the complete question in the attached figure

we know that

Two lines are parallel if they have the same slope.

So

Computing for the slope of line segment AB and line segment CD using the formula

m=\frac{(y2-y1)}{(x2-x1)}

step 1

Find the slope segment AB

A(x1, y1), B(x2, y2)

mAB=\frac{(y2-y1)}{(x2-x1)}

step 2

Find the slope segment CD

C(x3, y3), D(x4, y4)

mCD=\frac{(y4-y3)}{(x4-x3)}

step 3

If AB is parallel to CD

then

mAB=mCD

\frac{(y2-y1)}{(x2-x1)}=\frac{(y4-y3)}{(x4-x3)}

therefore

the answer is

\frac{(y2-y1)}{(x2-x1)}=\frac{(y4-y3)}{(x4-x3)}

For two line segments to be parallel, their slopes must be equal.

Therefore slope of AB must be equal to slope of CD

which is, option 3

Romashka-Z-Leto [24]

Answer:

Test statistic = 1.664

Step-by-step explanation:

The hypothesis :

H0 : μ = 47.2

H1 : μ ≠ 47.2

Given that :

Sample mean, xbar = 47

Sample size, n = 250

Standard deviation, σ = 1.9

The test statistic :

(xbar - μ) ÷ (σ/√(n))

T = (47 - 47.2) ÷ (1.9/√(250))

T = (0.2 / 0.1201665)

Test statistic = 1.664

Answer Q3:

A) 2/6

This decimal would be written as 0.33333333 and on.

I don't get number 4 but I'm pretty sure its A because 12 times 12 is 144 and and you have to add the 18.
