Answer:

13 students

Step-by-step explanation:

We have a list of four numbers: 1, 2, 3, 4. If 50 persons were to pick a number randomly, it means that the probability of picking any of the numbers is 0.25.

Therefore, from 50 students, 0.25*50 = 12.5 ≈ 13 students aproximately would choose the same number as I did.

How to multiply numbers with exponets and different bases
o-na [289]
When the bases are diffenrent and the exponents of a and b are the same, we can multiply a and b first:
a n ⋅ b n = (a ⋅ b) n
Example:
32 ⋅ 42 = (3⋅4)2 = 122 = 12⋅12 = 144

When the bases and the exponents are different we have to calculate each exponent and then multiply:
a n ⋅ b m
Example:
32 ⋅ 43 = 9 ⋅ 64 = 576

Hello!

<u>What is an x-intercept</u>:

 ⇒ <em>value of x</em> when the <em>value of y</em> equals '0'

       8x + 5y=25\\8x+5(0)=25\\8x=25\\\\x=\dfrac{25}{8}

  x-intercept is <u>25/8</u>

<u></u>

<u></u>

<u>What is a y-intercept:</u>

 ⇒ <em>value of y</em> when the <em>value of x</em> equals '0'

       8x+5y=25\\8(0)+5y=25\\5y=25\\y=5

   y-intercept is <u>5</u>
