Answer:

Option A - Yes this probability model is valid.

Step-by-step explanation:

Given : Sherwin manages Delaroy County Zoo. The following table shows a probability model for the number of visitors on a weekday.

To find : Is this a valid probability model?

Solution :

Probability Model

Number of visitors Probability

         0-49                   0.12

         50-99                      0.26

        100-149                    0.32

        150-199                    0.21

           200+                    0.09

The property of probability is total sum of the probability of an event is always 1.

So, we find the sum of the probability,

i.e. P=0.12+0.26+0.32+0.21+0.09=1

It satisfy the property.

Therefore, Option A - Yes this probability model is valid.

5, 3.1.24<br><br> f(x) = 3x² + 5; find f(x + 3) - [f(x) + 3]
Aleks [24]

Given that f(x) = 3x^2 + 5, we have

f(x + 3) = 3 (x + 3)^2 + 5 \\\\= 3 (x^2 + 6x + 9) + 5 \\\\= 3x^2 + 18x + 32

so that

f(x+3) - (f(x) + 3) = (3x^2 + 18x + 32) - (3x^2 + 8) \\\\= \boxed{18x + 24}

NEED HELP FAST!!!
mina [271]
Remember

we can do anything to an equation as long as we do it to both sides

try to isolate the variable

you have 2 types
x+b=c
x/b=c

fior the first type, minus b from both sides to get
x=c-b

for the second, multiply both sides by b to get rid of the fraction to get
x=cb

also remember that -x times -1=x



b.add 25 to both sides
-a=20
multiply -1
a=-20


c.
-t/8=-4
multiply both sides by 8
-t=-32
mutiply -1
t=32

d. -n/-5=-30
mulitply both sides by -5
-n=150
multiply both sides by -1
n=-150

e. multiply both sides by 12
-l=144
multiply b y-1
l=-144

Help Please!! NO LINKS AND NEED EXPLANATION!
ikadub [295]

Answer:

Function 1: None of the Above

Function 2: Quadratic

Function 3: Linear

Step-by-step explanation:

Function 1: It isn't linear because the y-axis doesn't go up or down at a constant rate, it isn't quadratic because it doesn't have a vertex, and it isn't exponential because it doesn't continue going up.

Function 2: It has a vertex-(6,32)

Function 3: The y-axis goes up at a constant rate of 6.
