Answer: The estimate is closest to the distance d is 4.2 miles
Step-by-step explanation:
In the given image, we can see that there is a right triangle, in which d is the side opposite to the right angle (largest angle in the triangle) which means its the longest side of the triangle.
[Since side opposite to the larger angle is larger]
Therefore, by Pythagoras Theorem we have

The estimate is closest to the distance d is 4.2 miles.
$24.89
23x0.0822=1.89
23+1.89=24.89
Answer:
adjacent
Step-by-step explanation:
this just means they are next to each other, like they share a ray
Answer:
31.25% probability that the Blair family had at least 3 girls
Step-by-step explanation:
For each children, there are only two possible outcomes. Either it was a girl, or it was not. The probability of a child being a girl is independent of any other children. 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.
They had 4 children.
This means that 
The probability of a child being a girl is 0.5
This means that 
Probability of at least 3 children:





31.25% probability that the Blair family had at least 3 girls
