Answer:
Fact Families
Step-by-step explanation:
They are fact families
Answer:
11
Step-by-step explanation:
Substitute 3 for b
23 - 4(3)
Multiply 4(3) = 12
23 - 12
Subtract
23 - 12 = 11
The ratio of the area of ∆ABC to the area of ∆DEF is; 1:100.
<h3>What is the ratio of the area of ∆ABC to the area of ∆DEF?</h3>
Since, a major criterion for similarity and congruence of triangles is that the ratio of corresponding sides are equal.
On this note, since the task content suggest that the ratio of the perimeters is; 1:10, it follows from conventional mathematics that the ratio of their areas is given as; 1²:10²; 1:100.

We know -48 came from (a)(-6), the "L" in "FOIL".
If -48 = -6a, then a = 8.
Now with a=8, go ahead and FOIL (x+8)(x-6) to find m.
Answer:
Option b
Step-by-step explanation:
Given that For a particular course, the pass rate for the 16-week format is 59%. A team of faculty examine student data from 40 randomly selected accelerated classes and determine that the pass rate is 78%.
we have to find whether taking a class in a short-term format (8 weeks instead of 16 weeks) increase a student’s likelihood of passing the course
Since pass rate for 16 weeks is 59% we check whether for 8 weeks is more than this.
So correct null and alternative hypotheses for this research question
would be:
b.H0: p = 0.59; Ha: p > 0.59
Option b is right.
