The letters of the word "UNDERDOG" can be arranged in 144 ways.
Number of ways "UNDERDOG" can be arrangedThere are only two letters that are the same which are D, then the remaining letters are 6 letters.
V, E, O are vowels
N R G
The vowels are not joined together
For N, R, G A³3
There are 4 openings A³4

What is the rat population in 1993?⇒ Number of years since = 0 ⇒ t = 0
⇒ Apply in the formula
⇒ n(0) = 73e^(0.02 × 0)
⇒ n(0) = 73e⁰
⇒ n(0) = 73,000,000 rats
=============================================================
What does the model predict the rat population was in the year 2009?⇒ Number of years since 1993 : 2009 - 1993 = 16 ⇒ t = 16
⇒ Applying in the formula
⇒ n(16) = 73e^(0.02 × 16)
⇒ n(16) = 73e^(0.32)
⇒ n(16) = 73 × 1.37712776 × 10⁶
⇒ n(16) = 100.530326 x 10⁶
⇒ n(16) = 100,530,326 rats
Answer:
Given function:
[tex]\large \text{$ n(t)=73e^{0.02t} $}[/tex]
where:
t is the number of years since 1993n(t) is the rat population measured in millionsTo calculate the rat population in 1993, substitute [tex]t = 0[/tex] into the function:
[tex]\large \begin{aligned}\implies n(0) & =73e^{0.02(0)}\\& = 73 \cdot 1\\& = 73 \sf \: million\end{aligned}[/tex]
To calculate a prediction of the rat population in 2009, first determine the value of t by subtracting the initial year of 1993 from the given year of 2009:
[tex]\large \text{$ \implies t=2009-1993=16 $}[/tex]
Substituting the found value of t into the function to find the predicted number of rats in 2009:
[tex]\large \begin{aligned}\implies n(16) & =73e^{0.02(16)}\\& = 73e^{0.32}\\& = 100.5303268...\\ & = 100.5 \sf \: million\:(1\:dp)\end{aligned}[/tex]
a rectangular mural measures 3.5ft by 5.5ft. Rosalie creates a new mural that is 1.5 ft longer. What is the perimeter of Rosalie's new mural?
The perimeter of Rosalie's new rectangular mural is given by P = 21 feet
What is the Perimeter of a Rectangle?The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.
Perimeter P of rectangle = 2 ( Length + Width )
Given data ,
Let the perimeter of the rectangular mural be represented as P
Now , the equation will be
Let the initial length of the rectangular mural be L = 3.5 feet
Let the initial width of the rectangular mural be W = 5.5 feet

For her phone service, Charmaine pays a monthly fee of $15, and she pays an additional $0.05 per minute of use. The least she has been charged in a month is
$66.90.
What are the possible numbers of minutes she has used her phone in a month?
Use m for the number of minutes, and solve your inequality for m.
Step-by-step explanation:
after subtracting the monthly fee (which she has to pay, even if she does not make a single call) we have
66.9 - 15 = $51.90
for actual phone call minutes.
1 minute is $0.05
so, in the month with the lowest charge she had used
51.9 / 0.05 = 1038 minutes for calls.
since this was the minimum, for all the numbers of minutes m she used in a month we have
m >= 1038 minutes

STRETCH YOUR THINKING on day 13 Keisha drinks 1 quart of water how does that affect the average amount of water she drinks ? EXPLAIN
The total amount of water that Kiesha drinks in 12 days is 20 quarts
The average amount of water she drinks per day is 1 2/3 quarts
The number of days that Keshia drinks at least the average amount of water is 6 days
If she drinks 1 quart of day 13, the average reduces.
What is the average ?The total amount of water drank in the 12 days can be determined by adding the quarts for each day together. When they are added together, the number is 20 quarts.
Average = total amount drank / number of days 1 2/3 quarts
New average = 20 + 1 / 13 = 21 / 13 = 1 7/13 quarts
The average reduces because the quart drank on the 13th day is less than the amount of water drank on the other days.

Paula and Pedro were selling water bottles to raise money for their school. The ratio of water bottles Paula sold to water bottles Pedro sold is 3:5. If together Paula & Pedro sold a total of 72 water bottles, how many did each sell?
Step-by-step explanation:
x = number of bottles Paula sold
y = number of bottles Pedro sold
x + y = 72
x = 72 - y
x/y = 3/5
(72 - y)/y = 3/5
5(72 - y) = 3y
360 - 5y = 3y
360 = 8y
y = 45
x + y = 72
x + 45 = 72
x = 27
so,
Paula sold 27 water bottles, and Pedro sold 45.

The value of 'a' in the P(X≤a)=0.6 is 5 because at X =5 we get a probability of 0.7. a = 5 is the answer.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
From the graph:
P(X ≤ 1) = 0.05
P(X ≤ 2) = 0.1
P(X ≤ 3) = 0.15
P(X ≤ 4) = 0.2
P(X ≤ 5)= 0.2
Add all the probability:
P = 0.05+0.1+0.15+0.2+0.2 = 0.7
P(X≤a)=0.6 (that means the value of the area under the curve 'a' is 0.6)
So the value of a should be 5
Thus, the value of 'a' in the P(X≤a)=0.6 is 5 because at X =5 we get a probability of 0.7. a = 5 is the answer.

(c) Assuming that the cube is fair, choose the statement below that is true.
O The larger the number of rolls, the greater the likelihood that the experimental probability
will be close to the theoretical probability.
O The smaller the number of rolls, the greater the likelihood that the experimental
probability
will be close to the theoretical probability.
The experimental probability will never be very close to the theoretical probability, no
X
Step-by-step explanation:
if I understand this correctly, then
1 was rolled 77 times
2 89 times
3 73 times
4 69 times
5 110 times
6 82 times
remember, a probability is always desired cases over total possible cases.
a)
the experimental probability to roll an odd number (1, 3, 5) is the number of desired cases (77 + 73 + 110) over the total cases (500).
260 / 500 = 26/50 = 13/25 = 0.52
b)
if the cube would be totally equal, so that every side has truly the same probability to appear we would have for every roll 6 total possible outcomes (1 .. 6), and 3 desired outcomes (1, 3, 5).
so the theoretical probability is
3/6 = 1/2 = 0.5
c)
if the cube is truly "fair" (all sides really have the same probability to show), then the first answer is true.
the more rolls of the die, the greater the likelihood that both probabilities will get closer and closer.
that is actually a main point of probabilities : to find the most likely behavior or structure of a large number of items or objects out of the structure or behavior of a smaller sample. or out of theoretical considerations that can be tested with smaller samples.
in euclidean geometry any three points not on the same line can lie on how many planes?
Answer:
1 plane
Step-by-step explanation:
In Euclidean geometry, three non-collinear points will define exactly one plane.
__
Two points will define a line. That line can exist in an infinity of different planes.
A third point not on the line can only lie in exactly one plane with that line.
Three non-collinear points in Euclidean geometry can lie on one unique plane.
In Euclidean geometry, any three non-collinear points (points not lying on the same line) uniquely determine a plane.
This means that there is only one plane that contains all three of those points.
So, given three non-collinear points, you can find exactly one plane that passes through all of them.
Hence, if the three points not on the same line can lie on one plane.

You must show your working.
Here are two fractions.
The correct answer is 6 / 7 as it is closer to 1.
What is a fraction?The fraction is defined as the division of the whole part into an equal number of parts.
The number near 1 will be calculated as:-
7/ 6 = 1.1666
6 / 7 = 0.8571
Difference of the first ratio from one.
1.1666 - 1 = 0.1666
Difference of the second ratio:-
1 - 0.8571 = 0.1429
