There are 10 marbles in a bag. Tyrell draws one marble out at a time without looking and replaces it in the bag. Tyrell did this

100 times. Tyrell drew red marbles 9 times, green marbles 53 times, and blue marbles 38 times. Based on this Tyrell's experiment, predict how many of each color marble is in the bag. A. 1 red,1 green, and 4 blue B. 3 red, 3 green, and 4 blue C. 1 red, 5 green, and 4 blue D. 3 red, 4 green, and 3 blue

The best choice is 'C'. If it's 1, 5, and 4, then ideally, in 100 draws, you would expect 10, 50, and 40 ... pretty close to Tyrell's actual experimental results.

The coordinates of the endpoints of directed line sergeant ABC are A(-8,7) and C(7,-13). If AB:BC = 3:2 then the coordinates of
cestrela7 [59]

The correct answer is A) (1,-5)

Further explanation:

Given points are:

A(-8,7)=(x1,y1)

C(7,13)=(x2,y2)

IT is also given that

AB:BC=3:2

Which means that B divides the line segment in 3:2

Here,

m=3

n=2

To find the coordinates of B

x_B=\frac{mx_2+nx_1}{m+n}\\ = \frac{(3)(7)+(2)(-8)}{3+2}\\=\frac{21-16}{5}\\=\frac{5}{5}\\=1\\y_B=\frac{my_2+ny_1}{m+n}\\=\frac{(3)(-13)+(2)(7)}{3+2}\\=\frac{-39+14}{5}\\=\frac{-25}{5}\\=-5

The coordinates of point B are (1,-5)

The correct answer is A) (1,-5)

Pleas help!!!! Brainliest and points!!
andreev551 [17]

Answer:

Step-by-step explanation:

Hi!

Here is the formula for point slope form: y-y1=m(x-x1)

Our slope in this case is 5, and our points are (1, 9). 1(x1) and 9(y1)

So, if we substitute our given data into the formula, here is what we will get.

y-9=5(x-1)

Thus, our answer should be:

y-9=5(x-1)

I hope this helps!

:)
