The probability that the sum of the dice is 9 is, 4/33.
What is dice?
Dice are little, thrown-away devices with marked sides that can rest in various locations. They are frequently employed in tabletop games including dice games, board games, role-playing games, and games of chance to provide random values.
Let two fair dice are rolled.
So the possible number of outcomes are,
(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)
(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)
(3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6)
(4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4,6)
(5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6)
(6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)
There are total 36 outcomes.
There are 33 outcomes with sum greater than 3.
The outcomes with sum greater than 9 are, 4 which are (3, 6), (4, 5), (5, 4) and (6, 3).
Hence, the probability that the sum of the dice is 9 is, 4/33.

Order the following from least to greatest -0.2, 4.22,2.02,-3/10, 4 1/8
The correct order is -3/10, -0.2, 2.02, 4.22, 4 1/8 .
Firstly we will convert the fractions into decimal units i.e
-3/10 = -0.3
41/8 = 5.125
We know that the higher the number in negative number line lower will the value of it so the -0.3 < -0.2
Now we can easily arrange these numbers according to the number line i.e;
Negatives will be first to come on number line and the correct order will be as follow :

Find the exact values of sin theta , sec theta, and tan theta.
- 13/12 is the value of trigonometric functions sec θ .
What do trigonometric functions mean?
The functions of an angle in a triangle are known as trigonometric functions, commonly referred to as circular functions. In other words, these trig functions provide the relationship between a triangle's angles and sides.r = √( -12 - 0 )² + ( 0 - 5 )²
r = √144 + 25
r = √169
r = 13
Now we can calculate the trigonometric functions
sinθ = y/r = 5/13
cosθ = x/r = -12/13
tan θ = y/x = - 5/12
cot θ = x/y = -12/5
sec θ = r/x = - 13/12

Answer:
[tex]\left.\dfrac{\text{d}x}{\text{d}t}\right|_{h=2}\approx0.184\; \sf m/s[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{9 cm}\underline{Pythagoras Theorem} \\\\$a^2+b^2=c^2$\\\\where:\\ \phantom{ww}$\bullet$ $a$ and $b$ are the legs of the right triangle. \\ \phantom{ww}$\bullet$ $c$ is the hypotenuse (longest side) of the right triangle.\\\end{minipage}}[/tex]
Given variables:
a = length of the ladder.h = height of the ladder's top at time t.x = distance of the ladder from the wall at time t.Given a = 8.9, use Pythagoras Theorem to create an equation for x² in terms of h²:
[tex]\implies x^2+h^2=a^2[/tex]
[tex]\implies x^2+h^2=8.9^2[/tex]
[tex]\implies x^2+h^2=79.21[/tex]
[tex]\implies x^2=79.21-h^2[/tex]
Differentiate with respect to h:
[tex]\implies 2x\dfrac{\text{d}x}{\text{d}h}=0-2h[/tex]
[tex]\implies \dfrac{\text{d}x}{\text{d}h}=-\dfrac{2h}{2x}[/tex]
[tex]\implies \dfrac{\text{d}x}{\text{d}h}=-\dfrac{h}{x}[/tex]
Given:
[tex]\dfrac{\text{d}h}{\text{d}t}=-0.8\; \sf m/s[/tex]
Therefore:
[tex]\begin{aligned} \dfrac{\text{d}x}{\text{d}t}&=\dfrac{\text{d}x}{\text{d}h}\times \dfrac{\text{d}h}{\text{d}t}}\\\\ \implies &=-\dfrac{h}{x} \times -0.8\\\\ &=\dfrac{0.8h}{x} \end{aligned}[/tex]
Calculate x when h = 2:
[tex]\implies x^2=79.21-2^2[/tex]
[tex]\implies x^2=79.21-4[/tex]
[tex]\implies x^2=75.21[/tex]
[tex]\implies x=\sqrt{75.21}[/tex]
Substitute the values of h and x into the equation for dx/dt:
[tex]\implies \dfrac{\text{d}x}{\text{d}t}=\dfrac{0.8 \times 2}{\sqrt{75.21}}=0.1844939751[/tex]
Therefore, the rate of the ladder's distance from the wall is 0.184 m/s (3 d.p.)
15. Mindy has $20. She spent $8.64 including tax to buy a new card game. She
needs to set aside $10 to buy lunch. If Lollipops cost $.28 including tax, what is
the maximum number of lollipops that Maya can buy?
Step-by-step explanation:
she can therefore only spend $10 of the $20.
$8.64 are adjust gone for the card game.
that leaves us with
10 - 8.64 = $1.36
to spend on lollipops.
1 lollipop costs $0.28
so, she can buy a many lollipops as times 0.28 fits into 1.36 :
1.36 / 0.28 = 4.857142857...
that means she can buy 4 lollipops max.
she would keep some change, but not enough to buy a 5th lollipops, because then she would have to cut into the $10 reserve she needs for lunch.
for 5 lollipops she would need $1.40 (5×0.28).

3. In a survey of 1000 eligible voters selected at random, it was found that 8% had a college degree. Additionally it was found that 80% of those who had a college degree voted in the last presidential election. Whereas 55% of the people who did not have a college degree voted in the last presidential election. Assuming that the poll is representative of all eligible voters, find the probability that an eligible voter selected at random voted. Draw a diagram to represent this situation.
a) If you randomly chose an eligible voter from this group, what is that probability that they have a degree and did not vote?
b) If you randomly chose an eligible voter from this group, what is the probability that they voted?
c) If you randomly chose a person who voted in the presidential election, what is the probability that they had a college degree?
hello, i'm sorry but i can't graph the diagram but here are the answers for a-c :)
A. 8%
B. 39.6%
C. 58.4%
step by step:
A. Calculation to determine the probability of The voter had a college degree and voted in the last presidential election.
P = 80/1,000
P=0.08*100
P=8%
Therefore the probability of The voter had a college degree and voted in the last presidential election will be 8%
B. Calculation to determine the probability of The voter did not have a college degree and did not vote in the last presidential election.
P =396/1000
P=0.396*100
P=39.6%
Therefore the probability of The voter did not have a college degree and did not vote in the last presidential election will be 39.6%
C. Calculation to determine the probability if The voter voted in the last presidential election.
P = 584/1,000
P=0.584*100
P=58.4%
Therefore the probability if The voter voted in the last presidential election will be 58.4%

What is area of circle?
For measuring the area occupied by a circular field or plot, use the area of a circle formula.

We can determine the boundary length, or the circle's circumference, using the area formula.
Here area of circle

Differentiating 1 with respect to to time then
=> [tex]\frac{dA}{dt}= 2\pi r\frac{dr}{dt}[/tex]
If the radius is increasing at a constant rate 3.3ft/sec then after 6.4 seconds, radius is
=> 6.4*3.3=21.12 ft.
We know [tex]\frac{dr}{dt}= \frac{3.3ft}{sec}[/tex] and so ,
=> [tex]\frac{dA}{dt}[/tex] = 2*[tex]\pi[/tex]*21.12*3.3=139.4 [tex]\pi[/tex] [tex]ft^2[/tex]sec.

The measure of angle 11x+1 is 100°.
According to the question,
We have the following information:
We have a figure where two parallel lines are divided by a line. We know that the vertically opposite angles are equal. And when two parallel lines are cut by another line then the alternate interior opposite angles are equal.
Now, we have 10x+10 as the alternate opposite interior angle to 11x+1.
So, we have the following expression:
10x+10 = 11x+1
11x-10x = 10-1
x = 9
Putting the value of x in 11x+1:

What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
There are more than 200 pages but fewer than 800 in my book.
And, All the digits of my number are the same and the number is divisible by 9.
Now,
Let a number with three same digit = xxx
So, We get;
