What is the midpoint of AB with A(-1, 5) and B(6, -3) A (-4, 3.5) B (1, 2.5) C (2.5, 1) D (3.5, -4)

Alina [70]

Answer:

Option C (2.5, 1) is the right alternative.

Step-by-step explanation:

The given points are:

A = (-1, 5) = (x₁, y₁)

B = (6, -3) = (x₂, y₂)

Now,

The midpoint on X-axis is:

= $\frac{x_1+x_2}{2}$

= $\frac{-1+6}{2}$

= $\frac{5}{2}$

= $2.5$

The midpoint on Y-axis is:

= $\frac{y_1+y_2}{2}$

= $\frac{5+(-3)}{2}$

= $\frac{5-3}{2}$

= $\frac{2}{2}$

= $1$

Thus the midpoint of AB is "2.5, 1".

Find the slope of the line that passes through the points (2.1) and (-1.-1).

sp2606 [1]

Answer: The slope is $\frac{2}{3}$

Step-by-step explanation:

The slope can be calculated with the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Then, knowing that the line passes through the points (2,1) and (-1,-1), we can substitute the coordinates into the formula.

In this case:

$y_2=-1\\y_1=1\\x_2=-1\\x_1=2$

Therefore, the slope of the line that passes through the points (2,1) and (-1,-1) is:

$m=\frac{-1-1}{-1-2}\\\\m=\frac{-2}{-3}\\\\m=\frac{2}{3}$

According to the general equation for conditional probability, if p(a^

Kitty [74]

This is the concept of probability and statistics;
The question requires us to get the conditional probability is given by:
P(A|B)=(P(A∩B))/P(B)
but;
P(A∩B)=3/10
P(B)=4/5
thus;
P(A|B)=(3/10)/(4/5)=3/8
The answer is 3/8

Find the difference of the complex numbers.

Amiraneli [1.4K]

Answer:

D. 7 +11i

Step-by-step explanation:

In many situations, you can treat "i" as though it were a variable. Collect terms in the usual way.

(2 +8i) -(-5-3i) = 2 +8i +5 +3i = (2+5) +(8+3)i

= 7 +11i
