add up to 90 degrees, then they are right angles </span>
<span>So, If two angles are complementary, then they are right angles </span>
<span>Converse: If two angles add up to 90 degrees, then they are complementary. T </span>
<span>Inverse: If two angles are not complementary, then they do not add up to 90 degrees T </span>
<span>Contrapositive: If two angles do not add up to 90 degrees, then they are not complementary angles T </span>
<span>Hope this helps! ;D</span>
Answer:
A
Step-by-step explanation:
That is the only rate that has the correct format.
Answer:
the 3rd one -6, -3.2, 0.4 4.8
Step-by-step explanation:
this is because in the negatives -6 is less then -3.2 but positive 0.4 is greater then -3.2 so even if it looks like larger number if there is a negative sign in front if that number it is a smaller number then a number that looks smaller but has a negative sign in front of it.
Answer:
28.75% probability that none of the three randomly selected households own a cat
Step-by-step explanation:
For each household, there are only two possible outcomes. Either it owns a cat, or it does not. The probability of a household owning a cat is independent of other households. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
34% owned a cat
This means that 
Three households are selected
This means that 
What is the probability that none of the three randomly selected households own a cat?
This is P(X = 0).
28.75% probability that none of the three randomly selected households own a cat
