Answer: 0.05 or 5% chance that a randomly selected student is a senior that works.

Step-by-step explanation: Simply just count up the total amount of students (which ends up being 100), and compare it to the amount of seniors that work. Then, divide the number of seniors that work by the total amount of students, like so: 5/100. That gives you 0.05 or 5%.

What sequence is modeled by the graph below?
Lady bird [3.3K]

ANSWER

a_n= \frac{1}{2}( {2}^{n - 1} )

EXPLANATION

The corresponding ordered pairs from the graph are:

(2,1) (3,2) (4,4) (5,8)

The y-values are:

1,2,4,8

The first term term is the term before 1,this has to be.

a_1= \frac{1}{2}

The common ratio is

r =  \frac{2}{1}  = 2

The nth term is given by

a_n=a_1 {(r}^{n - 1} )

Let's substitute the values to get,

a_n= \frac{1}{2} \times  {(2}^{n - 1} )

This simplifies to,

a_n= \frac{1}{2} {(2}^{n - 1} )

The pyramid shown has a square base that is 12 inches on each side. It has a surface area of 336 square inches. What is the slan
blagie [28]
Let b and h represent the length of the side of the base and the slant height, respectively. Then the total surface area is
  A = b² + 4*(1/2)bh
  A = b² +2bh

Substituting the given numbers, you have
  336 = 12² +2·12·h
  192 = 24h . . . . . . . . . subtract 12² = 144
  8 = h . . . . . . . . . . . . . divide by 24

The slant height is 8 inches.
