Given the condition that the sum of the dice rolled is less than 8, the probability of the dice having a sum of 6 is found by considering all outcomes where the sum is less than 8 and outcomes that result in a sum of 6. The probability turns out to be 20%.
Explanation:This question involves the concept of conditional probability in mathematics. For a pair of six-sided dice, there are 36 equally likely outcomes (Because 6 faces of one die times 6 faces of the other). We are interested in the event of getting a sum of 6, given the sum is less than 8.
We first consider all the outcomes where the sum of two dice is less than 8: (1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (3,1), (3,2), (3,3), (3,4), (3,5), (4,1), (4,2), (4,3), (4,4), (5,1), (5,2), (5,3), (6,1), (6,2). There are 25 equally likely outcomes where the sum is less than 8.
Then, consider all the outcomes where the sum of the two dice is equal to 6: (1,5), (2,4), (3,3), (4,2), (5,1). There are 5 equally likely outcomes. So given the condition that the sum is less than 8, the probability of getting a sum of 6 is 5/25 or 20%.

Step-by-step explanation:
From the graph we can conclude that it is a sine or cosine function. In their standard form, these functions are given by the following equations:
[tex]y(t)=Acos(\omega t +\phi)\\\\or\\\\y(t)=Asin(\omega t+ \phi)[/tex]
Where:
[tex]A=Amplitude=\frac{|A_m_i_n-A_m_a_x|}{2}\\\omega=Angular\hspace{3}frequency\\\phi=Initial \hspace{3}phase[/tex]
And:
[tex]A_m_a_x=Maximum\hspace{3}amplitude\\A_m_i_n=Minimum\hspace{3}amplitude[/tex]
On the other hand, we can define the midline of these kind of functions as the halfway between the maximum and minimum amplitude of the function, Therefore:
[tex]Midline=M_l=\frac{A_m_a_x+A_m_i_n}{2}[/tex]
From the graph you can see that the maximum value of the function(maximum amplitude) is 2 and the minimum value of the function (minimum amplitude) is 0, thus:
[tex]A=\frac{|A_m_i_n-A_m_a_x|}{2} =\frac{|0-2|}{2} =\frac{|-2|}{2} =\frac{2}{2} =1[/tex]
And:
[tex]M_l=\frac{A_m_a_x+A_m_i_n}{2}=\frac{2+0}{2} =\frac{2}{2} =1[/tex]

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin.
r = 5 + 4 cos θ
Explaining how to determine the symmetry of a polar graph based on the given equation r = 5 + 4 cos θ.
To determine the symmetry of the graph r = 5 + 4 cos θ, we can substitute (-θ) for θ in the equation and check if the resulting polar equation remains the same, indicating symmetry about the origin.
If replacing (-θ) gives us the same equation, the graph is symmetric about the y-axis. If replacing (π - θ) gives the same equation, then the graph is symmetric about the x-axis.
In this case, replacing (-θ) in r = 5 + 4 cos θ gives r = 5 + 4 cos(-θ), which simplifies to r = 5 + 4 cos θ, indicating symmetry about the y-axis.

Sina played basketball on a rectangular court that was 74 feet by 42 feet. after the game, she walked across the court diagonally from one corner to the opposite corner. approximately what distance did sina walk in feet?
Distance walked = 85.088 feet
The distance Sina walked would be equal to the length of the diagonal of rectangle.
As every angle in a rectangle is 90 degree. So, we can apply Pythagoras theorem in right triangle formed by sides,
Base- 74 feet, Altitude- 42 feet and Hypotenuse- Diagonal
Base^2 + Altitude ^ 2 = Hypotenuse ^2
74^2 + 42 ^ 2 = Diagonal ^2
On solving,
Diagonal = 85.088 feet
To calculate the distance Sina walked diagonally across the basketball court, we utilize the Pythagorean theorem using the court's length and width. The calculation gives us a diagonal distance of approximately 85 feet.
To calculate the distance Sina walked across the rectangular basketball court diagonally, we can use the Pythagorean theorem. This theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Since the court is 74 feet long and 42 feet wide, these dimensions can be considered the two shorter sides of a right triangle, with the diagonal Sina walked being the hypotenuse.
The Pythagorean theorem formula is:
[tex]c^2 = a^2 + b^2[/tex]
Where c is the length of the hypotenuse, and a and b are the lengths of the other two sides. Substituting the known values:
[tex]c^2 = 742 + 422\\c^2 = 5476 + 1764\\c^2 = 7240[/tex]
To find c, we take the square root of 7240:
c ≈ 85.09 feet
Therefore, Sina walked approximately 85 feet diagonally across the basketball court.

2,400 principal earning 2%, compounded annually, after 7 years. Find the balance in the account
The balance in the account after 7 years will be approximately $2,747.70.
How did we get the value?To calculate the balance in the account after 7 years with a principal of $2,400 earning 2% interest compounded annually, you can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the future balance
P = the principal amount ($2,400)
r = the annual interest rate (2% or 0.02 as a decimal)
n = the number of times the interest is compounded per year (annually, so n = 1)
t = the number of years (7 years)
Plug these values into the formula:
A = 2400(1 + 0.02/1)^(1*7)
A = 2400(1 + 0.02)⁷
A = 2400(1.02)⁷
A = 2400(1.144877)
A ≈ $2,747.70
So, the balance in the account after 7 years will be approximately $2,747.70.
