Congruence Properties
In earlier mathematics courses, you have learned concepts like the commutative or associative properties. These concepts help you solve many types of mathematics problems. There are a few properties relating to congruence that will help you solve geometry problems as well. These are especially useful in two-column proofs, which you will learn later in this lesson!
The Reflexive Property of Congruence
The reflexive property of congruence states that any shape is congruent to itself. This may seem obvious, but in a geometric proof, you need to identify every possibility to help you solve a problem. If two triangles share a line segment, you can prove congruence by the reflexive property.
Answer:
The answer is true.
Step-by-step explanation:
Sample methods that embody random sampling are often termed probability sampling methods.
Yes this is a true statement.
Random sampling means picking up the samples randomly from a whole population with each sample having an equal chance of getting selected.
For example- selecting randomly 10 students from each class of a school, to survey for the food quality in school's cafeteria.
And this is a type of probability sampling methods. Other types are stratified sampling, cluster sampling etc.
Answer:
Step-by-step explanation:
Assuming that:
the promotion will be considered to be a success if more than 10% use the coupons received.
and coupons are sent to 100 credit card customers.
Then, the null hypothesis and alternative hypothesis is:
sample size n = 100
Using the eagle file data;
the no of people in the sample who use the coupon = 13
then,
Test statistics can be computed as:
At ∝ = 0.05
Since, P-value is greater than ∝, then we fail to reject 
.
Therefore, Eagle should not go with the promotion; a larger sample should be taken.
Answer:
-12
Step-by-step explanation:
The slope of a line is just the difference of y-values divided by the difference of x-values
The answer to your question would be C.$100
