If you flip a coin and roll a 666-sided die, what is the probability that you will flip a heads and roll an even number?
Answer:
334/667
Step-by-step explanation
chances of getting heads is 1/2
chances of getting an even number is 333/666
simply add them up
Answer:
1/4
Step-by-step explanation:
i’m assuming u meant a 6 sided die. the probability of flipping a heads would be 1/2. the probability of rolling an even number is 3/6. 3/6 times 1/2 is 3/12 or 1/4

Please help me create the rational function that fits this graph!
PLEASE LOOK AT FILE ATTACHED!
WILL GIVE BRAINLIEST! THANK YOU
Answer:
According to the picture, we can have the function form as:
y = ax^2 + bx + c
The y-intercept is (0, 2) => c = 2
=> y = ax^2 + bx + c
The x-intercept is (-2, 0)
=> 4a - 2b = 0 (1)
The graph goes through (1, 1.5)
=> a + b + 2 = 1.5
=> a + b = -0.5 (2)
From (1) and (2)
=> 4a - 2(-a - 0.5) = 0
=> 6a + 1 = 0
=> a = -1/6 => b = -0.5 - (-1/6) = -1/2 + 1/6 = -15/30 + 5/30 = -10/30 = -1/3
=> y = (-1/6)x^2 -(1/3)x + 2
Hope this helps!

A cone has a radius of 5.1 inches and a height of 5 inches.
What is the volume of the cone?
Use 3.14 for pi. Round to the nearest tenth.
Answer:
V = 136.1
Step-by-step explanation:
Use the formula [tex]V = \frac{1}{3}\pi r^{2} h[/tex]
The solution is, the volume of the cone is 136.2inch^3.
What is volume of cone ?The formula for the volume of a cone is ⅓ r2h cubic units, where r is the radius of the circular base and h is the height of the cone.
here, we have,
A cone has a radius of 5.1 inches
and a height of 5 inches.
we know,
Volume = ⅓ r²h
=136.2inch^3.
Hence, The solution is, the volume of the cone is 136.2inch^3.

Bart recorded the amount of rain that fell in a desert in each month for one year. What was the total amount of rainfall in the desert that year? Line plot named as ALTDCMonthly Rainfall Amounts in One YearALTDC shows a number line from 0.0 to 1.1. The number line is divided into 22 equal parts. 1 dot on 0.4, 2 dots on 0.5, 1 dot on 0.6, 2 dots on 0.85, 1 dot on 0.95, 2 dots on 1.0, 2 dots on 1.05 and 1 dot on 1.1 is given. A. 9.85 inches B. 26.05 inches C. 7.25 inches D. 10.75 inches
Answer:
A. 9.85 inches
Step-by-step explanation:
In the graph we can see that 1 month has a rainfall of 0.4 in, 2 months have a rainfall of 0.5 in, 1 month has a rainfall of 0.6 in, 2 months have a rainfall of 0.85 in, 1 month has a rainfall of 0.95 in, 2 months have a rainfall of 1.0 in, 2 months have a rainfall of 1.05 in and 1 month has a rainfall of 1.1 in.
The total amount of rainfall in the desert that year was: 0.4 + 2*0.5 + 0.6 + 2*0.85 + 0.95 + 2*1.0 + 2*1.05 + 1.1 = 9.85 inches

Which shows two triangles that are congruent by the SSS congruence theorem? Triangles A B C and D E C are connected at point C. Angles A B C and C E D are right angles. The lengths of sides A B and E D are congruent. Triangles A B C and D E C are connected at point C. The lengths of sides A B and D E are congruent. The lengths of sides B C and C D are congruent. Triangles A B C and D E C are connected at point C. The lengths of sides A C and C E are congruent. Angles B A C and C E D are congruent. Triangles A B C and A D C share common side A C. The lengths of A B and A D are congruent. The lengths of B C and D C are congruent.
Answer:
The last case shows that the two triangles are congruent by SSS congruency theorem
Step-by-step explanation:
Triangles A B C and A D C share common side A C. The lengths of A B and A D are congruent. The lengths of B C and D C are congruent.
With this case. You have sides AB = AD, BC = DC, and then can conclude that AC= AC by reflexive property because AC is the common side.
so triangle ABC = triangle ADC by SSS congruency
----------------------------
CASE 1.) Triangles A B C and D E C are connected at point C. Angles A B C and C E D are right angles. The lengths of sides A B and E D are congruent. ---- You would only know one pair of sides and one pair of angles that are congruent.
CASE 2.) Triangles A B C and D E C are connected at point C. The lengths of sides A B and D E are congruent. The lengths of sides B C and C D are congruent. ----- You would only know 2 pairs of congruent sides.
CASE 3.)Triangles A B C and D E C are connected at point C. The lengths of sides A C and C E are congruent. Angles B A C and C E D are congruent. ---- You would only know a pair of angles and a pair of sides. Not enough for congruency.
CASE 4.) Triangles A B C and A D C share common side A C. The lengths of A B and A D are congruent. The lengths of B C and D C are congruent.

lucy rolls 2 fair dice and adds the results from each. work out the probability of getting a total of 10
Answer:
The probability of obtaining the sum of 10 is 1/12 or 0.0833
Step-by-step explanation:
Given
2 fair dice
Required
Probability of obtaining the sum of 10
To solve this, we have to list out the sample space.
Sample space is the total possible sum that can be obtained when she rolls the dice.
Let the first die be represented with S1 and the second be represented with S2.
S1 = {1,2,3,4,5,6}
S2 = {1,2,3,4,5,6}
To get the sample space, we have to add individual elements of S1 and S2.
This is done as follows.
When S1 = 1 and S2 = {1,2,3,4,5,6}
Sum = 1+1, 1+2, 1+3, 1+4, 1+5, 1+6
Sum = 2, 3, 4, 5, 6, 7
When S1 = 2 and S2 = {1,2,3,4,5,6}
Sum = 2+1, 2+2, 2+3, 2+4, 2+5, 2+6
Sum = 3,4,5,6,7,8
Using the same pattern as used above
When S1 = 3 and S2 = {1,2,3,4,5,6}
Sum = 4,5,6,7,8,9
When S1 = 4 and S2 = {1,2,3,4,5,6}
Sum = 5,6,7,8,9,10
When S1 = 5 and S2 = {1,2,3,4,5,6}
Sum = 6,7,8,9,10,11
When S1 = 6 and S2 = {1,2,3,4,5,6}
Sum = 7,8,9,10,11,12
Writing out the Sum, will give us the sample space.
Sample Space = {2, 3, 4, 5, 6, 7, 3, 4, 5, 6, 7, 8, 4, 5, 6, 7, 8, 9, 5, 6, 7, 8, 9, 10, 6, 7, 8, 9, 10, 11, 7, 8, 9, 10, 11, 12}
The sample space has a total of 36 elements
To calculate the probability of obtaining the sum of 10,
We have to count the number of 10's in the sample space
Number of 10 = 3
Probability = Number of 10 / Number of Sample Space
Probability = 3 / 36
Probability = 1/12
Probability = 0.0833
Hence, the probability of obtaining the sum of 10 is 1/12 or 0.0833
Answer:
3/36 = 1/12
Step-by-step explanation:
Total Outcome - 36
Possible Outcome - 4,6 5,5 6,4 : 3

Which expression has (x – a) as one of its factors?
A.–(x + a) – 2
B.–2(x + a)
C.(x – a) + 2
D.2(x – a)
i dont get this at all pls help im so lonely and confused...
Answer:
D
Step-by-step explanation:
When an expression is divided by its factor, there are no remainders.
Let's look at the number 6.
6= 1(6)= 2(3)
Thus, the factors of 6 are 1,2,3 and 6.
This is because 6 is divisible by all those numbers to give no remainders.
Let's look at the question again.
D. 2(x-a) is divisible by (x-a) since
[tex] \frac{2(x - a)}{x - a} = 2[/tex]
A.
[tex] \frac{ - (x + a) - 2}{x - a}[/tex]
This fraction cannot be simplified further
B.
[tex] \frac{ - 2(x + a)}{x - a} [/tex]
This fraction cannot be simplified either
C.
[tex] \frac{(x - a) + 2}{x - a} \\ = \frac{x - a}{x - a} + \frac{2}{x - a} \\ = 1 + \frac{2}{x - a} [/tex]
There is a remainder of 2 since 2 cannot be divided by (x-a). Thus, (x-a) is not a factor of this fraction.

a) Work out the size of AOD.
b) Work out the size of angle ABC and give a reason for your answer.
Thanks in advance :)
Answer:
ABC = 31
Step-by-step explanation:
Angle AOC and ABC have the angle theorem: the angle subtended at the centre of the circle is double the angle at the circumference. Its quite hard to realise the layout, because angle AOC isn't between points A and C. If angle AOC moved to the right side of line AB, it would be easier to see. Of course we cannot do this, otherwise angle AOC wouldn't be the middle anymore. Hope this helped
(a). The angle AOD is 62 degrees.
(b). The angle ABC is 31 degrees.
(a). From given diagram, It is observed that triangle AOD is a right angle triangle.
The sum of all three angles in triangle is equal to 180 degrees.
[tex]\angle A +\angle O + \angle D = 180\\\\90 +\angle AOD +28=180\\\\\angle AOD=180-90-28=62[/tex]
(b). The central angle theorem states that the angle subtended by an arc at the center of the circle is double the angle subtended at any point on the circumference of the circle.
[tex]\angle ABC = \frac{1}{2} \angle AOD\\ \\\angle ABC=\frac{1}{2}*62=31[/tex]
