If you're trying to find the missing side of the "triangle" (the distance from the house to where the ladder touches the ground), you would use the pythagorean theorem, a²+b²=c². (c is always hypotenuse)
a²+b²=c²
12²+b²=15²
144+b²=225
b²=81
√b²=√81
b=9
Answer:
40/2+14/7=27
Step-by-step explanation:
First I would break it down int 50 + 4 but either way you divide both by two
Answer:
90
Step-by-step explanation:
Find common denominators. Note that what you multiply to the denominator (bottom number of the fraction), you must also multiply to the numerator (top number of the fraction).
In this case, you are multiply 10 to both the numerator and denominator, as:
100/10 =10
Multiply 10 to the numerator:
? = 9 * 10
? = 90
90 is your answer.

Answer:
Sampling Error
Step-by-step explanation:
When the researcher randomly selected 200 people, he is creating an sample or subset from the population, that would be all the people in the earth. The error obtained was product of the fact that the analysis he made was estimated from the sample and not the whole population. There is no other mentioned factor that could cause an error, so the answer would be a sampling Error.
