In a parallelogram, opposite angles are congruent.
This means that the four angles of the parallelogram are:
Moreover, the sum of the interior angles of a polygon with n sides is 180(n-2). So, the sum of the interior angles of a parallelogram is 360.
This means
And since , we have
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
Y=square root of x
All the others would be a straight line with an unchanging slope (meaning they're linear). Y=rootx is not linear.
I hope this Helps!
Answer:Assuming x is an odd number, the expression for three consecutive odd numbers would be x+x+2+x+4, which simplifies to 3x+6.ep-by-step explanation:
<em><u>Answer:</u></em>
4 or 7 (Check the explanation to see which one your equation <em>actually</em> is.
<em><u>Step-by-step explanation:</u></em>
One thing I want to clarify for you, It's Evaluate, not Avaluate.
Okay so, we want to find the value of 2^3x-1 and we know x = 1.
You didn't really clarify if the expression was or , so I'll be doing both:
For , we should plug in x to get and then simplify to get .
2 to the power of 2 or is equal to 2 * 2 or 4.
The second one, , we should plug in x to get and then to become . 2 to the power of 3 or is 8 and then minus 1 is 7.
