The congruent statements given are:
It is required to state what statement will be needed to make sure the triangles are congruent by AAS.
Recall the Angle-Angle-Side (AAS) Theorem:
From the theorem, it follows that a non-included pair of sides will be required.
Hence, the required pair of sides to be compared are:
The third choice is the correct option.
To find the number of solutions of a system of linear equations you need to identify the slope (m) in each equation:
-If the slope is the same in both lines the system has no solution
-If the slope is different in the lines the system has one solution
-If the equation are the same (incluided the value of b) the system has infinitely many solutions
You have the next equations:
Write the equations in slope-intercept form y=mx+b (solve for y).
First equation:
Second equation:
Answer:
False
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 problem
Sample of 121, which is higher than 30.
So we do not need to know anything about the shape of the distribution in order to make an interval estimate of the mean of all the account balances.
So the answer is False
