Since it is 10 less and you are trying to find out your number, you add 10.
71+10= 81
So, your number is 81.
Answer:
Approximately normal for large sample sizes
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this question:
The distribution is unknown, so the sampling distribution will only be approximately normal when n is at least 30.
So the correct answer should be:
Approximately normal for large sample sizes
Answer:
See attached picture
Step-by-step explanation:
The equation f(x) = 0.5(4)x is most likely 
. This is an exponential. To graph the function, test the points -1, 0, and 1. Then connect.
Answer:
The converse of Pythagorean Theorem states:
<em>If the square length of the longes side of a triangle is equal to the sum of the squares of the other two sides, then it's a right triangle.</em>
<em />
We use the converse of Pythagorean Theorem to prove that a triangle is a right triangle. It's like the inverse use of the theorem. Often, this theorem is used to find the length of a side of a triangle when we already know it's a right triangle. However, when we don't know that is a right triangle, we use the converse to prove it.
Answer:
6(12+8)
Step-by-step explanation:
the word 'times' would indicate the multiplication of 2 numbers
the word 'sum' would indicate the addition of 2 numbers. in this case, 12 + 8 would be placed in parenthesis
hope this helps!! :)
