juin [17]

Answer:

1/18

Step-by-step explanation:

there are 12 marbles in the bag

P(choose red) = 2/12 = 1/6

P(choose blue after replacement) = 4/12 = 1/3

P(choose red, then blue with replacement) = (1/6)(1/3) = 1/18

Given (x – 7)2 = 36, select the values of x.
Aneli [31]
Regroup
2(x-7)=36
Divide both sides by two
X-7= 36/2
Simplify 36/2 to 18
X-7=18
Add 7 to both sides
X=18+7
Simplify 18+7 to 25
X = 25

How does a computer drawing program compare to using a compass and straightedge?
notsponge [240]
A computer drawing program generally has more steps compared to using a compass and straightedge, although not by much. In a computer drawing program, you can erase an error within a click of a button, compared to having to manually perfect and erase your work when using a compass and straightedge. Also, you immediately have access to an online drawing program as long as you have Internet connection and a computer compared to having to go out and buy a new compass and straightedge. Other than that, they're generally the same despite being different mediums.

Hope this helps!

Find the orthocenter of △ABC. A(2, 3), B(−4, −3), C(2, −3)
weqwewe [10]
ANSWER

\boxed { A. \: \: (2,-3) }

EXPLANATION.

The orthocenter is the point of intersection of any two altitudes of the triangle.

First, you need to determine the slope of each side of the triangle.

△ABC has vertices A(2, 3), B(−4, −3), C(2, −3).

slope \: of \: AB = \frac{3 - - 3}{2 - - 4} = \frac{6}{6} = 1

slope \: of \: AC = \frac{ 3 - - 3}{2 - 2} = \frac{6}{0}

This line has undefined slope, which means it is a vertical line.

slope \: of \: BC = \frac{ - 3 - - 3}{ 2 - - 4} = \frac{0}{6} = 0

The slope of this line is zero, meaning the line is a horizontal line.

This implies that side BC and side AC of the given triangle are perpendicular and will intersect at C since they are the altitudes of triangle ABC.

Hence the orthocentre is

(2,-3)

See diagram in attachment.
