A horse race has 13 entries. Assuming that there are no ties, what is the probability that the four horses owned by one person f
Olin [163]
Well, there are 13 places that each horse can place. That means the first place has 13 options, second place has 12 options, third place has 11 options, etc. Though, we only care up to fourth place. When doing probability, we're multiplying in this case. So, here's the process:

How many ways all the horses can place = 13! = 6227020800
How many ways the first four places can place = 13*12*11*10 = 17160

Divide the second by the first and multiply by 100 for the probability as a percent:

(17160/6227020800)*100% ≈ <span>0.00027557319%

Which of the following have the same value as 75% of 96 choose 3 answers
ki77a [65]

For this case, we must find what amount represents 75% of 96.

Making a rule of three we have:

96 -------------> 100%

x ---------------> 75%

Where the variable "x" establishes the amount that represents 75% of 96.

x = \frac {75 * 96} {100}\\x = 72

Thus, 72 represents 75% of 96.

To find equivalent expressions that represent the same value as the 75% of 96, you should look for expressions that result in "72"

Answer:

72

D 1. Solve -4(3x - 7) = 40 for x.<br> x = -3.92<br> x= -1<br> X = 1<br> X = 3.92
Black_prince [1.1K]

\Huge{\mathscr{\boxed{\textit{Hello, There !}{}{\color{}{}}}}

<h3>ANSWER : </h3><h3></h3><h3>x = -1</h3><h3></h3><h3>\huge\bold{\textbf{\textsf{{\color{EXPLANATION :}{}}}}}</h3><h3></h3>

Solve for x, : -4(3x-7) = 40 :~x = -1

-4(3x-7) = 40

Divide both sides by : -4

\frac{-4(3x -7)}{-4} =\frac{40}{-4}

Simplify :

3x - 7 = -10

Add 7 to both sides :

3x -7~+~7=-10~+~7

Simplify :

3x = - 3

Divide both sides by 3 :

\frac{3x}{3} =\frac{-3}{3}

Simplify :

x = -1

Hope It Helps. . .
