Answer:
And replacing we got:
Step-by-step explanation:
For this case we have the following info given:
represent the sample size selected
represent the population proportion
We want to find the standard error and we can use the distribution for the sample proportion and for this case since the sample size is large enough and we satisfy np>10 and n(1-p) >10 we have:
And the standard error is given;
And replacing we got:
Answer:
2
Step-by-step explanation:
You count terms that are seperated by - and + signs. Any type of fraction is considered one term.
So you count 8y as one term and the rest is a whole fraction so you also count that as one term.
You add all the terms together and you have 2 terms in this equation.
Hope this helped :)
Answer:
3 3/5
Step-by-step explanation:
9/13 ÷5/26
We can use copy dot flip
Take the first number and copy it
9/13
Change the division to multiplication
9/13 *
Flip the second number
9/13 * 26/5
I will rewrite the fractions for easier cancellation
9/5 * 26/13
9/5 * 2/1
18/5
5 goes into 18 3 times 3*5 = 15 with 3 left over
3 3/5
Types of Triangles (Angles):
---Acute = all angles are less than 90 degrees
---Right = one angle is equal to 90 degrees
---Obtuse = one angle is greater than 90 degrees
Types of Triangles (Side Lengths):
---Equilateral = all sides are the same length
---Isosceles = two sides are the same length
---Scalene = all sides are different lengths
The following triangle is obtuse and scalene. It has one angle that is greater than 90 degrees and its sides are all different lengths.

X^2-7x+12 because when you distribute its
X*X +
(X*-4)+(x*-3) +
-3*-4
