Answer: Yes, it would be biased. If David asked the question about movies, however, it would not be.
Step-by-step explanation: It would be biased because he is asking listeners to his show who send fan mail. Fan mail is typically only sent by people who enjoy the creator. Therefor, he would be surveying only people who enjoy his podcast so the results would be heavily biased. I am unsure about how the second part of the question relates to the first part. If David were to ask the same 100 individuals about their favorite movies rather than whether or not they liked his podcast, it would not contain biased results because he or his podcast does not have anything to do with movies. :)
Answer:
The smaller number = -1
The larger number = 3
Step-by-step explanation:
Let the smaller number = a
Let the larger number = b
The larger of two numbers is 6 more than 3 times the smaller.
b = 3a + 6........... Equation 1
If the twice the larger number is increased by 3 times the smaller, the result is 3.
2b + 3a = 3........ Equation 2
Hence:
We Substitute 3a + 6 for b in Equation 2
2b + 3a = 3
2(3a + 6) + 3a = 3
6a + 12 + 3a = 3
9a = 3 - 12
9a = -9
a = -9/9
a = -1
b = 3a + 6........... Equation 1
b = 3(-1) + 6
b = -3+ 6
b = 3
Therefore,
The smaller number = -1
The larger number = 3
Hopefully, you're talking about Pythagorean theorem.
a^2 + b^2 = c^2
They gave us side a and side c, so we plug in our values
10^2 + b^2 = 16^2
You solve the exponents
100 + b^2 = 256
Subtract 100 on both sides
100 + b^2 = 256
-100 -100
You're left with:
b^2 = 156You square root both sides
b = 12.489...
We round and get our final answer:
b = 12.49
Good luck!
Answer:
Step-by-step explanation:
To get the other angles you need to do this
110+80+x+x=360
190+2x=360
2x=360-190
2x=170
X=170÷2
X=85
