Envision this as a right triangle, with one leg of 12 miles, and the other 16 miles. Solve using the Pythagorean Theorem a²+b²=c²:
12²+16²=c²
400 = c²
20=c...they live at least 20 miles from each other.
Answer:
yes
Step-by-step explanation:
The value 8 is the solution to the equation because plugging 8 into the equation in place of the unknown variable x like 16(8) will equal 128.
Based on the venn diagram of siblings, the probability of having a brother and sister is c. 0.33.
<h3>What is the probability of brother and sister?</h3>
The probability of having a brother and sister can be found as:
= Number of those with brother and sister / Total number of people in poll
Solving gives:
= 10 / (8 + 10 + 5 + 7)
= 10 / 30
= 0.33
In conclusion, the probability of having a brother and sister is 0.33.
