The principal uses a computer to randomly select the name of a student from all the students inthe school. With the computer program, it is possible to draw the name of the same student

twice. If the principal selects the name of a student from the Voyagers on the first try, what is

the probability she will draw the name of another student from the Voyagers on the second try?

answer choices

81/399

41/200

1/82

21/100

Answers

Answer 1
Answer:

Answer:

41/200 B

Step-by-step explanation:

The student never gets taken away from the count so.

first pull probability is.. 82/400 second is... 82/400 simplify by dividing by 2. Equals 41/200

Below are two different functions, f(x) and g(x). What can be determined about their slopes?f(x) Alex earns 1600 dollars in 400 hours.
x
g(x)
1
−8
5
12
9
32

Answers

Answer:

As per the statement:

Below are two different functions, f(x) and g(x).

For f(x):

Alex earns 1600 dollars in 400 hours.

\text{unit rate per hour} = (1600)/(400) = 4 dollars.

Slope of f(x) = 4

Now, find the slope of g(x):

Formula for slope is given by:

\text{Slope} = (y_2-y_1)/(x_2-x_1)

From the given tables:

Consider two values  (x, g(x)) i.e,

(1, -8) and (5, 12)

Then;

\text{Slope} = (12-(-8))/(5-1)

⇒\text{Slope} = (20)/(4) =5

⇒Slope of g(x) = 5

\text{Slope of g(x)} > \text{Slope of f(x)}

Therefore, the function g(x) has faster slope.
f(x) = 1600/400 reduces to 4....the slope of f(x) is 4

g(x) :
(1,-8)(5,12)
slope = (12 - (-8) / (5 - 1) = (12 + 8)/4 = 20/4 = 5...slope of g(x) is 5

so g(x) has a greater slope then f(x)
