Answer: [tex]\dfrac{11}{36}[/tex]
Step-by-step explanation:
Total outcomes for rolling a pair of six-sided dice n(S)= 6 x 6 =36
Let A be the event that the first die is one and B be the event that the sum of the dice is eight.
A = {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)}
P(A)= [tex]=\dfrac{n(A)}{n(S)}=\dfrac{6}{36}[/tex]
B= {(2,6), (6,2), (3,5), (5, 3), (4,4)}
P(B)= [tex]=\dfrac{n(B)}{n(S)}=\dfrac{5}{36}[/tex]
A ∩ B = Ф
P(A ∩ B)=0
P(A or B)= P(A)+P(B)+P(A∩ B)
[tex]=\dfrac{6}{36}+\dfrac{5}{36}+0\\=\dfrac{11}{36}[/tex]
Hence, P(A or B) = [tex]\dfrac{11}{36}[/tex]
3/4 - 4x + 1/2x - 1/2 + 1/2x Combine the like terms to simplify. Show your work
If you mean,
[tex] \frac{3}{4} - 4x + \frac{1}{2} x - \frac{1}{2} + \frac{1}{2}x[/tex]
Then the answer would be,
[tex] \frac{1}{4} - 3x[/tex]
But if you mean,
[tex] \frac{3}{4} - 4x + \frac{1}{2x} - \frac{1}{2} + \frac{1}{2x} [/tex]
Then the answer would be,
[tex] \frac{1}{4} - 4x + \frac{1}{x} [/tex]

Step-by-step explanation:
So what you need to do is mark to points on the graph. For example (9,4) and (18,8). The run would be 9 and the rise would be 4. Gradient = rise/run which is 4/9. So that's the gradient. Now it asks for the equation. The formula for an equation is y=mx+c m= the gradient and c = the y-intercept (the y intercept is where the line meets the axis so it would be 0) so the answer is: y=4/9x+0.

What is the difference between spherical and hyperbolic geometry?In spherical geometry, there aren't any such strains. In hyperbolic geometry, there are at least awesome traces that bypass via the point and are parallel to (in the same plane as and do no longer intersect) the given line.
Why is hyperbolic geometry important?A study of hyperbolic geometry enables us to break away from our pictorial definitions with the aid of supplying us with a world in which the pics are all changed but the exact means of the words used in every definition stay unchanged. hyperbolic geometry facilitates our to focus on the importance of phrases.

What is the value of x
Answer:
The answer is 60
Step-by-step explanation:
reasoning: we know that in a triangle all three sides add up to 180
SO we can divide 60 by 180 which is 3.
we can also do 180-60 which is 120 then find out what is half of 120 which is 60.

Complete the following statement about the Empirical Rule.
According to the Empiricalâ Rule, if a distribution isâ bell-shaped, then approximately _______________ of the data will lie within 1 standard deviation of theâ mean; approximately ____________ 95% 99.7% 68% of the data will lie within 2 standard deviations of theâ mean; approximately ______________ 68% 95% 99.7% of the data will lie within 3 standard deviations of the mean.
Answer:
1. 68%
2. 95%
3. 99.7
Step-by-step explanation:
Standard deviation of mean will be 68%, 95%, and 99.73% respectively.
What is Empirical Rule?A statistical rule known as the empirical rule, which is also known as the three-sigma rule or the 68-95-99.7 rule, states that almost all observed data for a normal distribution will be within three standard deviations of the mean or average.
Given according to the empirical rule, 68% of observations will fall within the first standard deviation (µ ± σ), 95% will fall within the first two standard deviations (µ ± 2σ), and 99.7% will fall within the first three standard deviations(µ ± 3σ) .
Hence SD of mean will be 68%, 95%, and 99.73%
