b=160⁰ sum of angles on a straight line add up to 180⁰

(180⁰-20⁰=60⁰)

c=125⁰ sum of angles on a straight line add up to 180⁰

i dont understand equations of parallel and perpendicular lines here's one of my teachers examples y=2x+4 (-2,1)
SIZIF [17.4K]
Parallel lines will never touch each other while perpendicular forms like an X shape. The slope for the parallel is the same while the perpendicular is a negative reciprocal. (Ex for negative reciprocal. 2/4=4/2)

Is 12.89 irrational
STatiana [176]

No.  It's the ratio of  1,289  to  100 .

Also, it can be written as a fraction with whole numbers
on top and bottom, like this:    1289 / 100 .

Also, it can be written down on paper completely, using
digits and a decimal point or fraction bar.  (You did that.)

Any one of these three facts makes it a rational number.

Using the traditional formula, a 95% CI for p1 − p2 is to be constructed based on equal sample sizes from the two populations. F
inn [45]

Answer:

49

Step-by-step explanation:

Given:

Width = 0.4

Let's take the z value of 95% which is = 1.96

Let's assume population proportion p1 and p2 = 0.5

For margin of error E, the relation between the width and margin of error is 2E.

i.e 2E = 0.4

E = 0.2

To find the sample size, n, let's use the formula :

n= \frac{z^2*(p_1(1-p_1) + p_2(1-p_2))}{E^2}

= \frac{1.96^2(0.5(1-0.5)+0.5(1-0.5))}{0.2^2}

= 48.02

≈ 49
