There is a .41025...% chance of that happening. moving on the jar is not 25% filled with red balls because 25% of 36 is only 9 and he pulled out 16 red balls hence forth that is impossible if the jar is only 25% red balls 

hope this helped!!!

Which function describes the arithmetic sequence shown?
Lynna [10]

f(x)= -2x-3

Step-by-step explanation:

Step 1:

Let the sequence given here is -5, -7, -9, -11, -13 ......

Here the first term (a₁) of sequence is -5

And the common difference between the numbers in the sequence is

d= (-7-(-5)) = -7+5 = -2

Let the number of terms be x

Step 2;

To find the sequence function basic arithmetic sequence formula is

aₙ = a₁ + d( x-1)

Applying the values we get

f(X) = -5 + ((-2)(X-1))

on simplification

f(X) = -5 + (-2X+2)

f(X)= -5+2-2X

f(X)= -3-2X

If 48% of the students in a certain college are female and there are 1440 female students, what is the total number of students
Andrews [41]

Answer:

3000 students

Step-by-step explanation:

If 48% of the students are female, and there are 1440 female students, we can set up a percentage proportion, assuming x is the total amount of students.

\frac{1440}{x} = \frac{48}{100}

We can use the cross products property to find the value of x.

1440\cdot100=144000\\\\144000\div48=3000

Hope this helped!
